Anthropic has taken over the full computing capacity of SpaceX's Colossus‑1 data center, gaining over 300 megawatts

Anthropic announced it has assumed the full computing capacity of the Colossus‑1 data center operated by SpaceX, gaining access to more than 300 megawatts of power and in excess of 220,000 NVIDIA GPUs. The company said this capacity is expected to be brought online within a month and will be used to expand compute for its Claude family of models. As part of the rollout, Anthropic is raising customer product limits. Five‑hour rate limits for Claude Code will double within a month for Pro, Max, Team, and Enterprise accounts, and peak‑time throttling for Pro and Max customers will be removed to allow steadier throughput during busy periods.

Anthropic has also increased API per‑minute token caps for Claude Opus across tiers. For Tier 1, input allowances rise from 30,000 to 500,000 tokens and output from 8,000 to 80,000. Tier 2 input increases from 450,000 to 2,000,000 and output from 90,000 to 200,000. Tier 3 moves from 800,000 to 5,000,000 input and 160,000 to 400,000 output. Tier 4 expands input from 2,000,000 to 10,000,000 and output from 400,000 to 800,000.

The Colossus‑1 agreement complements a set of large compute commitments Anthropic has disclosed: up to 5 gigawatts with Amazon, 5 gigawatts with Google and Broadcom, $30 billion of Azure capacity with Microsoft and NVIDIA, and a $50 billion investment with Fluidstack. Anthropic framed these multi‑vendor arrangements as part of a strategy to scale Claude beyond the limits of its internal datacenters.

Anthropic also described operational and policy commitments tied to its data center footprint. It said it will cover any electricity price increases for U.S. consumers that result from its facilities and is evaluating whether to extend that pledge to future locations. The company said it is exploring "orbital AI compute capacity" as a nontraditional deployment option and will only partner with democratic countries whose legal and regulatory frameworks support investments of this scale and provide a secure supply chain. Observers have noted that this policy draws attention given SpaceX’s ownership.

Higher per‑minute token quotas and the removal of peak throttles will allow larger batches, higher sustained throughput, and reduce the need for client‑side rate‑shaping. Anthropic advised teams to review tiered limits and account plans ahead of Colossus‑1 coming online to ensure workloads can take advantage of the expanded capacity.
