Bill Ackman Warns Market Repeating Dot-Com Bubble, Says Amazon, Meta, Microsoft Undervalued on June 3

According to Bill Ackman on the All In podcast on June 3, the billionaire Pershing Square Capital founder warned that current market dynamics mirror the 2000 dot-com bubble era. Investors are blindly chasing the hottest sectors—chips, semiconductors, and energy—while neglecting quality assets, he said.

Ackman identified Amazon (AMZN), Meta (META), and Microsoft (MSFT) as undervalued tech giants facing similar dismissal to what Berkshire Hathaway experienced during the earlier bubble. He holds all three in his investment portfolio and emphasized that both history and market psychology show that genuine value often gets overlooked when capital concentrates on trendy themes.
