You thought you had control. That is what everyone thinks at first. You downloaded the app because you liked sports, because the commercials made it look fun, because everyone at work was doing it. Maybe you won a little at the beginning. Maybe you felt smarter about the games, more connected to the outcomes. Then something shifted. You started checking scores not because you cared about the teams but because you had money on the third quarter. You started betting on sports you did not even follow. You found yourself opening the app at two in the morning, chasing losses, telling yourself this next one would get you even. When you finally looked at your bank account, when your partner asked where the money went, when you realized you had borrowed from people you loved to place bets you could not afford, the shame was suffocating. You wondered what was wrong with you. Why you could not stop something that had started as entertainment.
Your doctor may have used the term gambling disorder. They may have explained that your brain had been changed by repeated exposure to variable reward patterns, that the behavior had become compulsive, that this was not a failure of willpower. You may have felt relief at having a name for it, and then immediate doubt. You are not someone who loses control. You do not have an addictive personality. You were just trying to have fun, trying to make watching games more interesting, trying to win back what you lost. How did something that was legal, that was advertised during every commercial break, that celebrities promoted, that was supposed to be entertainment, turn into something that destroyed your finances, your relationships, and your sense of who you are?
What you may not know is that litigation filed against the largest sports betting platforms alleges that the features that pulled you in, the notifications that brought you back, the free bets that kept you playing, and the reward systems that made losing feel like almost winning were not accidents. According to court filings, these companies studied how to maximize engagement, how to encourage continuous play, and how to turn casual bettors into high-frequency users, even as data accumulated about the addiction risks of app-based gambling. The lawsuits allege that what felt like your failure was actually the outcome of deliberate design choices, tested and refined to keep you betting.
What Happened
Gambling disorder is a recognized psychiatric condition in which a person loses the ability to control their gambling behavior despite serious negative consequences. It is not about loving sports too much or being bad with money. It is a pattern of brain change that occurs when someone is repeatedly exposed to the neurochemical reward cycle that gambling creates. People with gambling disorder feel an overwhelming urge to gamble, even when they know it is harming them. They chase losses, meaning they keep betting to try to win back money they have already lost. They lie to family members about how much they are betting. They borrow money, drain savings, max out credit cards, and in some cases lose their homes.
The emotional experience is one of mounting desperation and shame. You feel anxious when you are not betting and relieved when you place a bet, but that relief lasts only seconds. You feel a high when you win, but it is never enough to stop. You feel crushing guilt when you lose, but that guilt drives you to bet again, because winning feels like the only way to undo the damage. The disorder often comes with depression, anxiety, insomnia, and in severe cases, suicidal thoughts. Relationships fall apart. Jobs are lost. People describe feeling like they are watching themselves make destructive decisions but cannot stop.
What makes app-based sports betting particularly dangerous, according to experts who have testified in litigation and published research on gambling behavior, is the speed and accessibility. You can place a bet in seconds, from anywhere, at any time. There is no drive to a casino, no chips to buy, no physical moment of decision that creates a pause. The apps allow in-play betting, meaning you can bet on every play, every quarter, every moment of a game. The feedback loop between impulse and action is nearly instantaneous. The variable reward schedule, where wins are unpredictable but frequent enough to keep you hoping, is one of the most powerful behavioral conditioning tools known to psychology. It is the same mechanism that makes slot machines addictive. The lawsuits allege that sports betting companies built their platforms around these principles.
The Connection
Sports betting apps are designed to deliver a neurochemical experience. When you place a bet, your brain releases dopamine in anticipation of a possible reward. Dopamine is the neurotransmitter associated with motivation, pleasure, and learning. It does not just spike when you win. It spikes when you are waiting to find out if you won. That state of uncertainty is what drives compulsive behavior. The more unpredictable the reward, the more dopamine is released, and the more your brain learns to repeat the action.
A study published in the journal Neuroscience & Biobehavioral Reviews in 2020 examined the neural mechanisms of gambling disorder and found that repeated gambling exposure leads to changes in the brain regions responsible for impulse control and decision-making. The prefrontal cortex, which normally helps you weigh consequences and delay gratification, becomes less active. The reward circuitry becomes hypersensitive. This is not a metaphor. These are measurable changes in brain function. The study noted that the speed of betting and the use of digital interfaces that remove friction from the process can accelerate these changes.
