Bill Ackman, founder and CEO of Pershing Square Capital Management, issued a stark warning on the All-In Podcast on June 3, 2026: the current AI investment frenzy is repeating the mistakes of the 2000 dot-com bubble. He observed short-term capital flooding into semiconductor and energy sectors, creating a non-rational boom that mirrors history—markets always chase the latest shiny object, causing high-quality assets to be left behind.
Capital Chasing Hype, Quality Tech Giants Left Behind
Ackman pointed out that markets are abandoning Microsoft (MSFT), Amazon (AMZN), and Meta, labeling them as outdated despite their strong cash flows and durable moats. He compared this to 2000 when investors chased profitless internet stocks and treated Warren Buffett’s Berkshire Hathaway as a relic, pushing its valuation to historic lows. History is repeating, and Ackman built a large new position in Microsoft after its February earnings dip, convinced it is the true winner of the AI era.
AI Reshapes Moat, Software Sector Faces Brutal Divergence
Ackman stressed that firms failing to embrace AI face disruption. Microsoft, with its technology depth, massive user base, and deep Copilot integration, is the biggest beneficiary. Conversely, he warned about niche software companies relying on high subscription fees (e.g., $30,000 per year) and lacking AI transformation, specifically calling out Salesforce (CRM) for its business model and slow pivot. He predicted a brutal value divergence for the software industry.
Eyes on SpaceX and OpenAI, Warns of Diving Panic Index
Beyond public tech giants, Ackman is bullish on SpaceX for its near-monopoly in low-cost space launch and Starlink’s disruptive impact, and closely watches OpenAI, but stresses the need to clarify capital allocation and profitability. Macro-wise, he warned that the S&P 500 technology sector just recorded its strongest 10-week gain since 1990 (up 44.6%), while the VIX fear gauge fell to a year-to-date low of 13. Market hedging demand is extremely low, investor psychology has shifted from “fear of a crash” to “fear of missing out” (FOMO)—a dangerous environment that historically precedes a bubble burst.
Ackman’s warning highlights a structural issue: when everyone charges in the same direction, true opportunity may lie in the corners they abandon.
