Anthropic secures $5 billion from Amazon and commits to $100 billion AWS spending over 10 years

Amazon announced on Monday that it is investing $5 billion in Anthropic, expanding its previous stake in the AI company. Combined with earlier investments, Amazon's total commitment to Anthropic now stands at $13 billion. In exchange, Anthropic has agreed to commit more than $100 billion in spending on AWS services over the next decade, with access to up to 5 gigawatts of new computing capacity dedicated to training and operating Claude.

The financial structure reflects a hybrid model: rather than a straightforward equity investment, the agreement bundled capital with infrastructure commitments. A comparable arrangement was reached between Amazon and OpenAI approximately two months earlier, when Amazon contributed $50 billion to a $110 billion funding round that valued OpenAI at $730 billion on a pre-money basis.

The infrastructure component of the Anthropic deal centers on Amazon's proprietary silicon. Anthropic will gain access to Trainium2, Trainium3, and Trainium4 chips—Amazon's AI accelerators positioned as alternatives to Nvidia hardware—as well as Graviton processors designed for lower-power applications. Notably, Trainium4 chips remain unavailable at present, though Anthropic has secured the right to purchase capacity on future Amazon chips upon release. The most recent generation, Trainium3, launched in December 2025.