Another study published in Addictive Behaviors in 2021 specifically looked at mobile gambling apps and found that features such as push notifications, in-play betting, and rapid bet settlement were associated with higher rates of problem gambling. The researchers noted that these design features are not neutral. They are behavioral nudges that encourage continued play. The study found that people who used mobile betting apps were significantly more likely to develop gambling problems than those who bet in person, even when controlling for frequency of gambling.
The lawsuits allege that the major sports betting platforms knew this. Court filings cite internal research, user behavior data, and communications between executives that allegedly show the companies studied how to increase time on platform, how to convert casual users into daily users, and how to encourage higher-frequency betting. The complaints allege that the companies used behavioral psychology techniques, including variable reward schedules, near-miss outcomes that feel like almost winning, and personalized notifications timed to moments of high engagement, to maximize the addictive potential of their platforms.
What The Lawsuits Allege They Knew
The lawsuits filed against DraftKings, FanDuel, and BetMGM allege that these companies were aware of the addiction risks associated with their platform design choices and chose profit over safety. These are allegations made in court filings, not findings of fact, but they are based on documents, testimony, and research that the plaintiffs say demonstrate a pattern of knowledge and inaction.
According to complaints filed in multiple jurisdictions beginning in 2023, DraftKings and FanDuel both conducted internal user research as early as 2019 and 2020 that tracked metrics related to problem gambling behaviors. The lawsuits allege that these companies monitored data points such as frequency of login, speed of repeat betting, and patterns of chasing losses. Plaintiffs claim that the companies had access to behavioral data showing that certain users were exhibiting signs of compulsive gambling, including betting beyond their stated deposit limits when offered promotional credits and returning to the app within minutes of a loss.
One complaint references a 2021 presentation allegedly circulated among product managers at DraftKings that discussed user engagement strategies and included analysis of how push notifications affected betting frequency. The lawsuit claims that the presentation showed that users who received notifications about live games or expiring free bets were significantly more likely to place bets within the next hour, and that the company used this data to optimize notification timing. The plaintiffs allege that the company did not disclose these engagement strategies to users or warn them that the platform was designed to encourage repeated use.
The lawsuits also allege that FanDuel conducted A/B testing on features such as the placement of cash-out buttons, the display of near-miss outcomes, and the frequency of promotional offers. According to the complaints, internal emails from 2020 allegedly discussed which design variations led to higher betting volume and longer session times. The plaintiffs claim that these tests were conducted without informed consent from users and without consideration of the addiction risks associated with maximizing engagement.
BetMGM, a joint venture between MGM Resorts and Entain, is alleged in court filings to have relied on research and behavioral models developed by its parent companies, both of which have decades of experience in casino gambling. The lawsuits claim that BetMGM had access to studies conducted by the gambling industry showing that speed of play and ease of access are primary risk factors for gambling disorder. One complaint cites a 2018 study commissioned by Entain, then known as GVC Holdings, that examined responsible gambling measures and reportedly found that the most effective interventions were those that created friction in the betting process, such as mandatory pauses and deposit limits. The lawsuit alleges that despite this knowledge, BetMGM designed its app to minimize friction and maximize speed, incorporating features such as one-click betting and instant deposit options.
Congressional testimony from a 2022 hearing on sports betting regulation included statements from researchers and former employees of sports betting companies who described a culture focused on user acquisition and engagement metrics, with limited attention to responsible gambling measures. According to the lawsuits, one former data analyst testified that user behavior data showing patterns consistent with problem gambling were flagged internally but did not result in changes to platform features or outreach to affected users. The complaints allege that this testimony supports the claim that the companies prioritized growth over safety.
The lawsuits also allege that the companies were aware of public health research documenting the risks of mobile gambling. A widely cited study published in the Journal of Behavioral Addictions in 2019 found that the legalization of online sports betting in jurisdictions outside the United States was associated with significant increases in gambling disorder rates, particularly among young men. The study noted that the convenience and accessibility of mobile betting, combined with aggressive marketing, created a public health risk. The complaints allege that DraftKings, FanDuel, and BetMGM were aware of this research as they expanded operations following the 2018 Supreme Court decision that allowed states to legalize sports betting, but did not implement adequate safeguards.
