New York, Wednesday, 11 March 2026.
Bill Ackman seeks up to $10 billion in a unique stock market debut, where fund investors automatically receive shares in his management company at no additional cost.

A Unique Dual-Listing Strategy

On March 9, 2026, Pershing Square filed registration statements with the US Securities and Exchange Commission for a highly anticipated dual initial public offering [2][4]. The proposed transaction involves two distinct entities: Pershing Square USA, Ltd. (PSUS), a new closed-end investment company, and Pershing Square Inc. (PSI), the parent company of the investment advisor, Pershing Square Capital Management [2][4]. If approved, both entities will list on the New York Stock Exchange under the ticker symbols “PSUS” and “PS,” respectively [2].

Capitalizing on Momentum and Commitments

Bill Ackman’s firm is targeting an aggregate offering size between $5 billion and $10 billion [1][4]. Out of the $5 billion minimum target, Pershing Square has already secured $2.8 billion—accounting for 56% of the baseline goal—through a private placement [2][6]. These initial commitments, translating to 55.6 million PSUS shares, have been sourced from a robust network of institutional investors, family offices, pension funds, and ultra-high-net-worth individuals [1][4]. The remaining funds, estimated to be between $2.2 billion and $7.2 billion, will be raised directly through the public IPO [6].

The Berkshire Hathaway Blueprint

Ackman’s strategic pivot to the public markets reflects his long-standing admiration for Warren Buffett. Ackman has openly described himself as a “Buffett devotee” and considers the 95-year-old legendary investor an “unofficial mentor” [1]. By converting Pershing Square Holdco, L.P. from a Delaware limited partnership into a Nevada corporation to form PSI, Ackman is laying the groundwork for a permanent-capital investment platform modeled directly after Berkshire Hathaway’s long-term compounding approach [1][2][7]. His ultimate vision is to utilize Pershing Square as a vehicle for acquiring majority stakes in other companies [1].

Market Reception and Regulatory Hurdles

The financial community is already showing strong interest in the dual offering. Adam Patti, CEO of VistaShares, noted that Ackman is a “legendary investor,” adding that his firm looks forward to participating in the IPO and potentially adding it to their ACKY ETF portfolio, which mirrors Pershing Square’s top publicly disclosed holdings [4]. To manage the monumental listing, Pershing Square has enlisted heavyweights Citigroup Global Markets, UBS Investment Bank, BofA Securities, Jefferies, and Wells Fargo Securities as global coordinators and bookrunners [2][5].
