Anthropic expanding to Colossus2 GB200

Anthropic has confirmed a string of large infrastructure deals in 2026, but there is no public company statement as of Friday, May 22, 2026, backing social-media claims that it is expanding to “Colossus2” or deploying Nvidia GB200 chips today. Anthropic’s newsroom shows no May 22 announcement on that topic, and the company’s most recent disclosed compute expansions point elsewhere. (cnbc.com) May 6 is the clearest recent marker. CNBC reported that Anthropic said it had signed a deal with SpaceX to use all of the compute capacity at Colossus 1 in Memphis, Tennessee. (anthropic.com) Bloomberg separately reported that the agreement would give Anthropic access to more than 300 megawatts of computing capacity and help it meet demand for Claude. April 6 is the other confirmed expansion. Anthropic said it had signed a new agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity expected to come online starting in 2027. (anthropic.com) CFO Krishna Rao said the deal was part of a “disciplined approach to scaling infrastructure” for customer demand and future Claude models. ### Where does the “Colossus2 GB200” claim stand? No primary-source confirmation has surfaced. A search across Anthropic’s newsroom, Microsoft’s official blog, Nvidia’s data-center materials and major news outlets did not produce a May 22 announcement tying Anthropic to a site called “Colossus2.” (cnbc.com) Nvidia does market the GB200 NVL72 system as a rack-scale Blackwell platform for AI training and inference. But Nvidia’s product page is a specification page, not evidence that Anthropic has deployed that hardware at a named facility. (anthropic.com) ### What has Anthropic actually said about compute this year? November 18, 2025 remains the biggest Microsoft-linked infrastructure disclosure. Microsoft said Anthropic would scale Claude on Azure powered by Nvidia, and Anthropic said Microsoft and Nvidia were committing to invest up to $5 billion and up to $10 billion, respectively, as part of broader partnerships. (anthropic.com) Anthropic also said Amazon remained its primary cloud provider and training partner. (nvidia.com) November 12, 2025 is the company’s other major disclosed buildout. Anthropic said it would invest $50 billion in American computing infrastructure with Fluidstack, with data centers in Texas and New York custom-built for its workloads. ### What about the Microsoft chip-deal talk? No verified May 22 report in the sourced material confirms new talks between Microsoft and Anthropic for a separate AI chip deal. The closest confirmed Microsoft-Anthropic tie-up is the November 2025 partnership covering Azure capacity, Claude distribution across Microsoft Copilot products and Microsoft’s planned investment of up to $5 billion. (blogs.microsoft.com) Because no primary filing, company post or on-record report was found for a new chip agreement, that claim remains unverified. (anthropic.com) ### Are Series H funding reports confirmed? February 12, 2026 is Anthropic’s latest confirmed funding announcement. The company said it raised $30 billion in Series G at a $380 billion post-money valuation. (blogs.microsoft.com) April 29 brought a separate report from Bloomberg that Anthropic had begun weighing a fresh funding round at a valuation of more than $900 billion, citing people familiar with the matter. Bloomberg’s excerpt did not describe that financing as completed, and Anthropic has not posted a Series H announcement in its newsroom. (blogs.microsoft.com) ### What should readers watch next? Anthropic’s official newsroom is the first place a new infrastructure or funding announcement would likely appear. (anthropic.com) Microsoft’s corporate blog is also relevant because it carried the companies’ November 2025 partnership announcement. Nvidia’s GB200 product pages can confirm hardware specifications, but not customer deployments unless Nvidia or the customer names them directly. Until Anthropic, Microsoft, Nvidia or a major outlet publishes an on-record report, the May 22 “Colossus2 GB200” claim should be treated as unconfirmed. (bloomberg.com) (nvidia.com) (anthropic.com)
