OpenAI announced on Friday morning that it has raised $110 billion in private funding, marking one of the largest private funding rounds in history. The round includes a $50 billion investment from Amazon and $30 billion each from NVIDIA and SoftBank, based on a $730 billion pre-money valuation. The round remains open, with OpenAI expecting more investors to join in the coming months.
“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.”
As part of this investment, OpenAI is launching major infrastructure partnerships with both Amazon and Nvidia. While some of the funding is expected to come in the form of services rather than cash, details of the exact split were not disclosed.
OpenAI’s previous funding round, closed in March 2025, raised $40 billion at a $300 billion valuation, which was then the largest private funding round on record.
Amazon Partnership
OpenAI and Amazon plan to develop a “stateful runtime environment” where OpenAI models will run on Amazon’s Bedrock platform. Additionally, the partnership will expand OpenAI’s existing AWS collaboration, which had already committed $38 billion in compute services, by another $100 billion. OpenAI has pledged to use at least 2GW of AWS Trainium compute and will develop custom models to support Amazon consumer products.
Amazon CEO Andy Jassy said, “We have lots of developers and companies eager to run services powered by OpenAI models on AWS, and our unique collaboration to provide stateful runtime environments will change what’s possible for customers building AI apps and agents.”
Reports indicate that $35 billion of Amazon’s investment is contingent on OpenAI either achieving AGI or completing an IPO by the end of the year. OpenAI confirmed that this portion of funding will arrive “in the coming months when certain conditions are met.”
Nvidia Partnership
OpenAI also confirmed its partnership with Nvidia, committing to 3GW of dedicated inference capacity and 2GW of training on Vera Rubin systems. Nvidia’s role in the round has been closely watched, with earlier speculation of a $100 billion investment later clarified as a smaller contribution. Nvidia CEO Jensen Huang stated in January, “We will invest a great deal of money. I believe in OpenAI. The work that they do is incredible.”
This historic funding positions OpenAI to scale its AI infrastructure globally and continue integrating advanced AI into everyday applications, further solidifying its leadership in the AI revolution.
