Robinhood CEO Vlad Tenev revealed that 150,000+ retail investors joined the company's venture fund (RVI), which raised $658.4M at IPO and now trades on the NYSE. The fund offers exposure to private tech companies including OpenAI ($75M investment closed April 17), Stripe, Databricks, and Oura — with no accreditation requirements, no carry fees, and daily liquidity. However, shares traded 11-16% below the $25 IPO price on debut.
