The landscape of American sports culture has undergone a seismic shift since the federal ban on sports wagering was overturned in 2018, and new data reveals that the momentum of the industry shows no signs of slowing. According to the latest Annual Sports Fanship Survey conducted by the Siena Research Institute (SRI) in collaboration with St. Bonaventure University’s Jandoli School of Communication, over a quarter of all American adults (27%) now maintain an active online sports betting account. This figure represents a significant upward trajectory from previous years, reflecting the rapid normalization of gambling within the national pastime.
The survey, which polled 3,084 individuals across the United States, highlights a particularly sharp concentration of activity among younger men. More than half of men aged 18 to 49 (52%) reported having an active online betting account, making this demographic the primary engine of the industry’s growth. However, this surge in participation is accompanied by a growing list of concerns regarding financial risk, psychological health, and the integrity of professional and collegiate sports.
A Steady Climb: The Evolution of Participation Since 2024
The growth of the online sports betting market has been consistent and measurable over the last three years. In 2024, the SRI/St. Bonaventure poll found that 19% of Americans held active betting accounts. That number rose to 22% in 2025 and has now reached 27% in 2026. This represents an 8-percentage-point increase in just two years, a growth rate that underscores the effectiveness of aggressive marketing campaigns and the continued legalization of sports betting in new state jurisdictions.
While the number of account holders has grown, the intensity of their activity has remained high. Among those with active accounts, 83% reported placing bets regularly, a figure consistent with the previous year. When looking at the total American population, 22% of all adults and nearly half of men in the 18-49 bracket (46%) identify as "active" bettors.
Don Levy, the Director of the Siena Research Institute, noted that the data points to gambling becoming an "active part of life" for a massive segment of the population. He observed that the shift from one-in-five Americans having an account to one-in-four marks a pivotal moment in the social acceptance and accessibility of these platforms.
The Financial and Psychological Risks of the Betting Boom
As the volume of bettors increases, so too do the indicators of problem gambling. One of the most alarming findings in the 2026 survey is the prevalence of "chasing losses"—the practice of placing additional bets in an attempt to recoup money already lost. Sixty percent of active bettors admitted to this behavior, which experts often cite as a primary precursor to significant financial distress and gambling addiction.
The financial stakes are also rising. The poll revealed that 63% of respondents had wagered $100 or more in a single day, an increase of 7 percentage points over 2025. This suggests that bettors are not only participating more frequently but are also increasing the size of their stakes. The allure of high-risk, high-reward wagering is a significant factor; 83% of participants said they enjoy betting on parlays or futures, which offer larger payouts but carry much lower odds of success.
The human cost of this growth is becoming more visible in the survey’s social metrics. Nearly one-third of bettors (31%) reported being confronted by friends or family members about their use of online sportsbooks, a substantial jump from the 23% reported the previous year. Additionally, 27% of bettors admitted to lying to others about the extent of their gambling behavior.
The emotional toll is equally evident, with 42% of bettors acknowledging they bet more than they should and 43% reporting feelings of shame or guilt after losing a wager. Perhaps most tellingly, the percentage of bettors who have sought help through a problem gambling helpline or other support services has spiked to 15%, up from 9% in the prior year. This increase suggests that while more people are entering the market, a growing subset is finding the experience unmanageable.
Public Sentiment: A Mandate for Regulation
Despite the popularity of sports betting, there is a clear and growing consensus among the American public that the industry requires stricter oversight. While 50% of those polled believe that sports betting should be legal in all 50 states, this support for legality is conditional on the implementation of robust "guardrails."
A significant majority of Americans (67%) now believe the federal government should "aggressively regulate" online sports betting to protect consumers from compulsive gambling. This represents a shift toward a more centralized regulatory approach, possibly in response to the patchwork of state laws that currently govern the industry.
Specific areas of concern include:
- Age Limits: 74% of respondents view the legality of 18-year-olds wagering on sports as a serious issue. Even among the 18-34 demographic, 69% expressed concern over the minimum age requirements.
- Advertising: The omnipresence of sportsbook commercials during live broadcasts has become a point of contention. Over half of the respondents (53%) support a total ban on sportsbook advertising during game broadcasts, and 48% believe that the frequent mention of betting odds by sports analysts is detrimental to the sports-watching experience.
- College Sports: There is a notable discomfort with betting on collegiate athletics, with many respondents favoring tighter restrictions to protect student-athletes from the pressures of the gambling market.
Integrity Concerns and the Corruption of Sport
The intersection of gambling and athletic performance has raised fears about the long-term integrity of organized sports. The survey found that 56% of participants believe online betting will eventually corrupt the sports they love. These fears are not unfounded, as recent years have seen high-profile scandals involving alleged insider betting schemes and players violating league gambling policies.
The NCAA’s recent rule changes, which allow certain personnel and players to bet on professional sports, were met with skepticism; 51% of respondents called the move a "bad idea." Furthermore, the public remains highly concerned about the potential for "spot-fixing" or the manipulation of specific game events for gambling purposes, especially following allegations involving NBA players and staff.
Dr. Brian Moritz, an associate professor at St. Bonaventure University, characterized legal and accessible gambling as the "defining issue" for the sports world in the 2020s. He noted that while fans appreciate the entertainment value, there is a "complicated relationship" at play. Fans are increasingly wary of the lack of boundaries and are signaling a desire for the industry to be treated with the same level of caution as other adult-oriented industries.
The Rise of Prediction Markets
Beyond traditional sports betting, the survey also explored the emerging field of prediction markets. Platforms like Polymarket and Kalshi, which allow users to wager on the outcomes of political elections, economic indicators, and other real-world events, are gaining traction.
The poll found that 15% of Americans have used these platforms to wager on "sports contracts." This participation is much higher among specific groups, with 42% of "avid sports fans" and 33% of men aged 18-49 engaging with prediction markets. Despite the novelty of these platforms, the public’s stance on regulation remains consistent: 65% of Americans believe prediction markets should be subject to the same state-level regulations as traditional sports betting. Among younger men, that number rises to 73%.
Implications for the Future of the Industry
The data from the 2026 Annual Sports Fanship Survey presents a double-edged sword for the gambling industry. On one hand, the market is expanding at a rapid clip, with high engagement and a solid base of active users. On the other hand, the industry is facing a "crisis of conscience" from the public.
The significant increase in people seeking help for problem gambling, combined with the rise in social friction (confrontations and lying), suggests that the current "responsible gaming" initiatives may be insufficient. The jump in help-seeking behavior from 9% to 15% is particularly striking, indicating that the infrastructure for support must expand at the same rate as the betting platforms themselves.
For legislators and league officials, the message from the public is clear: legality does not equal a free-for-all. The demand for federal regulation, advertising bans, and higher age limits suggests that the next phase of the sports betting evolution will likely be defined by a push for more restrictive policies. As the 2020s progress, the challenge for the industry will be balancing its massive profitability with the social responsibility required to maintain public trust and protect the most vulnerable participants.
