OpenAI Raises $300M from Sequoia, A16Z, and Others at $27-29B Valuation

Updated to note that the Microsoft investment closed in January. The money from VCs reported here, part of a tender offer, is separate to that. 

 OpenAI , the startup behind the widely used conversational AI model ChatGPT, has picked up new backers, TechCrunch has learned.

 
 
 
 

 
 
 
 

 VC firms including Sequoia Capital, Andreessen Horowitz, Thrive and K2 Global picking up new shares, according to documents seen by TechCrunch. A source tells us Founders Fund is also investing. Altogether the VCs have put in just over $300 million at a valuation of $27 billion – $29 billion. This is separate to a big investment from Microsoft announced earlier this year , a person familiar with the development told TechCrunch, which closed in January. The size of Microsoft’s investment is believed to be around $10 billion, a figure we confirmed with our source.

 If all this is accurate, this is the closing of the tender offer the Wall Street Journal reported was in the works in January. We confirmed that was when discussions started, amid a viral surge of interest in OpenAI and its business.

 We have reached out to the investors named here, as well as to OpenAI, for comment and will update this story as we learn more. OpenAI declined to comment on the tender offer, which is separate to the Microsoft investment that closed in January.

From PitchBook data, it looks like Sequoia and A16Z had been earlier investors in the company.

 A number of firms, including  Sequoia , have had some knocks as a result of the financial crisis the tech sector has seen in the last year; in general, a number of VCs have massively slowed down their investing pace, sitting on so-called “dry powder” waiting for a better climate, and maybe better opportunities.

 
 
 
 

 
 
 
 

 So at a moment when investors are on the hunt for interesting AI startups to back , OpenAI is likely seen as the kind of opportunity that looks good right now.

 “They’re probably trying to use this [funding] to say hey, look, we found a golden apple,” a source said of the decision to back OpenAI here and now. “Venture is a very strange place where anything can happen. You
