SpaceX says it has acquired xAI
On February 2, 2026, SpaceX said it acquired xAI and argued that orbital data centers are the way to scale AI compute, with a worked example of 100 GW added per year.

Summary
SpaceX said it had acquired xAI, putting rockets, Starlink, direct-to-phone service, and xAI’s models and the X platform in one company description. The post, signed by Elon, argues that terrestrial data centers cannot supply the electricity AI training and inference will demand, and that solar power in orbit is the long-term alternative.
The near-term mechanism is Starship launch rate. SpaceX said 2025’s global orbital launch total was only about 3,000 tons of payload, mostly Starlink satellites on Falcon. It said Starship would begin launching V3 Starlink satellites, with each flight adding more than 20 times the constellation capacity of a Falcon V2 Starlink launch, plus a later direct-to-phone generation.
The compute arithmetic is presented as Elon’s estimate, not a measured plant: launches every hour at 200 tons, a million tons a year of satellites at 100 kilowatts of compute per ton, adding 100 gigawatts of AI capacity a year, with a later path to 1 terawatt a year from Earth. A further step, factories on the Moon and an electromagnetic mass driver, is given as 500 to 1,000 terawatts a year of satellites. That lunar figure is speculative architecture.
He also wrote that within two to three years, space could be the cheapest place to generate AI compute. Treat that sentence as a prediction.
Key facts
| Fact | Label |
|---|---|
| SpaceX said it acquired xAI | Company announcement |
| About 3,000 tons to orbit in 2025, called the busiest year | Company historical comparison |
| Each Starship V3 Starlink flight claimed at more than 20 times a Falcon V2 flight’s capacity add | Company claim |
| Example: 1 million tons/year at 100 kW per ton equals 100 GW/year | Company arithmetic, labeled as a path |
| Two-to-three-year cost prediction for space-based compute | Prediction, attributed to Elon in the post |
Why it matters
This is the corporate link between xAI and SpaceX. The Grok and Colossus pages track terrestrial compute. This post is the company’s case that the next increment is orbital, and it depends on Starship cadence that the flight-test posts show is still being learned. The Moon mass-driver passage belongs with speculative architecture, not with an approved lunar program.
