You downloaded an app. You placed a few bets during football season, maybe with a friend, maybe because you saw the ads everywhere. It felt like entertainment, like fantasy sports with real money on the line. Then something shifted. You found yourself betting on games you did not care about, sports you had never watched, checking scores at work, in bed, at dinner with your family. You told yourself you would stop after one more win, one more chance to break even. The wins came sometimes, enough to keep you going, but the losses piled up faster than you could track. Bank accounts emptied. Credit cards maxed out. Relationships fractured. And through it all, a voice in your head saying: This is your fault. You should have had more control.
When you finally sat across from a counselor or a doctor and heard the words gambling disorder, it might have felt like a label for a personal failure. Something weak in your character. A lack of willpower. But what your doctor may not have told you, because they may not have known themselves, is that the platform you were using was engineered with precision to keep you betting. The colors, the sounds, the push notifications, the in-game live betting that turned every possession into a new wager. These were not accidents. They were design choices, built on research about how human brains respond to variable rewards, how dopamine pathways light up with uncertainty, how losses disguised as wins keep people playing.
What you experienced was not a moral failing. It was a documented outcome of a business model. And now, lawsuits filed across the country allege that the companies behind the biggest sports betting apps in America—DraftKings, FanDuel, and BetMGM—knew their platforms carried serious risks of addiction, designed them to maximize engagement regardless of harm, and failed to warn users or implement meaningful safeguards. This is what those court filings say happened, and what the public record shows about how sports betting addiction became an American crisis.
What Happened
Gambling disorder is not about liking sports too much or being bad with money. It is a recognized psychiatric condition, classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) under behavioral addictions. It changes the way your brain processes reward and risk. People with gambling disorder experience intense cravings to bet, an inability to stop even when they want to, and a progressive need to wager larger amounts to achieve the same feeling. They chase losses, betting more to try to win back what they have lost, creating a cycle that accelerates financial devastation.
The emotional toll is severe. Anxiety and depression are common, often worsening as debts mount. Relationships collapse under the weight of broken trust and financial secrecy. People withdraw from friends and family, lying about where money went, why they are always on their phones, why they seem distant and irritable. Work performance deteriorates. Some people lose their jobs. Others lose their homes. Bankruptcy filings among people with gambling disorder have become increasingly common since mobile sports betting expanded across the United States.
Physical symptoms emerge too. Sleep disruption is pervasive—people stay up late betting on West Coast games, international soccer, Australian tennis, anything with action. The constant stress produces headaches, digestive problems, elevated blood pressure. Some people describe a physical restlessness, an agitation that only subsides when they place a bet, which provides temporary relief before the cycle begins again. Suicidal ideation is tragically common. The National Council on Problem Gambling reports that individuals with gambling disorder have the highest suicide rate of any behavioral addiction.
For many people, the speed of the decline is shocking. Unlike casino gambling, which required a trip to a physical location, mobile sports betting is available every second of every day, in your pocket, on your couch, in your car, at your desk. There is no natural break, no moment when the casino closes and you have to go home. The apps are designed to eliminate friction, to make placing a bet as effortless as liking a post on social media. Within months, people who had never had a gambling problem in their lives found themselves in financial ruin, unable to explain how it happened so fast.
The Connection
Mobile sports betting platforms cause gambling disorder through a combination of psychological manipulation, design features that exploit known addiction pathways, and the removal of traditional barriers that once limited gambling behavior. The mechanism is well-documented in behavioral science literature, and the specific features these apps employ are not accidental—they are engineered based on decades of research into how to maximize user engagement.
The core driver is variable ratio reinforcement, a concept studied extensively since B.F. Skinner's work in the 1950s. When rewards come unpredictably, the brain releases dopamine not just when you win, but in anticipation of a possible win. This creates a powerful compulsion to keep engaging. Slot machines have used this principle for decades. Sports betting apps apply the same mechanism but with dozens of additional layers of psychological manipulation.
Live in-game betting, also called in-play or micro-betting, is particularly addictive. Instead of placing one bet before a game starts and waiting for the outcome, users can bet on every play, every possession, every at-bat. A 2022 study published in the Journal of Behavioral Addictions found that in-game betting was associated with significantly higher rates of problem gambling compared to traditional pre-game betting. The constant action eliminates the natural pauses that might allow someone to reflect, step back, or stop. Each bet is resolved quickly, providing either a hit of dopamine or a loss that triggers the urge to chase.
