Anthropic Paying SpaceX $15B/Year for Compute Through 2029

Anthropic is paying SpaceX $1.25 billion per month — roughly $15 billion per year — for compute services through May 2029, according to SpaceX's IPO filing. The deal, signed earlier this year, covers use of SpaceX's Colossus 1 and expanding to Colossus 2 facilities.

Key Deal Details

• Monthly payment: $1.25 billion, ramping up from lower amounts in May and June as the deal starts.
• Term: Through May 2029.
• Scope: Anthropic will use both Colossus 1 and Colossus 2, with Nvidia GB200 capacity scaling in Colossus 2 throughout June, per Tom Brown, Anthropic co-founder and chief compute officer.

The deal is significant for Anthropic because the company's revenue is growing rapidly but has been limited by compute availability. More compute directly enables more training and inference capacity for its AI models.

For SpaceX, which reportedly brings in around $18 billion in annual revenue, this single customer represents a major revenue boost. The company stated in the IPO filing: We expect to enter into additional similar services contracts. SpaceX also noted it has enough capacity to support its own AI models while meeting obligations under these external agreements.
