OpenAI announced Friday morning that it has raised $110 billion in private funding, marking one of the largest private funding rounds in history. The funding includes investments of $50 billion from Amazon and $30 billion each from Nvidia and SoftBank, with a pre-money valuation of $730 billion. The round is still open to additional investors.
“We are entering a new phase where frontier AI moves from research into daily use at global scale,” OpenAI stated. “Leadership will be defined by who can scale infrastructure fast enough to meet demand, and turn that capacity into products people rely on.”
OpenAI is forming major infrastructure partnerships with Amazon and Nvidia as part of the investment. A significant portion of the funding is expected to be in services rather than cash, though the exact breakdown wasn’t revealed.
The company’s previous round closed in March 2025, raising $40 billion at a $300 billion valuation, setting a record for private funding rounds at the time.
Through its Amazon partnership, OpenAI will develop a “stateful runtime environment” for its models on Amazon’s Bedrock platform. They will also enhance their existing AWS partnership, previously committed to $38 billion in compute services, by an additional $100 billion. OpenAI has agreed to use at least 2GW of AWS Tranium compute and plans to create custom models to support Amazon’s consumer products.
Amazon CEO Andy Jassy stated, “Our collaboration with OpenAI to provide stateful runtime environments will change what’s possible for customers building AI apps and agents.”
The Information previously reported that $35 billion of Amazon’s investment might hinge on OpenAI achieving AGI or making its IPO by the year’s end. OpenAI’s announcement confirms the funding terms but notes that the additional $35 billion will come “in the coming months when certain conditions are met.”
OpenAI provided limited details on the Nvidia partnership, disclosing a commitment to using “3GW of dedicated inference capacity and 2GW of training on Vera Rubin systems” as part of the agreement.
Speculation has surrounded Nvidia’s participation, particularly as reports of a $100 billion investment in September were followed by reports of a reduced investment. In January, Nvidia CEO Jensen Huang refuted claims of backing away, stating, “we will invest a great deal of money. I believe in OpenAI. The work that they do is incredible.”
