Anthropic Acquires Full Compute Capacity of SpaceX Colossus 1

Anthropic announced on Wednesday a deal to use the entire compute capacity of SpaceX's Colossus 1 data center. The agreement supplies more than 300 megawatts of power and access to over 220,000 Nvidia GPUs. Anthropic will apply the added resources to raise rate limits for Claude Pro, Claude Max, Team, and Enterprise users while increasing input and output allowances on the Claude Opus API.

The company stated the extra capacity will directly support paid subscribers facing current constraints. Anthropic also expressed interest in partnering with SpaceX to develop multiple gigawatts of AI compute capacity in space. The moves address growing demand for the firm's Claude Code service for developers.

Officer Ami Vora announced the agreement at Anthropic's developer conference in San Francisco. The company plans to deliver the full 300 megawatts within the month. This arrangement builds on existing work with Google, Amazon, and Microsoft for additional chip capacity.

SpaceX's Colossus 1 facility in Memphis, Tennessee, ranks among the world's largest AI clusters. The site houses dense deployments of H100, H200, and GB200 accelerators. SpaceX acquired xAI in February and has since expanded the Memphis location and begun construction on Colossus 2.

Musk posted on X that he met senior Anthropic leaders last week and found them competent and focused on safety. " Musk added that SpaceX will provide compute to AI firms taking steps to ensure their systems are good for humanity and reserves the right to reclaim resources if models cause harm.

Musk had previously criticized Anthropic's Claude model as misanthropic. The new partnership marks a shift after those earlier statements.

Background on the Companies Anthropic was founded in 2021 by former OpenAI executives and researchers. The firm is known for its Claude family of models and is in talks to raise funds at a $900 billion valuation. In March the Pentagon designated Anthropic a supply chain risk and barred it from military contracts, prompting ongoing litigation.

SpaceX and xAI have faced local complaints over air pollution from gas turbines powering the Memphis site. The new compute sales generate revenue from existing infrastructure while xAI continues its own model development.
