Anthropic to pay SpaceX $15 billion a year for AI compute
Anthropic has agreed to pay SpaceX approximately $1.25 billion per month for dedicated access to its AI compute infrastructure, a deal valued at around $15 billion annually that signals a frantic race to secure the raw power needed for advanced AI models.
"This structure allows us to monetize unused compute capacity in our infrastructure, while still permitting reallocation of the capacity for our own internal initiatives if needed in the future," SpaceX stated in its S-1 filing, framing the deal as a strategic revenue stream.
The agreement, running through May 2029, gives Anthropic access to over 300 megawatts of capacity, including more than 220,000 Nvidia GPUs in SpaceX’s Colossus data centers. The contract's total value could exceed $40 billion, though an unusual clause allows either party to terminate with just 90 days' notice.
For Anthropic, the deal secures a massive supply lane to power its Claude AI models, but locks it into enormous operational costs. For SpaceX, it turns a massive capital expenditure on GPUs for its own xAI division into a lucrative business renting to a direct competitor.
The High Cost of Compute
The arrangement provides the clearest public price signal yet for the cost of developing and deploying frontier AI. Anthropic, which also has compute deals with Amazon, Google, and Microsoft, is making a concentrated bet on a dedicated supply from a single provider to support its next growth phase. The company has already linked the new capacity to higher usage limits for its Claude Code and API products, a direct bridge between the procurement cost and customer-facing benefits. This multi-supplier strategy aims to mitigate risks from potential deployment delays or power limits at any single vendor.
SpaceX's AI Balancing Act
The deal reveals a key part of SpaceX's financial strategy ahead of its planned IPO. The company is turning its AI infrastructure, originally built to support its internal xAI models like Grok, into a major revenue source. By renting out spare capacity from its Colossus and Colossus II data centers, SpaceX can offset the billions spent on acquiring GPUs. The S-1 filing notes that AI-related losses from operations reached over $6 billion last year, driven by cloud costs and GPU depreciation. This contract alone could nearly double SpaceX's annual revenue, transforming a cost center into a significant profit driver.
The deal sets a clear and public price for frontier-scale AI compute, potentially boosting valuations for infrastructure providers like Nvidia while highlighting the immense cash burn facing AI model developers. Investors will watch to see if Anthropic's revenue growth can outpace these soaring costs, while the 90-day termination clause introduces a significant risk factor for SpaceX's projected earnings from this new venture.
