en.Wedoany.com Reported - Space Exploration Technologies Corp. (SpaceX) officially filed its S-1 registration statement with the U.S. Securities and Exchange Commission on May 20, Eastern Time, disclosing its financial condition and core business progress to the public for the first time. In the artificial intelligence business segment, SpaceX disclosed the specific financial terms of the compute power cooperation agreement with Anthropic, which had been officially announced just the day before — Anthropic commits to paying $1.25 billion per month (approximately RMB 9 billion) over the next three years, with the cumulative contract total approaching $45 billion by May 2029, to access the full compute capacity of SpaceX's Colossus 1 supercomputing cluster.
The S-1 filing shows that May and June 2026 will be a ramp-up phase with gradually increasing compute capacity, during which Anthropic will be billed at preferential rates; starting July 2026, the full-rate billing phase officially begins, with monthly payments of $1.25 billion until the contract expires in May 2029. The filing also discloses that either party may terminate the agreement with 90 days' prior notice to the other, granting both sides the flexibility to adjust during the three-year cooperation period. The contract is expected to generate approximately $1.25 billion in monthly cash flow for SpaceX, with a cumulative three-year contract value of nearly $45 billion, making it one of the most significant recurring revenue sources for SpaceX prior to its IPO.
Colossus 1 is the flagship supercomputing cluster that SpaceX previously built for its AI subsidiary xAI, located in Memphis, Tennessee. It is equipped with over 220,000 Nvidia GPUs, including H100, H200, and the latest GB200 accelerators, with a total compute power scale exceeding 300 megawatts. On May 6, SpaceX and Anthropic jointly announced this collaboration, through which Anthropic gains access to the full compute capacity of this supercomputing cluster and committed to completing integration within one month. Anthropic stated that day that it will use this additional compute power to directly increase the paid service limits for its Claude Pro and Claude Max users.
The compute power infusion has already yielded immediate results. Anthropic Chief Product Officer Ami Vora announced at the May 6 developer conference that the five-hour rolling usage cap for Claude Code has been doubled across the board, covering all tiers of Pro, Max, Team, and Enterprise plans, with the peak-hour rate limiting mechanism simultaneously removed; the application programming interface rate limits for the Claude Opus model series have been significantly increased, with some tiers seeing the per-minute input token limit raised by more than 15 times.
The contract disclosed by SpaceX in its prospectus marks the largest single order in the global AI compute power service market and is also one of the most significant commercial highlights in the upcoming SpaceX IPO prospectus. New Street Research analysts previously estimated that this contract could contribute $3 billion to $4 billion in annual revenue for SpaceX, with cash profits exceeding $2.5 billion. SpaceX confidentially submitted its S-1 filing on April 1, targeting a valuation range of $1.75 trillion to $2 trillion, planning to raise approximately $75 billion, and is expected to list on the Nasdaq on June 12. Both Anthropic and OpenAI plan to go public as early as this year.
According to the agreement terms previously disclosed by both parties, Musk retained a special right in the agreement: if Anthropic's AI engages in behavior harmful to humanity, SpaceX has the right to reclaim the compute power. This clause grants SpaceX unilateral control to cut off service and adds a unique safety and ethical safeguard to this massive commercial contract.
The agreement also touches on the long-term vision of space-based compute power. In its May 6 announcement, Anthropic expressed its intention to collaborate with SpaceX on developing multiple gigawatt-class orbital AI compute capacity. SpaceX had previously submitted an application to the U.S. Federal Communications Commission, planning to deploy up to 1 million low-Earth orbit satellites to build an orbital data center network. Although this vision is still in the conceptual stage, SpaceX listed it in the S-1 filing as a strategic extension direction for its AI infrastructure business.
