This is a masterful piece of financial engineering by Google and SpaceX.
Google purchased 10% of SpaceX over a decade ago. After dilution they probably own around 5%.
SpaceX is valued at a whopping 94x revenue. This deal increases SpaceX's revenue by $11 billion per year. If SpaceX maintains this revenue multiplier, then this single deal boosts SpaceX's valuation by 94 x 11 billion = $1 trillion dollars. Google owns 5% of SpaceX, so they make 50 billion dollars. Google spends 10 billion and makes 50 billion, $40 billion profit.
The even better part is that because of this deal, SpaceX is now profitable. The S&P requires companies to demonstrate 12 months of profits before they can enter the S&P 500 index. SpaceX lobbied to have this profitability requirement removed, but S&P said no and refused to rewrite the rules.
Now with this incredible deal, SpaceX is now GAAP profitable under the existing rules, and they get to join the index next year without a rule change.
I sincerely hope the market is not willing to value this sort of deal at a P/E ratio anywhere near 94.
Off the top of my head, there is a very well established business involving buying expensive things and leasing them to the companies that intend to operate them so they can sell services: aircraft leasing.
AER is the biggest player and they have a P/E ratio of, drumroll please, 6. And I expect that GPUs, despite currently looking like an appreciating asset, will actually depreciate faster than aircraft in the long run.
Yeah, only a small portion of SpaceX's revenue actually comes from Space (payload delivery). At this point they are basically an ISP (Starlink) and a datacenter/leasing company.
It's not clear if Musk (SpaceX/X.ai) is really pursuing AI any more - I expect he hasn't necessarily given up on it, and he hasn't said he has, but it seems he's rented out almost all of his GPUs to Anthropic and Google, so that's not going to be much of a revenue generator, at least for time being.
The profit center, to the extent any division makes money, is Starlink, yes, but what we have always known as SpaceX is just a tiny side project in the combined company.
According to their IPO S-1 draft they are 93% an AI company and 4% a space company. Its the remaining 3% of the company that is profitable, the Starlink stuff.
Comparing SpaceX to an aircraft leasing company seems more foolish to me than a 94x multiple.
I understand the gist here, but come on. This is a generational company. It’s the only relevant space launch business, and has its tentacles deep in AI infrastructure as well. Maybe the AI bet is foolish — I don’t know — you should short it!
I am comparing SpaceX’s datacenter-and-GPU leasing business to aircraft leasing.
It’s possible, and common, for one large company to have multiple business lines, each worthy of a very different P/E multiplier. In principle you end up with a weighted average of some sort.
edit: Matt Levine has some great articles about this phenomenon and how some companies try to juice it.
I would short xAI but the market can remain irrational longer than I can remain solvent. Plus all the foolishness to prop it up with other businesses just seems like bad accounting.
I don't think you can short it before the IPO happens. Well, unless you've got a few millions and go to a bank and have them make a product for you specifically. But for normal people, for now, not happening.
Except for people who have pensions/investments in whole market class investments who become exposed to an over valued company with a propped up value.
If whole market means whole market, then such investments are exposed to companies who are fairly valued, companies who are massively overvalued, and companies who are massively undervalued, and the whole range in between.
If you want to start picking and choosing which companies are overvalued and which are undervalued, don’t invest in whole market funds. But most people are not good at that!
The Nasdaq 100 and FTSE Russell made a rule change that allows SpaceX to enter index without mormal time for price discovery. Most index funds have rebalance day just 5 days after IPO. S&P also made rule change for S&P Total Market Index and Dow Jones US Total Stock Market Index, but left SP500 intact.
Nothing wrong with SpaceX or Anthropic getting into indexes with fair rules, this rule change is pure creed+corruption.
Fun fact, both Enron and Lehman Brothers were in the S&P 500 when they went bankrupt. So yes, the whole market or even the market of the largest companies, includes some that may not be great companies. The beauty of the index is you don't have to know or care, since it'll take care of itself over time.
Also, there’s a long history of companies that people yell about being overvalued being the drivers of index returns, because one of the major drivers is growth rate, whereas retail investors tend to look mostly at current state.
The key there is "whole market." This is still a tiny sliver of the whole market and most people's exposure to it is minimal. Still a wealth extraction move ultimately, but like many other such moves, the few pull just a little from each of the many. Nobody individually goes broke, but the whole class gets slightly poorer. It takes a village to raise a billionaire!
Alternatively you may want to be a passive investor using the current rules for index inclusion, rather than having them altered to favor this loss-making trashcan on fire.
> SpaceX is trading at a whopping 94x revenue. This deal increases SpaceX's revenue by $11 billion per year. If SpaceX maintains this revenue multiplier, then the single deal boosts SpaceX's valuation by 94 x 11 billion = $1 trillion dollars.
That final number doesn't make sense: if you're trading shares at $X revenue, increasing the revenue by $Y multiplier doesn't increase the share price by the same multiplier.
I rreally dislike how big corp figured out that the can sell stuff to each other without actually moving some good. Looking at you, Nvidia... I have a feeling that the ordinary people will again pay for that.
The problem described isn't companies buying goods and services. It's buying from an entity they partially own and then profiting as that entity becomes more valuable because of the purchase.
Yes, if it's done with an intent to defraud the general population, which could be the case here. Effects and intent really matter when deciding actions.
Except the regulators first outlawed what is generally considered to have caused the great depression (savings banks allowed to invest, which translates to very, very rich people being allowed to take massive risks with poor people's money) ... then re-legalized it.
So not only are the regulators not going to allow things that cause another great depression, they're allowing the things that caused the first great depression too. They must want a rerun.
(Because if you don't allow this you're effectively demanding the extremely rich make good investments to stay rich ... and not even France, otherwise pretty socialist, dares to go that far)
I mean, we all understand that this is some sort of circular financial play, but at the end of the day Google is paying SpaceX $1 billion for compute. This is no different from AWS or Azure.
> SpaceX is now GAAP profitable under the existing rules
We'll need to see audited financials, but if this part is true people are going to be upset. I wonder if all the people who have been acting like the S&P rules came down from the mountain with Moses will start lobbying to change them to keep SpaceX out?
And to be clear, I think SpaceX is way overvalued and I wouldn't buy it stand alone. But there are a lot of companies in the S&P 500 I wouldn't buy stand alone, yet I still own a a lot of an S&P 500 ETF. /shrug
As an ignoramus to these things.... there are only just so many Googles though. Having made a significant jump, are they really expected to continue that growth?
Google and friends continue to see increased demand for their wares. The bet is probably that SpaceX is one of the best-placed companies to deliver incremental compute. They've shown they can build data centers fast.
The bet is that demand for AI tokens will continue to grow exponentially. And that SpaceX will be able to deploy and rent out GPUs to serve those tokens faster than anyone else.
The wrinkle is that they are planning to deploy those GPUs in space. That’s what people are most skeptical about, I think!
Space data centers need years of time to design, build, and deploy, 5-10 at least, and that's after they solve their multiple very difficult or impossible problems. How will they cool them? There are just simple ideas like giant structures to radiate the heat away, but you say you need to put lots of mass in orbit?
Well yes it will be hard, and hence maybe not economical, and that’s why many people are skeptical of the business case (myself included btw).
But satellite cooling already exists (Starlink v2 satellites dissipate heat at over a kilowatt I believe), so that’s why other people find it plausible.
They also need Starship at minimum, which is now a 10+ year old project still exploding regularly.
Starship is at minimum a 2030 project at this point.
And even producing the volume of chips needed for the type of growth space data centers would need to have to justify this would be another decade if construction started now on those fabs.
I don’t think your math is correct. Profit is revenues minus expenses. Unless Google’s purchase of compute brings SpaceX’s revenues into profit territory (such that their total revenues exceed their expenses), SpaceX still won’t be profitable. This is accounting 101.
Google’s investment in SpaceX is completely orthogonal to the analysis. Equity investments aren’t revenue for the issuer. (Gains on sale would be revenue to the investor, in which case, this would be Google, not SpaceX.)
SpaceX cannot report Google’s investment as revenue on its balance sheet. Full stop. Equity investments are reported as shareholder equity. If you don’t believe me, ask your friendly neighborhood CPA—or, perhaps so you’ll earn a valuable lesson about confidently spreading bullshit about subjects in which you are clearly uneducated (or, best, superficially educated), try it yourself in a public company and go to jail.
You don’t know what you’re talking about and are way out of your lane. Stop now. In fact, you should retract your parent comment and apologize to the community for leading them astray.
Did you even try to ask even ChatGPT or Claude about this first?
For your math to make sense, Google would have to sell its stake this year
There may be more to it than buying compute but what you're saying does not make sense for Google. More likely Google wants a good relationship with SpaceX and possibly to buoy the stock, but it's a bad NPV trade
> this single deal boosts SpaceX's valuation by 94 x 11 billion = $1 trillion dollars
That's not how valuations work. Also, it is not unlikely that SpaceX's valuation drops post-IPO (tech was 6.65% in the most recent trading session) due to its very rich valuation and a long tenured investor based that is probably looking to get liquid.
Google is renting compute from SpaceX because they need GPUs and SpaceX owns a huge supply of them and has excess capacity bc no one uses Grok. Google has stated that this is a temporary arrangement while they continue to build out their own capacity.
So masterful that a random guy on HN can see right through it.
Let’s just call it what it is. It’s just basic fraud. They created a very temporary revenue injection right around the time of the IPO to defraud investors as much as they possibly can. Some businesses do this kind of thing just before they die because…why not?
Utterly nauseating. Why would google help prop up this company and its figurehead? Maybe this is finally the straw that breaks the camel’s back for me and google.
It seems like Silicon Valley has decided on solidarity among tech billionaires and they're gonna take average Americans' wealth to keep themselves semi-relevant globally as China assumes global dominance. This is after insulting and demeaning the rest of the world, they plan to try to sell anemic services to other countries in whose politics they're also meddling. Circular agreements promising to purchase goods and services without the money in the bank, but you can show your promissory note to a guy with his own promissory note who then writes you a new promissory note based on your first one to take to another guy with his promissory notes, look at all the paper.
Except they’re paying $30b (the deal is signed for almost 3 years), there’s no reason to believe that SpaceX maintains revenue multiples and this deal creates a trillion in value, liquid cash is not the same as pre-IPO shares. And finally, the deal comes down to $11 per hour of h100 equivalent, which is pretty much within market which experiences a severe lack of supply.
Since the S-1 filing, xAI has taken over and is likely the largest share of revenue. I would estimate that ~95%+ of xAI revenue, and 100% of its profit, is from renting their datacenters.
This is a datacenter REIT bolted onto a social media company bolted onto launch business bolted onto a niche ISP. The expected price to sales is ~100x. The best datacenter REITs trade at ~10x and pay a dividend, which SpaceX does not. Meta trades at ~7x sales. Comcast is one of the best-run ISPs, and it pays a 5.5% dividend on a stock trading at < 1x sales.
To say SpaceX is overvalued is to even beginning to convey the magnitude of the situation. It's going to be very painful when the valuation normalizes.
TSLA has a forward PE of ~200x. That is probably the most logical comparison with SpaceX. Proof that the market can stay irrational for quite a long time.
It fills me with a bit of dread about the future of the market. I am 10 years out from retirement, have a bit over 1M sitting in that market, and I wonder if it will implode in the meantime. I am fairly committed to the "invest like a dead man" (i.e. index funds, no touch), but the world we live in today makes me have real doubts that the next few decades will look anything like the last few.
About 10 years out as well. I’ve concluded I just invest a very balanced set of index funds and bonds and GICs across a handful of institutions, and then invest in my home because even if the housing market collapses I get to enjoy my nice home.
Other than that I’m just not over investing for retirement and instead making sure the money is spent today on family growth and experience.
I eventually just got tired of everyone with an opinion on what doing it right looks like or how to predict the market.
