The "AI Big 10" now control 42% of the entire U.S. stock market.
That's the Mag 7 plus $AVGO, $AMD, and $MU. This share has more than doubled since the 2022 bear market low.
For context:
• 2000 Dot-Com peak: TMT sector hit 41%
• 1970s Nifty Fifty: peaked at 40%
• 1980s Japan bubble: topped at 44%
Only railroad stocks in the 1900s went higher at 63%.
This level of concentration is historically rare. When a handful of names carry the entire market, it's worth watching what happens when the narrative shifts or earnings disappoint.
Not saying it crashes tomorrow, but these comparisons aren't random. Market structure matters.
