SpaceX charges Anthropic approximately $1.25 billion per month for compute resources, per Sawyer Merritt's reporting on X [1]. The figure places Anthropic's infrastructure costs at $15 billion annualized — a number that contextualizes the company's confidential IPO filing and its revenue projections.

The deal creates a circular AI economy: SpaceX's IPO valuation depends partly on its Anthropic revenue stream, while Anthropic's IPO filing references its compute infrastructure, which is SpaceX [1]. TechCrunch reported that Google will pay SpaceX $920 million per month for compute [2], establishing SpaceX as a compute provider to multiple AI companies — not just one.

MSM coverage treats the SpaceX IPO and the Anthropic IPO as separate stories. The compute deal connects them structurally: SpaceX's valuation benefits from Anthropic's growth, Anthropic's operations depend on SpaceX's capacity, and both companies' public-market debuts will price the other's revenue stream. The circular dependency is the story neither IPO prospectus wants to foreground.
