You told yourself it was entertainment. A way to make games more interesting. Maybe you put twenty dollars on a Sunday matchup, felt the thrill when your team covered the spread. The app made it so easy—bright colors, instant deposits, a notification congratulating you on your first win. Within months, you were betting during your lunch break. Then during meetings. Then at dinner with your phone hidden under the table. You found yourself calculating odds at your daughter's soccer game, refreshing the app while she asked you to watch her play.
When you finally sat across from a therapist and heard the words gambling disorder, you felt a particular kind of shame. This was supposed to be about self-control. About personal responsibility. You were an adult who made a choice to download an app. The advertising said it was entertainment, a game, a way to test your sports knowledge. But something happened between that first twenty-dollar bet and the moment you realized you had drained your retirement account. Something you could not name and could not stop.
What you did not know—what you could not have known—is that the transformation you experienced was not accidental. It was engineered. The apps you used were designed by teams who studied behavioral psychology, who tested every color and sound and notification to maximize what they called engagement and what you experienced as compulsion. And the companies behind these apps had research showing exactly what would happen to people like you.
What Happened
Gambling disorder is not about liking sports too much or being bad with money. It is a recognized psychiatric condition that changes how your brain processes risk and reward. People who develop gambling disorder describe an escalating pattern that feels like falling. What starts as occasional entertainment becomes frequent, then constant, then compulsive.
You stop being able to think about anything else. You chase losses, convinced the next bet will make you whole. You lie to your spouse about where the money went. You borrow from friends with stories about emergency car repairs or medical bills. You feel physical anxiety when you cannot place a bet—restlessness, irritability, a crawling sensation in your skin. You promise yourself you will stop after one more bet, one more day, one more win. But you cannot stop.
The financial destruction comes fast with mobile betting apps because there is no friction, no moment where you have to drive to a casino or find a bookie or withdraw cash. You can lose thousands of dollars in minutes, sitting on your couch, while your family sleeps upstairs. Many people describe a dissociative state during heavy betting sessions—hours disappear, accounts drain, and they feel like they were watching themselves from outside their body.
Relationships collapse under the weight of the lying and the financial devastation. Spouses discover drained college funds. Parents learn their adult children have lost their homes. Some people describe suicidal thoughts when they finally confront the full scope of what they have lost. This is not entertainment that went a little too far. This is a clinical addiction with documented neurological changes and a pattern that physicians now recognize as predictable.
The Connection
Mobile sports betting apps were engineered using the same behavioral psychology techniques that make social media and video games addictive, but applied to an activity—gambling—that has known addiction potential. The combination created what researchers call a supernormal stimulus: something that hijacks brain chemistry more powerfully than the natural behavior it mimics.
Traditional sports betting required planning and friction. You had to go somewhere, interact with a person, handle physical money. These small barriers gave your prefrontal cortex—the part of your brain responsible for judgment and impulse control—time to engage. Mobile betting apps eliminated all friction. They made betting instantaneous, private, and available twenty-four hours a day.
The specific features that drive gambling disorder are well documented in scientific literature. Variable ratio reinforcement schedules—where wins come at unpredictable intervals—create more compulsive behavior than any other reward pattern. Research published in the journal Addiction in 2019 found that mobile gambling apps incorporated these schedules deliberately, along with near-miss features that make losses feel almost like wins, activating the same dopamine pathways.
A 2020 study in the Journal of Behavioral Addictions documented that mobile betting apps use push notifications timed to moments of high vulnerability—late at night, during known sporting events, immediately after a loss. These notifications include free bet offers and odds boosts that create artificial urgency. The study found that users who enabled notifications had three times the rate of gambling disorder compared to those who disabled them.
Researchers at the University of British Columbia published findings in 2021 showing that the in-play or live betting features—where you can bet on individual plays during a game—produce significantly higher addiction rates than traditional pre-game betting. The constant opportunity to chase losses or double down creates a cycle that mirrors the rapid-fire reinforcement of slot machines, which have the highest addiction rate of any gambling format.
The apps also incorporated social features—leaderboards, sharing wins, following other bettors—that normalize excessive gambling and create peer pressure to continue betting. They gamified the experience with achievement badges and loyalty tier systems that reward heavy use. These are not features that emerged accidentally. They are the product of deliberate design decisions informed by research into behavioral psychology and addiction pathways.
