Anthropic announced in May 2026 that it has signed an agreement with SpaceXAI to access computing resources from xAI’s Colossus 1 supercomputer, located at a data center in Memphis, Tennessee. The deal was revealed by Anthropic executives on stage at the company’s annual developer conference in San Francisco.
SpaceX and xAI, both owned by Elon Musk, merged earlier this year to form the combined entity SpaceXAI. Under the agreement, Anthropic will gain access to more than 300 megawatts of computing capacity — approximately 220,000 Nvidia GPUs, including H100, H200, and GB200 chips. Both companies said the additional capacity will be used to “directly improve capacity for Claude Pro and Claude Max subscribers.”
The deal comes as Anthropic has faced growing service disruptions to Claude Code, its AI coding tool, due to limited computing resources. According to Anthropic, the average developer now spends at least 20 hours per week running Claude Code, placing significant strain on available infrastructure.
The partnership may also benefit SpaceXAI, which is seeking to go public as soon as next month. SpaceXAI’s blog post noted that Anthropic has “expressed interest” in partnering on “orbital AI compute capacity” — data centers in space. Having Anthropic as a potential customer could help bolster investor confidence ahead of the IPO.
The deal represents a notable shift for Musk, who earlier this year publicly criticized Anthropic’s AI models on X, calling the company’s policies “misanthropic” and “evil.” He has since changed his position, writing that he “spent a lot of time last week with senior members of the Anthropic team” and “was impressed.”
The SpaceXAI arrangement is one of several major computing commitments Anthropic has made recently. The Information reported that Anthropic committed to spend $200 billion on Google’s AI cloud services and TPU chips, and last month the company committed “more than $100 billion over the next ten years” to Amazon technologies. Contracts with Anthropic and OpenAI now account for “more than half of the $2 trillion in backlogs at major cloud providers,” according to the same report.
