Amazon and OpenAI formalized a sweeping strategic partnership on Sunday, encompassing a $50 billion investment by Amazon and a cloud services agreement valued at $38 billion, according to announcements from both companies.
The agreement will spot Amazon Web Services (AWS) become the exclusive third-party cloud provider for OpenAI’s Frontier models, enabling organizations to build and deploy AI agents at scale. OpenAI will also leverage 2 gigawatts of AWS’s Trainium capacity to support its advanced workloads, including the Stateful Runtime Environment and Frontier platform. This marks OpenAI’s first contract with a major cloud infrastructure provider.
A core component of the partnership is the joint development of a Stateful Runtime Environment powered by OpenAI models, accessible through Amazon Bedrock. This environment is designed to provide developers with persistent context, memory, and access to compute resources, facilitating more complex and ongoing AI projects. The Stateful Runtime Environment will be optimized to run on AWS infrastructure and integrated with Amazon Bedrock AgentCore and other AWS services.
Amazon’s $50 billion investment in OpenAI will be delivered in two phases: an initial $15 billion investment, followed by an additional $35 billion contingent upon the fulfillment of certain unspecified conditions. The partnership aims to accelerate AI innovation for enterprises, startups, and consumers globally, with both companies developing customized models to power Amazon’s customer-facing applications.
The cloud services deal, finalized in November 2025, commits OpenAI to purchasing $38 billion worth of capacity from AWS. This agreement underscores Amazon’s position in the rapidly evolving generative AI landscape and its competition with other cloud providers in offering AI infrastructure and services.
As of Sunday, neither Amazon nor OpenAI had detailed the specific conditions tied to the remaining $35 billion of Amazon’s investment.
