Amazon has agreed to invest up to $25 billion in Anthropic, on top of the $8 billion it has already poured into the AI startup, as part of an expanded deal for Anthropic to secure up to 5 gigawatts (GW) of capacity for training and deploying Claude.
In exchange, Anthropic committed to spending more than $100 billion on AWS technologies over the next ten years. The numbers are large enough to command attention, and what they reveal about the current state of the AI race is worth understanding.
What the Deal Actually Involves
Amazon is making an immediate investment of $5 billion, with up to $20 billion more tied to commercial milestones. Combined with the $8 billion Amazon had already committed to Anthropic since 2023, total potential Amazon investment reaches approximately $33 billion.
The structure of the deal is also noteworthy as the bulk of the new capital is contingent on performance. Meanwhile, 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 the next decade.
As such, the commitment covers current and future generations of Trainium, Amazon’s custom silicon, as well as tens of millions of Graviton cores. Anthropic will secure up to 5 gigawatts of capacity, including significant Trainium3 capacity expected to come online this year.
Why Anthropic Needed This
Anthropic’s run-rate revenue has hit $30 billion, up from roughly $9 billion at the end of 2025. More than 1,000 business customers now spend more than $1 million annually, a figure that doubled in less than two months.
And so this kind of growth has come with pressure. According to the AI safety company, surging consumer demand has strained their systems, impacting reliability and performance for free, Pro, Max, and Team users during peak hours. The AWS deal is directly aimed at fixing that, with Anthropic saying the expanded capacity will deliver meaningful compute within three months and nearly 1 gigawatt in total before the end of 2026.
Dario Amodei, Anthropic’s CEO, said that Claude is increasingly essential to how users work and that the company needs to build the infrastructure to keep pace with rapidly growing demand, including the more than 100,000 customers already building on AWS.
What It Says About the Broader AI Arms Race
The deal echoes an agreement Amazon struck with OpenAI just two months ago, when it joined a $122 billion funding round, contributing $50 billion, that valued the ChatGPT maker at $820 billion. That deal was also structured partly as cloud infrastructure services rather than straight cash. Amazon is running the same approach with both leading AI labs.
Claude remains the only frontier model available across all three major cloud platforms, AWS Bedrock, Google Cloud Vertex AI, and Microsoft Azure Foundry. That cross-platform reach is a competitive distinction that neither OpenAI nor Google’s Gemini currently holds in the same way.
Anthropic’s valuation now stands at $380 billion following its Series G round in February 2026, with venture capital firms reportedly circling with offers that would push that figure to $850 billion or more, ahead of a potential IPO.
As such, this $100 billion figure is not a single payment or a guarantee. It is a bet, structured over a decade, on who builds the infrastructure that powers AI at scale.
