Anthropic makes a deal with Nvidia and Microsoft. Anthropic will be on Azure to supplement their deals with Google and Amazon, and Nvidia and Microsoft will invest $10 billion and $5 billion respectively. Anthropic is committing to purchasing $30 billion of Azure compute and contracting additional capacity to one gigawatt. Microsoft is committing to continuing access to Claude in their Copilot offerings.
This is a big deal. Previously Anthropic was rather conspicuously avoiding Nvidia, and now they will collaborate on design and engineering, call it a ‘tech stack’ if you will, while also noticing Anthropic seems happy to have three distinct tech stacks with Nvidia/Microsoft, Google and Amazon. They have deals with everyone, and everyone is on their cap table. A valuation for this raise is not given, the previous round was $13 billion at a $183 billion valuation in September.
News sources seem to estimate the new valuation “in the range of $350 billion”: https://www.cnbc.com/2025/11/18/anthropic-ai-azure-microsoft-nvidia.html
