Amazon and Anthropic have announced a major expansion of their strategic partnership, deepening collaboration across artificial intelligence infrastructure, model development, and cloud services.
The companies stated that since 2023 they have worked together to accelerate generative AI adoption across industries, enabling customers to build and scale AI applications. More than 100,000 customers now run Anthropic’s Claude models on AWS, making Claude one of the most widely used model families on Amazon Bedrock. Both companies are also collaborating on Project Rainier, a large-scale AI compute cluster designed to support advanced model training and deployment.
Under the expanded agreement, Anthropic has committed to spending more than $100 billion over the next decade on AWS technologies, including current and future generations of Amazon’s custom AI chips such as Trainium and Graviton processors. The partnership will also provide up to 5 gigawatts of compute capacity to support training and running advanced AI models, with significant new Trainium3 capacity expected to come online this year. The collaboration further expands international AI inference capacity across Asia and Europe to meet growing global demand for Claude models.
The agreement also covers future chip generations, including Trainium2, Trainium3, Trainium4, and beyond, as Anthropic continues to scale its AI workloads using AWS infrastructure. The companies noted that AWS’s Trainium and Graviton technologies already support more than 100,000 customers and power most inference workloads on Amazon Bedrock.
A new integration will also allow AWS customers to access Anthropic’s Claude platform directly through their AWS accounts, using existing credentials, security controls, and billing systems. Customers will be able to choose between Claude on Amazon Bedrock or the Claude-native experience on AWS depending on their needs.
As part of the expanded relationship, Amazon will also invest $5 billion in Anthropic, with an additional $20 billion planned subject to future commercial milestones. This builds on a previous $8 billion investment.
“Our custom AI silicon offers high performance at significantly lower cost for customers, which is why it’s in such hot demand. 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, as we continue delivering the technology and infrastructure our customers need to build with generative AI.”
– Andy Jassy, CEO, Amazon
“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. Our collaboration with Amazon will allow us to continue advancing AI research while delivering Claude to our customers, including the more than 100,000 building on AWS.”
– Dario Amodei, CEO and Co-founder, Anthropic
The companies highlighted several key joint initiatives, including deep collaboration on custom silicon development with Amazon’s Annapurna Labs, where Anthropic provides direct feedback to shape future AI chip designs. Another major initiative, Project Rainier, is described as one of the world’s largest AI compute clusters, featuring nearly half a million Trainium2 chips and supporting large-scale training and deployment of Claude models.
Amazon and Anthropic also pointed to growing enterprise adoption of Claude across industries. Examples include Lyft using Claude via Amazon Bedrock to automate customer support and reduce resolution times by 87 percent, and Pfizer leveraging Claude to streamline research workflows, saving thousands of scientist hours annually while reducing infrastructure costs.
Both companies reaffirmed their commitment to making AWS the primary platform for Anthropic’s large-scale model training and deployment, while also enabling Amazon teams to use Claude models to improve services across its broader ecosystem.
