You thought you could control it. Maybe at first, it was just a few dollars on a Sunday game, something to make watching more exciting. Your friends were doing it. The ads were everywhere during the game, celebrities smiling, talking about how easy it was. Then you won a little, and that feeling was electric. Then you lost, and you knew you could win it back. Then the app was sending you notifications at midnight, offering you bonus bets, free money to keep playing. Then you were betting on sports you had never watched, games in countries you could not name, at three in the morning, because the app made it so easy, so fast, so seamless that you could place a bet in four seconds without ever feeling like you were spending real money.
Then you looked at your bank account. Then your credit cards were maxed. Then you were lying to your spouse about where the money went. Then you missed your mortgage payment. Then you realized you could not stop, even when you wanted to, even when you promised yourself this was the last time. You thought this was a personal failing. You thought you lacked willpower. You thought something was broken inside you that made you different from everyone else who could just bet casually and walk away.
What your doctor may have told you, if you finally sought help, is that you developed gambling disorder, a recognized addiction in the Diagnostic and Statistical Manual of Mental Disorders. What your doctor may not have told you is how the platform you were using was engineered, tested, and refined to create exactly the pattern of behavior you experienced. What you may not know is that there is a substantial body of research, some of it conducted or funded by the gambling industry itself, examining how specific design features make online sports betting uniquely addictive compared to traditional gambling.
What Happened
Gambling disorder is not about lacking self-control or being weak. It is a diagnosable condition characterized by persistent and recurrent problematic gambling behavior that leads to significant impairment or distress. People with gambling disorder experience an inability to control or stop gambling despite severe negative consequences. They think constantly about gambling, need to bet increasing amounts of money to achieve the same excitement, become restless or irritable when trying to cut down, chase losses by betting more to win back what they lost, lie to family members about the extent of their gambling, jeopardize relationships and employment, and rely on others to provide money to relieve desperate financial situations caused by gambling.
The financial devastation is often catastrophic. People drain savings accounts, max out credit cards, take out loans they cannot repay, and sometimes resort to illegal activities to fund continued gambling. The average debt for people seeking treatment for gambling disorder is reported in studies to range from tens of thousands to over one hundred thousand dollars. Relationships dissolve under the weight of broken trust and financial strain. Spouses leave. Families fracture. The emotional toll includes severe anxiety, depression, and a suicide rate among people with gambling disorder that research has found to be significantly higher than the general population.
What makes sports betting particularly devastating is the speed and accessibility. Unlike driving to a casino, online sports betting is available every moment of every day on the phone in your pocket. Bets can be placed in seconds. The friction between impulse and action has been engineered to near zero. The result is that people can lose thousands of dollars in minutes, in their bedroom, in their car, at their desk at work, without any of the social or physical barriers that once limited gambling behavior.
The Connection
Online sports betting platforms cause compulsive gambling behavior through specific design mechanisms that research has shown exploit psychological vulnerabilities and neurological reward pathways. These are not accidental features. They are the product of extensive user testing, behavioral analysis, and deliberate design choices.
A 2020 study published in the International Journal of Environmental Research and Public Health examined the structural characteristics of online gambling that contribute to harm. Researchers identified several key features: continuous play with minimal interruption, rapid bet-to-outcome intervals, the use of virtual currency or cashless betting that obscures the real value of money, immediate access via mobile devices, personalized inducements delivered through push notifications, and the integration of social media elements that normalize and encourage repeated engagement.
The speed of online sports betting is particularly significant. Research published in 2019 in the journal Addictive Behaviors found that faster gambling formats are associated with greater risk of harm. Traditional sports betting required placing a wager and waiting for the outcome of a game, creating natural pauses. Online platforms now offer in-play or live betting, allowing users to place dozens of bets during a single game on events like the outcome of the next play, the next point scored, or whether a specific player will achieve a certain statistic in the next minute. This transforms betting from an occasional activity into a continuous, high-intensity experience that research has linked to loss of control.
Push notifications are another mechanism. A 2021 study in the Journal of Behavioral Addictions examined how personalized gambling messages increase engagement and spending. Platforms send notifications offering bonus bets, free money, and odds boosts at times when user data suggests the individual is most likely to bet. These messages create a sense of urgency and special opportunity that research has found triggers impulsive betting, particularly among people already developing problematic patterns.
