OpenAI is raising an additional $11 billion that would value the artificial intelligence company at $1.25 trillion, according to a report published this week. The funding round has not closed and is expected to be completed in the coming weeks.

OpenAI has not issued a public confirmation of the size or the price. The report did not name the investors taking part in this increment of the raise. Terms can still change before any close is announced.

Private capital has poured into a small set of companies that train large language models, even as public investors have questioned spending, regulation, and the path to profit. AI shares recently climbed after a steep drop that erased trillions of dollars in market value. That rebound has not removed doubts about how fast demand will cover the cost of chips and data centers.

Until the round closes, the $11 billion figure and the $1.25 trillion valuation remain unconfirmed.

A private price of $1.25 trillion would put OpenAI in a narrow group of closely held firms with valuations once reserved for the largest public companies. Such figures rest on expectations of rapid growth in products used by consumers and businesses. They also rest on the ability to keep raising money to pay for computing at a vast scale.

The company sells consumer subscriptions and access to its models for software developers. Any final announcement will be watched for signs of how private markets now value leading AI labs after a volatile stretch. Until the round closes, the $11 billion figure and the $1.25 trillion valuation remain unconfirmed.
