Who owns 88% of the stock market?

Who Really Owns the Stock Market?

It’s a staggering figure: the top 10% of Americans now control 88% of all U.S. stocks. Economist Scott Bessent recently highlighted this lopsided ownership as a product of long-term trends—decades of compounding returns, strategic tax-advantaged investing, and a growing divide between those who save and those who spend.

This concentration didn’t happen overnight. Over the past several decades, rising stock values have disproportionately benefited those who already had capital to invest. Meanwhile, retirement accounts like 401(k)s and IRAs—often touted as tools for broad financial inclusion—have largely favored higher earners who can afford to max them out. Lower-income households, on the other hand, frequently face barriers like inconsistent employment, lack of employer-sponsored plans, or urgent financial needs that make long-term investing a low priority.

Compounding wealth begets more wealth. When returns on investments are reinvested over time, especially in a market that has seen steady growth, the advantage accumulates rapidly for those already in the game. Add in tax policies that favor capital gains over earned income, and the gap only widens.

The result? A financial landscape where ownership of the market’s gains is highly concentrated. While the stock market is often discussed as a collective barometer of economic health, the reality is that for most Americans, its rewards remain distant and abstract.

This growing imbalance isn’t just about numbers—it’s a reflection of deeper economic divides. As more wealth concentrates at the top, the dream of widespread financial participation becomes harder to realize. Without structural shifts in access, education, and policy, that 88% may not just be a statistic, but a symbol of a system tilted in favor of the few.
