Prediction: 2 AI Stocks Will Be Worth More Than Apple Stock Before the End of 2026
The Motley Fool· 2025-05-28 08:04
Here's what investors should know about Amazon and Alphabet. Apple is currently the third-most valuable company in the world with a market capitalization of $2.9 trillion. I think Amazon (AMZN 2.38%) and Alphabet (GOOGL 2.59%) (GOOG 2.54%) can top that figure before the end of 2026. Here's what that would mean for shareholders: Amazon's earnings growth slows to 26% annually in the next six quarters, its market value can reach $3 trillion with no change in the P/E ratio. I think that is plausible, so long as ...
