Cathie Wood's Ark Venture Fund has agreed to invest at least $250 million in OpenAI's latest funding round, according to three people familiar with the round. The deal marks the fund's second investment in the ChatGPT maker.
The money brings the round, one of the largest in startup history, to $6.6 billion. Ark joins Thrive Capital, which led the round. Other rumored participants are Microsoft, Nvidia, and Altimeter.
Ark said in April it grabbed a stake in the company.