What The Lawsuits Say About Concealment
The complaints allege that the sports betting companies not only failed to warn users about addiction risks but actively concealed the manipulative nature of their platform design. These allegations are central to the litigation and remain contested by the defendants.
According to the lawsuits, the companies marketed their apps as entertainment and skill-based activities, emphasizing the social and recreational aspects of sports betting while downplaying the risks. Advertising campaigns featured celebrities, athletes, and influencers who presented betting as fun, easy, and a normal part of watching sports. The complaints allege that this marketing strategy was designed to normalize gambling and reduce the perception of risk, particularly among younger users who had not previously gambled.
The lawsuits also allege that the companies used promotional offers, including risk-free bets and deposit bonuses, to encourage new users to begin betting and existing users to increase their activity. These promotions are alleged to have been particularly effective at driving compulsive behavior because they created a perception of free money and reduced the psychological friction associated with risking real funds. The complaints claim that users who accepted promotional offers were more likely to develop patterns of problem gambling because the promotions encouraged higher-frequency betting during the critical early period when behavioral patterns were being established.
One allegation that appears in multiple complaints is that the companies used data-driven personalization to target users who were most likely to become high-frequency bettors. The lawsuits claim that algorithms analyzed user behavior and tailored notifications, offers, and in-app messaging to encourage continued play. Plaintiffs allege that users who exhibited early signs of compulsive behavior, such as rapid repeat betting or chasing losses, were sent personalized offers designed to bring them back to the app, rather than being flagged for responsible gambling interventions.
The complaints also allege that the companies lobbied against regulatory measures that would have required more robust responsible gambling features. According to court filings, industry groups funded by DraftKings, FanDuel, and BetMGM opposed state legislation that would have mandated cooling-off periods, mandatory deposit limits, and real-time spending alerts. The lawsuits claim that this lobbying effort was intended to preserve the design features that drove engagement and revenue, even as evidence of harm accumulated.
Another allegation involves the handling of user complaints and self-exclusion requests. The lawsuits claim that users who attempted to self-exclude from one platform were still able to receive marketing communications from affiliated brands and that the self-exclusion process was deliberately cumbersome, requiring multiple steps and offering limited support for users trying to stop gambling. Some complaints allege that users who contacted customer service to report gambling problems were offered promotional credits or bonuses instead of being directed to responsible gambling resources.
Why Your Doctor May Not Have Told You
Gambling disorder is underdiagnosed and undertreated, in part because many healthcare providers do not routinely screen for it. It is not included in standard wellness visits. It does not show up in blood work. Unless you volunteer that you have a problem with gambling, your doctor may never ask. And many people do not recognize their own behavior as disordered until the consequences are severe.
The lawsuits allege that the sports betting companies contributed to this gap in awareness by framing their products as entertainment rather than gambling. Because the apps are marketed as skill-based and social, users may not think of themselves as gamblers in the traditional sense. They may not realize that the behavior they are engaging in carries the same addiction risks as casino gambling. The complaints claim that this framing was intentional and that the companies avoided using language associated with risk or addiction in their marketing and user interfaces.
Public health campaigns about gambling addiction have historically focused on casinos and lottery tickets. The rapid expansion of mobile sports betting, which only became legal in most states after 2018, has outpaced public awareness efforts. Many people, including healthcare providers, are not yet aware that app-based sports betting is a high-risk activity for gambling disorder. The lawsuits allege that the companies did little to educate users or the public about these risks, even as their internal data showed rising rates of problem gambling among users.
There is also a broader issue of how information about behavioral addiction reaches the medical community. Unlike pharmaceutical products, which are subject to FDA oversight and required to provide prescribing information and risk warnings, gambling platforms are regulated at the state level with wide variation in requirements. There is no standardized system for reporting adverse outcomes such as gambling disorder, and no mechanism for alerting healthcare providers when a product is associated with harm. The lawsuits allege that the companies exploited this regulatory gap by operating with minimal disclosure requirements and no obligation to fund independent research on the health effects of their platforms.
Who Is Affected
If you downloaded a sports betting app such as DraftKings, FanDuel, or BetMGM and subsequently developed gambling disorder, you may be part of the population affected by the conduct alleged in these lawsuits. This typically includes people who began using sports betting apps after 2018, when mobile sports betting became legal in many states, and who experienced a pattern of increasing gambling behavior that led to financial harm, relationship damage, or mental health consequences.
