Dot-Com vs. AI Stock Cycles: “The Optimist” Stock Talk Update September 11, 2026
The AI boom keeps getting compared to the dot-com bubble. But what if the comparison is right—and the timing is wrong? A Bespoke Investment Group chart compares the Nasdaq after the launch of Netscape in 1994 with the Nasdaq after the launch of ChatGPT in 2022. At a comparable point in the two cycles, today lines up closer to September 1998 than the March 2000 dot-com peak. That doesn’t mean history will repeat. Historical comparisons aren’t forecasts. But it raises an important question: What evidence would tell us this AI cycle is nearing the end—and what evidence would suggest it may still be developing? In this episode of Stock Talk, we examine four major pieces of the argument: The historical Netscape-versus-ChatGPT market comparison, the spread of AI adoption and productivity, corporate earnings momentum, and today’s valuation and interest-rate risks. We also look at the massive increase in data-center construction, the difference between FOMO and what Ed Yardeni calls “Fabulous Earnings Momentum,” and evidence that market leadership has broadened beyond the Magnificent Seven. The goal isn’t to predict where stocks go next. It’s to ask a better question about where we may be in this technology and market cycle—and what evidence investors should watch from here.