The use of virtual currency and account-based betting rather than physical cash has been studied extensively. A 2018 review published in Psychology of Addictive Behaviors found that digital representations of money reduce the psychological pain of losing and make it easier to spend more than intended. When you tap a screen rather than hand over cash, when you see account balances rather than empty pockets, the financial reality of losses is cognitively distant. Platforms exploit this by displaying betting amounts in ways that minimize the perception of loss and maximize ease of continued play.
Bonus bets and promotions are particularly insidious. These offers are framed as free money or risk-free bets, but research has shown they function to increase overall betting volume and normalize higher spending. A 2022 study in the International Gambling Studies journal found that promotional offers lead users to place bets they would not otherwise make and to perceive those bets as less risky because they were placed with house money, even though the user has typically deposited substantial funds to qualify for the promotion.
Neurologically, gambling activates the same reward pathways in the brain as addictive substances. Research using functional MRI imaging has shown that near-misses in gambling, where the outcome is close to a win, activate reward-related brain regions almost as much as actual wins, creating a powerful drive to continue. Online sports betting platforms present near-misses frequently, with bets that almost hit, parlays that miss by one leg, and odds that were close but not quite enough. Each near-miss is a neurological hook.
What The Lawsuits Allege They Knew
Lawsuits filed against DraftKings, FanDuel, and BetMGM allege that these companies were aware of the addictive potential of their platforms and made deliberate design and marketing choices that prioritized user engagement and revenue over consumer safety. The complaints cite internal documents, marketing strategies, and public statements that plaintiffs say demonstrate corporate knowledge of gambling addiction risks.
According to complaints filed in multiple jurisdictions, DraftKings and FanDuel both emerged from the daily fantasy sports industry, which faced regulatory scrutiny and lawsuits in 2015 and 2016 over whether the contests constituted illegal gambling. During that period, the lawsuits allege, both companies commissioned research and received reports about the risks of addictive engagement with their platforms. When sports betting became legal following the 2018 Supreme Court decision in Murphy v. NCAA, the complaints claim these companies transitioned into sports betting with full knowledge of addiction risks but chose to implement design features known to maximize engagement.
A lawsuit filed in 2023 alleges that DraftKings internal data analyzed user behavior to identify high-frequency bettors and targeted them with personalized promotions designed to increase betting volume. The complaint cites statements from former employees, disclosed in the litigation, who described internal discussions about user engagement metrics that prioritized maximizing lifetime value of customers, which the lawsuit claims meant encouraging frequent and high-volume betting even among users showing signs of problem gambling behavior.
Complaints against FanDuel allege that the company employed behavioral psychologists and user experience designers who specifically studied how to reduce friction in the betting process and increase the speed and frequency of bets. The lawsuits cite a 2021 investor presentation, disclosed in discovery, in which FanDuel reported that its mobile app was designed to allow users to place a bet in under five seconds and that reducing the time between bets was a key performance metric. The complaints allege that FanDuel knew from published research that rapid betting is associated with addiction but chose to engineer its platform for maximum speed.
Lawsuits against BetMGM allege that the company, a joint venture between MGM Resorts and Entain, had access to decades of casino industry research on gambling addiction. The complaints claim that MGM Resorts has long been aware of problem gambling issues in its physical casinos and has funded research on the topic, yet when it launched BetMGM as an online platform, the lawsuits allege the company implemented features such as in-play betting, push notifications, and bonus structures that research has linked to compulsive gambling.
The complaints across these cases allege that all three companies were aware of studies published in peer-reviewed journals between 2018 and 2022 demonstrating that online gambling, particularly mobile sports betting, is associated with higher rates of gambling disorder than traditional forms of gambling. A frequently cited study, published in 2019 in the journal Computers in Human Behavior, found that online gamblers were more likely to experience gambling problems than land-based gamblers, and that the convenience and accessibility of mobile gambling were significant risk factors. The lawsuits allege that despite this published evidence, DraftKings, FanDuel, and BetMGM continued to expand mobile betting features and aggressive marketing without adequate safeguards.
