OpenAI and Amazon have entered a multi year partnership that combines cloud infrastructure, custom silicon, and AI software, backed by a $50 billion investment from the retail giant. The agreement expands OpenAI’s use of AWS infrastructure and includes new enterprise AI tools, including a stateful runtime environment and the Frontier platform, to AWS customers.
Amazon will invest $50 billion in OpenAI, beginning with $15 billion and followed by another $35 billion when certain conditions are met. The companies say the partnership is focused on scaling AI systems for enterprises, startups, and consumer applications.

A central part of the deal is a jointly developed Stateful Runtime Environment powered by OpenAI models. It will be offered through Amazon Bedrock and integrated with AWS infrastructure.
Stateful runtime environments allow models to retain context across sessions, access memory and compute resources, and interact with external tools and data sources. Instead of responding to isolated prompts, AI systems can manage ongoing workflows and longer term projects.
The environment will be optimized for AWS infrastructure and connected to Amazon Bedrock AgentCore. That will let AI agents operate alongside other applications running in AWS without separate infrastructure management. The Stateful Runtime Environment is expected to launch in the next few months.
AWS and OpenAI
Amazon Web Services will also become the exclusive third party cloud distribution provider for OpenAI Frontier. Frontier is OpenAI’s enterprise platform for building and managing teams of AI agents that operate across business systems.
Frontier includes shared context, governance controls, and enterprise grade security features. Organizations can deploy AI agents into production systems without managing underlying infrastructure directly.
The partnership also expands an existing infrastructure agreement between OpenAI and AWS. The companies are adding $100 billion over eight years to a prior $38 billion multi year arrangement.
As part of that expansion, OpenAI has committed to consume about 2 gigawatts of Trainium capacity through AWS infrastructure. The capacity will support workloads tied to the Stateful Runtime Environment, Frontier, and other advanced AI systems.
The agreement spans both Trainium3 and next generation Trainium4 chips. Trainium4 is expected to begin delivery in 2027 and is projected to offer higher FP4 compute performance, expanded memory bandwidth, and increased high bandwidth memory capacity.
Under the structure of the agreement, OpenAI secures long term compute access while working with AWS to deploy purpose built silicon alongside its broader infrastructure stack. Enterprises using AWS can access AI services without directly managing large scale training hardware.
In addition to infrastructure and enterprise tooling, OpenAI and Amazon plan to develop customized AI models for Amazon’s customer facing applications. These models will be available to Amazon developers building AI driven products and agents.
They will complement Amazon’s existing model lineup, including the Nova family, and be tailored for direct integration into Amazon services.
“OpenAI and Amazon share a belief that AI should show up in ways that are practical and genuinely useful for people,” said Sam Altman, co-founder and CEO of OpenAI. ”Combining OpenAI’s models with Amazon’s infrastructure and global reach helps us put powerful AI into the hands of businesses and users at real scale.”
“We have lots of developers and companies eager to run services powered by OpenAI models on AWS, and our unique collaboration with OpenAI to provide stateful runtime environments will change what’s possible for customers building AI apps and agents,” said Andy Jassy, President and CEO of Amazon. “We continue to be impressed with what OpenAI is building, and we’re excited not only about their choosing to go big on our custom AI silicon (Trainium), but also our opportunity to invest in the company and partnership over the long-term.”
