Billionaire Bill Ackman Has Been All-In on Uber. Is Now the Time to Buy the Stock?

Billionaire investor Bill Ackman has made Uber his largest position, betting on the company's strong operating leverage and resilience against autonomous vehicle disruption. Uber's Q3 2026 results showed robust growth with gross bookings up 20% and adjusted EBITDA jumping 31%, while the stock trades at an attractive forward P/E of 16. Despite strong fundamentals, the stock is down 25% over the past year, presenting a potential buying opportunity for long-term investors.
