OpenAI secures $110B in one of the biggest private funding rounds ever

OpenAI said Friday morning that it has raised $110 billion in private funding, kicking off what ranks among the biggest private financing rounds ever. The new capital includes a $50 billion commitment from Amazon, plus $30 billion each from Nvidia and SoftBank, and values the company at a pre-money valuation of $730 billion.

OpenAI also noted that the round remains open and that the company expects additional investors to participate as fundraising continues.

“We are entering a new phase where frontier AI moves from research into daily use at a global scale,” OpenAI said. “Leadership will be defined by who can scale infrastructure fast enough to meet demand, and turn that capacity into products people rely on.”

Alongside the financing, OpenAI said it is forming major infrastructure partnerships with both Amazon and Nvidia, as in prior funding rounds, a meaningful share of the headline amount is likely to be provided as services rather than pure cash. However, OpenAI did not disclose the exact breakdown.

OpenAI’s prior round closed in March 2025, when it raised $40 billion at a $300 billion valuation—at the time, the largest private funding round ever recorded.

Within the Amazon partnership, OpenAI plans to build a new “stateful runtime environment” to enable OpenAI models to operate on Amazon’s Bedrock platform. The company also said it will expand its previously announced AWS partnership—originally committing $38 billion in compute services—by an additional $100 billion. As part of the arrangement, OpenAI has committed to consuming at least 2 GW of AWS Trainium compute and plans to develop custom models to support Amazon consumer products.

“We have lots of developers and companies eager to run services powered by OpenAI models on AWS,” Amazon CEO Andy Jassy said in a statement, “and our unique collaboration with OpenAI to provide stateful runtime environments will change what’s possible for customers building AI apps and agents.”

The Information had previously reported that $35 billion of Amazon’s investment might be conditional on OpenAI either reaching AGI or completing an IPO by the end of the year. OpenAI’s announcement confirms the overall split but says only that the additional $35 billion will be delivered “in the coming months when certain conditions are met.”

OpenAI shared fewer specifics about the Nvidia partnership, but said it has agreed to use “3GW of dedicated inference capacity and 2GW of training on Vera Rubin systems” under the deal.

NVIDIA’s participation has drawn significant speculation, especially after reports of a possible $100 billion investment last September, followed by reports of a smaller check in subsequent months.

In January, Nvidia CEO Jensen Huang pushed back on the idea that Nvidia was stepping away from OpenAI, saying, “We will invest a great deal of money. I believe in OpenAI. The work that they do is incredible.”
