Elon Musk announced that SpaceX's leasing agreement with Anthropic for the Colossus AI training data center cluster is initially set for six months. Musk noted that while the current lease is short-term, there is potential for extension to 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 clusters in Memphis, Tennessee, through May 2029. Despite the long-term nature of the overall agreement, SpaceX's recent regulatory filing allows either party to terminate the contract with 90 days' notice, though it did not specify the six-month lease term.
