Roughly 80 million adults worldwide meet criteria for problem gambling or gambling disorder in any given year, based on prevalence rates that range from 0.1% to 6.0% of the adult population depending on the country. In the United States alone, nearly 20 million adults report experiencing at least one problematic gambling behavior “many times” in the past year, though not all of them meet the clinical threshold for addiction. These numbers have been climbing steadily since the expansion of legal sports betting in 2018.
Global and U.S. Prevalence
The World Health Organization estimates that national rates of problem gambling in the past 12 months fall between 0.1% and 6.0% of adults, with two to three times as many people experiencing less severe but still harmful gambling behaviors beneath that clinical cutoff. Countries with widespread access to casinos, online platforms, and sports betting tend to cluster toward the higher end of that range.
In the United States, the National Council on Problem Gambling’s most recent national survey found that nearly 20 million American adults report repeated problematic gambling behaviors over the past year. That figure captures a broad spectrum, from people who chase losses compulsively to those who gamble to escape stress or depression. Many fall short of a formal diagnosis but still experience real financial and emotional harm.
How Sports Betting Changed the Numbers
The 2018 Supreme Court decision that allowed states to legalize sports betting reshaped gambling in America. A UC San Diego study tracked what happened next: internet searches for help with gambling addiction, phrases like “am I addicted to gambling,” increased 23% nationally through June 2024. In some states, the spike was far steeper. Ohio saw a 67% increase in addiction-related searches after sportsbooks opened. Pennsylvania jumped 50%, Massachusetts 47%.
The pattern was consistent across states and followed a clear escalation. The arrival of physical sportsbooks triggered a 33% rise in help-seeking searches. When online sportsbooks launched, those searches surged 61%, a significantly greater and more sustained increase that persisted for years rather than fading. The convenience of betting from a phone, at any hour, appears to be the accelerant.
Young People Are at Higher Risk
Adolescents and young adults develop gambling problems at two to four times the rate of the general adult population. About 17.9% of adolescents worldwide reported gambling in the past year, with rates as high as 33.7% in North America. Ten percent of young men in the U.S. show problem gambling behavior, more than triple the adult average.
The trajectory among high schoolers is especially steep. Problem gambling among U.S. high school students doubled from 4.2% in 2018 to 8.3% in 2022, tracking alongside the expansion of legal sports betting and the explosion of gambling content on social media. In the UK, youth problem gambling doubled in a single year, from 0.7% to 1.5%, affecting an estimated 85,000 children. A 2025 student gambling survey found that 49% of college students had gambled in the past year, with 17% using student loan money to do it.
What Makes Gambling Addictive
Gambling disorder is classified alongside substance addictions for a reason: it hijacks the same brain circuitry. The brain’s reward system relies on dopamine, a chemical messenger tied to anticipation and motivation. In people who develop gambling problems, the dopamine response becomes sensitized to gambling cues, meaning the mere anticipation of placing a bet triggers a surge of activity in the brain’s reward center. Over time, gambling-related cues produce stronger dopamine responses while everyday pleasures lose their pull.
This is the same “wanting” versus “liking” distinction seen in drug addiction. A person with gambling disorder may no longer enjoy gambling, yet feel an overwhelming compulsion to do it. The brain learns to associate gambling with reward so powerfully that the urge to bet can be triggered by passing a casino, opening a phone, or even hearing a sports score. The need to gamble with increasing amounts to feel the same excitement mirrors the tolerance that develops with addictive substances.
How Gambling Disorder Is Diagnosed
A clinical diagnosis requires at least four of the following behaviors over the past year:
- Frequent thoughts about gambling, such as reliving past bets or planning the next one
- Needing to gamble with increasing amounts to achieve the same excitement
- Repeated unsuccessful attempts to cut back or stop
- Restlessness or irritability when trying to reduce gambling
- Gambling to escape problems, stress, or negative moods
- Chasing losses by returning to “get even” after losing
Four symptoms indicates a mild disorder. As the count rises, the diagnosis moves to moderate and then severe. Many people recognize these patterns in themselves long before they seek help.
Mental Health Conditions That Often Co-occur
Gambling disorder rarely exists in isolation. About half of people with a gambling disorder also have a mood disorder such as depression. Around 60% have an anxiety disorder, with panic disorder and phobias being the most common. Nearly three-quarters, 73.2%, have a co-occurring alcohol use disorder, and the rate of any substance abuse is almost seven times higher than in people who don’t gamble or who gamble recreationally.
These conditions feed each other. Depression and anxiety can drive someone to gamble as an escape, while mounting gambling losses deepen depression and anxiety. Substance use lowers inhibitions and impairs judgment around betting. Treating only the gambling behavior without addressing these overlapping conditions is one reason some people cycle through periods of recovery and relapse.
The Financial Toll
About 19% of people with gambling disorder have filed for bankruptcy, compared to roughly 5% of the general population. Those who reach that point carry an average debt between $43,000 and $53,000, though individual cases range from $5,000 to $250,000. People whose gambling leads to bankruptcy are also significantly more likely to experience job loss, marital breakdown, and legal problems.
Financial damage tends to accumulate quietly. Because gambling doesn’t produce visible intoxication or physical symptoms, many people hide their losses for months or years, draining savings, maxing out credit cards, and borrowing from family before the full picture emerges.
Treatment and Recovery Rates
Cognitive behavioral therapy is the most studied treatment for gambling disorder, and the results are encouraging. In a clinical follow-up study, 90% of patients who completed a course of CBT remained abstinent from gambling six months after treatment ended, and 95% no longer met diagnostic criteria for a gambling disorder. These are small-study numbers, and real-world outcomes vary, but they demonstrate that gambling addiction responds well to structured treatment.
CBT for gambling works by identifying the distorted thinking patterns that sustain the behavior: the belief that a win is “due,” the selective memory for wins over losses, the conviction that a personal strategy can beat the odds. Peer support programs like Gamblers Anonymous provide ongoing accountability after formal treatment ends, though attendance rates drop sharply over time. The biggest barrier to recovery isn’t treatment effectiveness. Fewer than 10% of people with gambling disorder ever seek help, making it one of the most undertreated behavioral health conditions.
