Bill Ackman is making a second run at the public markets, filing documents for a dual initial public offering that would list both his Pershing Square fund management company and a new investment fund on the New York Stock Exchange, seeking up to $10 billion in combined proceeds.
The filing, submitted on March 10, represents a revived ambition for Ackman after earlier plans to take Pershing Square public collapsed in 2024. The hedge fund manager is now offering investors something structurally distinct from that prior attempt, pairing the management company listing with the simultaneous launch of a new fund.
According to Bloomberg and Reuters, the two offerings are being pursued in tandem, with the new fund forming a central part of the pitch to prospective investors. MarketWatch noted that Ackman is once again trying to take his fund management company public alongside the launch of a new fund, a structure that analysts described as worth close examination.
The filings released publicly have shed light on the inner workings of Pershing Square, including details of Ackman's own compensation arrangements, the Wall Street Journal reported. Such disclosures are a standard feature of the IPO registration process but are closely watched given Ackman's prominent public profile.
As part of the offering, Ackman is reported to be giving prospective investors shares in the fund management business, a feature MarketWatch described as a fund-management share giveaway designed to attract retail and institutional capital alike.
The target of up to $10 billion would represent a substantial capital raise. Forbes noted that earlier plans to list the hedge fund had fallen apart in 2024, making the renewed attempt a test of both market appetite and investor confidence in Ackman's franchise.
Pershing Square's existing closed-end fund has traded in Europe under the ticker PSHZF on the over-the-counter market in the United States, giving some institutional investors prior exposure to Ackman's listed vehicles. The new NYSE listing would give the management company and the new fund a domestic US exchange home for the first time.
Ackman has been one of the most closely followed figures in the hedge fund industry, known for concentrated long and short positions and a willingness to engage publicly with his investment theses. The IPO filings place his firm's financials and strategy under fresh regulatory and investor scrutiny ahead of any listing.
