Gen Z's Money Knowledge Hits a Decade Low as Bets Grow

Gen Z's Money Knowledge just hit its lowest point in ten years, according to a national test of financial know-how — and the timing could hardly be worse. Young adults are placing bigger, riskier bets with their savings at exactly the moment their grasp of the basics is weakest.

The 2026 Personal Finance Index from the TIAA Institute and the Global Financial Literacy Excellence Center found that American adults answered only forty-seven percent of twenty-eight basic money questions correctly. That is the weakest result in the survey's ten-year history, and Gen Z finished at the bottom of every generation measured, getting just thirty-eight percent right. The share of adults with very low financial knowledge has grown from one in five in 2017 to one in four now, according to the institute's write-up of the findings.

The questions young adults keep getting wrong

The trouble spots read like a map of where real money gets lost. Comprehending risk was the weakest area of all, with only thirty-six percent of risk questions answered correctly. Retirement questions stumped nearly everyone: adults averaged only two correct answers on that section. Declines showed up across five of the eight areas the index tracks — consuming, borrowing, earning, insuring, and comprehending risk — which suggests the slide is broad rather than tied to one confusing topic. A gender gap persists too, with women scoring roughly six points lower than men.

None of this looks like a generation ignoring money. It looks like a generation handed the tools before the manual. Gen Z opens trading apps before budgeting apps, and the vocabulary of bank accounts and workplace retirement plans is arriving late. As Money Under 30 wrote in its coverage of the findings this month, many young adults now hold investing apps in their hands before they have built the vocabulary those accounts require.

The bets are getting bigger anyway

While scores fell, risk-taking climbed. A January 2026 study from Northwestern Mutual, surveying more than forty-three hundred adults, found that forty percent of Americans are investing in or considering high-risk assets including cryptocurrency, sports betting, and prediction markets. Among Gen Z, crypto participation reached thirty-two percent, well above the overall adult rate.

The mindset behind those bets is understandable. Eight in ten Gen Z respondents drawn to high-risk assets said they feel financially behind, and they believe one big win could help them catch up faster than steady investing. The problem is that the math rarely cooperates. A Bloomberg analysis of every Polymarket wallet active since last year found nearly twice as many accounts had lost at least a thousand dollars as had made that amount.

Why the gap matters now

Low knowledge and high risk make an expensive pair, and the consequences are not abstract. The institute found that adults who score low on the index are four times more likely to struggle making ends meet and three times more likely to be financially fragile. An early wipeout does more than cost money: it can push a new investor out of the market entirely, right when compounding would matter most.

There is a counterpoint worth sitting with. Access to investing has never been wider, and starting early still beats starting late for most people who survive their mistakes. The index itself suggests the fix is boring rather than brilliant: learn a few core terms, read one plain-language explainer a week, and build a cash cushion before taking real risk. Small, consistent learning beats any single crash course.

The classroom story adds a twist. Thirty-nine states now require high school students to take a personal finance course to graduate — four more than two years earlier — yet scores keep falling. "The level and complexity of the decisions that consumers face today is at an all-time high," said Gustavo Barboza, a professor of international business at Loyola University New Orleans, in an interview with NerdWallet about teaching money at a recent Stanford University conference. The products keep multiplying — crypto, prediction markets, AI-driven trading — while the fundamentals stay flat. That mismatch is the real story behind the decade's worst Money Knowledge reading.
