The deal is Amazon’s second consecutive mega-round with a frontier AI lab, following a near-identical $50 billion investment in OpenAI two months ago. Anthropic’s annualised revenue has reached $30 billion. The arrangement locks Anthropic into AWS’s Trainium chips through Trainium4 and secures up to 5 gigawatts of compute capacity for Claude.
Amazon has agreed to invest up to $25 billion in Anthropic, the AI safety company behind the Claude family of models, as part of an expanded agreement that simultaneously locks in more than $100 billion of cloud spending by Anthropic on Amazon Web Services over the next decade.
Amazon is making an immediate investment of $5 billion, with up to $20 billion more tied to commercial milestones. This is on top of the $8 billion Amazon had already committed to Anthropic since 2023, bringing total potential Amazon investment to approximately $33 billion.
The structure of the deal is worth examining. Amazon is not writing a cheque for $25 billion outright; the bulk of the new capital is contingent on performance.

Simultaneously, Anthropic’s $100 billion spending commitment to AWS is not a payment but a procurement pledge, a commitment to buy cloud compute, custom AI chips, and infrastructure services from Amazon over ten years.
Amazon funds Anthropic, and Anthropic spends that capital on Amazon’s infrastructure. The same structure was used two months ago when Amazon invested $50 billion in OpenAI as part of a comparable $100 billion cloud commitment.
The compute at the centre of the agreement is Amazon’s Trainium chip line, its in-house alternative to Nvidia GPUs for AI training and inference. The deal covers current Trainium2, the forthcoming Trainium3, and Trainium4, which has not yet been released. It also includes tens of millions of Graviton CPU cores.
Anthropic secures up to 5 gigawatts of capacity to train and deploy its Claude models under the deal. Amazon said that significant Trainium2 capacity is coming online in the second quarter of 2026, with nearly one gigawatt of combined Trainium2 and Trainium3 expected by year-end.
The compute commitment is a direct response to what Anthropic describes as rapidly growing demand: the company’s annualised revenue has reached $30 billion, up from approximately $9 billion at the end of 2025.
The partnership also deepens how Anthropic’s models are distributed. AWS customers will now be able to access the full Claude Platform, Anthropic’s native product interface, directly through their existing AWS accounts, without separate credentials or billing.
This is a step beyond having Claude available through Amazon Bedrock, Amazon’s managed AI marketplace. Claude remains the only frontier model available across all three major cloud platforms: AWS Bedrock, Google Cloud Vertex AI, and Microsoft Azure Foundry.
The geopolitical backdrop matters to this deal. Anthropic is currently barred from Department of Defense contracts following a supply-chain risk designation that it is contesting in court.
That dispute sits alongside a broader AI policy environment in which the Trump administration has been simultaneously pressuring AI companies to loosen safety constraints and courting them for national security applications.
Dario Amodei, Anthropic’s CEO, has been navigating that tension publicly. The commercial momentum of the AWS deal, and the implicit validation of Anthropic’s infrastructure scale, is one answer to critics, including OpenAI, who suggested last week that Anthropic had made a strategic mistake by not securing enough compute.
In November 2025, Microsoft invested up to $5 billion in Anthropic as part of a separate deal in which Anthropic committed to purchasing $30 billion of Azure compute capacity. The AWS deal dwarfs that arrangement and firmly establishes Amazon as Anthropic’s primary infrastructure partner.
The initial investment in this round is priced at Anthropic’s latest valuation of $380 billion. Venture capital firms have reportedly been offering capital at valuations of $800 billion or more ahead of a potential IPO, though no such round has been announced.
