OpenAI said on Wednesday that it had completed a $6.6 billion fund-raising deal that more than doubles the high-profile company’s valuation from just nine months ago.

The new fund-raising round, led by the investment firm Thrive Capital, values OpenAI at $157 billion, according to two people with knowledge of the deal. Microsoft, the chipmaker Nvidia, the tech conglomerate SoftBank, the UAE investment firm MGX and others are also putting money into OpenAI.

The company started the AI boom in 2022 with the release of its online chatbot ChatGPT, sparking a race to invest in start-ups that develop similar technology. And its latest investment round indicates that the tech industry’s excitement over artificial intelligence remains strong, despite concerns about the effectiveness and the safety of the technology.

Investments in AI start-ups cooled earlier this year as several were essentially swallowed by the tech giants Google, Microsoft and Amazon, which are building technology similar to what OpenAI has been working on. But OpenAI’s profile has given it a major head start. Its revenues are rising quickly, but it is losing billions of dollars because of the unusually high cost of building and running AI technologies like ChatGPT.

Just nine months ago, OpenAI was valued at $70 billion. The company now has about 1,700 employees, after adding more than 1,000 workers in that period.

OpenAI expects about $3.7 billion in sales this year, according to financial documents reviewed by The New York Times. But it also expects to lose roughly $5 billion after paying for costs related to running its services and other expenses, according to an analysis of the documents by a financial professional.

Thrive Capital has invested about $1.3 billion in OpenAI, with $750 million coming from its own fund and $550 million coming from other investors through an instrument called a special purpose vehicle, according to a person familiar with the deal. Thrive also has the option to invest up to $1 billion more in OpenAI at the same $157 billion valuation till 2025, the person said. Other investors do not have that option.

“Every week, over 250 million people turn to ChatGPT regardless of the scale of the challenge — whether it’s communicating with someone who speaks another language or solving the toughest research problems,” Sarah Friar, OpenAI’s chief financial officer, said in a statement.

The new funding arrives as the start-up fights through growing pains.