Plaintiffs in these cases also point to the marketing strategies employed by these companies. The lawsuits allege that between 2019 and 2023, DraftKings, FanDuel, and BetMGM spent billions of dollars on advertising that saturated sports broadcasts, social media, and online platforms. The complaints claim this marketing was designed to normalize sports betting, make it appear risk-free and fun, and deliberately target younger audiences and people without prior gambling experience. The lawsuits cite advertising campaigns featuring celebrities and sports personalities, partnerships with major sports leagues and teams, and promotions offering thousands of dollars in bonus bets to new users, all of which the complaints allege were intended to drive rapid user acquisition without corresponding efforts to screen for or prevent gambling addiction.
What The Lawsuits Say About Concealment
The lawsuits allege that DraftKings, FanDuel, and BetMGM concealed the risks of gambling addiction through a combination of inadequate disclosures, misleading marketing, and lobbying efforts that shaped the regulatory environment in ways favorable to the industry.
Complaints filed in multiple states allege that the companies provided minimal and ineffective responsible gambling messaging. The lawsuits claim that while the platforms include links to responsible gambling resources, these are typically buried in settings menus or presented in small text that users rarely see. The complaints allege that this creates a veneer of responsibility without meaningfully informing users of addiction risks. According to the lawsuits, internal testing data, if disclosed in discovery, would show that the companies knew the vast majority of users never accessed responsible gambling tools, yet they made no effort to make these tools more prominent because doing so would reduce betting volume.
Plaintiffs allege that the companies engaged in regulatory lobbying to shape state gambling laws in ways that minimized consumer protections. The lawsuits cite legislative efforts in states such as New York, New Jersey, Illinois, and Pennsylvania, where the complaints claim DraftKings, FanDuel, and BetMGM or their industry trade groups lobbied for regulations that allowed aggressive marketing, minimal restrictions on promotional offers, and limited funding for problem gambling treatment. The complaints allege that the companies presented themselves as responsible actors in public while privately working to prevent meaningful oversight.
Some lawsuits allege that the companies used nondisclosure agreements and settlement terms in disputes with users and former employees to prevent information about platform design and internal knowledge of addiction risks from becoming public. The complaints claim that by quietly resolving complaints and requiring confidentiality, the companies concealed patterns of harm that might otherwise have warned consumers and regulators.
The lawsuits also allege that the companies misrepresented the nature of sports betting in their marketing, portraying it as a skill-based activity where knowledgeable bettors could consistently win, rather than as a form of gambling with a house edge that ensures the platform profits over time. The complaints cite advertisements and promotional materials that emphasized winning, success, and easy money, without disclosing that the vast majority of bettors lose money and that the platforms are designed to ensure long-term profitability for the company, not the user.
Why Your Doctor May Not Have Told You
Gambling disorder is underdiagnosed and undertreated, and many healthcare providers receive little training on recognizing or addressing it. Unlike substance addictions, gambling disorder leaves no physical traces such as bloodwork abnormalities or visible signs, making it easy to miss unless a patient specifically raises the issue. Many people struggling with gambling problems feel shame and hide the behavior from their doctors, and physicians often do not think to screen for it during routine visits.
The lawsuits allege that DraftKings, FanDuel, and BetMGM have done little to educate the medical community or the public about the specific risks of online sports betting. The complaints claim that while the companies fund limited responsible gambling initiatives, these efforts are dwarfed by their marketing budgets and are not designed to reach healthcare providers or effectively warn potential users. According to the lawsuits, the companies benefit from public and medical ignorance about the addictive design of their platforms, as widespread awareness would likely reduce user acquisition and engagement.
There is also a broader societal normalization of sports betting that the lawsuits allege the companies deliberately cultivated. By partnering with major sports leagues, placing advertisements during family programming, and integrating betting content into sports coverage, the complaints claim these companies have made betting seem like a routine part of watching sports rather than a high-risk activity that can lead to serious addiction. This normalization, the lawsuits allege, makes it less likely that doctors, family members, or users themselves will recognize problematic betting behavior until significant harm has occurred.
Who Is Affected
If you used DraftKings, FanDuel, BetMGM, or similar sports betting platforms and developed symptoms of gambling disorder, you may have been harmed by the design and marketing practices these lawsuits challenge. What does that look like in practice?
