Bill Ackman’s Contrarian AI Bet: Why Traditional Data Giants May Outlast the Hype
Bill Ackman's Pershing Square increased stakes in Visa, Mastercard, Netflix, S&P Global, Intercontinental Exchange, and Alcon, while reducing Amazon and exiting Alphabet. Ackman believes these companies will benefit from AI, citing their proprietary data and strong market positions. Pershing Square reported a -12.6% return in the first half of 2026, lagging the S&P 500. Intercontinental Exchange reported $2.7B in Q2 revenue and raised full-year guidance.
