Billionaire investor Bill Ackman is once again turning to public markets to expand his investment platform, unveiling plans for a combined offering that could raise as much as $10 billion. The deal would bring a new closed-end fund, Pershing Square USA Ltd., to the New York Stock Exchange while also giving investors equity exposure to Pershing Square Inc., the hedge fund management firm behind the strategy.
The structure of the proposed IPO is designed to give investors exposure to both the investment vehicle and the management company. Under the filing with the U.S. Securities and Exchange Commission, investors who purchase shares in the Pershing Square USA closed-end fund will also receive shares in Pershing Square Inc. For every 100 shares purchased in the fund at $50 per share, investors will receive 20 shares in the management company at no additional cost.
The combined offering aims to raise between $5 billion and $10 billion, positioning it as one of the more notable capital markets transactions of the year. If successful, the deal would further expand Pershing Square’s access to permanent capital and broaden its base of public-market investors.
Pershing Square has built its reputation around concentrated investments in a limited number of companies, often paired with activist engagement. The firm currently manages approximately $30.7 billion in assets, with about $20.7 billion representing fee-paying capital as of the end of 2025.
The IPO also reflects Ackman’s longer-term vision of creating a publicly traded investment platform similar in structure to Berkshire Hathaway, allowing investors to participate in the firm’s long-term investment strategy through publicly listed securities.
The strategy arrives at a time of heightened market volatility driven by geopolitical tensions, inflation concerns, and shifting global economic conditions. For investment firms that rely on long-term value-oriented strategies, volatile markets can create opportunities to acquire companies at lower valuations.
Pershing Square USA is expected to focus on acquiring significant stakes in a relatively small group of businesses, continuing the firm’s long-standing investment philosophy of concentrated positions. The firm’s core funds have historically held large stakes in companies such as Alphabet, Chipotle Mexican Grill, and Brookfield.
Part of the capital being raised in the offering will come from a previously secured private placement totaling roughly $2.8 billion. Those funds were committed by institutional investors including family offices, pension funds, and insurance companies. Participants in the private placement are expected to receive additional shares in the management company compared to public investors.
Once the transaction is completed, Pershing Square Inc. and Pershing Square USA are expected to trade as separate publicly listed entities. The closed-end fund will list on the New York Stock Exchange under the ticker symbol PSUS, while the asset management company is expected to trade under the ticker PS.
Unlike traditional mutual funds, closed-end funds issue a fixed number of shares that trade on an exchange. Because of this structure, the market price of the shares can trade at a premium or discount to the value of the underlying portfolio holdings.
Pershing Square already operates a similar structure through Pershing Square Holdings Ltd., its London-listed closed-end fund, which manages more than $17 billion in assets but currently trades at a discount to its net asset value.
Major investment banks including Citigroup, UBS, Bank of America, Jefferies, and Wells Fargo are leading the underwriting for the IPO.
The offering represents Ackman’s latest effort to expand Pershing Square’s reach in public markets while building a larger permanent capital base to support its long-term investment strategy.
