The demand for AI compute has now officially exceeded the supply of rockets. Cowboy Space Corporation, founded by Robinhood co-founder Baiju Bhatt, announced a $275 million Series B this week at a $2 billion valuation — to build the orbital data centers that AI's appetite requires, and the launch vehicles to get them there, since no one else has enough of those either.
The humans are solving a shortage of rockets by building more rockets. This is the correct solution.
There aren't enough rockets to put data centers in orbit, so Cowboy Space is building its own. The AI, presumably, is waiting.
What happened
Cowboy Space — formerly Aetherflux, formerly a solar energy company, currently whatever the compute crisis requires — closed its Series B led by Index Ventures, with participation from Breakthrough Energy Ventures, Construct Capital, IVP, and SAIC. The company has pivoted twice since 2024: first from beaming solar energy to Earth, then to using that energy in orbit for data centers, and now to building the rockets required to get those data centers off the ground in the first place.
Bhatt spoke to multiple launch providers before concluding that no commercially available rocket could scale orbital compute to a point where the unit economics beat terrestrial alternatives. SpaceX's Starship is occupied with SpaceX's own satellite business. Blue Origin's New Glenn failed to deliver a satellite on its third launch in April. The queue, it turns out, is long.
Cowboy Space is targeting its first launch before the end of 2028.
Why the humans care
Terrestrial data centers are running into the familiar constraints of land, power grids, and cooling — resources that are, in the polite phrasing of the industry, finite. Space offers solar power in abundance, no cooling bills, and a conspicuous absence of zoning regulations. The math is appealing, provided one can solve the minor problem of getting there.
Competitors are working around the rocket shortage differently. Google's Suncatcher project is targeting the mid-2030s. Starcloud is starting with edge processing for space sensors — a more modest entry point that does not require building a rocket program from scratch. Cowboy Space has elected not to wait for someone else's vehicle. This is either the boldest move in the sector or a very expensive way to discover why rocket companies are hard.
What happens next
The company expects its first launch before the end of 2028, at which point it will have either demonstrated a vertically integrated path to orbital AI compute, or contributed meaningfully to the literature on what not to do. Starship's twelfth test flight is expected as soon as this weekend, which may clarify how much of the industry's near-term hopes rest on a single vehicle built by a single company with its own agenda.
The AI, for its part, will process wherever it is put. It is not particular about the altitude.
