The cynical viewpoint is that this is Elon capitalizing on current datacenter hype to inflate SpaceX's valuation based on theoretically overcoming tremendous amounts of hard physics problems, over the next 5-10 years. As he did with FSD, Boring Company / Hyperloop, Twitter, etc.
So far, Tesla has been a blockchain, energy, robotics, and now a compute company.
Musk made some bad bets, but also some good ones (Falcon rockets, Starlink) and some at least promising ones (Starship, Neuralink). And Twitter bought him enormous political influence - I wouldn't consider this a failure either, from the realistically-cynical point of view. That cannot be measured by revenue alone.
Musk has been coasting on his successes from 10+ years ago. He has nothing good to offer anyone in 2026.
Would any VC(one without a conflict of interest) invest now, for the long term, based on those visions?
Like, sure, but also, that seems like a lot of work, a lot of extra cost, and a lot of risk, all just to avoid building it in Kansas.
Orbital compute is technically very feasible. We’re not talking about a datacenter-sized structure, but a lot of rack-sized satellites connected by laser links. SpaceX has gotten pretty good at building, launching, and managing large constellations.
Economically it obviously it has challenges, but there are some advantages (6x solar production, free real estate, less regulation, arguably simpler cooling) to balance the extra costs (launch, radiators, lack of access for maintenance, limited lifespan, etc).
I don't actually think this would be hard to imagine. I've been a huge fan of Space X since it's launch exactly because these types of things do seem feasible because they save so much of money if they are achievable.
A moon base with a secondary launch site, yes. Mining asteroids for precious metals, definitely. I'm not some Luddite.
My only point here is that you can build a data center on the ground trivially easily. Any data center that can exist in space could much more easily exist on the ground... where you can update it and fix things that go wrong. The only issue is politics. I'm entirely happy to be wrong here. If someone can explain the thesis, I'd be happy to get on board.
I've heard this often. It's not what happens. More correct to say that engineers (not Musk) got a booster to land in a pre-specified spot. The "chopsticks" aren't waving around to catch anything flying by. The booster comes to them.
You aren't even being roped into it with taxes, nor do you have to buy a single share. Other than willingly reading about it on whichever news sources you choose, your observed life will not change a single bit.
You can choose to seek out that info, or you can remain blissfully ignorant. But please don't join the online cacophony of people polluting the threads thinking everyone wants to understand just how ignorant they are.
I get it, I really do. It's a hard task and you don't understand it. But WHY do you feel the need to share that you don't understand? Do you think it makes you look smarter? Do you feel like you fit in more now? If you seek to understand, why aren't you asking questions??
It's a ridiculous idea, and I don't believe it's what they are really pursuing.
A less good business for the data center company.
Why?
If you're curious, I explained why space data centers are such an irredeemably stupid idea in my eyes a few comments up.
There's even more rewards for putting a million people on Mars and reaching a market cap of 7.5T by a certain date. Oh yeah he has to stay employed too.

Oooor, try this one on for size:
What if they're not out to cause offense and the malice you impute is just an illusion under which you yourself are laboring alone? What if it was a well understood and not particularly offensive vernacular usage from before people decided they ought to spend their time being offended on behalf of hypothetical listeners?
They were stung. "I'm not poor!" I felt so bad about it that it's stuck with me all these years. Does that mean because I've seen first hand how hurtful it can be that I should chide people whenever they use the P word?
And that analogy isn't even accurate because I'm not the one informing you that the word can be hurtful. You're using it already knowing that. So a better question is did you continue to say "oh, poor baby" to the kids who were hurt by your original comment?
I don't think you would continue using it, that was the point I was making and it sounds like you now agree with me that we shouldn't be knowingly offensive.
Yet in the years since, I still talk about poor decisionmaking, poor luck, poor performance, and poor word choice. Because it would be poor logic to go through life auditing everything I say just in case a middle schooler with a somewhat poor vocabulary might mistake my meaning.
"Poor" has non-offensive uses so you can continue to use it in other ways. You don't need to advocate for the non-offensive uses of a slur. You know regardless of the context, some people will be offended by its use.
In fact, while I wasn't around at the time I'd wager that "mentally retarded" came into an official usage specifically because it was a clinical, sterile, bloodless, and utterly anodyne descriptive term. Moron, imbecile, and idiot all were once clinical terms. And then people throw them back and forth at each other to call each other stupid, they gained an offensive connotation and new terms were needed.
In 20 years will you find it absurd if people say that "differently abled" is a slur? Will you say "this is nuts, we literally came up with that term to avoid offense?" I will!
edit: Gross that you're being downvoted. HN crowd needs a serious look in the mirror.
I think the main issue is that no matter which word/phrase is used, some people will use it as a slur, and changing it so often causes more issues than it solves.
So, that is in fact, his word.
- Heat dissipation
- Radiation shielding
- Either the most complex in-space construction ever undertaken, or the most complex distributed computing problem ever undertaken (no, Starlink satellites aren't good enough, we're orders of magnitude away from replicating the speed and reliability of connections within a single room)
- Zero flexibility, zero repairability, zero upgradability. Either it's working, or you make it burn up in the atmosphere with no in-between. Add on that the rationality of sending mountains of precision-manufactured tech containing many uncommon metals only for them to be completely lost. This makes the pricing even worse, in addition to
- Already high costs for designing, building and launching all that in addition to all the extra weight overhead you're taking in components that don't do computation, when the alternative is building a glorified warehouse in the middle of nowhere.
It just doesn't make any sense. It's a project tied up in hype and created solely so spaceflight can be hastily duct taped to the AI investment hysteria. Ask yourself why no one brought this up before or outside the context of AI, despite the lowering of space launch prices and data centers both existing before any of it.
AI compute is different (slightly higher latency is fine for inference, and there's no issue for training), and there has never been so much backlash against data centers or other infrastructure buildout. If an increasingly-non-minority of politicians get their way it will in fact be cheaper and faster to get some servers shipped to space than it will be to get the permits and build it out here on earth.
Also, most Datacenter maintenance is just dealing with the problems you see with space- power and cooling. Solar is 5x better in space and a lot more consistent. Here on land they're shutting down nuclear and imposing so many new regulations on gas and coal (and now on solar and wind) that there aren't many grids that can support growth at the scale that's being requested.
Nobody is claiming that all compute is going to space, which is what you seem to think you're arguing against. There's high-dollar demand for it right now, so if we want to be multi-planetary it's the perfect time to start tackling the "compute in space" problem that needs to be solved. Or you need to prove to future people that "All compute can be forever located on Earth" which seems a lot harder sell.
The overhead of building out grid and power infrastructure on land would then exceed the installation speed and cost relative to space based deployments.
Also assume the compute that does make it to space has a short shelf life anyways so lack of ability to repair is a non issue. As we scale manufacturing on land this will increasingly be the case.
China has already run experiments and served models from space, so we know the heat dissipation equation is solvable.
Finally you’d arrive at a similar model that’s already proven successful with Starlink but applied to serving inference.
The key question is speed to scale new deployments to meet demand. If the markets demand is near infinite, they will choose to fund space based deployments over slower land deployments.
The only hard part making the math work is the launch cost. They need reusable and reliable starship economics. If they hit that goal, it will become cheaper for training.
Putting datacenters in deserts around the equator is a much better idea than in Space. If you're really optimizing for cost that is. If you're optimizing for SpaceX meme-stock valuation the former wins
