Amazon–Anthropic AI pact

Amazon and Anthropic tightened their alliance on April 20, with Amazon committing up to $25 billion more and Anthropic locking in a decade of Amazon cloud capacity. (aboutamazon.com) Amazon said it will invest $5 billion immediately and up to $20 billion more later. Anthropic said it will spend more than $100 billion on Amazon Web Services technologies over the next 10 years. (aboutamazon.com) The cloud side of the deal is unusually large: Anthropic said it secured up to 5 gigawatts of computing capacity to train and run Claude. The agreement covers Amazon’s Trainium artificial-intelligence chips, Graviton central processors, and future chip generations. (anthropic.com) Anthropic said new Trainium2 capacity will come online in the first half of 2026, and nearly 1 gigawatt of Trainium2 and Trainium3 capacity is expected by the end of 2026. Amazon said significant Trainium3 capacity is expected to come online this year. (anthropic.com) (aboutamazon.com) The pact shows how the artificial-intelligence race is shifting from model launches to power, chips, and data-center space. Anthropic said the new agreement will support both training new Claude models and inference, the step where a trained model answers user requests. (anthropic.com) It also ties Anthropic more tightly to Amazon Web Services after earlier rounds of funding. Anthropic said Amazon’s new commitment builds on $8 billion already invested, and Amazon Web Services remains its primary training and cloud provider for mission-critical workloads. (anthropic.com) (cnbc.com) Amazon and Anthropic have been working together since 2023. Amazon completed a $4 billion investment in March 2024, then announced another $4 billion in November 2024 that made Amazon Web Services Anthropic’s primary cloud and training partner. (aboutamazon.com) (cnbc.com) Amazon said more than 100,000 customers already run Claude models on Amazon Bedrock, its managed artificial-intelligence service. Anthropic said the full Claude Platform will also be available directly inside Amazon Web Services accounts, with the same billing and access controls customers already use. (aboutamazon.com) (anthropic.com) Anthropic said Claude will remain available on Google Cloud and Microsoft Azure even as Amazon becomes the main infrastructure partner. Amazon, for its part, is using the deal to push Trainium as a lower-cost alternative to the graphics processors that dominate artificial-intelligence computing. (anthropic.com) For now, the clearest number in the deal is not the equity check but the cloud bill: more than $100 billion over 10 years, in exchange for the chips and power Anthropic says it needs to keep Claude growing.
