My Prediction: American Stock Ownership Will Drop to 54% by 2030. One Sector Is Driving It.

The author predicts U.S. stock ownership will decline from 58% to 54% by 2030, primarily driven by cooling AI sector enthusiasm. New retail investors who poured $300 billion into stocks last year seeking AI gains are now facing disappointing performance from major tech stocks. Additional factors include record margin debt levels ($1.4 trillion) that could trigger margin calls, and elevated market valuations suggesting only 6-7% annualized returns over the next decade. Disillusioned investors may redirect capital to alternative investments like real estate and cryptocurrency.