The profile of someone affected often looks like this: You were not someone who gambled regularly before. Maybe you went to a casino once or twice, bought a lottery ticket, played poker with friends. But it was not a part of your life. Then sports betting became legal and accessible. You saw the ads. You got a sign-up bonus. You started small. At first it was fun. You won some, lost some. But over weeks or months, you found yourself betting more frequently. You started betting on games you did not care about, just to have action. You chased losses. You hid your betting from people close to you. You borrowed money or used funds that were meant for bills or savings. You tried to stop and could not.
You may have experienced financial devastation. Drained bank accounts, maxed-out credit cards, loans you cannot repay. You may have lost relationships. Partners who left because of the lying or the money. Family members who no longer trust you. You may have lost your job because you were betting during work hours or because the stress and distraction made it impossible to function. You may have thought about suicide. You may have attempted it. The lawsuits allege that these outcomes were foreseeable and preventable, and that the companies chose design features that maximized profit at the expense of user safety.
The condition does not discriminate by income, education, or background. It affects people who thought they were too smart or too disciplined to develop a problem. It affects people who have no other history of addiction. The common thread is exposure to a product designed to be habit-forming, during a period of rapid expansion and aggressive marketing, with minimal regulatory oversight.
Where Things Stand
Litigation against DraftKings, FanDuel, and BetMGM is in its early stages, with complaints filed in multiple states beginning in 2023. The cases are being closely watched as a test of whether gambling companies can be held liable for harms associated with platform design and behavioral manipulation. As of early 2024, no settlements or verdicts have been reached, but the volume of cases is growing as more people come forward with similar experiences.
The legal theories underlying the cases include product liability, negligence, fraud, and violations of state consumer protection laws. Plaintiffs argue that the apps are defectively designed products that cause foreseeable harm, that the companies failed to warn users of known risks, and that they engaged in deceptive marketing by presenting gambling as entertainment without disclosing the addiction potential. Some complaints also allege unjust enrichment, claiming that the companies profited from users whose behavior met clinical criteria for gambling disorder.
The defendants have filed motions to dismiss in several jurisdictions, arguing that gambling is a lawful activity, that users chose to participate, and that the companies are not responsible for individual outcomes. They have also argued that they provide responsible gambling tools such as deposit limits and self-exclusion options, and that users who develop problems failed to use those tools. The courts have not yet ruled on the core liability questions, and the litigation is expected to involve extensive discovery regarding internal company research, design decisions, and knowledge of harm.
There are also regulatory developments that may affect the legal landscape. Several states have introduced legislation to strengthen responsible gambling requirements for sports betting platforms, including mandatory spending limits, cooling-off periods, and restrictions on promotional offers. Some lawmakers have called for federal oversight of online gambling. The outcomes of these cases may influence whether and how such regulations are adopted.
For individuals considering whether to participate in the litigation, the process typically begins with a consultation with an attorney who specializes in product liability or mass tort cases. The attorney will review your history of app usage, your financial and medical records related to gambling disorder, and the timeline of your experience. Because these cases are still developing, there is no established settlement structure or compensation framework. The goal of the litigation is to hold the companies accountable for the harms alleged in the complaints and to obtain relief for those who were injured.
What This Means For You
If you developed gambling disorder after using a sports betting app, what happened to you was not a personal failing. It was not because you lack discipline or because you are weak. The lawsuits allege that you were using a product designed to exploit the way your brain responds to uncertainty and reward, a product built by companies that had data showing the risks and chose to prioritize engagement and revenue over safety. The shame you feel, the belief that you should have been able to stop, the confusion about how something legal and heavily advertised could destroy your life—those feelings are common among people who have been harmed by products designed to be addictive.
You are not alone in this. Thousands of people have had the same experience. They downloaded an app, thought they were making a choice, and found themselves trapped in a cycle of compulsive behavior that they could not control. The litigation alleges that this was not an accident. It was the result of deliberate design decisions, tested and refined, built on decades of research into how to keep people gambling. What felt like your failure was actually the outcome of a system built to keep you engaged, no matter the cost. You deserve to know that, and you deserve to have your experience acknowledged and addressed.
