Amazon is set to invest up to $25 billion in Anthropic, the AI safety company behind the Claude models, under a new agreement which secures over $100 billion of cloud spending by Anthropic on Amazon Web Services over the next decade. Initially, Amazon will inject $5 billion, with an additional $20 billion contingent upon meeting commercial targets, adding to the $8 billion already pledged since 2023, totaling approximately $33 billion in potential investment. The deal is structured around performance, not as a direct $25 billion payment. Anthropic’s $100 billion AWS commitment is a purchase pledge for Amazon’s cloud services and AI chips over ten years. Amazon’s funds for Anthropic are spent back on Amazon’s infrastructure, employing a similar approach as in Amazon’s $50 billion investment in OpenAI.
The agreement utilizes Amazon’s Trainium chips, including Trainium2, Trainium3, and Trainium4, plus Graviton CPU cores, granting Anthropic up to 5 gigawatts to train and deploy its Claude models. Amazon will bring significant Trainium2 capacity online by the second quarter of 2026, with nearly one gigawatt of Trainium2 and Trainium3 expected by year-end. Anthropic’s annual revenue has surged to $30 billion. The deal expands access to Anthropic’s Claude Platform directly through AWS accounts, beyond its availability on Amazon Bedrock, widening Anthropic’s distribution across AWS Bedrock, Google Cloud Vertex AI, and Microsoft Azure Foundry.
Currently, Anthropic is barred from Department of Defense contracts due to a contested supply-chain risk designation, amidst a broader AI policy framework under the Trump administration. Anthropic’s CEO Dario Amodei is navigating these tensions, rebutting critics, including OpenAI, regarding Anthropic’s compute resources. In 2025, Microsoft invested up to $5 billion in a separate deal with Anthropic, who committed to using $30 billion of Azure compute capacity. The AWS agreement exceeds this and cements Amazon as Anthropic’s primary infrastructure ally. This round is valued at Anthropic’s $380 billion valuation, with venture capital rumblings suggesting valuations of $800 billion or more ahead of potentially going public.
