U.S. sportsbooks projected breaking gambling records, $4 billion bet on 2026 NCAA basketball's March Madness.

Gambling is common in adolescent boys, with more than a third of them gambling before 18

Greater sports-betting severity is tied to increased depression, anxiety, distress, loneliness, and stress.

Gambling, especially among Gen Z, poses urgent risks extending beyond entertainment. March Madness brings the issue into sharp focus. U.S. legal sports betting handle now exceeds $120–150 billion annually.

March Madness is one of the busiest periods for on-site and online sports betting in the United States. While the Super Bowl remains the most wagered-on single event, the NCAA men’s basketball tournament is widely considered the most bet-on event. U.S. sportsbooks will take approximately $4 billion in bets during the 2026 tournament, an increase over prior years. When including prediction markets, total March Madness wagering may approach $4.5 billion, according to recent estimates.

The growth in sports betting is spurred by Gen Z and Millennials, who increasingly engage in high-risk sports betting, stock trading, and cryptocurrency speculation on mobile devices. Mobile betting accounts for about 85–90% of wagers. Gambling is common among adolescents, too, with substantial proportions reporting participation before age 18.

Once an adult activity linked to casinos and racetracks, sports gambling is now a continuous, socially normalized part of daily life for many young men—especially during March Madness, when sports consumption and gambling are inseparable.

Early Introduction: Adolescence as the Entry Point

One of the most concerning aspects of this phenomenon is the early onset, gateway exposure. The age of first exposure is decreasing. Gambling is no longer an activity that begins in adulthood; it is increasingly introduced in early adolescence, particularly among boys.

National survey data indicate that 36% of boys aged 11–17 report gambling within the past year, with prevalence increasing from 28% among boys ages 11–13 to 44% among those ages 15–17. By late adolescence, nearly half report some form of gambling activity.

Importantly, early gambling is not benign. Even in adolescence, some individuals report stress, interpersonal conflict, and signs of compulsive behavior. The early patterns of risk-taking, reward-seeking, and normalization of betting persist into young adulthood. The social transmission of gambling activities is especially alarming: Among boys with gambling friends, participation rates exceed 80%, compared to under 20% for those whose friends do not gamble.

Surveys show that approximately 60% of adolescents report seeing gambling advertisements on social media, often at high frequency. Pervasive ads and social media gaming environments act as gateway exposures for youth.

Gen Z often views sports betting as a social activity, done with friends, and it often pairs with binge drinking (ages 18-29), creating a "compounded risk" environment in which digital betting and heavy alcohol consumption happen simultaneously.

Microbetting (in-play wagers on individual plays), where bets occur every few seconds/minutes, is now common. It dramatically increases risks and also addictiveness. Microbetting resembles casino slot-machine reinforcement schedules, enhancing loss of control and compulsivity.

Transition to Young Adulthood: Experimentation to Normalization

As individuals enter college and early adulthood, gambling shifts from experimental to normative behavior. National surveys show that among adults under age 30, participation rates approach 30–40%. In colleges, however, more than half report engaging in sports betting, with rates among on-campus students estimated to exceed two-thirds of students.

Young men are the epicenter of this shift. They are more likely than women to participate, bet more frequently, and engage in higher-risk wagering. The patterns include repeated betting, use of multiple platforms, and chasing losses—the erroneous belief that continued gambling will recover prior losses, which reinforces the repetitive cycle of engagement.

Structural changes in the gambling environment are responsible for this shift. The vast majority of bets are placed online, extending the reach of betting to younger populations. And where once sports gambling was an episodic activity, it is now always accessible, as mobile platform grant continuous access, rapid wagering, and immediate feedback, which appeal to sensation-seeking and risk-taking, activities that that are more prevalent in males.

Mechanisms: Neurobiology and Platform Design

The disproportionate effect of gambling on young men is both behavioral and neurobiological. Gambling activates reinforcement pathways similar to those involved in substance use disorder, involving dopamine signaling, and reinforces behavior through expectation and reward.

