Warburg Pincus: Investors See Public Markets as One Big Correlated Bet

Warburg Pincus CEO Jeffrey Perlman, whose private investment firm is behind more than 200 portfolio companies, stated that investors view public markets as a single concentrated correlated bet. According to him, this pushes capital into private assets. The thesis comes from a firm that calls the IPO market structurally broken for buyout exits and has sold most recent assets to corporate buyers.

Perlman spoke with CNBC after the opening bell ceremony at the New York Stock Exchange, marking Warburg's 60th anniversary. Investors worldwide, he said, increasingly describe public markets with one phrase: "one big unified correlated bet." The firm's clients want AI to be applied in traditional companies rather than turning into a bet on the next big language model. Warburg's largest single investment is in AI implementation.

Perlman estimated the share of the S&P 500 owned by ten companies at about half. However, JPMorgan data shows that in July 2026, the top 10 held about 38%. Meanwhile, Citi strategist Scott Chronert expects AI-supported earnings to justify Citi's target of 8,100 points for the S&P 500 by the end of the year.

Perlman noted that public companies have lost 60% over the decade. The number of public U.S. firms has nearly halved since 1996, according to the Harvard Law School Forum on Corporate Governance. Markets expect IPO discounts of 30–40%, and selling stakes then takes three to four years. Most of Warburg's sales over the past four to five years have gone to strategics, i.e., corporate buyers.

CNBC's Leslie Picker asked about the share of software in private markets. Perlman replied that software has a place in portfolios but is unlikely to be in the range of 30–40%. He described his approach as "diversification by design." According to him, rates are structurally higher but not high by historical standards, and the rising cost of debt, in his view, does not hinder buyouts.
