Who owns 90% of the stock market?

Who Really Owns the Stock Market?

When we hear that stock market participation is at an all-time high, it’s easy to imagine a financial landscape where wealth is widely shared. After all, with apps making investing simpler than ever and retirement accounts like 401(k)s more common, doesn’t that mean more Americans are getting in on the action? Not quite.

Despite record numbers of people dabbling in the market, ownership remains heavily concentrated. According to Federal Reserve data, the wealthiest 0% of Americans—those with the highest net worth—own a staggering 93% of all stocks. That means nearly all the value in the stock market is held by a small fraction of the population.

This imbalance isn’t new, but it’s more pronounced than ever. While millions may own a few shares or contribute to retirement funds, the bulk of equity wealth sits in the hands of the richest households. For many in the bottom 90%, stock market holdings are often limited to retirement accounts, which tend to be modest compared to the vast portfolios of the top 10%.

Meanwhile, the ultra-wealthy benefit not just from greater access to investment opportunities, but also from compounding returns, tax advantages, and early entry into high-growth assets like private equities and tech IPOs—avenues typically out of reach for average investors.

So while financial democratization sounds promising in theory, the reality is that ownership of the market still mirrors broader patterns of wealth inequality. The stock market may be more accessible than ever, but ownership remains far from equal. As of January 2024, the concentration of stock wealth continues to reflect a system where the richest few hold most of the cards—and the market itself.
