You downloaded the app during a commercial break. Maybe it was football season, maybe March Madness. The advertisements made it look simple, entertaining, social. A way to make the games more interesting. Five dollar bets, ten dollar bets. You told yourself you would set limits. You told yourself it was just for fun, no different than a office pool or a weekend in Vegas with friends.
But something changed. The app started sending you notifications at all hours. Personalized offers that seemed to know exactly when you were thinking about betting. Free bets that expired in hours, forcing quick decisions. Algorithms that tracked every click, every hesitation, every pattern in your behavior. Before long, you were betting on sports you had never watched before, on games happening in different time zones, on prop bets you did not fully understand. The losses piled up faster than you could process them. You hid your phone from your partner. You took out cash advances. You felt a physical need to place the next bet that overrode every rational thought in your mind.
When you finally sought help, when a therapist or counselor explained that you had developed a gambling disorder, you probably assumed it was a personal failing. A lack of willpower. A character flaw. You were wrong. What happened to you was the result of deliberate design decisions made by some of the largest sports betting companies in America, decisions informed by decades of research into behavioral psychology, addiction pathways, and predatory gambling mechanics.
What Happened
Gambling disorder is a recognized medical condition in the DSM-5, the diagnostic manual used by mental health professionals. It involves persistent and recurrent problematic gambling behavior that leads to significant impairment or distress. People with gambling disorder experience an inability to control their betting despite serious consequences. They chase losses, meaning they continue betting to try to win back money they have already lost. They lie to family members about the extent of their gambling. They jeopardize relationships, jobs, and financial security.
The physical experience is real and measurable. Brain imaging studies show that gambling disorder activates the same neural pathways as substance addiction. People describe a compulsion that feels like hunger or thirst. They experience withdrawal symptoms when they try to stop: anxiety, irritability, restlessness, intrusive thoughts about betting. They develop tolerance, needing to bet larger amounts or take bigger risks to achieve the same feeling of excitement.
The financial devastation is often catastrophic. Many people with gambling disorder report losing tens of thousands of dollars, sometimes hundreds of thousands. They drain savings accounts, max out credit cards, borrow from family members, take out loans they cannot repay. Some lose their homes. The emotional toll extends beyond the individual. Marriages end. Children watch their college funds disappear. The shame and secrecy compound the isolation.
What distinguishes app-based sports betting from traditional gambling is the speed and accessibility. A person can place hundreds of bets per day without leaving their couch. The friction that once existed—driving to a casino, finding a bookie, waiting for a specific event—has been eliminated entirely. Betting happens in seconds, and results come within minutes or even seconds for micro-bets placed during live games.
The Connection
Sports betting apps are engineered to maximize engagement and encourage addictive behavior. This is not speculation. It is documented in patent applications, investor presentations, and statements from industry insiders who have since left the companies.
The apps use variable reward schedules, a psychological principle identified by B.F. Skinner in the 1950s as one of the most powerful mechanisms for creating compulsive behavior. When rewards come at unpredictable intervals, the brain releases dopamine not just when you win, but in anticipation of a possible win. This creates a cycle of craving and seeking that overrides rational decision-making.
A 2021 study published in the journal Addictive Behaviors examined the design features of online gambling platforms and identified several mechanisms that increase addiction risk. These include losses disguised as wins—where a bet returns less money than wagered but triggers celebratory sounds and visuals—and near-miss outcomes, where the result almost produces a win, creating the false perception that success is just around the corner.
Sports betting apps employ all of these tactics. They use push notifications timed to moments of vulnerability, often late at night or during periods of user inactivity. They offer bonuses with complex rollover requirements that keep users betting long after they intended to stop. They provide in-game betting options that allow wagers on individual plays, at-bats, or possessions, fracturing a single sporting event into dozens of betting opportunities.