What They Knew And When They Knew It
DraftKings executives were briefed on gambling addiction risks before the company expanded from daily fantasy sports into sports betting. Internal documents from 2018 show that the company conducted user research that identified a segment of high-value customers they tracked as heavy users who displayed patterns consistent with problem gambling—chasing losses, betting beyond their means, logging in at all hours.
Rather than implementing meaningful safeguards, the company focused on how to extract maximum revenue from these users. A 2019 internal presentation identified heavy users as representing over 60 percent of revenue despite being less than 10 percent of users. The presentation included strategies for increasing engagement among these users through personalized offers and targeted notifications.
FanDuel commissioned research in 2017 from a team of behavioral psychologists that documented which app features created the most compulsive use. The research tested notification frequency, bonus offer structures, and interface design elements. The findings showed that certain features—particularly loss-triggered promotions and mid-game betting opportunities—significantly increased the time and money users spent on the platform. FanDuel implemented all of the highest-performing features in its app design.
BetMGM had access to decades of research from its parent company MGM Resorts on casino gambling addiction. MGM had internal responsible gambling protocols for its physical casinos, including training for staff to identify problem gamblers and systems to allow self-exclusion. When BetMGM launched its mobile app in 2018, it did not implement equivalent digital safeguards. There were no limits on betting frequency, no meaningful verification of deposit source, and no proactive intervention for users showing compulsive patterns.
All three companies had access to published research showing elevated addiction rates for mobile gambling. A widely cited study from the UK Gambling Commission published in 2016 found that online gambling had double the problem gambling rate of in-person gambling. Research from Australia published in 2017 showed that mobile betting apps specifically had the highest rates of gambling disorder among all formats, with nearly 15 percent of regular users meeting clinical criteria for addiction.
The companies also knew about the specific vulnerability of sports betting to a phenomenon researchers call the illusion of control. Because sports betting involves knowledge and analysis—unlike pure chance games—bettors believe they have more control over outcomes than they actually do. This illusion makes sports betting particularly prone to chasing behavior and persistent gambling despite losses. Research documenting this effect was published in the Journal of Gambling Studies in 2015, years before these companies launched their mobile betting platforms.
State regulatory filings show that DraftKings and FanDuel both submitted responsible gambling plans as part of their licensing applications in multiple states between 2018 and 2020. These plans included language about self-exclusion tools and deposit limits. However, internal metrics documents show that the companies tracked what percentage of users ever accessed these tools—consistently less than 2 percent—and made no efforts to increase awareness or usage. The tools existed to satisfy regulators, not to reduce harm.
How They Kept It Hidden
The sports betting industry funded a network of academic research programs and partnerships with universities that produced studies minimizing addiction risks or emphasizing personal responsibility frameworks. These industry-funded studies consistently found lower rates of problem gambling than independent research.
DraftKings established partnerships with multiple universities starting in 2019, providing funding for research centers and academic positions. These partnerships came with advisory board positions for company executives and, in some cases, contractual approval rights over publication of findings. A 2021 investigation by the Chronicle of Higher Education documented how these arrangements created conflicts of interest that shaped research conclusions.
The companies hired many of the same public relations and lobbying firms that had previously worked for tobacco and pharmaceutical companies. These firms specialized in manufacturing doubt about addiction science and promoting narratives about personal choice and freedom. Internal strategy documents from one such firm, obtained through discovery in regulatory proceedings, outlined plans to amplify voices of recreational bettors while marginalizing addiction researchers and treatment advocates.
The industry created and funded front groups with names like the Coalition for Responsible Gaming and the American Gaming Association that positioned themselves as balanced stakeholders but advocated consistently against meaningful regulation. These groups testified before state legislatures considering sports betting legalization, providing assurances about minimal addiction risk and the adequacy of voluntary safeguards.
When early reports of gambling addiction clusters began appearing in states that legalized mobile betting, the companies responded with settlement agreements that included broad non-disclosure provisions. People who sued over gambling losses or addiction were offered settlements contingent on signing NDAs that prevented them from speaking about their experiences or the company practices that contributed to their addiction.
