Ackman Says AI Threats Are Leaving Durable Incumbents Mispriced

Bill Ackman told the All-In hosts that Pershing Square’s investment filter has shifted toward durable business quality while remaining activist where influence can extend a company’s time horizon. He argued that AI has made disruption risk the first question for long-term investors, even as markets may be overlooking incumbents such as Microsoft, Meta and Amazon. Ackman also cast founder control, valuation discipline and permanent capital — including his Howard Hughes project — as ways to underwrite businesses through a period when public markets and CEOs are still working out AI’s practical effects.