Circular financing at its finest. And Self-dealing between the hyperscalers, openai, and anthropic.
google invests in anthropic and spacex - and shows appreciated values as earnings. Then it turns around and rents tpus to anthropic to show it as revenues. The main buyers and sellers for all of this are the hyperscalers, openai and anthropic.
It is a game of musical chairs while the party is still on.
Do companies like Uber, Tesla, etc ever intend to pay dividends? If a stock never intends to pay dividends, the value of the stock is simply the price the next shumck is willing to pay.
The value of the stock is your share in the underlying business. Because underlying business changes over time (hopefully for the better) you are not simply hoping another shmuck pays you more, like with tulips, whose underlying value does not change with time. You own a portion of a concern that is improving its own fortunes.
Furthermore, dividends are approved by the board once per quarter or once per year. A dividend on a stock is not a contractual guarantee like it is on a bond. Therefore, it cannot be a basis of value.
With your logic, Berkshire Hathaway is a long-running greater-fool tulip bubble whose shares are only bidded up by finding more shmucks.
That’s the story, but it’s bullshit. The underlying intrinsic value of a stock can only be materialized if the company liquidates and you receive a share of the sell off of its assets. How many publicly traded companies abruptly decide they’re tired of the business, stop in their tracks, and liquidate their assets? This only really happens if the company is acquired or if it goes bankrupt. Acquisition is the closest the story comes to truth, but it’s also just forced sale to a greater shmuck. If a company goes bankrupt, a tiny fraction of the current stock price would be realized into cash for common investors because of all the privileged investors and lenders ahead of them, not to mention that the actual value of capital assets etc probably doesn’t cover all the losses (the company’s going bankrupt after all). The value of the underlying capital assets are essentially never returned to the common investors, and the idea that you own a portion of them is in practical terms a lie.
Well, the value of the stock for people who essentially do not have any meaningful control of the business must essentially be tied to the expectation of some liquidity event down the line -- future cash flows. So this could come in the form of dividends, sale of the stock, bankruptcy proceedings, or a purchase of the business.
If I knew for certain (big if) that a business would never have a liquidity event and I couldn't transfer my ownership then it's dead capital for all intents and purposes and you could consider its value essentially $0, right?
Excellent question. They may not intend, today, to pay dividends. However, the same question could have been asked about the successful tech companies of the '00s. Companies don't like to start paying dividends until they are fairly certain of their future profit stream and therefore ability to continue paying (and increasing) the dividends in the future.
Apple, Oracle, Nvidia, Cisco, Alphabet, Meta, Salesforce, and Qualcomm all pay dividends now. It's not unreasonable to expect Uber and Tesla to pay in the future. However, the median time after IPO for similar companies to pay a dividend is close to 20 years. So we could expect Uber to perhaps wfstart paying sometime around 2039. Tesla...is Tesla so who knows?
Google renting infra from xAI, I did not see that coming. My understanding of what computers are doing, what companies are doing and what governments are doing seems to be getting worse day by day.
> Google renting infra from xAI, I did not see that coming.
Actually that seems to be fairly logical? Hardware is what xAI has, and it's in great demand. So sell what makes you money. The real story here is that that xAI hardware is going to be running Gemini and not Grok. Which is to say: Grok basically failed as a frontier AI and they need to pivot to a business model which makes money.
Obviously not everything Musk did was wrong. xAI bought a ton of compute when it was possible to get it. But the product they were going to build with it failed and so now they're deciding to be a landlord.
This IPO is just insane. No way do you justify a $trillion+ valuation based on what amounts to a bunch of commoditized rent seeking endeavors. Datacenters are buildings and chips, and everyone can build those. Starlink is just an ISP with lots of competition at scale (they have the high bandwidth mobile market cornered, but that's a very small market!). Mars is at best a grift on public funding. Even satellite launch services are commoditized and competetive these days.
Keep in mind Google also rents GPUs via GCP, so they could be just reselling these to GCP customers?
Thing is though, Anthropic was really against the wall with lack of compute pre xAI deal. And tbh, Gemini reliability has been abysmal which probably points to real compute shortages.
And nearly _every_ major DC project is really up against it with massive delays, etc. Stargate UAE has been badly affected by the Iran conflict.
So maybe long term this isn't a great business, but _right now_ I'm not convinced it's all financial engineering. There is a enormous shortage of compute and xAI has a load of it _available now_.
> Which is to say: Grok basically failed as a frontier AI and they need to pivot to a business model which makes money.
They can just run Grok as a local AI inside Tesla cars. It's actually really efficient as a compute platform because the Tesla cars are in motion at highway speeds, which gives you lots of free airflow for shedding waste heat via the car radiator. Way more efficient than trying to run AI on space satellites.
Anecdotally, Grok is mostly not that anti-woke. It is coasting off of its reputation from Elon's marketing. That said, it does have meaningfully fewer guardrails, which is a real benefit.
I am pretty sure the gov gets an uncensored /heretic version of the AI models instead of the nanny stuff we get so Grok really doesn’t have a “killer” feature. Even for multi model passes(I.e used purely as a contrarian gate) it’s not really that great due the high rate of hallucinations.
Who’s going to be paying for the energy? People have been floating using the cars as compute for years and it just doesn’t make any financial sense for anyone.
Teslas spend a tiny percentage of their life at highway speeds, and a major selling point of the platform is that their compute would be used to pilot the vehicle.
If they could train using Teslas they wouldn't have needed Dojo.
You make it sound like they’ve given up on Grok, which I don’t think is accurate. I think it’s been mentioned the Grok 5 1.5T model is currently training on Colossus 2. And their recent deal with cursor is part of being able to eventually compete with Anthropic for agentic coding.
Strongly agree with all of this, except that charging rent for the use of an asset you own is not what economic "rent-seeking" means. I blame the dumbass economists who named it this, forever polluting the discussion to be had about regulatory capture and legalized political bribery.
The future needs more AI compute. No one has enough AI compute.
Memory chip vendors are betting hard on this being a temporary state of affairs that doesn't last, and doesn't warrant commissioning a shitton of new memory foundries.
Musk is betting hard on this staying that way, and is putting the next Colossus into the last place not corrupted by NIMBYs... SPACE!
A huge chunk of SoaceX value in their filing is attributed to their AI technology (aka Grok). I believe it’s 90% or more… Now, it seems they’re leasing the infrastructure required for Grok to scale to Anthropic and Google. I wonder how that math works…
But what is xAI? I thought that was the company that had the compute + Grok, the AI company? Since when does SpaceX (which I thought was a space company?) own AI-compute hardware and/or can do model hosting? Are all of Musks companies just one big thing now where the names no longer matter, or how is it supposed to work?
Edit: seems I'm just a bit behind: "xAI — now part of SpaceX ", seems really strange for a space company to buy an AI company, but I guess rather that, than the other way around.
Musk sold Twitter into xAI which he then sold into SpaceX as a financial engineering effort to lessen the impact of massive debts and cash burn. The IPO and some clever structuring is the final step in the process.
Not really strange... if the goal is to go to mars, you probably need robots, those need intelligence -> ai. It fits pretty well, especially because you want to own all the core technologies as a company.
Why 4-5 companies instead of one then? I thought the goal of SpaceX was to get to Mars, why does xAI need to have that same goal? Or he didn't think xAI was suitable for that goal, then changed his mind so merged the companies?
You are overthinking this. The whole purpose of the SpaceX / xAI merger is for Musk to launder his failing companies to make them more palatable to the public. Not unlike the complex Mortgage Backed Securities of the GFC era which had a ton of low quality debt but yet were somehow assigned spotless credit ratings. Twitter is also being rolled up into SpaceX for the same reason.
The stated goal is to "go to mars", the real goal is to make money.
He sold his failing but hype business to his soon-to-IPO successful but kinda boring business.
It's a way of laundering the debt and dumping into investors as he pitted different indexes against each other to force his way into one of them, and have people's 401k buy into them. Its a ton of money.
I wouldn't be surprised if Tesla is bought into spaceX in the future.
It has nothing to do with Grok, at least not the current iteration. SpaceX is the only company that can concievably launch large scale orbital compute.
I’m out of the loop, why is compute better /after/ being launched into space? Is the idea just to be co-located within the ISP to reduce round trip time to the LLMs?
> $920 million per month from October 2026 through June 2029 for access to “approximately 110,000 NVIDIA GPUs, CPUs, memory, and other related components.
That's about $8,400/month per "component" is that in the ballpark at all with what a month of dedicated/exclusive access to an NVIDIA GPU would go for?
Makes a lot of sense that Musk should do the parts of the AI stack that look more like manufacturing/regulatory bottlenecks, and rent out the compute to research-focused AI labs. Does anyone know the full accounting of how much it cost to build Colossus (plus ongoing opex) vs. the revenue it's generating now?
Is there any data on whether Google, Amazon, Microsoft, Anthropic, OpenAI etc are most cost efficient in getting datacenter compute online and operating it?
I'd be interested in how large the range is here across company and region and specific data center and how it relates to companies like Hetzner if at all.
Well, Elon seems to take the fastest path possible to these DCs. One can envision a future where these get shut down for the severity of the pollution, not to mention being built and operated illegally [0].
> Is there any data on whether Google, Amazon, Microsoft, Anthropic, OpenAI etc are most cost efficient in getting datacenter compute online and operating it?
Well considering that ~80% of the price is hardware deprecation, I don't know why they'd be considerably worse than anyone else at negotiating hardware deals.
Typically when you buy in bulk, you have more sway.
Companies like Google also have in-house chips like TPUs that are substantially cheaper for inference for them to make than anyone else can get through Nvidia.
I’ve seen some numbers related to datacenters in Ireland and they would stress price per MW as a way to see where to build them. But then you have depreciation of equipment as well. Depreciation can be played with when filing taxes though.
I don't think they are most efficient for small GPUs. I think they might only be the one which have capex and certainty required for multimillion dollar purchase of GB200 NVL72 or something of that scale.
SpaceX valuation and ultimate success depends on two things:
1. AI demand continues to grow.
2. SpaceX's orbital data centers are profitable.
If both of those are true, then their current valuation is absolutely justified. I'm confident #1 will happen.
#2 is the big bet, and IMHO this is just an engineering/execution problem. All they need is (a) Starship to work reliably, and (b) a manufacturing line that can build a data center satellite at low cost.[1]
(a) is the harder of the two, IMHO, but they are well on their way. Once they successfully recover and refly a Starship upper-stage, they will iterate step-by-step until launch costs drop to the level they need.
Now assume that SpaceX succeeds. What if AI demand continues to grow and SpaceX orbital data centers are profitable? Think of their moat: they spent 10 years and billions of dollars developing a fully reusable rocket that happens to also be the largest rocket in the world, and that costs 1/10th of what other rockets cost (per kilo to orbit). Plus, they have an assembly line that can build data center satellites cheaply, and they start fabbing their own AI chips.
How is anyone going to compete with that? There are a bunch of data-center-in-space startups, but none have their own rocket--they're going to have to pay SpaceX to launch them. Blue Origin is developing a rocket as large as Starship, but it's not fully reusable--they will never get the cost down to Starship levels.
What's interesting is that all the AI companies, OpenAI, Anthropic, and even Microsoft and Google, are mostly leasing their data centers from someone else. They think compute is a commodity and the value is the trained model. But if SpaceX has the cheapest data center with the most capacity, they will be able to extract profits from the AI companies or (why not) compete against them with their own model (Grok).
In 10 years we'll see whether SpaceX succeeds or fails. If they fail at this, they will retrench back to a launch company (assuming they are still in business). But if they succeed, they will be a massive company, and the synergy between their businesses will be so obvious that everyone will say, "of course they succeeded!"
----------------
[1] Don't be distracted by claims that "cooling in space is hard" or "radiation is a deal-breaker". Neither of those are insurmountable problems--they are just engineering problems. Crucially, they are problems that are easily solved by getting mass to space. If you can get mass to space cheap enough, those two problems are trivial to solve.
