OpenAI (OPENAI) confirmed on Friday that it has raised an astonishing $110B in its latest funding round, with $50B coming from Amazon (AMZN) and $30B apiece from Nvidia (NVDA) and SoftBank (SFTBY).
“Today we’re announcing $110B in new investment at a $730B pre-money valuation. This includes $30B from SoftBank, $30B from NVIDIA, and $50B from Amazon,” OpenAI said in a statement. “We’ve also signed a strategic partnership with Amazon and secured next generation inference compute with NVIDIA. Additional financial investors are expected to join as the round progresses.”
OpenAI details
OpenAI provided some details on its business and said it had more than 900M weekly active users, including more than 50M paying consumer subscribers and more than 9M paying business users.
“Subscriber momentum accelerated meaningfully to start the year, with January and February on track to be the largest months for new subscribers in our history,” OpenAI added.
OpenAI explained that the tech space has moved into a new phase where AI moves from research into daily use at scale and that the winners will be defined as to which companies “can scale infrastructure fast enough to meet demand, and turn that capacity into products people rely on.”
As part of the new funding round, OpenAI said the value of the OpenAI Foundation’s stake in OpenAI Group is now over $180B.
Amazon
As part of the funding round, OpenAI and Amazon signed a deal to have Amazon Web Services be the “exclusive third-party cloud distribution provider for OpenAI Frontier, which enables organizations to build, deploy, and manage teams of AI agents,” OpenAI said in a separate statement.
The two companies will expand their previous $38B deal by $100B over 8 years, OpenAI added. As part of that, AWS and OpenAI will co-create a Stateful Runtime Environment powered by OpenAI models, available on Amazon Bedrock for AWS customers.
OpenAI will also consume 2 gigawatts of Trainium capacity through AWS infrastructure, and they will develop customized models to power Amazon’s customer-facing apps, the companies said.
The commitment also goes beyond existing Trainium chips and includes the upcoming Trainium4, expected to be delivered next year.
“OpenAI and Amazon share a belief that AI should show up in ways that are practical and genuinely useful for people,” OpenAI CEO Sam Altman said in a statement. “Combining OpenAI’s intelligence with Amazon’s infrastructure and global reach helps us put powerful AI into the hands of businesses and users at real scale.”
Amazon’s $50B will come in two tranches: $15B initially and then $35B in the coming months when certain conditions are met. The companies did not specify what those conditions were, but previous reports indicated the additional money could be tied to an OpenAI IPO or its achievement of artificial general intelligence.
Nvidia
OpenAI also said that it was expanding its long-standing deal with Nvidia. It will use 3 gigawatts of dedicated inference capacity and 2 gigawatts of training on Nvidia’s upcoming Vera Rubin systems.
“We’re pushing the frontier across infrastructure, research, and products to make AI more capable, reliable, and broadly useful,” Altman added. “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.”
SoftBank
Upon completion of the funding round, SoftBank now owns approximately $64.6B worth of OpenAI, or roughly 13% of the company.
Microsoft
Given the more in-depth relationship between Amazon and OpenAI, OpenAI also provided an update on its relationship with Microsoft (MSFT).
“As conversations around AI investments and partnerships grow and as OpenAI announces new funding and new partners as they did today, we want to ensure these announcements are understood within the existing construct of our partnership,” OpenAI and Microsoft said in a joint statement. “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.”
Core tenets of the relationship include that the two companies will continue to “work closely” across research, engineering, and product development; Microsoft still has its exclusive licenses and access to intellectual property across OpenAI models and products; the commercial and revenue share relationships are unchanged; and Azure is still the exclusive cloud provider of stateless OpenAI APIs.
OpenAI added that its first-party products, including Frontier, will still be hosted on Azure, and the definition of artificial general intelligence and processes remains unchanged.
“The partnership was designed to give Microsoft and OpenAI room to pursue new opportunities independently, while continuing to collaborate, which each company is doing, together and independently,” the two companies added. “We remain committed to our partnership and to the shared mission that brought us together. We continue to work side‑by‑side to deliver powerful AI tools, advance responsible development, and ensure that AI benefits people and organizations everywhere.”
