Bill Ackman’s Pershing Square would trade under the ticker ‘PS’|Senate Democrats|CC BY 2.0
Bill Ackman is moving closer to his goal of replicating his “unofficial mentor” Warren Buffett’s Berkshire Hathaway model. His hedge fund firm, Pershing Square Capital Management, filed to list on the NYSE on Tuesday.
Leveraging his two million followers on X, Ackman is targeting retail and institutional investors. He has often quoted Buffett as an inspiration and attends Berkshire’s annual shareholder meetings in Omaha, Nebraska.
Pershing Square would trade under the ticker “PS” and have a dual-listing structure, with both the firm’s common stock and its new closed-end fund, PSUS, trading independently.
Ackman aims to raise between $5 billion and $10 billion for PSUS by offering shares at $50 each. To attract investors, the firm plans to deliver 20 shares of Pershing Square common stock for every 100 PSUS shares purchased.
The company had withdrawn from its IPO plans in 2024. As of 2025, its portfolio includes large-cap companies such as Brookfield, Uber, and Amazon.
Ackman was also among the first Ivy League university donors to threaten to stop donations over campus protests against the Israel-Hamas war.