Why would you want to own your own giant datacenter? What would you do with it? Of course it's expensive to operate a datacenter that serves millions of people.
> As part of that deal, Anthropic agreed to pay SpaceX $1.25 billion per month through 2029 to rent all the available compute from its Colossus 1 data center near Memphis, Tennessee, that xAI — now part of SpaceX — originally built for its own artificial intelligence efforts.
I don't get why SpaceX is going public. But anyway, well played, the whole crypto mining that dried out GPUs back in the day seems tiny now.
Liquidity for investors. They raised everything they could from private markets, government contract, debt, the remaining source of financing is from the public
These deals are part of how the AI economy operates. Amodei has explained this in his recent Patel podcast.
1. Building datacenters takes time. Months, if not years. They take billions of investment.
2. AI revenue is highly unpredictable. Sure, you can make predictions, but maybe your competitor releases a better model 2 weeks after your release, maybe the new model you built isn't as much better, maybe the chinese models steal your show, etc.
3. AI revenue grows a lot. Anthropic's case is 10x per year.
4. So if you are off by just a year in terms of how much GPU you actually need, then that means a 90% of your compute capacity is wasted, and you go bankrupt.
As a solution, companies buy compute from each other! If one company's model did well, they can buy compute from the company whose model didn't do well (like in the case of grok). It's beneficial for both sides, so positive sum game. So deals like this aren't something bad in itself.
It's nothing new either. In SAAS deals, you often commit to a certain revenue and then pay extra if your revenue exceeds that amount. And power market is cut in two as well: longer term deals plus spot markets. Spot prices are way higher than the longer term deal prices.
Given it's SpaceX of course there is financial engineering involved: the GPUs aren't actually owned by SpaceX but a daughter company, and it's been financed via loans that are backed by pension funds. So it's already the case that pension funds back bear the risks associated with SpaceX's operations.
Right now, the bulk of the AI bubble sits in such debt statements and not in public markets.
“If we fail to deliver access to the committed amount of GPUs by September 30, 2026, then following a one-month grace period, Google may immediately terminate the agreement or accept the number of GPUs provided, with a corresponding pro rata reduction in the monthly fees. After December 31, 2026, the agreement may be terminated by either party upon 90 days' notice.”
SpaceX has recently started pitching itself as an orbital datacenter company.
If you buy into that business model (or pretend to), it makes sense for SpaceX to start selling compute early. Their "earthside compute" clients of today are "skyside compute" clients of tomorrow.
A part of Musk's old pitch for Starlink was: space-based solar makes perfect sense for powering space assets, and no sense whatsoever for powering Earth assets. So you have to find a way to use that power in space to do something economically useful. Comms were the only scalable way to do that, so Starlink it was.
I can see how space-based datacenters would follow the same logic. If SpaceX can make them economical, that is. There's no guarantees of that - but if anyone at all can make space-based datacenters economical, it's SpaceX.
> if anyone at all can make space-based datacenters economical, it's SpaceX
Let's hope burning ten thousand tons of toxic e-waste annually in upper atmoshphere never becomes economical. Or mankind gets to senses and bans externalizing your e-waste problem by burning in atmosphere...
> ...burning ten thousand tons of toxic e-waste annually...
Expressing water usage in gallons makes it seem really large, too. NASA says[0]:
Scientists estimate that about 48.5 tons (44 tonnes or 44,000 kilograms) of meteoritic material falls on Earth each day.
If we assume that they're all the heavier v2 units, the total mass of the orbital portion of Starlink is ten point four tons. [1] If we assumed that they lasted one year (instead of the five that they're reported to last[1]), then over the course of a year, Starlink would dump six hours worth of asteroid collisions into the atmosphere.
I think we'll be fine. Pour all that frustrated energy you have into substantially reducing the amount of incredibly hazardous d-waste [3] big commercial operators burn up into our atmosphere, instead.
I think you missed a factor of 1000 somewhere in there: Each satellite weighs about 1 ton, there are about 10,000 of them. That is 10,000 tons in orbit for the constellation, not 10. Assuming a 5 year decay, that's 10000/5/365 ~= 5 tons / day. Still about 10% of the natural incoming material, but considerably more than your "six hours worth per year".
There are no NIMBYs in space. No government permitting on land use. And solar power is plentiful. It's like having a dollar store Dyson sphere.
Making use of that is predicated entirely on being able to put a lot of hardware into space cheaply. SpaceX is the undisputed best at that, no one comes close. The question is whether their "best" is good enough to make space datacenters economical.
There are many Not In My Orbit people on this very page. Many current national politicians would be happy to vote AI out of orbit today. Space is not an escape from earthly politics.
I am surprised how many people say that there is no reason to put data centers in orbit, when, at the same time, data centers are becoming the hated thing du jour all over the US and politicians left and right (but mostly left-of-center) are touting bans and restrictions to their electorates.
It is definitely to escape most political pressures on Earth. They will never be able to sidestep the US feds, but aside from an open war with China or Russia, all other authorities are out of the game when it comes to space.
My job is mostly worrying about cooling paths, maintenance, power, heat transfer, lifetime of GPUs, and high performance networks. NVIDIA partner. I can drive to the datacenter. This stuff BARELY works here on Earth. Especially thermal issues.
Looking forward to watching spacex defeat physics.
Evaporative cooling is the way it happens down on earth - and that shuttles h2o molecules from dense useful clumps like aquifers and rivers to a less useful form spread out in the air. But evaporating h2o isn’t an option in space afaik - since there’s a shortage of air to take up the h2o. In fact I think radiative cooling is the only actual option in space.
That's the neat thing: you don't, or at least not in the megawatt range. A kilowatt can be done with radiative cooling but doesn't get you far with a hypothetical datacenter satellite.
No; if you try to do this you don't launch in the first place because the amount of servers required to be useful can't be cooled within your payload budget.
The data link between earth and space has so much bandwidth.
There are sensors in space that send data to earth it gets processed and then the data is sent back to space then to the end user back on earth. If you do the compute in space you save the space-earth transfer time twice. Latency and availability of bandwidth are both factors.
There may be limited utility for this outside of military.
Musk is a snake oil salesman (that’s been clear since the self-driving car promises) but he also has made a lot of people a lot of money and that’s all anybody really cares about.
None of his companies have a traditionally reasonable valuation. Is there any reason to think that’s going to change soon?
Can anyone explain how the thermals will work? One of the biggest challenges on Earth is cooling the data center, and it's at least as challenging in space.
It won’t. It’s not supposed to work, it’s a mirage to raise dumb money. It’s way, way more challenging to cool something a vacuum. The only option is radiative cooling, which is far from being performant. The idea is as realistic as Musk previous grifts such as his digging company and there hyperloop, both absurd and supposed to revolutionize transport, both created as grifting devices and ensure public transport doesn’t develop in the US
The earthbound equivalent would be strapping each chassis to the back of a dedicated solar panel and having the panel double as a giant heat sink. The problem is that doesn't work on the surface due to (at least) rain, the day/night cycle, and the cost of real estate.
But it doesn't matter since in this scenario each chassis is powered exclusively by the respective panel. How hot does a black panel sitting in the midday sun get? That's your equilibrium temperature. As long as it's within the operational limit of the device there's no problem.
The reason earthbound DCs are difficult to cool is because of density. When you match up panels to devices and shelter in their shadow you no longer have anywhere near the same power density.
There are asteroids with concentrations of precious metals more valuable than earth's entire economy. Why don't we just send up spaceships to mine them and send the haul back to earth? What country would say no to free money?
After all, it's just an engineering challenge, not impossible.
The numbers on that are at least somewhat questionable. Even ignoring that you'd crash the market (thus it's not actually worth what it first appears to be) what is the total fuel cost to adjust the orbit of the target asteroid to land the entire thing back on the earth? Because that's what you're doing bit by bit as you shuttle loads of ore back.
Now if you have space based manufacturing or fuel production on the other hand ...
When I hear space I think "that's the perfect location for a data center", since data centers are lightweight, small, require little power, don't need human intervention, have lifetimes measured in decades and don't have to reject heat. Since space easily satisfies these requirements, space is an ideal deployment location for data centers.
Isn't the Vegas Loop just a car tunnel? As far as I know, there aren't any actual hyperloops[1] involved, just a narrow highway, even if they deceivingly brand it "Loop".
It seems off at first glance but actually appears to work out if you do the math. You can model a solar panel as a flat, opaque rectangle. You can calculate power generation and equilibrium temperature for it based on surface area. If you require additional radiative surface area to achieve the desired equilibrium temperature you can place a flat triangle orthogonal to and behind the solar panel in its shadow.
Compute is "free" at that point because waste heat is coming out of the total energy flux which was already accounted for (because we modeled it as opaque).
Of course swapping out the equipment poses a bit of a challenge. The "helping hands" rate is entirely unaffordable and wait until you see this new DC's physical access policies. 0/10 would not rack with them again.
This is all just the typical Elon hate. What's desperate about getting paid $920,000,000 per month? If that's desperation, I'd love to start groveling more!
Given extreme supply constraints, it's very unlikely that Google or Anthropic will just suddenly cancel right after the IPO unless their own demand collapses. And even if this were true, what value would that provide Musk? Could you imagine if your newly public company suddenly received termination notices from your two largest compute customers? Disaster.
I have no love or hate for Elon Musk. I wish him luck with his space endeavours.
What's desperate is announcing a temporary (allegedly) doubling of revenues days before an IPO that has been criticised for being overpriced at 93 times sales.
These data centers were supposed to serve xAI. Now suddenly they get rented out to others. Why the sudden change of plans?
It's either an emergency accounting gimmick or the effective shutdown or repurposing of xAI.
It’s a repurposing of xAI to be a commodity service provider during a crunch for that commodity. It would be dumb if xAI had any quality or market traction, but they have neither, so it’s actually a rational fallback. But it writes off any high margin future in favor of low margin scale.
And once the compute crunch is over, they’ll have a lot of overprovisioned data centers with no business to soak up the capacity.
Didn't Anthropic pull the same in both ways? you pull me up I pull you up kind of deal? Sounds like SpaceX bought themselves some time up to Q4, which is not the case of Anthropic and even worse for OpenAI. Not counting that none of them got their S&P500 fast-track ticket.
If you look at the IPO filings you’ll see that Spacex as we know it is just a small part of the expected revenue generator. It is supposedly Grok and AI, hence Google competitor.
All companies are now AI companies.
Just like a while ago all companies were suddenly Ads companies.
The entire tech sector is one big FOMO - once you reach certain scale you do exactly the same thing as everyone else.
I get what you mean but SpaceX owns xAI, which is objectively a company that trains models and has massive distribution by owning X.
I don’t think their models are competitive with Google, and Google obviously has the best distribution imaginable, but they definitely are a competitor.
Their satellite internet business is the only thing which makes them money, which is enabled by their orbital launch business which is as of right now not profitable and I have no idea of if it ever will be but without it they would not be able to launch enough satellites.
Their stupidity with AI and buying X mostly seems to be about scamming investors to make Musk even richer. Like this particular deal is just them doing what CoreWeave does at a SpaceX valuation.
Launch isn't profitable simply because ongoing Starship R&D is eating into it. A lot of opex, capex, and pre-revenue.
If they start running Starship anywhere near the way they do Falcon 9, it'll flip into profits. A lot of big bets SpaceX made ride on Starship coming online. I'm honestly surprised Starlink is already so profitable without it.
One of their big named bets includes: orbital datacenters. Which puts this specific deal into perspective.
80% of the space launch business is putting starlink satellites into orbit, so it's all internal funny money. They could very well be letting the space launch business take losses to make the satellite internet business look better (only profitable part of the whole thing).
Wasn't starship supposed to be funded by the NASA contract?
Sorry, I was unclear. With that I did not talk about this particular deal. This particular deal seems sane. XAI built more compute that they can use themselves since Grok is not very successful so to not just have the hardware standing there they rent it out to competitors. Makes total sense.
