Anthropic on Wednesday unveiled a new partnership with Elon Musk’s SpaceX, securing the full compute capacity of the company’s Colossus 1 data center in Memphis, Tennessee, in the United States.

Under the agreement, Anthropic will gain access to more than 300 megawatts of computing power and has also expressed interest in collaborating with SpaceX to build multiple gigawatts of compute capacity in space.

The company said the added infrastructure will directly boost performance and availability for its paid Claude Pro and Claude Max subscribers.

The announcement follows Musk’s decision to merge SpaceX with his rival AI venture, xAI, earlier this year. Musk has also repeatedly criticized Anthropic over its disputes with the U.S. government.

Musk has argued that Anthropic is “doomed to become the opposite of its name,” suggesting it would turn misanthropic, and has questioned whether there is a “more hypocritical company than Anthropic.”

“Anthropic hates Western Civilization,” Musk wrote in February.

However, on Wednesday, Musk struck a different tone. In a post on X, he said he had spent significant time over the past week with senior members of the Anthropic team and came away “impressed.”

“Everyone I met was highly competent and cared a great deal about doing the right thing. No one set off my evil detector,” Musk wrote. “So long as they engage in critical self-examination, Claude will probably be good.”

Musk spent much of the past week in federal court in Oakland, California, testifying over three days in his lawsuit against OpenAI and its chief executive, Sam Altman.

In a separate post on X on Wednesday, Musk said xAI “will be dissolved as a separate company” and rebranded as SpaceXAI.

xAI has been expanding its data infrastructure, largely centered in Memphis, as it competes in the fast-growing AI market against OpenAI, Google and Anthropic. Colossus 1 is the company’s largest facility to date.
