Anthropic Faces Growing Pains Amid Rapid Growth and IPO Speculation

Anthropic has announced a deal to utilize the entire compute capacity of SpaceX's Colossus 1 data center. The partnership, intended to address recent customer usage limits, provides access to over 300 megawatts of new capacity featuring more than 220,000 Nvidia GPUs. The AI lab also expressed interest in collaborating with SpaceX on future orbital compute projects.

Facts First

  • Anthropic will use all capacity of SpaceX's Colossus 1 data center, located in Memphis, Tennessee.
  • The deal provides over 300 megawatts of new compute power, including more than 220,000 Nvidia H100, H200, and GB200 GPUs.
  • Anthropic implemented the deal to increase usage limits for its Pro and Max plan subscribers, following a spike in demand.
  • SpaceX's xAI lab will continue operating separately using the Colossus 2 supercomputer.
  • Anthropic expressed interest in partnering with SpaceX to develop multiple gigawatts of orbital AI compute capacity.

What Happened

Anthropic announced a deal with SpaceX at its Code with Claude developer conference on Wednesday in San Francisco. The agreement involves Anthropic utilizing the entire compute capacity of SpaceX's Colossus 1 data center within the month. The capacity amounts to more than 300 megawatts and includes over 220,000 Nvidia GPUs, featuring dense deployments of H100, H200, and next-generation GB200 accelerators. Anthropic CEO Dario Amodei stated the deal is intended to increase usage limits for the company's Pro and Max plan subscribers, following recent difficulties with compute due to a demand spike.

Why this Matters to You

If you are a developer or business using Anthropic's AI models, this deal may lead to more reliable access and higher usage limits. The company has already doubled Claude Code's five-hour window limits for Pro and Max subscribers and removed peak-hours limit reductions for those accounts. For users of the Opus model, API limits were raised earlier in May. The significant new compute capacity could help stabilize service and support Anthropic's reported rapid growth, which the company says saw '80x growth per year in revenue and usage' for the first quarter of 2026.

What's Next

SpaceX is expected to file its S-1 for an initial public offering (IPO) next month, in June. The partnership with Anthropic could extend beyond the current data center deal, as SpaceX stated Anthropic expressed interest in partnering to develop multiple gigawatts of orbital AI compute capacity. Elon Musk, who recently met with senior Anthropic leaders and stated he 'was impressed,' is separately involved in a lawsuit against OpenAI.

Perspectives

“
Strategic Analysts argue that the deal transforms idle compute assets into high-margin revenue streams, potentially preventing massive write-downs before a SpaceX IPO while serving as a tactical move against Sam Altman.
“
Market Researchers suggest that the partnership is driven by a 'the enemy of my enemy is my friend' logic, where Musk and Anthropic's leadership align to counter Sam Altman.
“
Industry Experts point to Musk's history of over-investing in infrastructure, noting that previous capacity like 'xAI's Colossus 1' exceeded actual user demand.
“
Skeptics note that the deal contradicts Musk's previous public criticisms of Anthropic and suggest he would not share capacity if he were facing his own compute shortages.
“
Infrastructure Critics contend that relying on orbital data centers is an unproven solution to the growing limitations of terrestrial power, land, and cooling for AI training.
