HAWTHORNE, Calif. — SpaceX's fast-growing artificial intelligence business has hit a financial milestone, posting its first-ever quarter of positive adjusted EBITDA and pulling in some of the biggest names in AI as paying customers, including companies that compete directly with Grok. The numbers point to a compute empire that is scaling quickly and beginning to pay for itself.
A Breakout Quarter
SpaceX's AI unit generated $2.56 billion in revenue, up 247% from a year earlier, with the core AI Solutions and Infrastructure segment contributing $2.194 billion. For the first time, the segment's adjusted EBITDA turned positive, reaching $1.1 billion. Management said signed Cloud Services Agreements now total $14.1 billion, and it added another $6.7 billion of cloud revenue over a six-month stretch beginning in October.
The scale of investment behind those numbers is striking. The company spent roughly $18.37 billion on capital projects in the quarter, including about $15.83 billion on AI computing power, and says it is targeting more than 2 gigawatts of capacity by year-end. Crucially, management claims a payback of under one year on new compute capital, a thesis that analysts at UBS said sets up SpaceX for its strongest quarter yet.
Renting to the Competition
Perhaps the most telling sign of demand is the customer list. SpaceX is now leasing compute to Google and Anthropic, both of which field AI assistants that compete with Grok. As 24/7 Wall St. reported, Musk has said he expects only about 10% of SpaceX's compute to go toward training Grok, leaving the vast majority available to rent to the broader market.
