Key Takeaways
- • Bill Ackman's Pershing Square IPO is expected to raise $5 billion, making it the largest-ever initial public offering for a closed-end fund and one of the largest IPOs in recent years.
- • The offering is substantially oversubscribed with over 85% of orders from institutional investors; $2.8 billion of the $5 billion target comes from cornerstone investors (family offices, pension funds, and insurance companies) with six-month lockup periods.
- • Pershing Square Inc will trade under ticker PS while the closed-end fund Pershing Square USA will trade under PSUS at $50 per share, with both expected to begin trading on April 30, 2026 (following April 28 pricing).
- • Investors in the new fund receive equity sweeteners: one share in Pershing Square for every five shares purchased in the fund; cornerstone investors receive 1.5 shares per five fund shares as additional compensation for their lockup commitment.
- • This IPO marks Ackman's second attempt at public markets for the strategy, following a 2024 withdrawal due to weak demand; Ackman has stated his vision of eventually establishing Pershing Square as a holding company comparable to Berkshire Hathaway.
Summary
Billionaire hedge fund manager Bill Ackman is poised to raise $5 billion through the initial public offering of Pershing Square, a combined offering of his investment management company and a new closed-end fund. The deal represents the largest IPO ever for a closed-end fund and ranks among the largest IPOs in recent years, according to Reuters reporting on April 27, 2026. The offering, which will see Pershing Square Inc trade under the ticker PS and Pershing Square USA (the closed-end fund) trade under PSUS, is scheduled to price on April 28 and begin trading on April 30.
The IPO achieved strong institutional demand, with the offering oversubscribed and more than 85% of orders coming from institutional investors. Of the $5 billion expected total, $2.8 billion is committed by cornerstone investors—including family offices, pension funds, and insurance companies—who have agreed to six-month lockups on their shares. The fund shares are being offered at $50 per share. Originally, Ackman had targeted a raise between $5 billion and $10 billion but ultimately settled on the lower end of that guidance, according to sources cited by Reuters.
To incentivize participation, Pershing Square is offering equity sweeteners to investors in the new fund. Standard investors receive one share in Pershing Square for every five shares purchased in the new fund, while cornerstone investors with lockup commitments receive enhanced terms of 1.5 shares per five fund shares purchased. These equity incentives tie investor returns to the performance of the parent company, structurally aligning interests between the new fund and the broader Pershing Square platform.
This IPO marks a significant milestone for Ackman after a previous attempt to take the strategy public was withdrawn in 2024 due to insufficient demand. The successful capital raise at scale reflects renewed investor appetite and validates Ackman's strategic vision. In public statements, Ackman has indicated his long-term objective is to establish Pershing Square as a diversified holding company modeled after Berkshire Hathaway, suggesting this IPO represents a foundational step toward that larger corporate structure.
