SpaceX CEO Elon Musk announced that the company has agreed to lease its Colossus AI training data center cluster to Anthropic for an initial period of six months. Musk noted that while the current agreement is short-term, there is potential for extension over several years. The agreement, which began earlier this year, involves Anthropic paying $1.25 billion monthly to utilize the computing power of SpaceX's Colossus and Colossus II data centers in Memphis, Tennessee, with a validity until May 2029. However, regulatory filings indicate that either party can terminate the agreement with a 90-day notice, though these filings did not specify the six-month lease term.
