Anthropic has signed a deal with SpaceX to use the entire computing capacity of Colossus 1, SpaceX’s flagship AI data center located in Memphis, Tennessee.
The agreement gives Anthropic access to more than 300 megawatts of new capacity, backed by over 220,000 NVIDIA GPUs, all of which will come online within this month. According to CEO Dario Amodei, this deal was built specifically to ease capacity pressure on the company’s most active users.
What Changes for Claude Users
Anthropic says it will be doubling Claude Code’s five-hour rate limits for Pro, Max, Team, and seat-based Enterprise plans. The company is also removing the peak hours limit reduction on Claude Code for Pro and Max accounts and raising API rate limits considerably for Claude Opus models. Free plan users are not included in these changes.
Anthropic acknowledged as early as April 2026 that the explosive demand for Claude Code and its agentic tools had created what it described as “inevitable tension” on its servers. Developers were experiencing rate limits, slowdowns during peak hours, and increasingly frequent service interruptions.
Anthropic had even been contemplating the idea of dropping Claude Code access from its $20-a-month Claude Pro plan. But the SpaceX deal has now given the company room to move in the opposite direction.
What Is Colossus 1?
Colossus 1 features over 220,000 NVIDIA GPUs, including dense deployments of H100, H200, and next-generation GB200 accelerators. The cluster is built to deliver parallel performance for large language models (LLMs), multimodal systems, scientific simulations, and generative AI at frontier scale.
SpaceX describes it as one of the world’s largest and fastest-deployed AI supercomputers.
Anthropic’s Broader Compute Push
The SpaceX deal sits inside a much larger infrastructure strategy. Anthropic also has an up to 5 gigawatt agreement with Amazon that includes nearly 1 gigawatt of new capacity by the end of 2026, a 5 gigawatt agreement with Google and Broadcom beginning to come online in 2027, a strategic partnership with Microsoft and NVIDIA that includes $30 billion of Azure capacity, and a $50 billion investment in American AI infrastructure with Fluidstack.
Anthropic’s annualized revenue run rate crossed $30 billion, up from $9 billion at the end of 2025. The company also grew 80 times over in Q1 2026 alone, far outpacing an internal plan for 10 times growth. That scale of demand is what made a deal of this size necessary.
The Space Angle
Beyond the immediate compute expansion, both companies have signaled an interest in what comes next. Anthropic expressed interest in partnering with SpaceX to develop multiple gigawatts of orbital AI compute capacity. Space-based data centers could be operated continuously using sunlight, without requiring physical land or placing heavy demands on water, power, and conventional cooling resources.
SpaceX has already filed documents with the U.S. Federal Communications Commission regarding the launch of up to a million satellites to create an orbital data center.
The Musk Factor
The partnership is worthy to highlight given the public history between Elon Musk and Anthropic. As recently as February 2026, just three months before the agreement was signed, Musk was posting direct attacks against Anthropic on X, calling the company “misanthropic” and accusing it of bias in Claude’s responses.
In a shift before the announcement, Musk spent time with senior members of the Anthropic team and said he was “impressed” by their work on AI safety. Musk added that SpaceX “reserves the right to reclaim compute resources” if Anthropic’s AI “harms humanity.”
For now, the deal keeps both sides on the same side of the table. For Claude users, the most direct outcome is fewer interruptions and more room to work. For SpaceX, it locks in a major customer ahead of a widely anticipated IPO. And for the broader AI infrastructure race, it confirms that compute capacity has become just as competitive a front as model quality itself.