It is other things Musk has gone with Twitter and SpaceX which are shady.
That's only about 35% more than the main telecom operator here in Belgium (Proximus: $7.2B revenue in 2025, $2.5B market cap, positive earnings for 15+ years).
Obviously Starlink can and will growth. I'm just pointing out how insane the market cap is, when compared to similar scale "connectivity" businesses.
Profitability of space flight has a hard maximum. It’s not anywhere close to what their valuation would suggest.
There’s a reason Elon keeps trying to get investors to believe his “data centers in space” lunacy, because you need that sort of magic pixie dust to justify why any of this valuation makes sense, let alone have anywhere to go but down.
Starlink terminals are popular, they put them on drones to avoid jamming (Starling jamming exists but not that easy for now). It might be their sales are inflated due to its use at war.
Is this admission that google’s proprietary chips etc. are not cutting it? Why would you need a bunch of nvidia GPUs if you have your own silicon? (AFAIK they have their own for both inference and training do they not?)
How do you come to this conclusion? All it means is that spacex has compute and google does not.
Suppose tpus were theoretically a million times better, but cannot be produced due to supply chain constraints, this action would still be rational.
My personal take is that this really shows how bottlenecked the entire supply chain is. For such an important commodity there are shockingly few players ready for scale.
3 years is quite a short horizon when it comes to semiconductor fabs. Also this article is a dupe, when it was previously discussed it surfaced that after some time either party can cancel with only 90 days notice.
Kinda; while it does show that overall Google's proprietary chips etc. are not cutting it, it doesn't say if the problem is the hardware itself or the factories to make more of the hardware. Without more information, it could be that Google's hardware is 100x the energy efficiency per token, but they can only make enough hardware for 1% of the tokens there's currently demand for: 1% of your product being 0.01% of your costs isn't nothing, but it leaves the other 99% at full price.
Supply and demand? Bubblists seem to think there's an infinite supply of chips, power, and water to make as many chat bots as possible; physics, as usual, dictates limits.
Its because none of the promised Data Center and NVIDIA hardware deployments described in NVDA earnings calls have actually happened. Once more Ed Zitron has the goods: https://youtu.be/zbKDmkJPVvI?t=482
Or alternatively there is simply a huge demand for compute and this is helping them fill a short-term need. Keep in mind if you saw in the article there is a 90-day cancellation clause. This is a nothing burger.
I don't think so. It provides some nice optionality for Google and I am guessing this opportunity only exists because Grok is not popular and xAI does not really have any other use atm.
So Google AI will now be running partly on xAI data centers which run primarily on natural gas burned on site next to poor neighborhoods in Tennessee and Mississippi causing massive air pollution to these families and children. Is anyone else disgusted by this? I’m imagining all the people there developing lung and other issues because of this. Greed and power on full display over doing the right thing.
I’ll be switching off the Gemini model at work (Composer’s been off since their xAI deal). This is the final straw for me to move completely off Google services.
This feels actually like a pretty safe bet for Google, they secure the compute in case it works (I doubt that the described volume will be available in the near future), while if SpaceX doesn’t manage to provide there is not much loss.
I see it more as another way of blowing up SpaceX valuation on paper…
Does this mean that SpaceX are the only company that really did build some datacenters to put all the million of GPU/TPU/whatever they all talk about everyday?
I mean, Google, Amazon, Meta and Microsoft told investors they spent more than $1B per day last year in CapEx... why on Earth do they (well, Google and Anthropic at least) need to rent compute to SpaceX, of all companies?
Other companies built data centers but also built products that soak up their data center capacity.
xAI built data centers, and products that are mostly good for nonconsensual porn and confirming a small group’s biases. So they have a lot of excess capacity, and might as well rent it to the adults.
No, CoreWeave for example also rent compute to the big AI companies. This likely just means Grok has few users so they need to rent their extra capacity to their competitors.
Yes but someone will be along shortly to defuse what sounds like giving the bad mars man credit where it’s due. Like everything else he does that works out, it was just luck, timing, actually a mistake that worked out, or someone else behind the scenes that he got lucky in hiring at the right time (by accident).
Short memory. When musk was buying all of this capacity it was billed as xai is going to take over the world. Instead grok is a flop and now he has extra capacity. If xai was a data center he’d be smart. But it is a failed Ai venture.
It’s like training your dog not to jump on the sofa. But then you fail to train to stay off and then brag about how you trained it to stay ON the sofa.
If your dad had owned an emerald mine I am sure you could also have been that dumb.
But to be more serious: It is impossible to say if this is good or bad for XAI without more numbers. What if they bought their compute way over market price and sell it at a loss?
Cloud companies were made to sell others compute. Now, one is buying billions of compute from SpaceX, a rocket company. That sounds so backwards lol.
Great work by Musk and his companies to be in a position to sell billions to cloud vendors. I'd have probably missed that opportunity while trying to build great rockets or AI models.
This is a masterful piece of financial engineering by Google and SpaceX.
Google purchased 10% of SpaceX over a decade ago. After dilution they probably own around 5%.
SpaceX is valued at a whopping 94x revenue. This deal increases SpaceX's revenue by $11 billion per year. If SpaceX maintains this revenue multiplier, then this single deal boosts SpaceX's valuation by 94 x 11 billion = $1 trillion dollars. Google owns 5% of SpaceX, so they make 50 billion dollars. Google spends 10 billion and makes 50 billion, $40 billion profit.
The even better part is that because of this deal, SpaceX is now profitable. The S&P requires companies to demonstrate 12 months of profits before they can enter the S&P 500 index. SpaceX lobbied to have this profitability requirement removed, but S&P said no and refused to rewrite the rules.
Now with this incredible deal, SpaceX is now GAAP profitable under the existing rules, and they get to join the index next year without a rule change.
Truly a brilliant deal for everyone involved.
I sincerely hope the market is not willing to value this sort of deal at a P/E ratio anywhere near 94.
Off the top of my head, there is a very well established business involving buying expensive things and leasing them to the companies that intend to operate them so they can sell services: aircraft leasing.
AER is the biggest player and they have a P/E ratio of, drumroll please, 6. And I expect that GPUs, despite currently looking like an appreciating asset, will actually depreciate faster than aircraft in the long run.
P/E is price to earning. Price to revenue is P/S. AER's P/S is like 3, so the discrepancy is much worse than you think.
Sidenote: 3 is actually high. 94 is absolutely ridiculous.
> Sidenote: 3 is actually high.
Do you mean low? AAPL has a ps of 10.
You're arguing with people who have no idea what they're talking about.
The question on my mind is-is this IPO designed to rip off recreational passive investors and those of us that invest in retirement accounts?
With the Nasdaq rule changes, almost certainly.
Those rule changes aren't happening.
Yeah, only a small portion of SpaceX's revenue actually comes from Space (payload delivery). At this point they are basically an ISP (Starlink) and a datacenter/leasing company.
It's not clear if Musk (SpaceX/X.ai) is really pursuing AI any more - I expect he hasn't necessarily given up on it, and he hasn't said he has, but it seems he's rented out almost all of his GPUs to Anthropic and Google, so that's not going to be much of a revenue generator, at least for time being.
The profit center, to the extent any division makes money, is Starlink, yes, but what we have always known as SpaceX is just a tiny side project in the combined company.
According to their IPO S-1 draft they are 93% an AI company and 4% a space company. Its the remaining 3% of the company that is profitable, the Starlink stuff.
Given the amount of compute rented I doubt there’s anything meaningful left for the people there to do any AI.
Comparing SpaceX to an aircraft leasing company seems more foolish to me than a 94x multiple.
I understand the gist here, but come on. This is a generational company. It’s the only relevant space launch business, and has its tentacles deep in AI infrastructure as well. Maybe the AI bet is foolish — I don’t know — you should short it!
I am comparing SpaceX’s datacenter-and-GPU leasing business to aircraft leasing.
It’s possible, and common, for one large company to have multiple business lines, each worthy of a very different P/E multiplier. In principle you end up with a weighted average of some sort.
edit: Matt Levine has some great articles about this phenomenon and how some companies try to juice it.
He can’t do with rockets what he says SpaceX has to do to meet its goals, and he isn’t raising enough money to get the job done either.
It’s another misdirection.
I would short xAI but the market can remain irrational longer than I can remain solvent. Plus all the foolishness to prop it up with other businesses just seems like bad accounting.
I don't think you can short it before the IPO happens. Well, unless you've got a few millions and go to a bank and have them make a product for you specifically. But for normal people, for now, not happening.
Brilliant meaning clever, like a well thought out scam.
Not brilliant meaning something actually positive for humanity in any respect at all.
> Truly a brilliant deal for everyone involved.
Except for people who have pensions/investments in whole market class investments who become exposed to an over valued company with a propped up value.
If whole market means whole market, then such investments are exposed to companies who are fairly valued, companies who are massively overvalued, and companies who are massively undervalued, and the whole range in between.
If you want to start picking and choosing which companies are overvalued and which are undervalued, don’t invest in whole market funds. But most people are not good at that!
the problem:
The Nasdaq 100 and FTSE Russell made a rule change that allows SpaceX to enter index without mormal time for price discovery. Most index funds have rebalance day just 5 days after IPO. S&P also made rule change for S&P Total Market Index and Dow Jones US Total Stock Market Index, but left SP500 intact.
Nothing wrong with SpaceX or Anthropic getting into indexes with fair rules, this rule change is pure creed+corruption.
Those funds are not whole market funds.
But there are things to say about your point too. I’ve commented on that in other threads.
I don't understand this logic. Does whole market mean scamming companies too?
Fun fact, both Enron and Lehman Brothers were in the S&P 500 when they went bankrupt. So yes, the whole market or even the market of the largest companies, includes some that may not be great companies. The beauty of the index is you don't have to know or care, since it'll take care of itself over time.
Yes. That’s what passive investing is. You give money to the passive fund, the passive fund buys the market. No regard to price or any other metric.
Also, there’s a long history of companies that people yell about being overvalued being the drivers of index returns, because one of the major drivers is growth rate, whereas retail investors tend to look mostly at current state.
The key there is "whole market." This is still a tiny sliver of the whole market and most people's exposure to it is minimal. Still a wealth extraction move ultimately, but like many other such moves, the few pull just a little from each of the many. Nobody individually goes broke, but the whole class gets slightly poorer. It takes a village to raise a billionaire!
Trillionaire
If you want to play “active investor” and pick and choose what companies you invest in, don’t be surprised when you underperform the whole market.
SpaceX could rise to be a major winner that makes people a lot of money. And then what? You missed out and underperform the whole market.
Alternatively you may want to be a passive investor using the current rules for index inclusion, rather than having them altered to favor this loss-making trashcan on fire.
OK, but SpaceX is not printing money out of thin air. And neither does the stock market. Somebody will be left holding the bag eventually.
> If SpaceX maintains this revenue multiplier
Yeah, if a ridiculous premise is given you'll reach a ridiculous result.
It's not that ridiculous considering these are the current facts on the ground.
> SpaceX is trading at a whopping 94x revenue. This deal increases SpaceX's revenue by $11 billion per year. If SpaceX maintains this revenue multiplier, then the single deal boosts SpaceX's valuation by 94 x 11 billion = $1 trillion dollars.
That final number doesn't make sense: if you're trading shares at $X revenue, increasing the revenue by $Y multiplier doesn't increase the share price by the same multiplier.
Sure it might not stay at 94x. But as long as SpaceX trades above 20x revenue, Google makes money from this deal.
And the bigger play is this deal pushes SpaceX over the finish line for S&P 500 inclusion. That's worth tens of billions for everyone involved.
I rreally dislike how big corp figured out that the can sell stuff to each other without actually moving some good. Looking at you, Nvidia... I have a feeling that the ordinary people will again pay for that.
This sounds exactly like the kind of thing that will be outlawed in thirty years after tracing back the root cause of the second great depression.