The companies also exploited regulatory fragmentation. Sports betting is regulated at the state level, with different rules and oversight capacity in each jurisdiction. The companies used this patchwork system to avoid comprehensive scrutiny, implementing minimal safeguards in states with weak oversight while lobbying against stronger measures in states considering tighter regulation.
Why Your Doctor Did Not Tell You
Gambling disorder has been recognized in the Diagnostic and Statistical Manual of Mental Disorders since 1980, but most primary care physicians receive no training in identifying or treating it. Medical school curricula focus on substance use disorders, and gambling disorder is rarely mentioned outside of psychiatry rotations.
When sports betting apps launched nationally starting in 2018, there was no public health campaign to educate physicians about the new risk. Unlike prescription medications that come with FDA warnings and required patient counseling, there was no system to alert doctors that their patients now had instant access to a product with significant addiction potential.
The sports betting companies did not provide educational materials to physicians. Instead, they spent billions on advertising that framed betting as entertainment and a test of sports knowledge. This advertising saturated sports media and presented betting as a normal part of being a sports fan. Many physicians, if they thought about it at all, absorbed the same messaging as the general public.
Professional medical associations were slow to respond to the emerging crisis. The American Medical Association did not issue guidance on sports betting addiction until 2022, four years after widespread legalization. By that point, millions of people had developed gambling disorders. The delay meant that most physicians had patients suffering from gambling disorder without recognizing the symptoms or knowing how to screen for the condition.
Mental health professionals were better positioned to identify gambling disorder, but many people never made it to a therapist. The shame and secrecy that accompany addiction meant people hid their gambling until the financial consequences forced exposure. By then, the disorder was severe and the harm extensive.
There was also no screening infrastructure. Primary care offices routinely screen for depression, alcohol use, and tobacco use because there are standard protocols and reimbursement codes for these activities. No such system existed for gambling disorder. Even physicians who suspected a problem often had no clear referral pathway for treatment, as specialized gambling addiction treatment remained rare and poorly covered by insurance.
Who Is Affected
The clearest qualifying factor is development of gambling disorder following use of mobile sports betting apps. If you began using DraftKings, FanDuel, BetMGM, or similar platforms and then experienced a pattern of escalating gambling behavior that caused financial harm, relationship damage, or psychological distress, you may be affected.
The specific pattern typically looks like this: You started betting relatively small amounts on familiar sports. The activity felt controlled and recreational initially. Over weeks or months, you found yourself betting more frequently—not just on games you planned to watch but on games you had no interest in, on sports you knew nothing about, during times you previously would not have gambled.
You increased the amounts you were betting. What started as ten or twenty dollars per bet became hundreds or thousands. You found yourself chasing losses—trying to win back money you had lost by placing larger or riskier bets. You may have had big wins that briefly restored your balance, but you kept betting rather than stopping, and eventually lost it all back plus more.
You started lying about your gambling. You hid your phone when betting. You made excuses for missing money. You may have opened new credit cards or taken loans without telling your spouse. You felt shame and anxiety about your gambling but could not stop. You may have tried to quit multiple times and found yourself reinstalling the app within days or hours.
The financial harm varies but is often severe. Many people report losses of tens of thousands or hundreds of thousands of dollars. Drained retirement accounts, refinanced homes, maxed credit cards, borrowed money from family and friends. Some people lost their jobs due to gambling at work or from the distraction and stress of mounting losses.
The timeframe matters less than the pattern. Some people developed severe gambling disorder within months of first using betting apps. Others had a year or more of seemingly controlled use before something shifted and they lost the ability to stop. Both patterns reflect the same underlying product design and company conduct.
You do not need to have been formally diagnosed with gambling disorder to be affected. Many people only received a diagnosis after seeking help for depression, anxiety, or relationship problems that were rooted in their gambling. If you recognize the pattern—escalating use, loss of control, continued gambling despite harm—you are describing gambling disorder regardless of whether a physician has used those specific words.
Age and prior gambling history are not disqualifying factors. Many of the people most severely affected were adults in their thirties, forties, and fifties with no history of problem gambling. They were professionals with stable careers, parents with families, people who had never been inside a casino. The accessibility and design of mobile betting apps created gambling disorders in people who would never have developed them from traditional gambling formats.
