Young, Renting, and Gambling Away Finance: The Sports Betting Surge and Its Impact
Data from 2025 and 2026 show that the rise of legal sports betting, especially online, is taking a toll on the finances of young renters. Since the 2018 U.S. Supreme Court decision that opened the way for state-authorized sports betting, the industry has surged. According to one article, sports betting is legal in 38 states and Washington, D.C., with at least 27 of those states allowing online wagers.
The impact can be felt in the financials. On one hand, the housing market. Earlier this year, Gen Z accounted for nearly 50% of online betting activity in July during the 2026 FIFA World Cup, according to data from Bank of America. That's a sign that young renters are also more likely to engage with sports betting, which could affect their ability to save for a down payment on a first home.
On the other hand, research shows sports betting is tied to rising debt, credit card overdrafts and bankruptcy, according to studies from the National Bureau of Economic Research, Springer, and UCLA, calling on regulators to provide more resources to online gamblers.
Credit-card, savings strains in public-spirited money
The 2025 NBER study, which cited a "staggered difference-in-differences design" from 2022, found that households already dealing with tightening margins suffered a host of financial strains. Their credit-card balances rose by $368, while missed payments climbed 11.9%.
Further, households headed by a Black respondent saw credit-card debt surge 29.7% in dollar terms. Moreover, when the sports gambler's head of household was a man 45 or younger, credit-card debt jumped 13.4%.
A separate 2026 study by Springer reached similar conclusions, and noted that there were even greater strains for men aged 25–45 whose household had Black or Latinx heads of household, a group perhaps hit by a triple whammy of income, job-access, and lifestyle effects.
Loan delinquencies, bankruptcy filing rates rise
The UCLA Anderson School of Management also cited a "Modestly" harmful financial impact on consumers due to recent legalization, primarily among young adults and households on tighter budgets, with average credit scores sliding 0.800 points in states where sports gambling was flagged as legal. But access to online gambling could significantly worsen the effects, the study found — credit scores dropped 2.750 points for region-wide online/mobile permitting, debt-payment methods also moved in the wrong direction, along with percentiles, bankruptcy, debt-stacked, delinquent auto-credit and more going skywards.
The study mentioned a key informal factor, often called bank-card churn, of frequent bank-card account opening and switching, to either add more credit card credit available or to hide or evade reporting of new debt. But it didn't put down any estimates in the text.
Regulators have not specified any general-case limits to the credit-card opening and switching that analysts assigned tentatively to the rise of young sports gamblers.
Few realizing they 'lost big time' with card churn. So just how many young sports gamblers over-interpreted the fuzzy borders of fairness in card churn? According to CNBC, only 3% of survey takers thought that their finances worsened, and many understated it, saying the sports gambling was innocent "entertainment", or left it unmentioned. Bloomberg reports that the 2026 FIFA World Cup drove shifts in overt demographic indices — an over-50 age group drove a 180% rise in sports gamblers from January, rising "rate of first-time online sports wagers in June and July", to 40% higher for the year.
But few openly stretched the winnings to include legal contests — and economists worry about future economic and emotional explosion of hidden debts that may be due to the card-churning.
The NBER, Harvard, and UCLA's warning on youth relationships may require harder and broader support from regulators before deepening contemporary Generation-Z lifestyle complexity takes hold and creates a worldwide reversion to earlier ages of excess.
