OpenAI has raised $110 billion in new funding at a $730 billion pre-money valuation, as it seeks to scale infrastructure and products to meet rising global demand for AI.
The round includes $30 billion each from NVIDIA and SoftBank Group Corp, and $50 billion from Amazon, which will be deployed in two tranches — $15 billion upfront and $35 billion later, subject to certain conditions. Additional financial investors are expected to join as the round progresses.
OpenAI also announced a multi-year strategic partnership with Amazon and expanded collaboration with NVIDIA to secure next-generation inference and training capacity.
The company said the funding will support investment in compute, distribution, and capital to expand access to its products across consumers, developers, and enterprises.
“SoftBank, NVIDIA, and Amazon are long-term partners who share our ambition to turn real scientific progress into systems that deliver meaningful benefits for people at global scale. Building AI that works for everyone will require deep collaboration across the stack, and we’re excited to do this together,” said Sam Altman, co-founder and CEO of OpenAI.
Under the NVIDIA agreement, OpenAI will use 3 gigawatts (GW) of dedicated inference capacity and 2 GW of training capacity on Vera Rubin systems. This builds on Hopper and Blackwell systems already in operation across Microsoft, Oracle Cloud Infrastructure (OCI), and CoreWeave.
Amazon X OpenAI
The Amazon partnership is intended to accelerate AI deployment for enterprises, startups, and consumers. The companies said the collaboration will deepen infrastructure integration and expand global reach.
The companies will co-create a Stateful Runtime Environment powered by OpenAI models, which will be available on Amazon Bedrock for AWS customers building generative AI applications and agents.
“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.
As part of the agreement, Amazon Web Services (AWS) will become the exclusive third-party cloud distribution provider for OpenAI Frontier, the company’s enterprise platform for building and managing AI agent teams.
OpenAI will also consume approximately 2 gigawatts of Trainium capacity through AWS infrastructure under an expanded compute agreement. The companies are expanding their existing $38 billion multi-year agreement by an additional $100 billion over eight years.
The commitment spans Trainium3 and next-generation Trainium4 chips. Trainium4, expected to begin delivery in 2027, will offer higher FP4 compute performance, expanded memory bandwidth and increased high-bandwidth memory capacity to support large-scale AI workloads.
The companies said the structure secures long-term compute capacity for OpenAI while enabling enterprises to access AI capabilities through AWS infrastructure.
OpenAI said demand for its products has increased across segments. ChatGPT has more than 900 million weekly active users and over 50 million consumer subscribers.
More than 9 million paying business users rely on ChatGPT for work, according to the company. Enterprises, startups, and governments are building on the OpenAI platform across engineering, support, finance, sales, and operations. OpenAI said its Frontier platform helps enterprises build and manage AI systems for workplace use.
Codex, OpenAI’s software-focused product, has 1.6 million weekly users, more than triple the number at the start of the year. The company said users are building and shipping software that previously required engineering teams.
The latest valuation also increases the value of the OpenAI Foundation’s stake in OpenAI Group to over $180 billion.
OpenAI said the new capital and partnerships will help it train and deploy frontier models at global scale as AI systems move from research into daily use.
Nothing Changes With Microsoft
Microsoft said its partnership with OpenAI remains unchanged following OpenAI’s latest funding announcements and new collaborations, including a partnership with Amazon.
“Nothing about today’s announcements in any way changes the terms of the Microsoft and OpenAI relationship that have been previously shared in our joint blog in October 2025,” Microsoft said in a statement.
Microsoft said the partnership “remains strong and central,” adding that both companies continue to work together across research, engineering and product development.
The company clarified that its intellectual property arrangement with OpenAI remains intact. “Microsoft maintains its exclusive license and access to intellectual property across OpenAI models and products,” it said.
