Key Points

Anthropic is securing the full compute capacity of SpaceX’s Colossus-1 data center—over 300MW and more than 220,000 NVIDIA GPUs—to scale Claude workloads.
The additional compute is expected to be operational within about a month, indicating a near-term expansion of Anthropic’s training/inference capacity.
Anthropic is also doubling the rate limits for Claude Code, aiming to increase throughput for developer use cases.
For its Opus models, Anthropic is significantly raising API limits, which should improve availability and reduce throttling for customers.
Overall, the moves combine infrastructure scaling with product-level capacity increases across both Claude Code and Opus APIs.