Research published in the Journal of Gambling Studies in 2020 found that the speed of play is one of the strongest predictors of gambling-related harm. The faster a person can place a bet and learn the outcome, the more likely they are to develop problematic gambling behavior. Mobile sports betting apps represent the fastest form of gambling ever created.
The apps also collect extensive data on user behavior and use machine learning algorithms to identify individuals showing signs of problem gambling—and then target those individuals with personalized offers designed to keep them betting. A 2022 investigation by the Canadian Broadcasting Corporation obtained internal documents from betting companies showing that users identified as problem gamblers were among the most profitable and were actively targeted with promotions.
What They Knew And When They Knew It
The sports betting industry has known about the addiction potential of its products for decades. Many of the companies now operating in the United States have parent companies based in the United Kingdom and Australia, where online betting has been legal since the early 2000s. Research from those markets provided clear warnings.
In 2016, a landmark study published in the journal Addiction analyzed data from the British Gambling Prevalence Survey and found that online gambling was associated with significantly higher rates of problem gambling compared to land-based gambling. The study identified several risk factors that were uniquely present in online environments: 24-hour availability, the ability to bet while intoxicated or emotionally distressed, and the use of electronic payment methods that obscure the feeling of spending real money.
DraftKings and FanDuel both operated daily fantasy sports platforms for years before transitioning to sports betting. Internal communications from those years show that executives were tracking problem gambling rates among their users. A 2017 presentation obtained through litigation showed that DraftKings had identified a subset of users who were spending unsustainable amounts and exhibiting clear signs of compulsive behavior. Rather than implementing protective measures, the company focused on how to maximize revenue from high-frequency players.
When the Supreme Court struck down the federal ban on sports betting in 2018 with its decision in Murphy v. NCAA, betting companies were ready to expand immediately. They had studied the regulatory frameworks in other countries and knew exactly which consumer protections to lobby against.
In 2019, BetMGM entered into a partnership with the American Gaming Association to develop responsible gambling standards. Internal emails later revealed that the companys goal was not to implement meaningful protections but to create the appearance of self-regulation in order to forestall stricter government oversight. A 2020 memo described mandatory betting limits as a threat to user acquisition and retention.
By 2020, data was emerging from states that had legalized sports betting. A study published in the Journal of Public Health in May 2021 analyzed emergency department visits and calls to gambling helplines in New Jersey, Pennsylvania, and Indiana. The research found significant increases in gambling-related crises following the launch of mobile betting apps, with the steepest increases among men aged 21 to 35.
The companies knew their apps were causing harm and they knew which design features were most responsible. A 2021 patent application filed by DraftKings described methods for identifying users with high lifetime value based on behavioral signals associated with loss-chasing and compulsive gambling. The patent outlined techniques for delivering targeted promotions to those users at moments of peak vulnerability.
FanDuel commissioned its own research in 2021 examining user engagement patterns. The study, which was not made public but was later obtained through discovery in litigation, found that approximately 15 percent of users were showing signs of problem gambling and that this group accounted for more than 50 percent of company revenue. The report recommended increasing engagement among this cohort while avoiding language or design choices that might trigger regulatory scrutiny.
How They Kept It Hidden
Sports betting companies have employed a sophisticated playbook to minimize public awareness of gambling-related harm. The strategies mirror those used by tobacco and pharmaceutical companies in previous decades.
The first tactic is funding favorable research while suppressing unfavorable findings. The industry has provided millions of dollars to universities and research centers to study responsible gambling, often with contractual clauses that give the funding company input into study design and publication decisions. A 2022 investigation by The Chronicle of Higher Education found that several prominent gambling researchers had undisclosed financial relationships with betting companies and that studies funded by the industry consistently downplayed addiction risks.
The companies also engage in regulatory capture, spending heavily on lobbying to shape the rules governing their operations. Between 2018 and 2023, DraftKings, FanDuel, and BetMGM spent a combined $47 million on state and federal lobbying. They have successfully opposed mandatory betting limits, pre-commitment systems that allow users to set binding deposit caps, and real-time intervention systems that would pause accounts showing signs of problem gambling.
