Amazon is escalating its Anthropic wager with a new agreement that adds up to $25 billion to the $8 billion it had already committed, while locking in more than $100 billion of AWS-related spending from the startup over the next decade.
The structure is the real story. Amazon is not just writing a larger equity check. It is tying that capital to a 10-year infrastructure relationship that turns Anthropic’s need for compute into long-term demand for AWS chips, cloud capacity, and model-serving infrastructure. The latest package includes an immediate $5 billion investment, with up to another $20 billion tied to future milestones, bringing Amazon’s total Anthropic commitment to as much as $33 billion.
Anthropic said the agreement secures up to 5 gigawatts of AWS capacity to train and deploy Claude using Trainium2, Trainium3, Trainium4, and future generations of Amazon’s custom AI silicon. Capacity begins coming online this quarter, with nearly 1 gigawatt expected by the end of 2026. Amazon separately said significant Trainium3 capacity is expected this year.
The expansion comes as Anthropic tries to get ahead of infrastructure bottlenecks that are already showing up in the business. The company said last week that rising enterprise and developer demand had created “inevitable strain” on its systems, affecting reliability and performance.

Reuters, citing sources familiar with Anthropic’s projections, reported the company is forecasting about $14 billion in revenue over the next year.
Amazon is using the deal to press a broader point about Trainium. CEO Andy Jassy said Anthropic’s decision to run its large language models on AWS Trainium for the next decade reflects the progress Amazon has made on custom silicon. The tech giant also said the partnership will expand Anthropic’s use of AWS for both training and global inference, including deployments across Asia and Europe.
The agreement also reinforces Amazon’s emerging position as the infrastructure layer beneath competing frontier labs. In February 2026, Amazon and OpenAI announced a separate partnership under which Amazon committed up to $50 billion and OpenAI agreed to use 2 gigawatts of Trainium capacity.
