SpaceX’s Rorschach test
The reactions to my comments last month on The Information’s TITV program about SpaceX needing a new story for its planned $1.5T IPO were fascinating, mainly because no one actually disagreed with the fact that SpaceX has consistently missed its targeted revenue growth over the last three years. Back in July 2023 SpaceX originally estimated revenues for the year would double to around $8B, before this whisper number was raised in November 2023 to $9B, with a forecast of $15B in 2024. That caused analysts such as Payload Space to come up with a figure of $8.7B for 2023, which is still often repeated as the actual figure, despite the NY Times finally confirming in August 2025 that SpaceX’s 2023 revenue was only $7.4B (with Starlink generating “roughly $8 billion” in revenue during 2024, implying a companywide total of ~$11B).
In 2025, SpaceX once again appears to have missed the revenue prediction of $15.5B that Musk stated publicly back in June, with Bloomberg reporting in its IPO coverage that “the company is expected to produce around $15 billion in revenue in 2025, increasing to between $22 billion and $24 billion in 2026.” That’s despite surging broadband subscriber numbers, which reached 9.2M by the end of the year as SpaceX dramatically cut the price of its terminals and reduced US residential service pricing to stimulate demand. Of course Starlink’s revenue growth is incredibly impressive, as is the speed with which it has come to dominate the satellite industry, but justifying an $800B current valuation (let alone a $1.5T IPO valuation), usually requires outperforming revenue guidance, not missing it.
Even so, it seems likely that SpaceX’s revenue target for 2026 will once again prove too optimistic, because ARPUs on those millions of customers are much lower than most analysts think (especially now there’s a $5 per month service option for suspended terminals). And the next generation D2D/DTC system won’t start launching in volume until “around Q4″ 2026 (at best since that depends on rapid progress with Starship), while SpaceX can’t access EchoStar’s AWS-4 spectrum until November 2027, so it can’t start offering a Band 70 DTC solution in the US with existing handsets until then.
It’s also undeniable that SpaceX needs more than just Starlink to justify a $1.5T valuation, given that even its expected lead investment bank, Morgan Stanley, only thinks Starlink revenues will get to $126B in 2040. So its understandable that the proposal for space-based data centers took center stage in last month’s reports of IPO preparations.
Curiously, however, data centers didn’t even rate a mention in Starlink’s end of year progress report, which focused instead on talking up the Starlink V3 satellites and the DTC constellation in particular as the key payload for Starship. And interestingly, in this progress report Starlink also modified the company’s September 2025 comments that “in most environments, [DTC] will enable full 5G cellular connectivity with a comparable experience to current terrestrial LTE service,” to instead promise that “in most environments [DTC] will enable full 5G cellular connectivity with a comparable experience to current terrestrial service.”
In many ways, Musk’s plan for space-based data centers offers a Rorschach test for potential SpaceX investors, just like Optimus does for Tesla investors. Both allow for near term demonstrations that look impressive but aren’t meaningfully revenue-generating, while allowing Musk to make long term projections of “infinite” revenues that can be (nearly) infinitely postponed.
In the case of Optimus, he’s claimed “humanoid robots will be the biggest product ever. Because everyone is gonna want one, or more than one,” while for space-based data centers, he’s claimed that “satellites with localized AI compute, where just the results are beamed back from low-latency, sun-synchronous orbit, will be the lowest cost way to generate AI bitstreams in <3 years. And by far the fastest way to scale within 4 years, because easy sources of electrical power are already hard to find on Earth."
Or put another way “Optimus and space data centers are two sides of the same coin…Optimus promises to provide all needed physical labor (and even better than a human!), while space data centers promise to provide all needed mental labor (and even better than a human!).”
But if you read yesterday’s WSJ piece on Optimus and think that Musk is simply lying again because “in public appearances, the robot is often remotely operated by human engineers” then you’ll believe the same is likely true of his plans for SpaceX’s space-based data centers. Conversely if you read that article and think that Tesla is making continued progress in opening up an untapped market opportunity where Adam Jonas “predicts that by 2050, humanoids will bring in $7.5 trillion in annual revenue across the industry globally,” you’ll probably have the same reaction about space-based data centers. And of course the latter are the investors that SpaceX actually wants for any IPO.
This is not to say that the market for either is non-existent: just like many companies are working on robots (with or without legs!), there is plenty of interest in space-based data centers. Both will also be particularly useful to the DoD, and especially in the space market the US government is seen as the best source of new revenue by many players right now.
And SpaceX has substantial advantages both in access to cheap launch, and in the ability to build a distributed network of data centers based on the Starlink V3 bus (which is a much better solution than a handful of extremely large space-based data centers several km in diameter, not least because achieving low latency requires the data center to be in view). However, that’s very different to saying revenue will be “infinite” or that this market can justify a $1.5T valuation for SpaceX.
But to return to my original interview, its particularly amusing to note the CEO of Starcloud suggesting in a subsequent TITV interview that this was “the dumbest thing I’d heard in a quite a long time”, because the dumbest thing I’ve heard in quite a long time is Starcloud’s business plan, which (if you take their story about launching huge arrays into space at face value) is essentially totally dependent on gaining access to Starship launches at cost.
Of course that means sucking up to Elon Musk is a necessity, but when one of SpaceX’s key competitive advantages for Starlink (and a key source of value in any IPO) lies in exploiting the huge difference between the cost and price of Falcon 9 launches, there’s no reason to believe that the same wouldn’t be true for Starship. In other words, SpaceX will be able to launch its own space-based data centers at a much lower cost, compared to the price of Starship launches for third parties, allowing SpaceX to gain far more scale than any other player at much lower cost, just as it has done with Starlink. In fact, I understand that all Starcloud has is some interesting in-space cooling technology, which only becomes valuable in extremely large arrays, and that’s unlikely to be useful if SpaceX’s distributed space-based data center architecture proves more cost effective.
