AI company Anthropic has announced a major expansion of its compute infrastructure through a new partnership with SpaceX, alongside increased usage limits for Claude Code and the Claude API.

The company said the agreement will provide access to the full compute capacity of SpaceX’s Colossus 1 data centre, adding more than 300 megawatts of new compute power and over 220,000 NVIDIA GPUs within the next month. The expanded infrastructure is expected to improve performance and availability for Claude Pro and Claude Max subscribers as demand for generative AI services continues to surge.

As part of the announcement, Anthropic introduced several immediate changes aimed at its most active users.

The company said it is doubling Claude Code’s five-hour rate limits for Pro, Max, Team and seat-based Enterprise plans. It is also removing peak-hour limit reductions for Claude Code users on Pro and Max plans. In addition, Anthropic is significantly increasing API rate limits for Claude Opus models to support larger-scale enterprise and developer workloads.

The SpaceX partnership adds to a series of large-scale infrastructure agreements announced by Anthropic in recent months as competition intensifies among AI companies to secure long-term compute capacity.

These include an agreement with Amazon Web Services for up to five gigawatts of infrastructure capacity, including nearly one gigawatt expected to come online by the end of 2026. Anthropic also previously announced a five-gigawatt partnership with Google Cloud and Broadcom, scheduled to begin deployment in 2027, as well as a strategic collaboration with Microsoft Azure and NVIDIA involving $30 billion in Azure compute capacity.

The company additionally highlighted its $50 billion investment in American AI infrastructure with Fluidstack.

Anthropic said it currently trains and runs Claude across a mix of AI hardware platforms, including AWS Trainium chips, Google TPUs and NVIDIA GPUs, while continuing to pursue additional compute partnerships.

The company also revealed that it has expressed interest in working with SpaceX on the development of “multiple gigawatts” of orbital AI compute infrastructure, pointing to future ambitions for space-based computing systems.

Alongside domestic expansion, Anthropic said it is increasing international infrastructure capacity to support enterprise customers in regulated industries such as financial services, healthcare and government, where data residency and compliance requirements are becoming increasingly important.

The company noted that its collaboration with Amazon includes additional inference infrastructure in Asia and Europe, helping support regional AI workloads closer to customers.

Anthropic added that it is selectively expanding infrastructure in countries with secure supply chains and stable legal and regulatory environments capable of supporting large-scale AI investments.

The company also reiterated its commitment to offset consumer electricity price increases linked to its US data centres and said it is exploring ways to extend similar commitments internationally while investing in local communities hosting its facilities.
