- Pershing Square successfully completed a $5 billion capital raise combining an IPO with strategic share placement
- PSUS and PS ticker symbols commence NYSE trading this Wednesday

- The offering represents the largest closed-end fund IPO in United States history
- IPO participants gained one complimentary management company share for each five PSUS shares purchased
Bill Ackman’s investment firm Pershing Square has successfully closed a $5 billion capital raise through a dual-structure offering combining an initial public offering with a direct share placement. The company made the announcement Tuesday night.
Trading begins Wednesday on the New York Stock Exchange for two separate entities. Pershing Square USA represents the newly formed closed-end fund, while Pershing Square Inc serves as the management entity controlling Ackman’s entire fund portfolio.
This offering marks a milestone as the largest closed-end fund IPO ever recorded in United States markets. The deal also ranks among the most significant US capital raises seen in recent market history.
Demand significantly outpaced available shares in the offering. Institutional participants accounted for over 85% of total orders, with major allocations going to family offices, pension systems, and insurance providers.
Ackman initially attempted to bring Pershing Square USA public in 2024. That earlier effort was withdrawn just days before its scheduled launch due to insufficient investor interest.
For this second attempt, Ackman introduced a sweetener to boost participation. Each investor who purchased IPO shares received bonus equity in Pershing Square’s management company at a ratio of one share for every five PSUS shares acquired.
Investment Strategy and Structure
The newly launched fund plans to concentrate investments across 12 to 15 large-capitalization companies listed on North American exchanges. The investment approach closely replicates Ackman’s proven hedge fund methodology.
Notably, this marks the first Pershing Square investment vehicle structured without performance-based management fees. The fund targets both institutional players and individual retail investors throughout the United States.
Ackman established Pershing Square Capital Management in New York during the early 2000s. His prominence grew through high-profile activist investing campaigns at major corporations like Chipotle Mexican Grill and Canadian Pacific Railway.
He gained widespread recognition for his prescient wager against residential real estate markets leading into the 2008 financial meltdown. That controversial position generated returns estimated between $1.4 billion and $2.6 billion for Pershing Square.
Performance History of Pershing Square Holdings
Pershing Square Holdings, the firm’s London-traded closed-end fund, has delivered approximately 53% appreciation over the trailing five-year period.
The broader closed-end fund sector has experienced limited activity in recent years. These investment structures have frequently traded below their net asset values, diminishing their attractiveness to potential investors.
Citigroup, UBS Investment Bank, BofA Securities, Jefferies, and Wells Fargo Securities acted as global coordinators and lead bookrunners for the combined capital raise.
Ackman has indicated that a successful market debut could pave the way for additional closed-end fund launches from Pershing Square down the road.
The public offering comes as Elon Musk’s SpaceX gears up for what may become history’s largest private share sale, with investor presentations expected to kick off in early June.
