Summary
Bill Ackman's Pershing Square USA (PSUS) commenced trading on the New York Stock Exchange on April 29, 2026, marking the largest initial public offering in history for a closed-end fund. The offering raised $5 billion at an IPO price of $50 per share, representing the low end of Ackman's initial $5 billion to $10 billion target range. Simultaneously, Pershing Square Inc. (PS), Ackman's asset management firm, began trading and will serve as the investment manager for PSUS, Pershing Square Holdings (the UK-listed predecessor fund), and Howard Hughes Holdings.
The offering demonstrated substantial institutional demand, with more than 85% of orders originating from institutional investors. Cornerstone investors committed $2.8 billion of the $5 billion total raise, with their positions subject to a six-month lockup period. To incentivize participation, Ackman structured an unusual sweetener: all PSUS investors receive one free share of Pershing Square Inc. for every five PSUS shares purchased, while cornerstone investors receive 1.5 PS shares per five PSUS shares acquired. This dual-IPO structure reflects Ackman's strategy to open his hedge fund to retail investors while maintaining institutional appeal through his management company's public listing.
According to PSUS's prospectus filed with the Securities and Exchange Commission, the closed-end fund will invest in "large minority stakes in high-quality, predominantly North American-listed, large-capitalization growth companies at attractive valuations during periods in which we believe they have underperformed their potential and/or when we believe they are undervalued." This investment mandate mirrors Pershing Square Holdings' current portfolio, which includes significant positions in Alphabet (the top holding across all Pershing Square funds), Amazon, Meta Platforms, Uber Technologies, Brookfield, Fannie Mae, and Freddie Mac. The new fund provides Ackman's retail and institutional base with direct exposure to his concentrated, high-conviction investment thesis on undervalued large-cap growth equities.
This IPO follows Ackman's withdrawal of a similar offering in 2024 due to insufficient demand, indicating that market conditions and structural incentives have now aligned to support a massive closed-end fund launch. The $5 billion raise and strong institutional participation underscore renewed appetite for Ackman's investment approach among sophisticated investors, despite the offering falling short of the upper $10 billion target.
