Cathie Wood's favorite stock surges on OpenAI deal

Robinhood Ventures Fund I (RVI) disclosed a $75 million purchase of OpenAI common stock (executed April 17), a large, concentrated bet that lifted sentiment around Robinhood Markets. The OpenAI stake pushed parent HOOD shares about 4% higher in premarket trade (from a prior close of $86.43 to roughly $89.97) and RVI rose ~11.7% to $26.95 after the bell. Cathie Wood’s ARK Invest is a prominent HOOD holder (recently buying 60,266 shares on April 16), and HOOD ranks as a top weight in ARKK, ARKW and ARKF — amplifying the stock’s market impact among ETF-driven flows and AI/fintech narratives.
