Elon Musk praised Anthropic on X, calling it "the leader in AI" and stating that he would "never cut them off in a way that hurt them badly, even as a competitor," after users suggested he could boot the AI lab from SpaceX's servers. "I was clearly wrong about Anthropic," Musk wrote on Thursday, referring to his September 2025 post. As of July 2026, Anthropic is one of SpaceX’s largest customers, having signed a deal in May to buy 300 megawatts of compute, the entire output of xAI’s Colossus 1 data center near Memphis, Tennessee. 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. Musk cited Tesla’s 2014 decision to not initiate patent lawsuits and its opening of the Supercharger network as proof of his style. He also noted that "SpaceX launches competing satellite systems with no increase in price or use of unfair terms." The article notes contractual consequences would exist if Musk shut down Anthropic’s infrastructure, and that SpaceX’s engineers may learn from supporting Anthropic’s AI.
