Anthropic has signed an agreement with SpaceX to use the full compute capacity of Colossus 1, a data center in the United States. The deal gives Anthropic access to more than 300 megawatts of capacity, backed by over 220,000 Nvidia GPUs, within the month.
Anthropic head of product Ami Vora announced the partnership at the company’s developer conference in San Francisco. The company says the additional capacity will directly benefit subscribers of its Claude Pro and Max plans.
The deal addresses a problem Anthropic has been struggling with: surging demand that has led to aggressive usage caps. Alongside the SpaceX agreement, Anthropic announced several changes to its service limits:
- Claude Code’s five-hour rate limits are doubling for Pro, Max, Team, and seat-based Enterprise plans
- Peak hour usage reductions are being removed for Pro and Max users
- API rate limits for Claude Opus models are increasing
Colossus 1 is operated by SpaceX and features dense deployments of H100, H200, and GB200 accelerators, according to SpaceX. The cluster was built to support AI training, fine-tuning, and inference workloads.
The SpaceX agreement is one of several large compute deals Anthropic has announced recently. Others include agreements with Amazon, Google, Broadcom, Microsoft, and Nvidia.
As part of the SpaceX deal, Anthropic has expressed interest in exploring orbital AI compute capacity. SpaceX says space-based infrastructure could offer sustainable power with less impact on Earth, though it acknowledged engineering challenges remain.