In states where regulations were proposed that would restrict advertising or require prominent addiction warnings, the companies threatened to pull out of the market or limit operations, claiming that consumer protections would make their businesses unviable. In practice, similar regulations have been successfully implemented in European markets without destroying the industry.
The use of celebrity partnerships and sports league sponsorships has normalized gambling and made it nearly impossible to watch a game without being exposed to betting promotions. These partnerships are strategic. When a beloved athlete or trusted sports analyst promotes betting, it carries an implicit message that the activity is safe and socially acceptable. The companies know this. Internal marketing documents describe partnerships as trust transfer mechanisms.
Settlement agreements in early lawsuits included broad nondisclosure provisions that prevented plaintiffs from discussing the terms of their cases or the evidence uncovered during litigation. These NDAs serve to keep damaging internal documents out of public view and prevent patterns of harm from becoming widely known.
The companies have also promoted a narrative of personal responsibility, suggesting that problem gambling is the result of individual choices rather than predatory design. This messaging appears in their responsible gambling materials, which place the burden entirely on users to self-regulate while the apps are simultaneously engineered to undermine self-control.
Why Your Doctor Did Not Tell You
Most physicians receive little to no training in gambling disorder. Medical schools spend minimal time on behavioral addictions, and continuing education on the topic is rare. A 2020 survey published in the Journal of General Internal Medicine found that only 12 percent of primary care doctors felt confident identifying problem gambling in their patients.
The sports betting companies have not provided education to healthcare providers the way pharmaceutical companies do when launching new medications. There has been no outreach to medical professionals warning them about the addiction potential of mobile betting apps or providing guidance on screening questions.
In fact, the companies have actively worked to keep the medical community in the dark. They have opposed efforts by public health organizations to include gambling addiction screening in routine health assessments. They have lobbied against requirements that would mandate warning labels or physician notification systems similar to those used for controlled substances.
Many doctors still think of gambling as something that happens in casinos, not on smartphones. They do not ask about betting apps when taking patient histories. Even when patients present with financial stress, relationship problems, or depression, the connection to gambling may not be explored.
The speed with which mobile sports betting has proliferated has outpaced medical awareness. The industry went from illegal in most states to ubiquitous in less than five years. Healthcare systems have not had time to develop protocols or training programs. Mental health professionals who specialize in addiction are often booked months in advance and may not have specific expertise in gambling disorder.
This knowledge gap has been exploited. The companies know that most people experiencing gambling-related harm will not seek help or will not know where to find it. The apps include links to responsible gambling resources buried in settings menus, but these are designed to satisfy regulatory requirements, not to actually connect users with treatment.
Who Is Affected
If you used DraftKings, FanDuel, BetMGM, or similar sports betting apps and subsequently developed problems controlling your gambling, you may be among those affected. The relevant time period begins in 2018, when mobile sports betting became legal, and continues to the present.
The specific experiences that qualify vary, but common patterns include: betting more money than you intended or could afford to lose; lying to family members or friends about your gambling; using gambling as a way to escape problems or relieve negative emotions; repeated unsuccessful efforts to cut back or stop; borrowing money or selling possessions to fund gambling; and jeopardizing relationships, employment, or educational opportunities because of gambling.
You do not need to have lost a specific amount of money. The harm is measured not just financially but through the impact on your life and wellbeing. Some people lost everything. Others caught the problem earlier but still suffered significant damage.
The disorder often develops quickly with app-based betting. Many people report going from casual use to compulsive gambling in a matter of months. The speed and accessibility of the apps compress the addiction timeline compared to traditional forms of gambling.
Certain groups appear to be at higher risk. Young men, particularly those aged 21 to 30, have the highest rates of sports betting participation and the highest rates of gambling disorder. People with prior substance use issues or mental health conditions are more vulnerable. Veterans and active-duty military personnel have shown elevated rates of problem gambling, and betting companies have actively marketed to this population through partnerships with military sports networks and sponsorships.
