NEW YORK — Billionaire investor Bill Ackman is officially bringing his hedge fund empire to the New York Stock Exchange. In a long-awaited move that could reshape the landscape of publicly traded asset managers, Ackman’s firm, Pershing Square, filed registration statements with the SEC Tuesday for a high-stakes initial public offering.
The filing details a complex, combined transaction. The primary vehicle, Pershing Square USA, Ltd. (PSUS), a closed-end investment company, is targeting a massive capital raise of up to $10 billion. Alongside it, the management company itself—Pershing Square Inc.—will list under the ticker symbol “PS.”
A Multi-Billion Dollar Bet on Permanent Capital
The “combined IPO” structure is designed to cement Ackman’s transition from a traditional hedge fund manager to the head of a permanent capital institution, a vision he has likened to Warren Buffett’s Berkshire Hathaway.
According to the prospectus, PSUS has already secured $2.8 billion in commitments from a diverse group of institutional heavyweights, including pension funds, insurance companies, and family offices. The firm expects to raise an additional $2.2 billion to $7.2 billion through the public offering, with shares priced at $50.00.
In a move to incentivize early participation, investors in the PSUS IPO will receive shares of the management company (PS) for no additional cost. Specifically, public investors will receive 20 shares of “PS” for every 100 shares of “PSUS” they purchase.
Shifting Gears After Past Setbacks
This filing marks a aggressive comeback for Ackman, who faced a high-profile setback last year when he was forced to withdraw an earlier iteration of the PSUS IPO due to cooling investor demand. By restructuring the deal to include equity in the management company itself, Ackman is betting that the allure of recurring fee streams will attract a broader base of Wall Street capital.
As of late 2025, Pershing Square reported total assets under management (AUM) of approximately $30.7 billion, with a significant 96% of that capital classified as “permanent.” This stability allows the firm to take the concentrated, long-term activist positions for which Ackman is famous, without the risk of sudden investor redemptions.
Wall Street Watches Closely
The offering is being led by a powerhouse lineup of underwriters, including Citigroup, UBS Investment Bank, BofA Securities, Jefferies, and Wells Fargo.
While the listing will not generate direct proceeds for the firm—which is already well-capitalized—it provides a liquid currency for future acquisitions and establishes a market valuation for a brand that has become synonymous with activist investing. If successful, “PS” will join the ranks of other publicly traded alternative asset giants like Blackstone and Apollo, offering retail investors a rare seat at the table of one of the world’s most watched hedge funds.
