SpaceX Reveals Orbital AI Data Center Plans Ahead of $1.75 Trillion IPO

TLDR

• SpaceX CEO Elon Musk says building orbital AI data centers requires no new technology
• The first AI satellite would handle 150 kilowatts of computing power, comparable to an Nvidia GB300 rack
• SpaceX is targeting 1 gigawatt of space-based AI computing by end of 2027
• The company is seeking a $1.75 trillion valuation in what could be a record IPO
• SpaceX plans to build its own AI chips through a factory called Terafab, partnering with Tesla and Intel

SpaceX has outlined plans to build AI data centers in orbit, using technology already developed for its Starlink satellite network. The announcement came ahead of the company’s highly anticipated IPO, which is expected to value SpaceX at around $1.75 trillion.

CEO Elon Musk made the case that orbital AI computing is not as hard as it sounds. “A lot of this is technology we’ve already made for the Starlink V3 satellites,” Musk said. “We don’t think this is a super hard problem compared to the things we already do.”

The comments came in a roughly 31-minute video released by SpaceX on Monday.

What the First AI Satellite Would Do

SpaceX revealed a draft design for its first AI satellite, called AI1. At peak performance, it would handle 150 kilowatts of AI computing power. Musk compared that to a single Nvidia GB300 server rack used in ground-based data centers.

The satellites would be powered by solar energy and cooled by radiating heat into space. SpaceX engineer Ian Dahl noted they would actually be simpler than Starlink satellites, since they would not need large broadband antennas.

Satellites could connect to each other through laser links or link into the existing Starlink network.

SpaceX has asked the Federal Communications Commission to approve up to 1 million AI satellites in low-Earth orbit.

The Bigger Plan and the IPO

SpaceX said it wants to reach an annualized rate of 1 gigawatt of space-based AI computing by the end of 2027. Musk said that figure should be taken with a “grain of salt.” The company’s IPO filing had set a more conservative target, with first satellites launching as early as 2028 and revenue starting by end of the decade.

The company’s IPO filing argued that Earth-based AI infrastructure faces growing power constraints. SpaceX sees orbital computing as a way around that problem.

To drive down costs, SpaceX plans to use its Starship rocket for large-scale launches. It is also working on Terafab, a planned chip factory being developed with partners Tesla and Intel.

Not everyone is convinced the timeline is realistic. Rivals like Blue Origin and Amazon founder Jeff Bezos have pointed to high chip costs and launch expenses as barriers. One independent researcher’s model suggested the economics do not yet work.

SpaceX’s AI satellite factory in Bastrop, Texas, is expected to reach meaningful production by the end of next year.

The IPO is expected to launch later this week.
