OpenAI has secured about $8.3 billion in fresh financing at a valuation of roughly $300 billion, the New York Times reported, citing people familiar with the matter. The oversubscribed round closed months earlier than planned and forms part of the artificial-intelligence pioneer’s broader effort to raise as much as $40 billion this year. The latest investment deepens backing from existing supporters, including Microsoft, and drew interest from institutional investors such as SoftBank, according to earlier reporting by The Information. Demand for the round was about five times the amount sought, underscoring investor appetite for generative-AI businesses. Financial momentum at OpenAI continues to accelerate. Annual recurring revenue has climbed to roughly $13 billion, up from $10 billion in June, the Times said, while The Information previously estimated that overall revenue has doubled to about $12 billion. The fresh capital and rapid sales growth position the company to expand its computing infrastructure and product lineup amid intensifying competition from rivals powered by Nvidia and AMD chips.
