Bearish for the S&P 500
AI Bubble Overvaluation Risk
Stable
Steady attention in S&P 500 coverage, without a clear trend.
Updated 14 October 2026
The bearish argument: Michael Burry and other market observers have warned that the current AI investment cycle exhibits bubble characteristics potentially exceeding the 1990s tech bubble, with valuations disconnected from fundamental earnings power. The scale of optimism and capital deployment into AI infrastructure raises questions about whether returns will justify the massive buildout.

“Ray Dalio was less sanguine, saying AI was in a "classic bubble" and there was a difference between "how terrific a technology is and how terrific an investment is." He told the Forbes event that rising rates and changing circumstances had not "yet had a negative effect on other things," but that there was pressure for interest rates to rise further.