The apps use push notifications to bring users back into the platform. Notifications about games starting, about promotional offers, about bets you could place right now. A 2023 study from the University of Sydney found that push notifications from gambling apps were a significant predictor of gambling frequency and problem gambling severity. The notifications create a sense of urgency and FOMO—fear of missing out—that overrides rational decision-making.
Bonus structures and promotional offers are designed to obscure losses and create the illusion of winning. Free bets, deposit matches, and odds boosts are marketed as gifts, but they come with rollover requirements and conditions that make it nearly impossible to withdraw winnings without placing many additional bets. These promotions are most heavily targeted at new users and at people who have reduced their betting activity, pulling them back in precisely when they might be trying to stop.
The apps also employ losses disguised as wins, a concept studied extensively in slot machine research. When you place a parlay bet with five legs and four of them hit, the app celebrates the near-miss with sounds and animations, even though you lost money. This triggers the same dopamine response as a win, encouraging continued play. A 2021 study in the International Gambling Studies journal found that these near-miss experiences were strongly associated with continued gambling and increased bet size.
Accessibility is itself a mechanism of harm. Traditional gambling required planning, transportation, and social exposure—you had to go somewhere, be seen, interact with other people. Mobile sports betting removes all of those friction points. You can bet in private, instantly, in any emotional state, at any time of day or night. Research published in Addictive Behaviors in 2023 found that the convenience and privacy of mobile gambling were independent risk factors for developing gambling disorder, separate from the design features of the apps themselves.
The speed of play is unprecedented. You can place a bet, see the result, and place another bet in seconds. This rapid cycle does not allow time for the cognitive processes that might lead someone to stop—to calculate losses, to reflect on consequences, to remember why they wanted to quit. The faster the cycle, the more addictive the behavior. This is a principle casinos have understood for generations, and mobile apps have perfected it.
What The Lawsuits Allege They Knew
The lawsuits filed against DraftKings, FanDuel, and BetMGM allege that these companies were aware of the addiction risks their platforms created and had access to research and data showing the harm their design features caused. The complaints cite internal company data, public statements, and published research that was available to these companies as they built and marketed their products.
According to court filings, DraftKings and FanDuel both emerged from the daily fantasy sports industry, which faced intense scrutiny in 2015 and 2016 over whether it constituted illegal gambling. During that period, both companies commissioned research and made public statements about responsible gaming and the differences between skill and chance. The lawsuits allege that through this process, both companies became intimately familiar with gambling addiction research and the regulatory frameworks designed to protect consumers from harm.
A complaint filed in 2024 alleges that DraftKings had access to data showing that a small percentage of users generated a disproportionate share of revenue—a pattern consistent with problem gambling behavior. The lawsuit cites research published in the Journal of Gambling Studies in 2019 showing that in online gambling, approximately 10 to 15 percent of users account for 70 to 80 percent of revenue, and that this heavy-user segment exhibits significantly higher rates of gambling disorder. The complaint alleges that DraftKings had similar internal data but did not disclose it or implement design changes to protect high-risk users.
The lawsuits allege that all three companies were aware of research on in-game betting and addiction risk before they made live betting a central feature of their platforms. A widely cited study from the UK Gambling Commission in 2018 found that in-play betting was associated with higher rates of problem gambling, particularly among younger users. The complaints allege that despite this knowledge, DraftKings, FanDuel, and BetMGM expanded their live betting offerings and promoted them aggressively, because these features generated higher engagement and revenue.
According to court filings, BetMGM, which is a joint venture between MGM Resorts and Entain, had access to decades of casino industry research on addiction and responsible gaming. The lawsuits allege that MGM Resorts, as a brick-and-mortar casino operator, had implemented various responsible gaming measures in its physical locations—such as self-exclusion programs, visible clocks, and limits on ATM access—but that BetMGM did not implement comparable protections in its mobile app, despite knowing the risks were similar or greater.
The complaints point to statements made by company executives and marketing materials that allegedly contradict the companies' internal knowledge. The lawsuits cite advertising campaigns that portrayed sports betting as entertainment, as a social activity among friends, and as a harmless enhancement to watching sports. According to the court filings, these representations were made at the same time the companies had data showing significant rates of problem gambling among their users and were implementing features specifically designed to maximize betting frequency.
A 2023 complaint references testimony given to state legislatures by representatives of DraftKings and FanDuel during the legislative debates over legalizing mobile sports betting. According to the lawsuit, company representatives assured lawmakers that robust responsible gaming tools would be built into the platforms and that the companies would prioritize player safety. The complaint alleges that the tools actually implemented were insufficient, difficult to find, and designed in ways that discouraged their use.
