Amazon commits $25B to Anthropic to launch Claude Platform

Anthropic said on April 20 that Amazon had agreed to invest up to $25 billion more in the artificial intelligence company as part of a broader infrastructure deal centered on Claude. The agreement adds to the $8 billion Amazon had already invested and pairs the new capital with a long-term commitment by Anthropic to spend more than $100 billion on Amazon Web Services technologies over 10 years. AWS said on May 11 that Claude Platform on AWS is now generally available, giving customers direct access to Anthropic's native Claude Platform through existing AWS accounts. Anthropic said the setup keeps AWS authentication, billing and commitment retirement in place while exposing the same APIs, console and beta features available on Anthropic's own platform. (anthropic.com) The two announcements are linked but distinct. The investment and infrastructure agreement was disclosed on April 20, while the product launch for Claude Platform on AWS was announced on May 11. Social posts describing both as a single May 14 event compress a timeline that unfolded over several weeks. ### When did Amazon actually commit the $25 billion? Anthropic dated the expanded agreement with Amazon to April 20, 2026. (aws.amazon.com) In that announcement, the company said Amazon was investing $5 billion immediately, with up to another $20 billion available later, bringing the new commitment to as much as $25 billion. CNBC reported the same day that the additional funding was tied to commercial milestones and valued the initial $5 billion tranche at Anthropic's latest $380 billion valuation. (anthropic.com) That report also said the new commitment would bring Amazon's total potential investment in Anthropic to $33 billion including prior funding. ### What exactly is Claude Platform on AWS? (anthropic.com) AWS said the service gives customers access to Anthropic's native Claude Platform experience without separate Anthropic accounts, contracts or billing relationships. Anthropic said customers can use the same AWS credentials, IAM policies and invoicing they already use for other AWS services. The May 11 launch goes beyond model access in Amazon Bedrock. (cnbc.com) AWS said Claude Platform on AWS includes the native Claude API, console and early-access beta features such as managed agents, code execution, web search, web fetch, prompt caching, citations and batch processing. Anthropic said Bedrock remains available separately, where AWS acts as the data processor. (aws.amazon.com) ### How much infrastructure is Anthropic committing to AWS? Anthropic said the April 20 agreement secures up to 5 gigawatts of capacity for training and deploying Claude and commits the company to spend more than $100 billion on AWS technologies over the next decade. The company said the commitment spans Graviton processors and Trainium chips from Trainium2 through Trainium4, with options on future generations of Amazon silicon. (aws.amazon.com) The same announcement said significant Trainium2 capacity would come online in the second quarter of 2026 and that nearly 1 gigawatt of Trainium2 and Trainium3 capacity is expected to be online by the end of 2026. Andy Jassy, Amazon's chief executive, said Anthropic's decision to run its large language models on AWS Trainium for the next decade reflected progress on Amazon's custom AI silicon.

Anthropic said on April 6 that it had also signed a separate agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity expected to come online starting in 2027. The company said that deal would expand compute infrastructure for Claude, with most of the new capacity sited in the United States. (anthropic.com) Anthropic did not say in that announcement that it had committed $200 billion to Google Cloud. It said Amazon remains its primary cloud provider and training partner, even as it continues to train and run Claude on AWS Trainium, Google TPUs and Nvidia GPUs. ### What about the reports of $200 billion in spending? CNBC reported on April 20 that Amazon said in February it expected to spend roughly $200 billion in capital expenditures in 2026, with most of that going to AI infrastructure. (anthropic.com) That figure refers to Amazon's own expected capital spending, not to a disclosed Anthropic commitment to Google Cloud. AWS said Claude Platform on AWS is available across commercial regions in North America, Europe and Asia Pacific, including Northern Virginia, Ohio, Oregon, Dublin, London, Frankfurt, Tokyo, Seoul and Sydney. Anthropic said customers can request access through AWS accounts, while the April 20 infrastructure agreement points to added Trainium capacity coming online through the rest of 2026.
