Amazon is investing $50 billion in OpenAI as part of its latest multi-year strategic partnership to build next-generation artificial intelligence infrastructure and enterprise tools. The deal also positions Amazon as the largest backer in OpenAI’s latest $110 billion funding round, which includes a $30 billion investment from SoftBank, $30 billion from Nvidia.
Amazon will be investing in OpenAI in phases, beginning with an initial $15 billion infusion, followed by a further $35 billion subject to certain conditions. The announcement comes just weeks after Amazon completed 30,000 layoffs across multiple divisions, in a strategic shift aimed at reducing bureaucracy, flattening organisational structures, and reallocating resources towards Artificial Intelligence (AI).
The latest funding round, which includes big backers like Amazon, SoftBank and Nvidia, reportedly values OpenAI at a pre-money valuation of $730 billion, a sharp rise from its $300 billion valuation in March 2025. This jump in investment also makes the raise one of the largest private technology funding rounds to date, with other major backers including Nvidia and SoftBank, each pledging $30 billion.
While announcing the partnership, Amazon CEO Andy Jassy praised OpenAI as a highly talented team with strong products, adding that he sees it emerging as one of the big winners in the AI race.
“We’re excited about our investment in OpenAI — it’s an extremely talented team with great products, IP, and vision for how they can continue to serve customers and enterprises. We think they’ll be one of the big winners in AI, we can help them grow, and we believe we’ll earn a strong return for Amazon over the long term,” he wrote on X.
Amazon and OpenAI plans with $50 billion investment
The partnership between OpenAI and Amazon is not just about handing over the capital.
One of the central investments is in infrastructure. As part of this billion-dollar partnership, OpenAI and Amazon Web Services (AWS) will significantly expand their existing multi-year arrangement, increasing infrastructure commitments by $100 billion over eight years. Under this expanded agreement, OpenAI has committed to consuming approximately 2 gigawatts of AWS Trainium compute capacity to support training and inference workloads for advanced AI systems.
According to OpenAI, this long-term commitment will help lower costs and improve the efficiency of producing AI at scale. It will span both current Trainium3 chips and next-generation Trainium4 silicon, which is expected to begin delivery in 2027 and offer substantial performance gains, including higher compute capability and greater memory bandwidth.
Another key focus of the partnership is the joint development of a Stateful Runtime Environment powered by OpenAI models. The new system will be available to AWS customers through Amazon Bedrock and is designed to support context-aware AI agents that can remember prior interactions, access tools and data sources, and operate across complex workflows.
In addition, OpenAI has announced that AWS will become the exclusive third-party cloud distribution provider for OpenAI Frontier, the company’s enterprise AI platform that enables organisations to build, deploy and manage teams of AI agents with built-in governance and enterprise-grade security.
Meanwhile, the partnership also includes product-level integration. OpenAI and Amazon will collaborate on developing customised AI models tailored for Amazon’s customer-facing applications. These models will be made available to Amazon developers and are expected to complement the company’s existing Nova family of models, offering additional flexibility for building AI-powered services and agents.
