Earlier this month, xAI signed a major compute deal with Anthropic, pledging billions of dollars a month for exclusive use of the company’s Colossus cluster. It was a coup for both companies, giving xAI much-needed revenue and helping Anthropic catch up in the race for compute. However, Elon Musk downplayed the extent of SpaceX’s commitment to the deal on X. "SpaceX has not committed to leasing Colossus for years, although it’s possible that may be what happens," he said. "This is a 180 day lease with 90 day notice mutual cancellation thereafter. The short term was our request, not Anthropic’s. We won’t leave them hanging and will provide a reasonable off-ramp, but if compute gets super tight I said we might need it back at some point." Musk’s statement contradicts SpaceX’s recent S-1 filing, which confirms the standard 90-day cancellation but presents the deal as a three-year agreement. Page F-62 of the filing reads: "On May 3, 2026, the Company entered into a cloud services agreement with Anthropic PBC, an AI research and development public benefit corporation, with respect to access to compute capacity. Pursuant to this agreement, the customer has agreed to pay a monthly fee through May 2029, with capacity ramping in May 2026 at a reduced fee. The agreement may be terminated by either party upon 90 days’ notice. The customer will retain ownership and intellectual property rights in its content, AI models, and related data." The same language is repeated on F-96 and in slightly varied form on pages 13 and 146. xAI did not respond to a request for clarification. While there may be debate over whether Anthropic agreeing to pay for a service means the same as SpaceX agreeing to provide it, the lease term is clearly defined in the filing. The SEC may not take action, and even if they did, Elon Musk likely wouldn’t care. However, the discrepancy raises concerns about potential misrepresentation during a company’s quiet period. *Source: [techcrunch](https://techcrunch.com/2026/05/28/how-long-is-anthropics-lease-with-spacex-opinions-vary/)*
