Who owns 88% of the stock market in the USA?

Who Really Owns the U.S. Stock Market?

It’s a staggering figure: the top 10% of Americans now own 88% of all U.S. stocks. That means nearly nine out of every ten shares traded on Wall Street are held by a small fraction of the population. This concentration didn’t happen overnight. It’s the result of decades of compounding wealth, tax-smart investment strategies, and a growing divide between those who save and invest—and those who can’t.

While the stock market has historically returned 8–10% annually over the long term, wages for most households have climbed at a much slower pace. This imbalance has allowed those with early access to capital—often through inheritance, higher incomes, or employer-sponsored retirement plans—to build generational wealth, while others struggle just to get ahead.

One reason for this trend is the power of compounding. When investments grow year after year, and those gains are reinvested, the effect snowballs—especially when tax-advantaged accounts like 401(k)s and IRAs are involved. Over time, those who started early and stayed invested pulled far ahead.

Scott Bessent, a seasoned investor and former chief economist, points out that this isn’t just about income—it’s about behavior. The gap isn’t just between rich and poor, but between savers and spenders. Those who consistently invest, even in modest amounts, benefit from market growth. But for millions of Americans living paycheck to paycheck, putting money into the market is often an impossible choice.

This concentration of ownership raises important questions about economic fairness and access to opportunity. As the market continues to climb, the benefits are increasingly funneled to a smaller segment of society. Without broader access to investing tools and financial education, that imbalance could deepen in the years ahead.