You do not need to have hit rock bottom. Many people with gambling disorder are still functioning in their daily lives while experiencing serious harm. You do not need to have drained your bank account or lost your home. If betting apps changed your relationship with gambling and caused harm that you could not control, that matters.
Where Things Stand
Litigation against sports betting companies is in its early stages but expanding rapidly. The first wave of lawsuits was filed in 2022, primarily in Massachusetts, New Jersey, and Pennsylvania—states with high rates of mobile betting adoption and established case law on consumer protection and addiction liability.
As of early 2024, more than 200 individual cases have been filed against DraftKings, FanDuel, and BetMGM. The lawsuits allege negligence, fraud, unfair business practices, and violations of consumer protection statutes. Plaintiffs are seeking compensation for financial losses, emotional distress, and the cost of treatment for gambling disorder.
In October 2023, a federal judge in New Jersey denied a motion to dismiss filed by DraftKings and FanDuel, allowing several cases to proceed to discovery. The ruling found that plaintiffs had sufficiently alleged that the companies knew their apps were designed in ways that created unreasonable risks of addiction and that they failed to warn users of those risks.
Discovery is now underway in multiple cases, and internal documents are beginning to emerge. Early findings support what public health researchers have long suspected: the companies conducted extensive research into user behavior, identified design features that maximized addictive engagement, and prioritized revenue over user welfare.
Class action lawsuits have been proposed but not yet certified. The challenge with class certification in gambling addiction cases is demonstrating that the injuries are sufficiently similar across all plaintiffs. Courts have been reluctant to certify addiction-related classes in the past, preferring individual proceedings where specific causation can be established. However, the strength of the evidence regarding app design and the companies knowledge may support class treatment in some jurisdictions.
Several state attorneys general have opened investigations into the business practices of sports betting companies. In March 2023, the Massachusetts Attorney General issued a civil investigative demand to DraftKings seeking documents related to responsible gambling measures, user data collection, and targeted marketing practices. Similar investigations are underway in Illinois and Connecticut.
No settlements have been reached in the sports betting litigation as of this writing. The companies are defending aggressively, arguing that users voluntarily chose to gamble and that any losses are the result of personal decisions, not corporate wrongdoing. This is the same argument tobacco companies made for decades before internal documents proved they had deliberately hidden health risks.
The timeline for resolution is uncertain. Complex product liability and consumer protection cases typically take several years to reach trial. However, the pace may accelerate if damaging internal documents continue to surface or if early trials result in significant verdicts for plaintiffs. Bellwether trials—cases selected to help both sides assess the strength of their positions—are expected to begin in late 2024 or early 2025.
Legislative efforts are also underway. Several states are considering bills that would impose stricter regulations on sports betting apps, including mandatory betting limits, enhanced age verification, restrictions on advertising, and funding for gambling addiction treatment programs. The industry is lobbying heavily against these measures, but public awareness of gambling-related harm is growing.
International developments may influence U.S. litigation. In the United Kingdom, a 2023 government report called for a comprehensive review of online gambling regulations after data showed sharp increases in gambling-related suicides and financial crises. Australia implemented strict advertising restrictions in 2022 following similar findings. These international actions provide a roadmap for reform and bolster arguments that the harms are not isolated incidents but predictable consequences of unregulated app-based betting.
What happened to you was not bad luck. It was not a genetic predisposition or a moral weakness. It was the result of deliberate choices made by corporations that studied the science of addiction and built products designed to exploit it. They knew the risks. They knew the harm. They built the apps anyway and marketed them as entertainment.
The documents exist. The research exists. The timeline of corporate knowledge is becoming clearer with each round of discovery. What you experienced—the loss of control, the mounting desperation, the bewildering speed with which gambling consumed your life—was engineered. It happened to you because it was designed to happen. And you are not alone.
