🚨 AI is distorting the entire U.S. stock market in an unprecedented way.

A set of real data that makes market participants uneasy 👇
After removing AI stocks, the S&P 500 has gained only 16% over the past two years and is still below its February historical peak. Meanwhile, the entire index including AI has risen 42% over the same period, with 15 historical record breakouts already this year. Between AI and non-AI, it’s as if they’re two completely different market cycles.
The S&P 500 has been rising for 6 straight weeks, setting the longest winning streak since October 2024. But over this period, the S&P 500 rose 16%, while the equal-weighted S&P 500 rose only 8%. A rebound completely led by big companies.
10 top companies accounted for 69% of the S&P 500’s gains, while the remaining 490 companies together contributed only 31%. Market breadth has narrowed to almost a single line—one woven by AI giants.
Among them, GOOGL alone accounts for 15%, NVDA contributes 10%, and $AMZN accounts for 8%. The combined contribution of these three companies exceeds the total contribution of the remaining 490 companies.
The AI revolution is reshaping market structure—but is its true significance a profound industrial transformation, or an over-concentrated bubble? Perhaps only time can answer 🤔
