The numbers come first. Gen Z and Millennial investors now hold a combined $3.09 trillion in stocks and mutual funds, a record high and a 4.5-times increase since the pandemic alone, according to Federal Reserve data tracked since 1989. Equities have risen from just 9% of under-40 households' net worth in 1989 to 27% today — the highest share on record.
The catalyst is a housing market that has effectively closed its door on younger buyers. Home prices have surged 235% since January 2000, and costs have jumped roughly 50% in recent years alone. The average age of a first-time homebuyer has climbed from 28 in 1992 to 40 in 2025, and the median homeowner age hit 59 in 2025, up from 39 in 2005. Less than half of Gen Z and Millennials can currently afford to purchase a home, per Fortune's reporting.
'For younger adults who despair about ever being able to buy a home, investing in financial markets can be a great way to save until they can afford one,' Chen Zhao, head of economics research at Redfin, told Fortune.
The behavioral shift is measurable. 37% of 25-year-olds held a retail investment account in 2024, sixfold more than in 2015, according to a JPMorganChase Institute report. Retail investing flows rose roughly 50% from 2023 to early 2025. Gen Z is opening brokerage accounts at an average age of 19; Millennials at 25. Gen Z now makes up a third of new Charles Schwab clients, a company spokesperson told Fortune.
Younger investors are also treating equities as a liquid bridge to eventual homeownership. Among Gen Z and Millennials who recently purchased a home, one in five sold stocks to fund the down payment — twice the rate of Baby Boomers — according to a 2025 Redfin survey. More than half of Millennials say they are forced to choose between retirement investing and homeownership.
The anxiety is real. 31% of Gen Z adults say they have postponed buying a home due to financial pressure, and 34% worry they may never afford one, according to Northwestern Mutual's 2026 Planning & Progress Study. Yet 90% of Gen Z surveyed in a recent report said they still want to own a home one day, even as 79% say they are being priced out.
George Eckerd, research director for wealth and markets at the JPMorganChase Institute, told Fortune the rates of stock ownership among young Americans have 'gone up so much' that, paired with flat or softening homeownership, 'that is a significant change in the way young Americans are building wealth.' He cautioned, however, that stocks and homes remain fundamentally different tools: stocks are liquid and diversifiable, while a house is typically leveraged and concentrated in a single asset.
The market has already voted. What looks like a crisis of affordability is also, quietly, a story of American adaptability. When one asset class prices out a generation, capital finds another door. The real question is whether Washington's regulatory and zoning apparatus — the same bureaucratic machinery that helped engineer the housing shortage in the first place — will get out of the way fast enough to let younger Americans build wealth through both channels. Free enterprise does not wait for permission; it routes around the obstacle. A generation of 19-year-old equity investors is proof of that. The policy lesson is simpler than any planner will admit: remove the barriers to housing supply, and young Americans will not have to choose.
