Robinhood Ventures Fund I announced Wednesday that it has completed an investment in OpenAI, acquiring roughly $75 million of the company’s common stock on April 17. The fund said the purchase represents one of its largest commitments to date.
Sarah Pinto, President of Robinhood Ventures Fund I, described OpenAI as a leading company at the frontier of artificial intelligence. Pinto framed the stake as consistent with the fund’s mission to give everyday investors exposure to what RVI views as transformative businesses shaping the future.
RVI emphasized that the investment is part of a broader effort to expand retail access to private markets. Historically, private market opportunities have been largely inaccessible to most individual investors; RVI positions this OpenAI purchase as a step toward advancing Robinhood’s stated goal of democratizing finance.
The announcement was released against a backdrop of long-term structural changes in the U.S. corporate landscape. The number of publicly traded companies in the United States has declined from about 7,000 around the year 2000 to roughly 4,000 in 2025, according to figures cited by the fund. At the same time, private firms have grown both in number and in aggregate value.
As of April 2024, there were reported to be more than 6.5 times as many private companies as public ones in the U.S. The estimated combined value of these private firms exceeded $10 trillion in the first quarter of 2025, a scale the fund cited in explaining the rationale for increasing retail access to private-market investments.
Summary of the transaction:
- Buyer: Robinhood Ventures Fund I (listed as NYSE:RVI)
- Asset purchased: Common stock of OpenAI
- Purchase date: April 17
- Approximate size: $75 million
The fund’s statement links the investment to its mission-driven strategy of broadening participation in private markets, while noting the shifting balance between public and private companies in the U.S. economy.
