A $5B permanent-capital “Ackman vehicle” offering concentrated activist compounding—if it can deploy well and close the NAV discount.
Overview
Pershing Square USA, Ltd. (PSUS) is a newly launched, non-diversified, closed-end management investment company managed by Pershing Square Capital Management (PSCM) and designed to bring Bill Ackman’s historically high-conviction, activist-style public equity strategy to U.S. listed investors. The fund began operations after a combined IPO/private placement that closed April 30, 2026, raising $5B gross proceeds. PSUS aims for capital appreciation (not income) through NAV compounding in a concentrated 12–15 stock portfolio, primarily U.S.-based large-cap growth businesses. The economic model is a flat 2% management fee on NAV with no incentive fee—positioned as more investor-efficient in strong years and more stable for the manager. Institutional demand dominated the raise (~85%), while retail participation (~15%) was weaker and contributed to a poor trading debut. The closed-end “permanent capital” structure is central: it prevents redemptions, supports long holding periods, and allows opportunistic buying in downturns.