That would require regulators to actually pay attention, something they haven’t done actively since a long, long time
This is why it only gets changed after causing economic calamity.
First step would be to prevent the regulators from profiting to begin with.
In my experience, if we don't (meaningfully) root out corruption and ineptitude, we will continue to be governed+leveraged by one/both.
Outlaw what? Prevent companies from selling goods and services to each other?
The problem described isn't companies buying goods and services. It's buying from an entity they partially own and then profiting as that entity becomes more valuable because of the purchase.
it's not about that. it's about how it gets reported in their financials.
Yes, if it's done with an intent to defraud the general population, which could be the case here. Effects and intent really matter when deciding actions.
Except the regulators first outlawed what is generally considered to have caused the great depression (savings banks allowed to invest, which translates to very, very rich people being allowed to take massive risks with poor people's money) ... then re-legalized it.
So not only are the regulators not going to allow things that cause another great depression, they're allowing the things that caused the first great depression too. They must want a rerun.
(Because if you don't allow this you're effectively demanding the extremely rich make good investments to stay rich ... and not even France, otherwise pretty socialist, dares to go that far)
I think SpaceX should be valued on rockets n space n stuff, not how many magical calculator dollars they bring in.
Surely Google can "make compute go" for $1b/month. Nice way to avoid holding the bag, maybe?
The market seems to value both rockets and magical calculators.
I mean, we all understand that this is some sort of circular financial play, but at the end of the day Google is paying SpaceX $1 billion for compute. This is no different from AWS or Azure.
You're right. Share price isn't based purely on a multiplier of current revenue.
But they did need to shore up that p/e ratio. Got to assuage our inner Ben Graham.
> SpaceX is now GAAP profitable under the existing rules
We'll need to see audited financials, but if this part is true people are going to be upset. I wonder if all the people who have been acting like the S&P rules came down from the mountain with Moses will start lobbying to change them to keep SpaceX out?
And to be clear, I think SpaceX is way overvalued and I wouldn't buy it stand alone. But there are a lot of companies in the S&P 500 I wouldn't buy stand alone, yet I still own a a lot of an S&P 500 ETF. /shrug
SpaceX is valued at that revenue multiple because of its expected revenue growth rate.
This deal is part of that revenue growth. So the new revenue would be already partially or even fully priced-in.
Perhaps it reduces uncertainty around the growth rate, but expectations were already sky-high, as shown by the multiple!
As an ignoramus to these things.... there are only just so many Googles though. Having made a significant jump, are they really expected to continue that growth?
Google and friends continue to see increased demand for their wares. The bet is probably that SpaceX is one of the best-placed companies to deliver incremental compute. They've shown they can build data centers fast.
The bet is that demand for AI tokens will continue to grow exponentially. And that SpaceX will be able to deploy and rent out GPUs to serve those tokens faster than anyone else.
The wrinkle is that they are planning to deploy those GPUs in space. That’s what people are most skeptical about, I think!
Space data centers need years of time to design, build, and deploy, 5-10 at least, and that's after they solve their multiple very difficult or impossible problems. How will they cool them? There are just simple ideas like giant structures to radiate the heat away, but you say you need to put lots of mass in orbit?
Like fsd, will take decades to figure things out.
Well yes it will be hard, and hence maybe not economical, and that’s why many people are skeptical of the business case (myself included btw).
But satellite cooling already exists (Starlink v2 satellites dissipate heat at over a kilowatt I believe), so that’s why other people find it plausible.
They also need Starship at minimum, which is now a 10+ year old project still exploding regularly.
Starship is at minimum a 2030 project at this point.
And even producing the volume of chips needed for the type of growth space data centers would need to have to justify this would be another decade if construction started now on those fabs.
This is the first time I get to understand why it is important to have big companies as your early investors.

assuming google sells, the stock tanks, nobody wants to buy next year
is this masterful? more like a scam
Now with this incredible deal, SpaceX is now GAAP profitable under the existing rules, and they get to join the index next year without a rule change.
Didn't they also run up against a "minimum free float" rule?
I don’t think your math is correct. Profit is revenues minus expenses. Unless Google’s purchase of compute brings SpaceX’s revenues into profit territory (such that their total revenues exceed their expenses), SpaceX still won’t be profitable. This is accounting 101.
Google’s investment in SpaceX is completely orthogonal to the analysis. Equity investments aren’t revenue for the issuer. (Gains on sale would be revenue to the investor, in which case, this would be Google, not SpaceX.)
An equity interest in a company is a perpetual claim on future profits. Equity IS securitized profits.
Google's purchase sends cash to to SpaceX, which they report as revenue, and which they earn a profit from.
SpaceX cannot report Google’s investment as revenue on its balance sheet. Full stop. Equity investments are reported as shareholder equity. If you don’t believe me, ask your friendly neighborhood CPA—or, perhaps so you’ll earn a valuable lesson about confidently spreading bullshit about subjects in which you are clearly uneducated (or, best, superficially educated), try it yourself in a public company and go to jail.
You don’t know what you’re talking about and are way out of your lane. Stop now. In fact, you should retract your parent comment and apologize to the community for leading them astray.
Did you even try to ask even ChatGPT or Claude about this first?
So SpaceX is selling inference capacity. Who else is? What were the competing offers for Google and Anthropic?
For your math to make sense, Google would have to sell its stake this year
There may be more to it than buying compute but what you're saying does not make sense for Google. More likely Google wants a good relationship with SpaceX and possibly to buoy the stock, but it's a bad NPV trade
On the other hand, google does not lose all the money in that deal. Computation is still expensive.
So at most they lose like 200M each month. Peanut compares to the potentially gain of the IPO.
> this single deal boosts SpaceX's valuation by 94 x 11 billion = $1 trillion dollars
That's not how valuations work. Also, it is not unlikely that SpaceX's valuation drops post-IPO (tech was 6.65% in the most recent trading session) due to its very rich valuation and a long tenured investor based that is probably looking to get liquid.
Google is renting compute from SpaceX because they need GPUs and SpaceX owns a huge supply of them and has excess capacity bc no one uses Grok. Google has stated that this is a temporary arrangement while they continue to build out their own capacity.
Isn’t the revenue modifier a result and not the cause?
Would you really expect a company to increase proportionally in value when they increase their revenue?
They still need 10% float and 1 year of bake time, so the rules are still doing some work for us
why revenue that barely cover the estimated revenue (and depending on assets yet to be acquired) boost valuation? is everyone an idiot?
So masterful that a random guy on HN can see right through it.
Let’s just call it what it is. It’s just basic fraud. They created a very temporary revenue injection right around the time of the IPO to defraud investors as much as they possibly can. Some businesses do this kind of thing just before they die because…why not?
No it is not. You are conflating the colloquial definition of fraud, with the legal definition of fraud. Fraud has a defined meaning.
Utterly nauseating. Why would google help prop up this company and its figurehead? Maybe this is finally the straw that breaks the camel’s back for me and google.
It seems like Silicon Valley has decided on solidarity among tech billionaires and they're gonna take average Americans' wealth to keep themselves semi-relevant globally as China assumes global dominance. This is after insulting and demeaning the rest of the world, they plan to try to sell anemic services to other countries in whose politics they're also meddling. Circular agreements promising to purchase goods and services without the money in the bank, but you can show your promissory note to a guy with his own promissory note who then writes you a new promissory note based on your first one to take to another guy with his promissory notes, look at all the paper.
Except they’re paying $30b (the deal is signed for almost 3 years), there’s no reason to believe that SpaceX maintains revenue multiples and this deal creates a trillion in value, liquid cash is not the same as pre-IPO shares. And finally, the deal comes down to $11 per hour of h100 equivalent, which is pretty much within market which experiences a severe lack of supply.
Do you really think its honest to call this Financial Engineering over Fraud?
No. The definition of fraud is "lying for financial gain". This doesn't qualify.

AI is really a pioneering engineering field
Since the S-1 filing, xAI has taken over and is likely the largest share of revenue. I would estimate that ~95%+ of xAI revenue, and 100% of its profit, is from renting their datacenters.
This is a datacenter REIT bolted onto a social media company bolted onto launch business bolted onto a niche ISP. The expected price to sales is ~100x. The best datacenter REITs trade at ~10x and pay a dividend, which SpaceX does not. Meta trades at ~7x sales. Comcast is one of the best-run ISPs, and it pays a 5.5% dividend on a stock trading at < 1x sales.
To say SpaceX is overvalued is to even beginning to convey the magnitude of the situation. It's going to be very painful when the valuation normalizes.
TSLA has a forward PE of ~200x. That is probably the most logical comparison with SpaceX. Proof that the market can stay irrational for quite a long time.
It fills me with a bit of dread about the future of the market. I am 10 years out from retirement, have a bit over 1M sitting in that market, and I wonder if it will implode in the meantime. I am fairly committed to the "invest like a dead man" (i.e. index funds, no touch), but the world we live in today makes me have real doubts that the next few decades will look anything like the last few.
About 10 years out as well. I’ve concluded I just invest a very balanced set of index funds and bonds and GICs across a handful of institutions, and then invest in my home because even if the housing market collapses I get to enjoy my nice home.
Other than that I’m just not over investing for retirement and instead making sure the money is spent today on family growth and experience.
I eventually just got tired of everyone with an opinion on what doing it right looks like or how to predict the market.
Plenty of hedged equity funds out there. Trade some performance for peace of mind.
Circular financing at its finest. And Self-dealing between the hyperscalers, openai, and anthropic.
google invests in anthropic and spacex - and shows appreciated values as earnings. Then it turns around and rents tpus to anthropic to show it as revenues. The main buyers and sellers for all of this are the hyperscalers, openai and anthropic.
It is a game of musical chairs while the party is still on.
Do companies like Uber, Tesla, etc ever intend to pay dividends? If a stock never intends to pay dividends, the value of the stock is simply the price the next shumck is willing to pay.
The value of the stock is your share in the underlying business. Because underlying business changes over time (hopefully for the better) you are not simply hoping another shmuck pays you more, like with tulips, whose underlying value does not change with time. You own a portion of a concern that is improving its own fortunes.
Furthermore, dividends are approved by the board once per quarter or once per year. A dividend on a stock is not a contractual guarantee like it is on a bond. Therefore, it cannot be a basis of value.
With your logic, Berkshire Hathaway is a long-running greater-fool tulip bubble whose shares are only bidded up by finding more shmucks.
This makes no sense. Why doesn’t the “underlying value” of tulips change?
“Underlying value” is a meaningless word btw
That’s the story, but it’s bullshit. The underlying intrinsic value of a stock can only be materialized if the company liquidates and you receive a share of the sell off of its assets. How many publicly traded companies abruptly decide they’re tired of the business, stop in their tracks, and liquidate their assets? This only really happens if the company is acquired or if it goes bankrupt. Acquisition is the closest the story comes to truth, but it’s also just forced sale to a greater shmuck. If a company goes bankrupt, a tiny fraction of the current stock price would be realized into cash for common investors because of all the privileged investors and lenders ahead of them, not to mention that the actual value of capital assets etc probably doesn’t cover all the losses (the company’s going bankrupt after all). The value of the underlying capital assets are essentially never returned to the common investors, and the idea that you own a portion of them is in practical terms a lie.
Well, the value of the stock for people who essentially do not have any meaningful control of the business must essentially be tied to the expectation of some liquidity event down the line -- future cash flows. So this could come in the form of dividends, sale of the stock, bankruptcy proceedings, or a purchase of the business.
If I knew for certain (big if) that a business would never have a liquidity event and I couldn't transfer my ownership then it's dead capital for all intents and purposes and you could consider its value essentially $0, right?
But you can transfer your ownership.
Excellent question. They may not intend, today, to pay dividends. However, the same question could have been asked about the successful tech companies of the '00s. Companies don't like to start paying dividends until they are fairly certain of their future profit stream and therefore ability to continue paying (and increasing) the dividends in the future.
