Despite stock markets reaching all-time highs, billionaire investor Bill Ackman is placing a massive $5 billion wager on the artificial intelligence revolution. Through the successful dual IPO of Pershing Square USA (PSUS) and Pershing Square Inc. (PS) on April 29, 2026, Ackman is signaling strong confidence in the "American Experiment" and the transformative power of AI.
While many retail investors remain paralyzed by fears of a market peak, Ackman is doubling down. He dismisses recession worries and argues that the current AI surge is not a bubble but the beginning of an industrial-scale productivity boom. His conviction is bolstered by stellar earnings from Big Tech, which reported double-digit revenue growth—Amazon, for example, posted a 17% net sales increase to $181.5 billion. Capital expenditure guidance from these giants suggests the AI revolution is still in its early innings.
Ackman's strategy relies on concentrated bets in select high-quality S&P 500 companies rather than broad index investing. As the Nasdaq continues its climb, his approach highlights a growing divide between institutional investors betting on AI-driven growth and cautious sideliners waiting for a correction.
