Amazon Will Invest Up to $25 Billion More in Anthropic as AI Demand Surges

In brief Amazon announced up to $25 billion in new investment in AI startup Anthropic, with $5 billion committed immediately. Anthropic commits to spending $100 billion on AWS infrastructure over the next 10 years. The AI company secured 5 gigawatts of computing capacity on Amazon's custom Trainium chips. Amazon.com announced an expanded partnership with AI startup Anthropic late Monday, committing up to $25 billion in new investment that includes $5 billion immediately and up to $20 billion more tied to commercial milestones. The deal adds to Amazon's previous $8 billion investment in Anthropic, bringing its total potential stake to $33 billion. In return, Anthropic committed to spending over $100 billion on Amazon Web Services technologies through 2036. The AI company will access up to 5 gigawatts of computing capacity for training and deploying its Claude AI models on Amazon's custom silicon. Anthropic currently uses 1 million AWS Trainium2 chips, and will gain additional Trainium2 and Trainium3 capacity as Amazon brings 1 gigawatt online by the end of 2026. “Our custom AI silicon offers high performance at significantly lower cost for customers, which is why it’s in such hot demand," said Amazon CEO Andy Jassy, in a statement. "Anthropic's commitment to run its large language models on AWS Trainium for the next decade reflects the progress we've made together on custom silicon, as we continue delivering the technology and infrastructure our customers need to build with generative AI.”  Amazon's latest AI partnership follows its $50 billion contribution to OpenAI's $110 billion funding round two months ago, a deal that valued OpenAI at $730 billion pre-money. The e-commerce giant expects to spend $200 billion on capital expenditures this year, with the majority allocated to AI infrastructure development. Founded in 2021 by former OpenAI researchers and executives, Anthropic has grown its annualized revenue to over $30 billion. The company's Claude AI models compete directly with OpenAI's GPT series and Google's Gemini. Amazon's custom chip roadmap includes the Trainium3 processors released in December 2025 and the upcoming Trainium4, which AWS says will deliver 2 exaflops of performance for FP4 data processing.
