Amazon will invest up to $25 billion in Anthropic, the companies announced Monday. The deal includes $5 billion immediately at Anthropic’s $380 billion valuation, with an additional $20 billion tied to commercial milestones. This brings Amazon’s total investment in the Claude maker to as much as $33 billion.

The capital is one side of a broader infrastructure lock-in. Anthropic is committing more than $100 billion in AWS spending over the next decade, spanning current and future generations of Amazon’s custom Trainium chips through Trainium4 and beyond, plus tens of millions of Graviton CPU cores.

5 Gigawatts of Capacity

Anthropic has secured up to 5 gigawatts of capacity for training and deploying Claude. Significant Trainium2 capacity is coming online in Q2 2026, with nearly 1 gigawatt total of Trainium2 and Trainium3 expected before year-end, according to Anthropic’s announcement. The company currently uses over one million Trainium2 chips.

The deal also includes international inference expansion in Asia and Europe to serve Claude’s growing customer base outside the U.S.

“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,” Amazon CEO Andy Jassy said in a statement.

Revenue and Demand Context

Anthropic disclosed that its annualized revenue run-rate has surpassed $30 billion, up from approximately $9 billion at the end of 2025, according to the company’s blog post. Over 100,000 customers now run Claude on Amazon Bedrock.

“Our users tell us Claude is increasingly essential to how they work, and we need to build the infrastructure to keep pace with rapidly growing demand,” CEO Dario Amodei said. Anthropic acknowledged that rapid consumer growth across free, Pro, and Max tiers has strained reliability and performance during peak hours.

Claude Platform on AWS

A new integration will make Anthropic’s full Claude Platform available directly within AWS. Customers access the native Claude console through their existing AWS account, same controls, same billing, no additional credentials. Claude Platform on AWS launched in private beta on April 20.

Claude remains the only frontier AI model available on all three major cloud platforms: AWS (Bedrock), Google Cloud (Vertex AI), and Microsoft Azure (Foundry).

The Hyperscaler AI Arms Race

The timing is notable. Amazon agreed to invest up to $50 billion in OpenAI just two months ago, according to CNBC. Amazon expects to spend roughly $200 billion on capital expenditures this year, most of it on AI infrastructure.

Anthropic has been building compute relationships across multiple providers. Microsoft invested up to $5 billion in November, with Anthropic committing $30 billion in Azure compute. Earlier this month, Anthropic expanded capacity partnerships with Google and Broadcom for multiple additional gigawatts.

OpenAI executives have publicly criticized Anthropic for making a “strategic misstep to not acquire enough compute,” according to an internal memo reported by CNBC. Monday’s announcement is Anthropic’s direct answer: a decade-long infrastructure commitment that ties its future to Amazon’s custom silicon roadmap while maintaining multi-cloud availability across all three hyperscalers.
