In May 2026, SpaceX signed cloud services agreements with Anthropic, under which Anthropic will pay $1.25 billion per month through May 2029 for access to the COLOSSUS and COLOSSUS II supercomputers, with a reduced fee during the initial ramp-up period. The agreements can be terminated by either party with 90 days' notice.", "body_md": "We have the ability to use compute resources to support our proprietary AI applications (such as Grok 5, which is currently being trained at COLOSSUS II), while also providing access to select compute capacity to third-party customers. For example, in May 2026, we entered into Cloud Services Agreements with Anthropic PBC (“Anthropic”), an AI research and development public benefit corporation, with respect to access to compute capacity across COLOSSUS and COLOSSUS II. Pursuant to these agreements, the customer has agreed to pay us $1.25 billion per month through May 2029, with capacity ramping in May and June 2026 at a reduced fee.
