SpaceX and Anthropic have struck a deal that gives the Claude maker exclusive access to all compute capacity on the Colossus 1 AI supercomputer in Memphis, Tennessee. The lease runs for an initial six months with mutual 90-day cancellation rights, a structure Elon Musk says SpaceX itself requested.

The arrangement hands Anthropic more than 220,000 Nvidia GPUs, including H100, H200, and GB200 models, along with over 300 megawatts of power. That is a staggering amount of compute for inference workloads, the kind of processing that keeps chatbots responsive when millions of users hit them at the same time.

What Anthropic gets, and what it means for Claude

Colossus 1’s firepower is aimed squarely at Anthropic’s inference stack, making Claude faster and more available rather than training the next frontier model from scratch.

The direct beneficiaries are Claude Pro and Claude Max subscribers, who can expect increased service limits and computational headroom.