Apple, Oracle, Nvidia, Cisco, Alphabet, Meta, Salesforce, and Qualcomm all pay dividends now. It's not unreasonable to expect Uber and Tesla to pay in the future. However, the median time after IPO for similar companies to pay a dividend is close to 20 years. So we could expect Uber to perhaps wfstart paying sometime around 2039. Tesla...is Tesla so who knows?
Google renting infra from xAI, I did not see that coming. My understanding of what computers are doing, what companies are doing and what governments are doing seems to be getting worse day by day.
Financial shenanigans aside, xAI seems to be buying hardware at breakneck speed. So why not?
https://techcrunch.com/2026/05/20/musks-xai-is-being-sued-ov...
I thought elon hates demis
Demis? Democrats or something else?
Elon likes money and power.
Demis Hassabis - head of Google DeepMind.
> Google renting infra from xAI, I did not see that coming.
Actually that seems to be fairly logical? Hardware is what xAI has, and it's in great demand. So sell what makes you money. The real story here is that that xAI hardware is going to be running Gemini and not Grok. Which is to say: Grok basically failed as a frontier AI and they need to pivot to a business model which makes money.
Obviously not everything Musk did was wrong. xAI bought a ton of compute when it was possible to get it. But the product they were going to build with it failed and so now they're deciding to be a landlord.
This IPO is just insane. No way do you justify a $trillion+ valuation based on what amounts to a bunch of commoditized rent seeking endeavors. Datacenters are buildings and chips, and everyone can build those. Starlink is just an ISP with lots of competition at scale (they have the high bandwidth mobile market cornered, but that's a very small market!). Mars is at best a grift on public funding. Even satellite launch services are commoditized and competetive these days.
Could you please describe the other satellite launch services whose prices are competitive with SpaceX?
Keep in mind Google also rents GPUs via GCP, so they could be just reselling these to GCP customers?
Thing is though, Anthropic was really against the wall with lack of compute pre xAI deal. And tbh, Gemini reliability has been abysmal which probably points to real compute shortages.
And nearly _every_ major DC project is really up against it with massive delays, etc. Stargate UAE has been badly affected by the Iran conflict.
So maybe long term this isn't a great business, but _right now_ I'm not convinced it's all financial engineering. There is a enormous shortage of compute and xAI has a load of it _available now_.
> Which is to say: Grok basically failed as a frontier AI and they need to pivot to a business model which makes money.
They can just run Grok as a local AI inside Tesla cars. It's actually really efficient as a compute platform because the Tesla cars are in motion at highway speeds, which gives you lots of free airflow for shedding waste heat via the car radiator. Way more efficient than trying to run AI on space satellites.
Grok is just DOA. No need to beat a dead horse. Even Musk got that thus the reason why he is renting the stuff it planned for Grok.
Grok has plenty of "non-woke AI" cred which will make it a preferred choice for lots of government-side and politically sensitive workloads.
Anecdotally, Grok is mostly not that anti-woke. It is coasting off of its reputation from Elon's marketing. That said, it does have meaningfully fewer guardrails, which is a real benefit.
I am pretty sure the gov gets an uncensored /heretic version of the AI models instead of the nanny stuff we get so Grok really doesn’t have a “killer” feature. Even for multi model passes(I.e used purely as a contrarian gate) it’s not really that great due the high rate of hallucinations.
Nazi AI is bad actually, most governments will not want to be associated with it
What do you think the term woke actually means?
I think their point is less that it really means something and more that enough customers think it means something to provide economic opportunity
The only frontier lab to be selling the compute rather than inference seems to say more about this economic opportunity.
Something which is inconvenient to trumptys
lol, not sure if this is a joke, but Teslas do not have anything close to the necessary hardware to run grok locally.
Who’s going to be paying for the energy? People have been floating using the cars as compute for years and it just doesn’t make any financial sense for anyone.
Teslas spend a tiny percentage of their life at highway speeds, and a major selling point of the platform is that their compute would be used to pilot the vehicle.
If they could train using Teslas they wouldn't have needed Dojo.
Xai seems pointless, and they've got gpus needing to be used for something.
You make it sound like they’ve given up on Grok, which I don’t think is accurate. I think it’s been mentioned the Grok 5 1.5T model is currently training on Colossus 2. And their recent deal with cursor is part of being able to eventually compete with Anthropic for agentic coding.
Strongly agree with all of this, except that charging rent for the use of an asset you own is not what economic "rent-seeking" means. I blame the dumbass economists who named it this, forever polluting the discussion to be had about regulatory capture and legalized political bribery.
They're struggling.
The future needs more AI compute. No one has enough AI compute.
Memory chip vendors are betting hard on this being a temporary state of affairs that doesn't last, and doesn't warrant commissioning a shitton of new memory foundries.
Musk is betting hard on this staying that way, and is putting the next Colossus into the last place not corrupted by NIMBYs... SPACE!
You guys don't understand. Banks like JPMC will make billions on this IPO. Doing everything to prop it
Maybe that was the handshake deal from twitter financing, twitter exit and so on. "I will make you whole".
I do not know, but I wonder if someone can tally the bankers from twitter buy, twitter merge into xAI and the new spaceX launch.
A huge chunk of SoaceX value in their filing is attributed to their AI technology (aka Grok). I believe it’s 90% or more… Now, it seems they’re leasing the infrastructure required for Grok to scale to Anthropic and Google. I wonder how that math works…
But what is xAI? I thought that was the company that had the compute + Grok, the AI company? Since when does SpaceX (which I thought was a space company?) own AI-compute hardware and/or can do model hosting? Are all of Musks companies just one big thing now where the names no longer matter, or how is it supposed to work?
Edit: seems I'm just a bit behind: "xAI — now part of SpaceX ", seems really strange for a space company to buy an AI company, but I guess rather that, than the other way around.
I think some justify it as SpaceX plans to offer hosting in space, and then use Starlink to distribute it.
Context here (Patrick Boyle):
https://youtu.be/IHD8BDFYyGI?is=dnpBeOoxH7LUJknm
Musk sold Twitter into xAI which he then sold into SpaceX as a financial engineering effort to lessen the impact of massive debts and cash burn. The IPO and some clever structuring is the final step in the process.
Next up Tesla and SpaceX are going to merge and that will another round of synergies where Tesla and Vision AI (in FSD) and xAI.
Not really strange... if the goal is to go to mars, you probably need robots, those need intelligence -> ai. It fits pretty well, especially because you want to own all the core technologies as a company.
Wow…sounds like some kindergarten stuff
Why 4-5 companies instead of one then? I thought the goal of SpaceX was to get to Mars, why does xAI need to have that same goal? Or he didn't think xAI was suitable for that goal, then changed his mind so merged the companies?
You are overthinking this. The whole purpose of the SpaceX / xAI merger is for Musk to launder his failing companies to make them more palatable to the public. Not unlike the complex Mortgage Backed Securities of the GFC era which had a ton of low quality debt but yet were somehow assigned spotless credit ratings. Twitter is also being rolled up into SpaceX for the same reason.
I sure wish my company were failing the same way Musk’s allegedly are.
Personally I can go without owing money to Saudi royals.
The stated goal is to "go to mars", the real goal is to make money.
He sold his failing but hype business to his soon-to-IPO successful but kinda boring business.
It's a way of laundering the debt and dumping into investors as he pitted different indexes against each other to force his way into one of them, and have people's 401k buy into them. Its a ton of money.
I wouldn't be surprised if Tesla is bought into spaceX in the future.
He’s a drug addict and sociopath. Also has very thin skin (and hair) so he does stupid shit. Somehow we are all left holding the bag on his BS.
It has nothing to do with Grok, at least not the current iteration. SpaceX is the only company that can concievably launch large scale orbital compute.
I’m out of the loop, why is compute better /after/ being launched into space? Is the idea just to be co-located within the ISP to reduce round trip time to the LLMs?
> $920 million per month from October 2026 through June 2029 for access to “approximately 110,000 NVIDIA GPUs, CPUs, memory, and other related components.
That's about $8,400/month per "component" is that in the ballpark at all with what a month of dedicated/exclusive access to an NVIDIA GPU would go for?
Makes a lot of sense that Musk should do the parts of the AI stack that look more like manufacturing/regulatory bottlenecks, and rent out the compute to research-focused AI labs. Does anyone know the full accounting of how much it cost to build Colossus (plus ongoing opex) vs. the revenue it's generating now?
Is there any data on whether Google, Amazon, Microsoft, Anthropic, OpenAI etc are most cost efficient in getting datacenter compute online and operating it?
I'd be interested in how large the range is here across company and region and specific data center and how it relates to companies like Hetzner if at all.
Well, Elon seems to take the fastest path possible to these DCs. One can envision a future where these get shut down for the severity of the pollution, not to mention being built and operated illegally [0].
[0] https://www.selc.org/news/xai-built-an-illegal-power-plant-t...
Which is precisely why there has been a push to weaken the EPA and other regulating agencies
> Is there any data on whether Google, Amazon, Microsoft, Anthropic, OpenAI etc are most cost efficient in getting datacenter compute online and operating it?
Well considering that ~80% of the price is hardware deprecation, I don't know why they'd be considerably worse than anyone else at negotiating hardware deals.
Typically when you buy in bulk, you have more sway.
Companies like Google also have in-house chips like TPUs that are substantially cheaper for inference for them to make than anyone else can get through Nvidia.
I’ve seen some numbers related to datacenters in Ireland and they would stress price per MW as a way to see where to build them. But then you have depreciation of equipment as well. Depreciation can be played with when filing taxes though.
I don't think they are most efficient for small GPUs. I think they might only be the one which have capex and certainty required for multimillion dollar purchase of GB200 NVL72 or something of that scale.
that's asking the cart before the horse; is there any data on what compute actually results in real GDP improvements?
Nothing other than vendor promises and white papers.
SpaceX valuation and ultimate success depends on two things:
1. AI demand continues to grow. 2. SpaceX's orbital data centers are profitable.
If both of those are true, then their current valuation is absolutely justified. I'm confident #1 will happen.
#2 is the big bet, and IMHO this is just an engineering/execution problem. All they need is (a) Starship to work reliably, and (b) a manufacturing line that can build a data center satellite at low cost.[1]
(a) is the harder of the two, IMHO, but they are well on their way. Once they successfully recover and refly a Starship upper-stage, they will iterate step-by-step until launch costs drop to the level they need.
Now assume that SpaceX succeeds. What if AI demand continues to grow and SpaceX orbital data centers are profitable? Think of their moat: they spent 10 years and billions of dollars developing a fully reusable rocket that happens to also be the largest rocket in the world, and that costs 1/10th of what other rockets cost (per kilo to orbit). Plus, they have an assembly line that can build data center satellites cheaply, and they start fabbing their own AI chips.
How is anyone going to compete with that? There are a bunch of data-center-in-space startups, but none have their own rocket--they're going to have to pay SpaceX to launch them. Blue Origin is developing a rocket as large as Starship, but it's not fully reusable--they will never get the cost down to Starship levels.
What's interesting is that all the AI companies, OpenAI, Anthropic, and even Microsoft and Google, are mostly leasing their data centers from someone else. They think compute is a commodity and the value is the trained model. But if SpaceX has the cheapest data center with the most capacity, they will be able to extract profits from the AI companies or (why not) compete against them with their own model (Grok).
In 10 years we'll see whether SpaceX succeeds or fails. If they fail at this, they will retrench back to a launch company (assuming they are still in business). But if they succeed, they will be a massive company, and the synergy between their businesses will be so obvious that everyone will say, "of course they succeeded!"
----------------
[1] Don't be distracted by claims that "cooling in space is hard" or "radiation is a deal-breaker". Neither of those are insurmountable problems--they are just engineering problems. Crucially, they are problems that are easily solved by getting mass to space. If you can get mass to space cheap enough, those two problems are trivial to solve.
380 dollars per second... Good to know I could afford my own data center for an appreciable fraction of a minute.
