Goldman Sachs Puts AI Mania at 86th Percentile, Below 2021 and 2000 Peaks

Summary
Goldman Sachs said today’s AI-driven market exuberance ranks at the 86th percentile across nine bubble metrics, below the 95th percentile in 2021 and 100th percentile in 2000.
A 27% three-month momentum surge looks elevated, but Goldman said this rally is being supported by fundamentals: forward S&P 500 earnings estimates have risen 16% year to date versus an 8% index gain.
Market breadth is the weakest since 2000, showing the rally remains narrow, though still not as extreme as at the dot-com peak.
Speculative trading in penny and unprofitable stocks remains well below 2021 and 2000 highs, while the AAII survey shows retail investors are still net bearish over the next six months.
Yale’s confidence index is the main red flag: investors are as eager to buy dips as in past bubble eras even as AI bubble fears grow and major IPOs from SpaceX, Anthropic and OpenAI loom.

Overview
As of June 2026, the U.S. stock market is rallying rapidly, driven by advancements in artificial intelligence. This surge has pushed the S&P 500 to repeated record highs and sparked growing concerns among investors about unsustainable enthusiasm. While Goldman Sachs acknowledges that signs of market exuberance are rising and risks for investors are increasing, their analysis shows that current market indicators have not yet reached the extreme levels seen in past bubbles. Investor sentiment remains highly confident, reflecting a willingness to buy despite high valuations, but experts warn that the market is moving closer to a critical juncture.
