Should Anthropic trust Elon Musk to host its models? After users on X implied that Musk could wake up one day and simply boot the AI lab from SpaceX’s servers as a way to kneecap a rival, Musk replied with glowing praise for the AI lab. He said that such a trick was “not my style.”
“I was clearly wrong about Anthropic,” Musk wrote on Thursday, referring to his September 2025 post on X in which he said, “Winning was never in the set of possible outcomes for Anthropic.” Of course, even at that time, Anthropic could already be considered a winner; the company was reported to have the biggest AI market share with enterprises.
It seems those anti-Anthropic days are behind Musk — and not just on X. As of July 2026, Anthropic is one of SpaceX’s largest customers.
To recap: Anthropic signed a deal in May to buy 300 megawatts of compute, the entire output of xAI’s Colossus 1 data center near Memphis, Tennessee. (Musk’s xAI merged with SpaceX in February.) Anthropic agreed to pay $1.25 billion per month through May 2029, a deal worth about $40 billion in revenue for SpaceX’s xAI unit. Google, by the way, also signed a deal to rent SpaceX infrastructure through June 2029, for $920 million per month.