Why would you want to own your own giant datacenter? What would you do with it? Of course it's expensive to operate a datacenter that serves millions of people.
They were just being jocular.
plus $473 per second from Anthropic
> As part of that deal, Anthropic agreed to pay SpaceX $1.25 billion per month through 2029 to rent all the available compute from its Colossus 1 data center near Memphis, Tennessee, that xAI — now part of SpaceX — originally built for its own artificial intelligence efforts.
I don't get why SpaceX is going public. But anyway, well played, the whole crypto mining that dried out GPUs back in the day seems tiny now.
> I don't get why SpaceX is going public.
Liquidity for investors. They raised everything they could from private markets, government contract, debt, the remaining source of financing is from the public
For context, Alphabet earns ~$12k/sec.
These deals are part of how the AI economy operates. Amodei has explained this in his recent Patel podcast.
1. Building datacenters takes time. Months, if not years. They take billions of investment.
2. AI revenue is highly unpredictable. Sure, you can make predictions, but maybe your competitor releases a better model 2 weeks after your release, maybe the new model you built isn't as much better, maybe the chinese models steal your show, etc.
3. AI revenue grows a lot. Anthropic's case is 10x per year.
4. So if you are off by just a year in terms of how much GPU you actually need, then that means a 90% of your compute capacity is wasted, and you go bankrupt.
As a solution, companies buy compute from each other! If one company's model did well, they can buy compute from the company whose model didn't do well (like in the case of grok). It's beneficial for both sides, so positive sum game. So deals like this aren't something bad in itself.
It's nothing new either. In SAAS deals, you often commit to a certain revenue and then pay extra if your revenue exceeds that amount. And power market is cut in two as well: longer term deals plus spot markets. Spot prices are way higher than the longer term deal prices.
Given it's SpaceX of course there is financial engineering involved: the GPUs aren't actually owned by SpaceX but a daughter company, and it's been financed via loans that are backed by pension funds. So it's already the case that pension funds back bear the risks associated with SpaceX's operations.
Right now, the bulk of the AI bubble sits in such debt statements and not in public markets.
“If we fail to deliver access to the committed amount of GPUs by September 30, 2026, then following a one-month grace period, Google may immediately terminate the agreement or accept the number of GPUs provided, with a corresponding pro rata reduction in the monthly fees. After December 31, 2026, the agreement may be terminated by either party upon 90 days' notice.”
https://www.sec.gov/Archives/edgar/data/1181412/000162828026...
It’s only to boost the IPO price. The agreement will last only a few months on paper. I doubt it is a real transaction.
Either that or SpaceX is permanently turning xAI's assets into a neocloud because xAI itself has no traction.
The whole thing looks rather desperate. I wonder what SpaceX's margins are on these contracts.
SpaceX has recently started pitching itself as an orbital datacenter company.
If you buy into that business model (or pretend to), it makes sense for SpaceX to start selling compute early. Their "earthside compute" clients of today are "skyside compute" clients of tomorrow.
A part of Musk's old pitch for Starlink was: space-based solar makes perfect sense for powering space assets, and no sense whatsoever for powering Earth assets. So you have to find a way to use that power in space to do something economically useful. Comms were the only scalable way to do that, so Starlink it was.
I can see how space-based datacenters would follow the same logic. If SpaceX can make them economical, that is. There's no guarantees of that - but if anyone at all can make space-based datacenters economical, it's SpaceX.
> if anyone at all can make space-based datacenters economical, it's SpaceX
Let's hope burning ten thousand tons of toxic e-waste annually in upper atmoshphere never becomes economical. Or mankind gets to senses and bans externalizing your e-waste problem by burning in atmosphere...
> ...burning ten thousand tons of toxic e-waste annually...
Expressing water usage in gallons makes it seem really large, too. NASA says[0]:
If we assume that they're all the heavier v2 units, the total mass of the orbital portion of Starlink is ten point four tons. [1] If we assumed that they lasted one year (instead of the five that they're reported to last[1]), then over the course of a year, Starlink would dump six hours worth of asteroid collisions into the atmosphere.I think we'll be fine. Pour all that frustrated energy you have into substantially reducing the amount of incredibly hazardous d-waste [3] big commercial operators burn up into our atmosphere, instead.
[0] <https://science.nasa.gov/solar-system/meteors-meteorites/#h-...>
[1] According to [2] there are currently 10,413 satellites. At an assumed 1760 lbs each, this works out to roughly 10.4 tons.
[2] <https://www.space.com/spacex-starlink-satellites.html>
[3] "dino"-waste, AKA CO2
I think you missed a factor of 1000 somewhere in there: Each satellite weighs about 1 ton, there are about 10,000 of them. That is 10,000 tons in orbit for the constellation, not 10. Assuming a 5 year decay, that's 10000/5/365 ~= 5 tons / day. Still about 10% of the natural incoming material, but considerably more than your "six hours worth per year".
Why would it ever be more economical to put datacenters in orbit, rather than on some dirt cheap land?
There are no NIMBYs in space. No government permitting on land use. And solar power is plentiful. It's like having a dollar store Dyson sphere.
Making use of that is predicated entirely on being able to put a lot of hardware into space cheaply. SpaceX is the undisputed best at that, no one comes close. The question is whether their "best" is good enough to make space datacenters economical.
There are many Not In My Orbit people on this very page. Many current national politicians would be happy to vote AI out of orbit today. Space is not an escape from earthly politics.
But you don't have to build it in someone's _backyard_, just build it in a middle of nowhere.
I am surprised how many people say that there is no reason to put data centers in orbit, when, at the same time, data centers are becoming the hated thing du jour all over the US and politicians left and right (but mostly left-of-center) are touting bans and restrictions to their electorates.
It is definitely to escape most political pressures on Earth. They will never be able to sidestep the US feds, but aside from an open war with China or Russia, all other authorities are out of the game when it comes to space.
Because dirt cheap land usually does not have dirt, cheap water or dirt cheap electricity.
Water in orbit: famously cheap.
Ah yes: computation. Famous for annihilating water. Every bit you flip consumes an H2O molecule.
My job is mostly worrying about cooling paths, maintenance, power, heat transfer, lifetime of GPUs, and high performance networks. NVIDIA partner. I can drive to the datacenter. This stuff BARELY works here on Earth. Especially thermal issues.
Looking forward to watching spacex defeat physics.
Well, how do you cool servers in space then?
Evaporative cooling is the way it happens down on earth - and that shuttles h2o molecules from dense useful clumps like aquifers and rivers to a less useful form spread out in the air. But evaporating h2o isn’t an option in space afaik - since there’s a shortage of air to take up the h2o. In fact I think radiative cooling is the only actual option in space.
That's the neat thing: you don't, or at least not in the megawatt range. A kilowatt can be done with radiative cooling but doesn't get you far with a hypothetical datacenter satellite.
So, somehow the servers can run hot in space without a problem?
No; if you try to do this you don't launch in the first place because the amount of servers required to be useful can't be cooled within your payload budget.
That won’t ever be the case. It’s pure grift. There is literally no other actual reason
The data link between earth and space has so much bandwidth.
There are sensors in space that send data to earth it gets processed and then the data is sent back to space then to the end user back on earth. If you do the compute in space you save the space-earth transfer time twice. Latency and availability of bandwidth are both factors.
There may be limited utility for this outside of military.
Space-based datacenters simply won't work. That people are talking about them shows Musk is the greatest snake oil salesman the world has ever seen.
> Space-based datacenters simply won't work.
Everybody knows.
Musk is a snake oil salesman (that’s been clear since the self-driving car promises) but he also has made a lot of people a lot of money and that’s all anybody really cares about.
None of his companies have a traditionally reasonable valuation. Is there any reason to think that’s going to change soon?
Can anyone explain how the thermals will work? One of the biggest challenges on Earth is cooling the data center, and it's at least as challenging in space.
It won’t. It’s not supposed to work, it’s a mirage to raise dumb money. It’s way, way more challenging to cool something a vacuum. The only option is radiative cooling, which is far from being performant. The idea is as realistic as Musk previous grifts such as his digging company and there hyperloop, both absurd and supposed to revolutionize transport, both created as grifting devices and ensure public transport doesn’t develop in the US
The earthbound equivalent would be strapping each chassis to the back of a dedicated solar panel and having the panel double as a giant heat sink. The problem is that doesn't work on the surface due to (at least) rain, the day/night cycle, and the cost of real estate.
Isn't a solar panel going to be a poor heatsink, though? It's flat, and thus has relatively small surface area compared to its size.
In atmosphere, yeah, relatively speaking.
But it doesn't matter since in this scenario each chassis is powered exclusively by the respective panel. How hot does a black panel sitting in the midday sun get? That's your equilibrium temperature. As long as it's within the operational limit of the device there's no problem.
The reason earthbound DCs are difficult to cool is because of density. When you match up panels to devices and shelter in their shadow you no longer have anywhere near the same power density.
Thermals are one among many really big challenges that require costly solutions.
> won’t work
A datacenter (earthbound or space) itself is a fantastical idea until a mix of events and inventions made it feasible to build them to sell compute.
You think the military can’t or won’t dump billions into this to make killing people with drones more effective?
It’s a engineering challenge not impossible.
There are asteroids with concentrations of precious metals more valuable than earth's entire economy. Why don't we just send up spaceships to mine them and send the haul back to earth? What country would say no to free money?
After all, it's just an engineering challenge, not impossible.
The numbers on that are at least somewhat questionable. Even ignoring that you'd crash the market (thus it's not actually worth what it first appears to be) what is the total fuel cost to adjust the orbit of the target asteroid to land the entire thing back on the earth? Because that's what you're doing bit by bit as you shuttle loads of ore back.
Now if you have space based manufacturing or fuel production on the other hand ...
When I hear space I think "that's the perfect location for a data center", since data centers are lightweight, small, require little power, don't need human intervention, have lifetimes measured in decades and don't have to reject heat. Since space easily satisfies these requirements, space is an ideal deployment location for data centers.
Yeah... What am I missing? Like why isn't this just laughed at when it's proposed?
I felt the same way about the "tube with an air hockey table in it." But here I am fifteen years later eating crow as I take the hyperloop to Vegas.
Isn't the Vegas Loop just a car tunnel? As far as I know, there aren't any actual hyperloops[1] involved, just a narrow highway, even if they deceivingly brand it "Loop".
https://en.wikipedia.org/wiki/Hyperloop
That’s the joke
It seems off at first glance but actually appears to work out if you do the math. You can model a solar panel as a flat, opaque rectangle. You can calculate power generation and equilibrium temperature for it based on surface area. If you require additional radiative surface area to achieve the desired equilibrium temperature you can place a flat triangle orthogonal to and behind the solar panel in its shadow.
Compute is "free" at that point because waste heat is coming out of the total energy flux which was already accounted for (because we modeled it as opaque).
Of course swapping out the equipment poses a bit of a challenge. The "helping hands" rate is entirely unaffordable and wait until you see this new DC's physical access policies. 0/10 would not rack with them again.
This may be one of the rare instances where the sarcasm is obvious without using the sarcasm font
> I wonder what SpaceX's margins are on these contracts.
In the Anthropic deal they have to be negative; Anthropic's announced higher margins during the deal.
This is all just the typical Elon hate. What's desperate about getting paid $920,000,000 per month? If that's desperation, I'd love to start groveling more!
Given extreme supply constraints, it's very unlikely that Google or Anthropic will just suddenly cancel right after the IPO unless their own demand collapses. And even if this were true, what value would that provide Musk? Could you imagine if your newly public company suddenly received termination notices from your two largest compute customers? Disaster.
Try logic.
I have no love or hate for Elon Musk. I wish him luck with his space endeavours.
What's desperate is announcing a temporary (allegedly) doubling of revenues days before an IPO that has been criticised for being overpriced at 93 times sales.
These data centers were supposed to serve xAI. Now suddenly they get rented out to others. Why the sudden change of plans?
