SpaceX has acquired xAI, merging two of Elon Musk’s biggest bets as AI infrastructure demand keeps climbing. Musk is framing the move around a specific target, AI data centers in space.
His argument is that today’s AI progress depends on massive Earth-based data centers that consume huge power and require intense cooling. He says shifting more compute to orbit solves those constraints with abundant solar energy and room to scale.
SpaceX is already pushing the concept into the regulatory process. It sought permission from the Federal Communication Commission to launch a constellation of 1 million satellites, describing a network of solar-powered data centers meant to handle explosive growth in AI-driven data demand. Musk also said the lowest-cost way to generate AI compute will be in space within two to three years.
The filing makes the plan concrete
The FCC request is the most tangible signal yet. A constellation at that scale points to more than communications, it suggests in-orbit processing where data can be handled above the atmosphere instead of routed back to terrestrial facilities for every step.
That helps explain why xAI fits under SpaceX. The merger links AI software and demand directly to a company that can deploy hardware in space, and it also reads like a way to strengthen xAI’s access to capital and compute resources.
Power costs are driving the urgency
AI’s appetite for compute is pushing infrastructure spending higher. Next-generation models may need far more power than older ones, and Goldman Sachs expects data center power demand to rise sharply by 2030.
Microsoft reported $37.5 billion in capital expenditures in the last quarter of 2025, while Meta reported $22.14 billion. The story also notes some US residents have seen higher electricity bills, and a Bloomberg News analysis found steep increases near data centers versus five years earlier.
The next signals are regulatory and operational
The first gate is regulatory approval for the satellite plan. The second is execution, including a possible culture clash, since the reporting you shared includes a former xAI staffer warning about different working styles.
An IPO is another watch point. Musk confirmed in December that he was planning an initial public offering for SpaceX, reportedly valued around $1.5 trillion, and combining the companies may reshape that pitch if SpaceX can turn filings into timelines and deployments.
