Billionaire investor Bill Ackman has officially set the wheels in motion to transform his hedge fund empire into a permanent capital powerhouse, filing for a dual initial public offering (IPO) on 10 March 2026.
The ambitious move seeks to raise up to $10 billion (£7.8bn) through the simultaneous listing of two entities: his management firm, Pershing Square Inc., and a new US-listed closed-end fund, Pershing Square USA.