The lawsuits also allege that the companies were aware of research on push notifications and their role in triggering compulsive behavior. A study published in Computers in Human Behavior in 2020 examined how notifications from gambling apps affected user behavior and found that they significantly increased betting frequency and were associated with loss of control. The complaints allege that despite this research being publicly available, the companies increased the frequency and urgency of their push notifications because internal data showed notifications drove user engagement and revenue.
What The Lawsuits Say About Concealment
The court filings allege that the sports betting companies engaged in multiple forms of concealment and misrepresentation regarding the risks of their products. These allegations have not been proven in court, but they represent the claims that plaintiffs are making in the litigation.
The lawsuits allege that the companies marketed their platforms as entertainment and skill-based competition rather than as gambling products that carried serious addiction risks. According to the complaints, this framing was strategic, designed to appeal to sports fans who might not consider themselves gamblers and who would not think of themselves as vulnerable to gambling disorder. The court filings claim this was misleading because the companies had data showing their products functioned like other forms of gambling and produced similar rates of addiction.
According to the complaints, the companies placed responsible gaming tools in obscure locations within their apps, requiring users to navigate through multiple menus to access deposit limits, time limits, or self-exclusion options. The lawsuits allege this design choice was intentional, meant to give the appearance of offering safeguards while making them difficult enough to find that few users would actually implement them. The complaints contrast this with the prominent placement of promotional offers and betting options, which the lawsuits say reveals the companies' true priorities.
The court filings allege that when users did attempt to self-exclude or set limits, the companies sometimes sent them promotional offers encouraging them to return or to increase their limits. The lawsuits cite specific examples of users who reported setting deposit limits and then receiving emails or notifications about bonus offers or opportunities they were missing. According to the complaints, this undermined the effectiveness of the responsible gaming tools and demonstrated that the companies prioritized revenue over user safety.
The lawsuits allege that the companies lobbied state legislatures to minimize regulatory requirements around consumer protection. According to the complaints, the companies advocated for frameworks that would allow them to operate with fewer restrictions than brick-and-mortar casinos, arguing that mobile betting was fundamentally different and less risky. The court filings allege this lobbying was not based on good-faith belief but on business interests, and that the companies had internal information contradicting their public positions.
Some complaints allege that the companies failed to adequately screen for underage users and problem gamblers during account signup. The lawsuits claim that the verification processes were minimal, designed to reduce friction in the signup process rather than to ensure compliance with responsible gaming principles. According to the court filings, the companies knew that easier signup processes led to more users and more revenue, and they prioritized that outcome over safety measures that might have prevented vulnerable individuals from accessing the platforms.
The complaints also allege that the companies did not disclose the mathematical realities of sports betting—specifically, that the odds are structured so that over time, the vast majority of users will lose money. The lawsuits claim that the companies allowed users to develop false beliefs about their chances of long-term success, and that marketing materials emphasized stories of big winners while obscuring the statistical certainty of losses for most users. According to the court filings, this constituted a form of concealment because the companies had the data showing actual user outcomes but chose not to share it.
Why Your Doctor May Not Have Told You
If you were treated for anxiety, depression, insomnia, or relationship problems without anyone asking about gambling, you are not alone. Medical professionals are often unaware of the prevalence and severity of gambling disorder, particularly as it relates to mobile sports betting apps. There are several reasons why your doctor may not have connected your symptoms to your betting behavior.
First, gambling disorder is relatively underrecognized in general medical practice. Unlike substance use disorders, which have clear physical markers and are routinely screened for in many healthcare settings, gambling disorder is a behavioral addiction that can be invisible unless a provider specifically asks about it. Many medical schools provide minimal training on behavioral addictions, and continuing education on the topic is limited. Unless a doctor has a particular interest in addiction medicine, they may not think to ask about gambling when a patient presents with depression, anxiety, or financial stress.
Second, the rapid expansion of mobile sports betting is a recent phenomenon. While sports betting was legalized by the Supreme Court in 2018, the widespread availability of mobile betting apps is even more recent in most states. The medical literature on mobile sports betting addiction is still emerging, and clinical guidelines have not caught up with the reality that millions of Americans now carry highly addictive gambling platforms in their pockets. Many physicians simply do not realize how prevalent the problem has become.
Third, there is a social stigma around gambling problems that makes patients reluctant to disclose them. Unlike drinking or drug use, which patients may mention or which may show up in lab work, gambling behavior is entirely private. Many people with gambling disorder feel deep shame and are actively hiding their behavior from family and friends, let alone from medical providers. Unless a doctor asks directly and creates a safe space for disclosure, patients are unlikely to bring it up themselves.