Modern sports betting platforms magnify such vulnerabilities. Features like in-play wagering and microbetting create relentless opportunities, while variable rewards and rapid feedback aggressively lock users into repeated betting. Such design is not accidental; it drives App stickiness, habit formation, sustained use—and quickly leads to behavioral addiction, defined by loss of control and persistent harm.

In adolescents and emerging adults, the involved systems are especially sensitive. The prefrontal cortex—responsible for impulse control and risk evaluation—continues maturing into the 30s. The cortical immaturity creates an imbalance in which reward-seeking outpaces regulatory control, amplifying vulnerability to high-risk behaviors and compounding the effects of platform design.

Given such vulnerabilities, college students develop gambling problems at roughly twice the rate of the general adult population. What's more, sports gamblers are at least 1.9 times more likely to binge drink (4 or more drinks for women, 5 or more for men, in one sitting) than non-gamblers.

Advertising and Media Integration

The media environment itself also plays a role in promoting gambling, especially among adolescents and young adults. Gambling is increasingly normalized through its integration into sports with live odds, in-game promotions, and real-time prompts.

Advertising exposure is associated with higher betting frequency, increased spending, and riskier behavior, and may encourage the use of “buy now, pay later” or the borrowing funds leading to the accumulation of credit card debt.

Promotional “free bets” and “risk-free wagers” can be misleading, particularly for younger users. Influencers and athletes further reinforce an association between gambling and sports fandom.

Among Gen Z, sports betting is part of a broader convergence with speculative financial behaviors, including options trading and cryptocurrency,. All these activities share core characteristics such as variable reward structures, high volatility, gamified interfaces, and peer-driven social amplification that reinforce risk-taking and compulsive engagement.

Clinical and Behavioral Consequences

Among college students, approximately 6% meet established criteria for pathological gambling and an additional 10% exhibit problem gambling behaviors, according to recent clinical surveys. Alarmingly, these rates are higher than those observed in older adult populations based on comparative studies. In addition, longitudinal studies show sports gambling is linked with subsequent alcohol-related problems, indicating the overlap with behavioral and substance addictions.

Gambling in young adults is associated with academic impairment, monetary difficulties, strained interpersonal relationships, depression, anxiety, higher rates of suicidal ideation, and substance use disorders.

March Madness as a High-Intensity Exposure Event

March Madness represents a concentrated example of modern gambling dynamics. The tournament combines high emotional involvement, dense scheduling, and widespread social participation, creating conditions that promote rapid betting escalation. Multiple games occur simultaneously, permitting continuous wagering, while unpredictable outcomes and social contexts—such as watch parties and bracket competitions—normalize participation.

More broadly, continuous exposure is the norm. Gambling is now ever-present, reinforced by internet platforms, media integration, and advertising—strengthening conditioned associations and increasing compulsive behavior.

Public Health Implications and Clinical Gaps

Constant 24/7 exposure and game-like betting platforms fuel engagement through rapid feedback, unpredictable rewards, and constant temptation.

Red flags of a developing gambling disorder include preoccupation with betting, pursuing losses, financial difficulties, academic decline, and co-occurring psychiatric symptoms. Early identification is critical, as intervention during the initial stages may prevent progression to a more severe disorder.

Gambling disorder is associated with one of the highest suicide attempt rates among behavioral addictions, and the risk is especially elevated in young men experiencing financial loss and depression. Screening by a pediatrician or other healthcare provider is virtually nonexistent.

Sports betting is an increasingly common activity; 60% of students report engaging in sports betting, and 4% do so daily. Early life exposure, mobile 24/7 access, sports/stocks/crypto engagement, binge drinking, and modern campus culture have all contributed to the rise of gambling addiction.

College students develop gambling problems at roughly twice the rate of the general adult population. Recent studies suggest that more than 15% of college students experience some degree of gambling-related harm, and one 2025 report found that 17% were at high risk and 29% at moderate risk.
