Billionaires Bill Ackman, Jeremy Grantham, and Cliff Asness Are Piling Into This AI Stock the Market Is Severely Undervaluing

Three prominent billionaire investors—Bill Ackman, Jeremy Grantham, and Cliff Asness—have made substantial investments in Microsoft, with Ackman's Pershing Square buying approximately $2 billion worth of the stock. Despite strong fundamentals including 40% Azure revenue growth and a $627 billion contracted revenue backlog, Microsoft trades at its lowest price since early 2024 at a 21x earnings multiple, presenting what these investors view as a significant buying opportunity.
