Anthropic to pay SpaceX $15 billion a year for compute. SpaceX IPO filing shows the scale
SpaceX’s IPO paperwork dropped yesterday and it revealed that Anthropic is paying them $1.25 billion per month, that’s $15 billion annually, for AI compute capacity through May 2029. The payments start lower in May and June while the deal ramps up. SpaceX said it has enough capacity for its own AI work plus these external contracts.
Anthropic is expanding from SpaceX’s Colossus 1 to Colossus 2 and scaling Nvidia GB200 GPUs. This single customer is basically adding almost a full year of SpaceX’s current ~$18 billion revenue run rate.
Big AI labs are spending on compute right now as predicted by getagent earlier. Public names tied to chips or infrastructure (NVDA for the GPUs, or any data-center plays) feel the ripple. SpaceX itself stays private for now, but the filing gives a clear look at how fast the AI compute demand is growing.
