Anthropic Takes Full Colossus 1 Capacity — Claude Code Limits Double on the Spot
Anthropic’s SpaceX Colossus 1 deal (>300 MW, >220k NVIDIA GPUs) lands with immediate Claude Code five-hour limit doubles, peak-hour cuts removed for Pro/Max, and higher Opus API limits. Multi-cloud compute (AWS, Google, Azure, now SpaceX) is the product lever — capacity figures are company-stated.
Frontier product experience is gated by fleets. Anthropic’s Colossus deal is infrastructure that shows up as higher Claude Code limits the same month — not a distant GW press release.
Anthropic (May 6) announced a partnership with SpaceX to use the full capacity of the Colossus 1 data center — more than 300 megawatts and over 220,000 NVIDIA GPUs — enabling immediate increases in usage limits for Claude Code and the Claude API. Capacity available within the month of the announcement, per Anthropic.
Capacity and prior stack
| Commitment | Scale (Anthropic) |
|---|---|
| Colossus 1 (SpaceX) | >300 MW; >220k NVIDIA GPUs (H100/H200 and newer) |
| Amazon | Up to 5 GW (nearly 1 GW Trainium/Graviton by end-2026) |
| Google + Broadcom | 5 GW (starting 2027) |
| Microsoft / NVIDIA Azure | $30B Azure capacity partnership |
| Fluidstack | $50B American AI infrastructure investment |
Anthropic trains/runs Claude across AWS Trainium, Google TPUs, and NVIDIA GPUs; exploring further options including potential orbital AI compute with SpaceX.
Limit changes (immediate)
- Claude Code five-hour rate limits doubled for Pro, Max, Team, and seat-based Enterprise.
- Peak-hours limit reduction removed for Claude Code on Pro and Max.
- API rate limits raised considerably for Claude Opus models (tiers in Anthropic docs).
Also: commitment to cover consumer electricity price increases caused by its U.S. data centers; Alberta government cited as a Claude Code customer for vuln review/fix.
Claims vs checks
MW/GPU counts, limit changes, and prior GW deals are Anthropic primary. Axios/Engadget/TNW confirm announcement framing. Exclusive “full capacity” is contractual language from Anthropic — independent power-meter audits are not public.
Limits
- GPU mix and exact rack delivery schedule not fully itemized.
- Limit doubles are plan-scoped; Enterprise custom contracts may differ.
- Orbital compute is exploratory, not a shipped product.
