Pershing Square Fund, led by Bill Ackman, announced on Tuesday that its newly established closed-end fund has raised $5 billion as part of its initial public offering (IPO) in the United States. According to Jin10, this IPO marks the realization of Ackman's long-held ambition to list a flagship fund in New York. The new fund is Pershing Square's first offering to U.S. institutional and retail investors without charging performance fees. Ackman previously attempted to bring the new fund, Pershing Square America (PSUS), to the public market in 2024, but withdrew the IPO application days before listing in New York due to lower-than-expected demand. Pershing Square America and Pershing Square will begin trading on the New York Stock Exchange on Wednesday under the ticker symbols "PSUS" and "PS."