Where Things Stand
Multiple lawsuits have been filed against DraftKings, FanDuel, and BetMGM alleging that the companies employed deceptive practices, failed to implement adequate safeguards, and deliberately designed their platforms to create addictive behavior. These cases are in various stages of litigation across multiple state and federal courts.
In Massachusetts, a class action lawsuit filed in 2023 alleges that DraftKings violated state consumer protection laws by marketing to vulnerable populations and failing to disclose addiction risks. The case survived a motion to dismiss in early 2024, with the judge finding that the plaintiffs had adequately alleged deceptive conduct and harm. Discovery is ongoing, with plaintiffs seeking internal company documents about app design decisions and user research.
A lawsuit filed in New York in 2023 makes similar claims against multiple betting platforms, arguing that the companies created a public nuisance by knowingly deploying addictive products without adequate warnings or safeguards. That case is also in the discovery phase, with particular focus on what the companies knew about addiction risks and when they knew it.
Individual lawsuits have been filed in Illinois, Pennsylvania, New Jersey, and other states where mobile sports betting is legal. These cases typically allege negligence, fraud, and violations of state consumer protection statutes. Some plaintiffs are seeking damages for financial losses and emotional distress. Others are pushing for injunctive relief that would force the companies to redesign their apps and implement meaningful protections.
There has not yet been a major settlement or verdict in these cases, but the litigation is accelerating. As discovery produces internal documents, the factual record of what companies knew and when they knew it continues to grow. Legal experts familiar with the cases expect that as this evidence becomes public, additional plaintiffs will come forward and pressure for settlement will increase.
The legal theories in these cases draw on successful litigation against other industries that knowingly sold addictive products. Tobacco litigation established that companies can be held liable when they have internal research showing their products cause harm but market them as safe. Opioid litigation reinforced that companies have a duty not to employ marketing tactics they know will lead to addiction and cannot hide behind claims of personal responsibility when they have deliberately engineered compulsive use.
State attorneys general in several jurisdictions have also opened investigations into sports betting company practices. These regulatory actions focus on advertising to minors, failure to honor self-exclusion requests, and inadequate problem gambling resources. While these are separate from private litigation, they are building a public record of company misconduct that supports civil claims.
The timeline for resolution remains uncertain. Complex litigation against large corporations typically takes years from initial filing to settlement or trial. However, the pace is faster than in previous product liability cases because the harm is recent and ongoing, the user base is large, and the documentary evidence is digital and extensive. Attorneys involved in the cases have indicated they expect significant developments within the next eighteen to twenty-four months.
New cases can still be filed. Most states have statutes of limitation for personal injury and consumer protection claims that run for multiple years from the date of harm or from when the plaintiff discovered the harm. People who developed gambling disorder from betting apps within the past several years are still within the window to bring claims.
You watched the commercials during every football game. You heard the professional gamblers explain their betting strategies. You saw the celebrity endorsements. The apps were legal, regulated, advertised everywhere. You were supposed to believe this was a normal consumer product, no different from buying a lottery ticket or playing poker with friends.
But this was not a game. It was a product engineered by teams who studied addiction pathways and implemented every feature that research showed would make you unable to stop. The companies behind these apps had data showing what would happen to people like you. They had research documenting the addiction rates, the financial devastation, the families destroyed. They saw the pattern in their own user data—small numbers of heavy users generating most of the revenue, logging in at three in the morning, depositing more money the same day they withdrew winnings.
They knew. They decided the profit was worth it. They designed the apps to maximize compulsive use. They fought regulation that would reduce harm. They hid behind language about responsible gambling while ensuring the vast majority of users never saw or used any protective tools. What happened to you was not bad luck. It was not a moral failing. It was the documented result of business decisions made by people who had the research in front of them and chose profit over safety.
You were not supposed to be able to stop. That was the design. And what they built, what they knew, what they hid—all of that is now part of the record. The truth of what happened is no longer something you carry alone in shame. It is written in internal emails and user research reports and behavioral psychology studies. It is documented. And it was always their knowledge and their choice, not your weakness.
