A University of Nebraska–Lincoln study found that legal online sports betting reduced household savings and investments rather than simply diverting discretionary entertainment spending. The effects were greatest for people with limited savings and households under financial strain, raising concerns about long-term financial security.
The findings appeared in the Journal of Financial Economics in a paper titled “Gambling Away Stability: Sports Betting’s Impact on Vulnerable Households.” The researchers examined transactions from 183,821 U.S. households and tracked investing, spending and debt management after online wagering became legal in 26 states.
Justin Balthrop said legalization quickly increased both the number of participants and the frequency of bets. That increase did not displace other gambling or consumer spending, he said, but significantly reduced savings.
Frequent bettors reduced savings and debt payments most sharply. They also tended to have lower incomes, smaller investment balances and higher credit-card debt than infrequent bettors and non-bettors.
The study defined a budgetarily constrained household as one spending close to all of its income, including households with substantial earnings but little money left after expenses. Such households, along with those with limited savings, faced the greatest financial consequences. The research found that limited-savings households had higher credit-card debt and smaller retirement accounts after online betting legalization.
Balthrop argued that sports fans may overestimate their ability to beat betting markets because of their familiarity with teams and games. He called for policymakers to weigh sports-betting tax revenue against possible long-term social costs, saying the effects could extend beyond individual bettors to families and communities.
The results add a Nebraska study to the evidence on weakened household finances from online sports betting that we covered in August. Separate Kellogg School of Management research examining the 2018-23 state-by-state rollout found net investments fell by nearly 14% after legalization, while each dollar spent betting was associated with two fewer dollars placed into investment accounts.
The broader market has expanded rapidly since the Supreme Court struck down PASPA in 2018. An NBER review said about three-quarters of states had legalized online or in-person sports betting by 2026, with annual wagers exceeding $200 billion. Nebraska voters, however, rejected online sports wagering on Nov. 3, leaving betting confined to in-person wagers at the state’s horse-racetrack casinos.
