Anthropic and SpaceX secure Colossus 1 to double Claude AI capacity

On May 6, 2026, Anthropic announced a partnership with SpaceX to use all compute capacity at the Colossus 1 data center in Memphis, adding over 300 MW and 220,000+ Nvidia GPUs within a month. The deal lets Anthropic immediately double Claude Code’s five-hour rate limits, lift peak‑hour throttling for Pro/Max, and substantially raise Opus API rate limits.
