Americans and the Stock Market
Currently, Americans are more engaged with the stock market than ever before.
Data indicates that by the end of 2025, around a third of U.S. household wealth was invested in stocks. According to the Federal Reserve System, this trend highlights how the ongoing AI-driven bull market is rewarding investors while also making them susceptible to possible downturns.
At the close of the year, households and nonprofit organizations held approximately $67.77 trillion in stocks, which accounted for nearly 33% of total assets. Axios noted that this is a significant increase compared to the 30% peak during the meme stock and SPAC frenzy of 2021, and even greater than the 27% seen at the height of the dot-com boom in early 2000.
This notable rise stemmed from a stock market rally that added $10.31 trillion to household portfolios in just 2025, marking an 18% increase in stock holdings within a year.
JPMorgan analysts pointed out that individual investors have played a crucial role in driving this stock bull market, stating, “Households are increasingly willing to hold stocks among their total financial assets.”
However, the benefits of this market growth are skewed towards the wealthiest Americans.
The top 10% of households own about 87% of total stock market assets, suggesting that the booming market mostly advantages wealthy investors, while many others struggle with rising living costs and inflationary pressures.
Consequently, affluent households, buoyed by increasing portfolio values, are spending freely, while low- and middle-income families are feeling the financial squeeze.
Such wealth concentration in stocks adds a layer of risk for investors. A sudden market downturn could erase trillions in paper wealth, which would impact consumer spending, retirement accounts, and the economy overall.
Scott Martin from Kingsview Wealth Management commented, “Wall Street and Main Street are telling two different stories right now.” He illustrated the situation: property values are soaring on Wall Street, but affordability is a real issue on Main Street.
This disconnect is baffling economists, especially as unemployment remains low, the economy is expanding, and stock prices are hovering near record highs. Martin remarked, “This disconnect helps explain why GDP is growing, unemployment is low, and markets can approach record highs even as consumer sentiment remains surprisingly weak.”
Many individuals are preoccupied with everyday expenses rather than stock market fluctuations. For instance, concerns about grocery bills or gas prices often overshadow care for what the Dow is doing.
Some market veterans see similarities to past market dynamics when specific stocks held excessive weight in investor portfolios. Derek Leisfield, co-founder and former chairman of MarketWatch, expressed concern over the concentration of stock ownership, pointing out that the “Magnificent Seven” (Apple, Microsoft, Amazon, Alphabet, Meta, Nvidia, and Tesla) now make up 34.8% of the S&P 500, up from 29.1% five years ago.
Leisfield referenced historical events, noting that intense focus on specific stocks like during the Internet boom led to unfortunate outcomes for many investors.
Still, Martin emphasized that the greater risk is not that average Americans are overexposed to stocks but rather that most are not involved at all.
“The bigger risk is that much of the country’s growth in wealth is concentrated in a small group of investors and a limited number of stocks,” he said. If the market experiences a sharp reversal, it wouldn’t just impact wealthy individuals.
Martin noted, “The direct financial impact will be concentrated on wealthy households, which hold the majority of stocks. But everyone will feel the knock-on effects of lower confidence, slower spending, and a weaker economy.”
