OpenAI announced today that it closed a $110 billion funding round with participation from Amazon, Nvidia, and SoftBank. The ChatGPT maker also announced a new strategic partnership with Amazon to develop custom models to power Amazon’s customer-facing applications.
Amazon invested $50 billion in the round, while Nvidia and Softbank both invested $30 billion in the company. This results in a $730B pre-money valuation for OpenAI, which previously crossed a $500 billion valuation in October. “Additional financial investors are expected to join as the round progresses,” OpenAI said today.
In addition to its new partnership with Amazon, OpenAI also announced that it’s expanding its existing collaboration with Nvidia to secure next-generation inference compute. The AI startup also continues to partner with Microsoft, which still has an exclusive license and access to intellectual property across OpenAI models and products. “Our stateless API will remain exclusive to Azure, and we will build out much more capacity with them,” OpenAI CEO Sam Altman said today.
We continue to have a great relationship with Microsoft. Our stateless API will remain exclusive to Azure, and we will build out much more capacity with them.

“We are entering a new phase where frontier AI moves from research into daily use at global scale. Leadership will be defined by who can scale infrastructure fast enough to meet demand, and turn that capacity into products people rely on. This funding and these partnerships let us do both, and move faster on our mission to ensure AGI benefits all of humanity,” OpenAI said today in a press release.
As part of the new funding round announcement, OpenAI also announced that ChatGPT now has more than 900 million weekly active users, more than 50 million consumer subscribers, and more than 9 million paying business users. On the consumer side, the company said that January and February are “on track to be the largest months for new subscribers in our history.”
