OpenAI has closed a $110 billion funding round, valuing the company at $730 billion. Amazon contributed $50 billion, Nvidia $30 billion, and SoftBank $30 billion. Additional investors are expected to join. The round is the largest private financing in history, surpassing OpenAI’s own $40 billion round from the previous year.
Amazon’s $50 billion commitment begins with an initial $15 billion, with the remaining $35 billion to follow when certain conditions are met. Alongside the investment, Amazon and OpenAI announced a multi-year strategic partnership. AWS will serve as the exclusive third-party cloud provider for OpenAI Frontier, an enterprise platform that allows organizations to build and manage teams of AI agents. The two companies will also jointly develop a Stateful Runtime Environment, a next-generation system that allows AI models to retain context and work across tools and data sources. It will be available through Amazon Bedrock.
OpenAI is also expanding its collaboration with Nvidia, securing 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity on Nvidia’s Vera Rubin systems.
OpenAI stated that its existing partnership with Microsoft remains unchanged. Microsoft retains an option to participate in the current funding round, according to a source familiar with the matter.
OpenAI currently reports more than 900 million weekly active users on ChatGPT and over 9 million paying business users on its platform.