You may have started betting casually, perhaps with a promotional offer of free bets or bonus money when you signed up. Over time, your betting increased in frequency and amount. You found yourself thinking about betting when you were not doing it, planning your next bets, researching games and odds not because you enjoyed it but because you felt compelled to. You began betting on sports or events you knew nothing about because the app made it available and easy.
You may have tried to stop or cut back and found that you could not. You felt restless, anxious, or irritable when you were not betting. You started chasing losses, betting more to try to recover money you had lost. You lied to family or friends about how much you were betting or how much money you had lost. You may have borrowed money, sold possessions, or used funds meant for bills or savings to continue betting.
Financial harm is a key indicator. If you accumulated significant debt, depleted savings, maxed out credit cards, or faced financial hardship such as missed payments, repossession, foreclosure, or bankruptcy as a result of betting, this is evidence of harm. Relationship damage also matters. If your betting led to conflict, separation, divorce, or estrangement from family, that is part of the impact.
The timeframe is also important. Most of the major expansion of online sports betting occurred after 2018, and particularly after 2019 and 2020 when DraftKings, FanDuel, and BetMGM rapidly scaled their operations as more states legalized sports betting. If your use of these platforms and the development of your gambling problems occurred during this period, your experience may be relevant to the litigation.
You do not need to have been formally diagnosed with gambling disorder by a medical professional to have been harmed, though a diagnosis can be helpful. What matters is the pattern of use, the inability to control betting despite negative consequences, and the financial and personal harm that resulted.
Where Things Stand
Litigation against DraftKings, FanDuel, and BetMGM over gambling addiction and platform design is still in relatively early stages, but cases have been filed in multiple states. These lawsuits generally allege claims such as negligence, failure to warn, unfair and deceptive business practices, and violations of state consumer protection laws. Plaintiffs argue that the companies had a duty to design reasonably safe products, to warn users of addiction risks, and to refrain from deceptive marketing practices that downplayed those risks.
As of now, there have been no major settlements or trial verdicts in these sports betting addiction cases, which means the legal landscape is still developing. However, the cases are proceeding through discovery, a phase in which plaintiffs can request internal documents, data, and testimony from the companies. This process may reveal additional evidence about what the companies knew, when they knew it, and what design and marketing decisions they made.
Some cases have been filed as potential class actions, seeking to represent large groups of affected users, while others are individual lawsuits. The legal theories vary by state, as gambling law and consumer protection law differ across jurisdictions. Some states have specific statutes regulating gambling advertising and responsible gambling measures, and violations of these statutes may form the basis of claims.
The litigation faces defenses from the companies, which have argued in court filings that they comply with state gambling regulations, that they provide responsible gambling tools, and that individual users bear responsibility for their own gambling decisions. These arguments will be tested as cases move forward. The outcome of early cases, particularly any that go to trial or produce significant discovery, will shape the trajectory of the broader litigation.
The timeline for resolution is uncertain. Complex litigation of this type can take years to work through the courts. However, as more people come forward, as more evidence emerges through discovery, and as public awareness of the issue grows, there may be pressure on the companies to settle or change their practices.
What This Means
What happened to you was not a personal failure. It was not a matter of insufficient willpower or a character flaw. The platform you used was engineered by teams of designers, psychologists, and data scientists to maximize engagement, which in the context of gambling means maximizing the frequency and volume of betting. Every feature, from the speed of bet placement to the timing of push notifications to the structure of bonus offers, was tested and refined to encourage continued use.
The research on online gambling addiction existed before these platforms scaled to millions of users. Studies documenting the risks of rapid betting, mobile accessibility, cashless wagering, and personalized inducements were published in peer-reviewed journals. The lawsuits allege that the companies knew or should have known these risks and chose growth and profit over safety. That is not an accident. According to the complaints, it was a business decision, reflected in design choices, marketing spending, and lobbying efforts.
You were not gambling in a vacuum. You were using a product designed to be addictive, marketed to seem safe and fun, and operated by companies that the lawsuits allege prioritized revenue over the well-being of their users. What you experienced—the loss of control, the financial devastation, the damage to your relationships and your sense of self—was a foreseeable consequence of that design. The litigation is an effort to hold these companies accountable, to bring to light what they knew and when, and to seek justice for the people whose lives were upended. You are not alone in this, and what happened to you matters.
