Billionaire investor Bill Ackman plans an IPO for his Pershing Square investment firm as early as next year, potentially valuing it at $10.5bn. The IPO comes amid a booming stock market and follows a recent funding round where Ackman sold a stake in the firm, with the funds used to seed additional investment funds. The move could increase Pershing Square's visibility and provide it with more capital for future projects.