It's either an emergency accounting gimmick or the effective shutdown or repurposing of xAI.
It’s a repurposing of xAI to be a commodity service provider during a crunch for that commodity. It would be dumb if xAI had any quality or market traction, but they have neither, so it’s actually a rational fallback. But it writes off any high margin future in favor of low margin scale.
And once the compute crunch is over, they’ll have a lot of overprovisioned data centers with no business to soak up the capacity.
Why don’t you have hate for Elon? You can love his companies but hate the man. It’s what I’m doing anyway.
Didn't Anthropic pull the same in both ways? you pull me up I pull you up kind of deal? Sounds like SpaceX bought themselves some time up to Q4, which is not the case of Anthropic and even worse for OpenAI. Not counting that none of them got their S&P500 fast-track ticket.
why would Google help a competitor like that, though?
Google (Alphabet) owns 6% of SpaceX which they bought for $12B in 2015. They want to maximize the value of their investment.
Google is safeguarding it's investment in SpaceX.
The article mentions Google is heavily invested in it.
How is Google competing with SpaceX?
If you look at the IPO filings you’ll see that Spacex as we know it is just a small part of the expected revenue generator. It is supposedly Grok and AI, hence Google competitor.
I can’t believe serious people use Grok. It has to be propped up by Twitter usage/Musk fans right? It really strikes me as the worst one.
They’re both AI companies
All companies are now AI companies. Just like a while ago all companies were suddenly Ads companies. The entire tech sector is one big FOMO - once you reach certain scale you do exactly the same thing as everyone else.
I get what you mean but SpaceX owns xAI, which is objectively a company that trains models and has massive distribution by owning X.
I don’t think their models are competitive with Google, and Google obviously has the best distribution imaginable, but they definitely are a competitor.
In the way that Michael Jordan and myself are both basketball players
I'd push back slightly — not on the conclusion, but on the reasoning. There's a simpler explanation that accounts for the same observations.
is there a reason you didn’t give the explanation…?
One of which has more capacity and wants even more, one of which has less capacity and is renting it out.
One is an ad company the other a lifestyle venture?
In the sense that if you want to sell anything whatsoever today it must an AI story.
Maybe common investors want to sell stocks to retail
They are not. The amount of conspiracy in high ranked HN comments for AI companies is insane.
Feels like these IPOs are thankfully the top coming before the AI crash and we get back to the real world.
One can hope, but that sentiment is quite unpopular on HN.
Everything is a conspiracy now.
Of course this is a real deal. Compute is the most valuable resource in the world for these companies at the moment.
What exactly is SpaceX's core business?
Their satellite internet business is the only thing which makes them money, which is enabled by their orbital launch business which is as of right now not profitable and I have no idea of if it ever will be but without it they would not be able to launch enough satellites.
Their stupidity with AI and buying X mostly seems to be about scamming investors to make Musk even richer. Like this particular deal is just them doing what CoreWeave does at a SpaceX valuation.
Launch isn't profitable simply because ongoing Starship R&D is eating into it. A lot of opex, capex, and pre-revenue.
If they start running Starship anywhere near the way they do Falcon 9, it'll flip into profits. A lot of big bets SpaceX made ride on Starship coming online. I'm honestly surprised Starlink is already so profitable without it.
One of their big named bets includes: orbital datacenters. Which puts this specific deal into perspective.
80% of the space launch business is putting starlink satellites into orbit, so it's all internal funny money. They could very well be letting the space launch business take losses to make the satellite internet business look better (only profitable part of the whole thing).
Wasn't starship supposed to be funded by the NASA contract?
Orbital datacenters sound like a dangerous bet. I couldn't think of a worse place for a lot of delecate electronics.
Have you considered Magma Chamber datacenters?
Boomers and luddites won't let them be built on earth so no other option really
It's more unpopular than that. Not surprising since they're competing underhandedly for electricity generation with everyone else.
I can understand this being a move to increase valuation, but I can't connect with the stupidity and scamming investors argument.
Sorry, I was unclear. With that I did not talk about this particular deal. This particular deal seems sane. XAI built more compute that they can use themselves since Grok is not very successful so to not just have the hardware standing there they rent it out to competitors. Makes total sense.
It is other things Musk has gone with Twitter and SpaceX which are shady.
I'm pretty sure xAI is just Musk throwing a tantrum after being played for a fool by Lying Sam.
Smoking crack and investment fraud.
With a light sprinkling of space.
Harvesting energy from the convulsions of people who got tds / tiktok psychosis during covid
Its main business is connectivity. Starlink generated over 10B last year.
Becoming a broader infrastructure company with xAI.
That's only about 35% more than the main telecom operator here in Belgium (Proximus: $7.2B revenue in 2025, $2.5B market cap, positive earnings for 15+ years).
Obviously Starlink can and will growth. I'm just pointing out how insane the market cap is, when compared to similar scale "connectivity" businesses.
I'm with you the 5B loss for 18B overall revenue shouldn't grant a valuation anywhere near 1.7 trillion.
was just answering the question.
> Starlink generated over 10B last year
An entire one-hundredth of their proposed valuation!
Yeah, crazy for a company with nothing but the largest civilian satellite network and what amounts to a monopoly on space flight.
Profitability of space flight has a hard maximum. It’s not anywhere close to what their valuation would suggest.
There’s a reason Elon keeps trying to get investors to believe his “data centers in space” lunacy, because you need that sort of magic pixie dust to justify why any of this valuation makes sense, let alone have anywhere to go but down.
Starlink terminals are popular, they put them on drones to avoid jamming (Starling jamming exists but not that easy for now). It might be their sales are inflated due to its use at war.
Government contracts. Dumping its shares on retail investors. Selling compute to AI vendors
A datacenter that also provides connectivity/Internet
Elon Musk.
How can SpaceX have so much GPU spare capacity? It doesn't make any sense.
Did Musk blindly order humongous amounts of GPUs years ago before any of us had any sense of the scale this was going to reach?
They acquired xAI
Is this admission that google’s proprietary chips etc. are not cutting it? Why would you need a bunch of nvidia GPUs if you have your own silicon? (AFAIK they have their own for both inference and training do they not?)
How do you come to this conclusion? All it means is that spacex has compute and google does not.
Suppose tpus were theoretically a million times better, but cannot be produced due to supply chain constraints, this action would still be rational.
My personal take is that this really shows how bottlenecked the entire supply chain is. For such an important commodity there are shockingly few players ready for scale.
I see it mean two things:
1. Indeed, Google is compute-constrained, and is ready to buy any it can.
2. xAI (now SpaceXAI) has a lot of idle compute, which it resells to Cursor, Anthropic, Google, probably others as we speak.
In other words: Google is training models, xAI is not.
It's a very long contract (till 2029) for just covering themselves for supply.
3 years is quite a short horizon when it comes to semiconductor fabs. Also this article is a dupe, when it was previously discussed it surfaced that after some time either party can cancel with only 90 days notice.
No its not.
"Both SpaceX and Google have the option to terminate the agreement with 90 days’ notice after December 31, 2026"
Kinda; while it does show that overall Google's proprietary chips etc. are not cutting it, it doesn't say if the problem is the hardware itself or the factories to make more of the hardware. Without more information, it could be that Google's hardware is 100x the energy efficiency per token, but they can only make enough hardware for 1% of the tokens there's currently demand for: 1% of your product being 0.01% of your costs isn't nothing, but it leaves the other 99% at full price.
Supply and demand? Bubblists seem to think there's an infinite supply of chips, power, and water to make as many chat bots as possible; physics, as usual, dictates limits.
Not necessarily, just that they don't have as many as they can make use of, and that xAI can't make more valuable use of them than renting them out.
Yes, it is issue of scale, google had to restrict usage because hardware are not available, regardless of what kind of hardware that is
Or it’s paying to make sure competition can’t buy said compute. Also isn’t Google an investor in SpaceX anyways?
At this point you are not buying a particular chip. You are buying whatever compute you can get.
It could be, or simply we are so far away into chip shortage that even google needs to buy from other people’s pot.
Its because none of the promised Data Center and NVIDIA hardware deployments described in NVDA earnings calls have actually happened. Once more Ed Zitron has the goods: https://youtu.be/zbKDmkJPVvI?t=482
Or alternatively there is simply a huge demand for compute and this is helping them fill a short-term need. Keep in mind if you saw in the article there is a 90-day cancellation clause. This is a nothing burger.
> 90-day cancellation clause
In other words, this is a fake IPO booster
I don't think so. It provides some nice optionality for Google and I am guessing this opportunity only exists because Grok is not popular and xAI does not really have any other use atm.
"It will have to be paid for," they said. "It isn't natural, and trouble will come of it!"
Fellowship of the Ring.
I'm curious if this offer lasts until after the IPO.
When as appears inevitable Google decides to stop using this capability what will it do to the SpaceX stock value?
So Google AI will now be running partly on xAI data centers which run primarily on natural gas burned on site next to poor neighborhoods in Tennessee and Mississippi causing massive air pollution to these families and children. Is anyone else disgusted by this? I’m imagining all the people there developing lung and other issues because of this. Greed and power on full display over doing the right thing.
I’ll be switching off the Gemini model at work (Composer’s been off since their xAI deal). This is the final straw for me to move completely off Google services.
I knew GCP was third banana but what is even happening?
Because SpaceX has excess capacity.
If you can't buy DRAM, you gotta rent your compute infrastructure.
$$ taking another circular financing lap.
It's all about the money.
This feels actually like a pretty safe bet for Google, they secure the compute in case it works (I doubt that the described volume will be available in the near future), while if SpaceX doesn’t manage to provide there is not much loss. I see it more as another way of blowing up SpaceX valuation on paper…
Sorry, what?
Does this mean that SpaceX are the only company that really did build some datacenters to put all the million of GPU/TPU/whatever they all talk about everyday?
I mean, Google, Amazon, Meta and Microsoft told investors they spent more than $1B per day last year in CapEx... why on Earth do they (well, Google and Anthropic at least) need to rent compute to SpaceX, of all companies?
They overbuilt capacity for grok but no one wants to use grok for several reasons
Scarcity. It's becoming difficult to plan for new data centers. They will rent where capacity is available. Grok hasn't gain the expected popularity.
Other companies built data centers but also built products that soak up their data center capacity.
xAI built data centers, and products that are mostly good for nonconsensual porn and confirming a small group’s biases. So they have a lot of excess capacity, and might as well rent it to the adults.
No, CoreWeave for example also rent compute to the big AI companies. This likely just means Grok has few users so they need to rent their extra capacity to their competitors.
Plus it’s not like some absolutely enormous data centers, only 300MW.
Yes but someone will be along shortly to defuse what sounds like giving the bad mars man credit where it’s due. Like everything else he does that works out, it was just luck, timing, actually a mistake that worked out, or someone else behind the scenes that he got lucky in hiring at the right time (by accident).
People with access to enormous wealth tend to get a lot of chances at the betting table.
If he’s so smart why isn’t grok using all that capacity?
Building excess capacity from the start and selling it for a billion a month to constrained competitors. I only wish I could be so dumb.
Short memory. When musk was buying all of this capacity it was billed as xai is going to take over the world. Instead grok is a flop and now he has extra capacity. If xai was a data center he’d be smart. But it is a failed Ai venture.
It’s like training your dog not to jump on the sofa. But then you fail to train to stay off and then brag about how you trained it to stay ON the sofa.
Source: vibes
If your dad had owned an emerald mine I am sure you could also have been that dumb.
But to be more serious: It is impossible to say if this is good or bad for XAI without more numbers. What if they bought their compute way over market price and sell it at a loss?
Cloud companies were made to sell others compute. Now, one is buying billions of compute from SpaceX, a rocket company. That sounds so backwards lol.
Great work by Musk and his companies to be in a position to sell billions to cloud vendors. I'd have probably missed that opportunity while trying to build great rockets or AI models.