The lawsuits allege that the sports betting companies contributed to this gap in medical awareness by framing their products as entertainment rather than gambling, which further obscured the health risks. According to the court filings, the companies did not undertake public health campaigns to educate medical providers about gambling disorder, did not fund research into treatment protocols, and did not support the kind of medical education initiatives that pharmaceutical companies are often required to conduct when they market products with serious side effects.
The complaints also allege that the companies did not provide clear warnings within their apps that would prompt users to seek medical attention if they developed symptoms of gambling disorder. According to the lawsuits, the responsible gaming sections of the apps typically linked to external resources like the National Council on Problem Gambling hotline, but did not include information that would help users recognize the signs of addiction in themselves or understand that what they were experiencing was a medical condition rather than a personal failure.
In general, information about emerging health risks reaches physicians through a combination of medical literature, continuing education, public health campaigns, and product warnings. When a new drug causes an unexpected side effect, there are regulatory mechanisms to ensure that information reaches prescribing doctors. No comparable system exists for gambling products. The lawsuits allege that in the absence of such a system, the companies had a responsibility to proactively educate both users and the medical community about the risks, and that they failed to do so.
Who Is Affected
If you used DraftKings, FanDuel, or BetMGM and developed gambling problems that caused financial, emotional, or relationship harm, you may be among those affected. The typical experience looks like this: You downloaded a sports betting app sometime after 2018, when mobile sports betting became legal in your state. You may have received a promotional offer—a deposit match, free bets, or enhanced odds for new users. You started betting on sports you watched, then on sports you did not watch. The betting became more frequent and the amounts grew larger.
You found yourself thinking about betting constantly, checking the app throughout the day, planning your schedule around games and betting opportunities. You chased losses, convincing yourself that the next bet would help you break even. You may have borrowed money, taken cash advances on credit cards, or hidden financial problems from family members. You continued betting even as you recognized the harm it was causing, feeling unable to stop despite wanting to.
The condition often progresses rapidly with mobile betting. Many people who never had gambling problems before, who may not have even considered themselves gamblers, found themselves meeting diagnostic criteria for gambling disorder within months of downloading an app. If you experienced withdrawal symptoms when you tried to stop—anxiety, restlessness, irritability—that is part of the recognized pattern of addiction.
You might have tried to use the responsible gaming tools within the app but found them ineffective. You might have set deposit limits and then overridden them, or self-excluded temporarily and then opened a new account with a different platform. The compulsion to bet can override rational intentions, and that is not a personal failure—it is the nature of the disorder.
People affected come from all demographics. The lawsuits represent users across age groups, income levels, and backgrounds. What they have in common is that they used mobile sports betting platforms that were designed to maximize engagement, and they developed gambling disorder as a result. Some people lost thousands of dollars. Others lost hundreds of thousands. Some lost their marriages, their jobs, their homes. The severity varies, but the core experience is the same: a loss of control over betting behavior that caused serious harm.
Where Things Stand
Litigation against DraftKings, FanDuel, and BetMGM is in its early stages. Individual lawsuits have been filed in multiple states, and attorneys are evaluating whether the cases will be consolidated into multidistrict litigation, which would centralize pretrial proceedings in a single federal court. As of early 2025, no settlements or trial verdicts have been reached, but the legal process is moving forward.
The claims being pursued include allegations of deceptive marketing, failure to warn, negligent design, and violations of state consumer protection laws. Some complaints also allege violations of state gambling regulations, arguing that the companies failed to implement required responsible gaming measures. The legal theories vary by jurisdiction depending on state law, but the core allegations about corporate knowledge and design choices are consistent across cases.
Plaintiffs are seeking compensation for financial losses, medical expenses for treatment of gambling disorder and related mental health conditions, and damages for emotional distress and relationship harm. Some complaints also seek punitive damages, arguing that the companies acted with reckless disregard for user safety in pursuit of profit.
The discovery process will be critical in these cases. Plaintiffs are seeking internal company documents, including research on user behavior, data on problem gambling rates among users, communications about design decisions, and marketing strategy materials. The lawsuits allege that these documents will show the companies knew their products were causing harm and chose not to act. The companies are expected to vigorously defend the cases, likely arguing that users are responsible for their own betting decisions and that the companies provided adequate warnings and tools.
Regulatory scrutiny is also increasing. Several state legislatures have considered or passed new restrictions on sports betting advertising, particularly ads targeting young adults. Some states have proposed mandatory cooling-off periods, more prominent placement of responsible gaming tools, or restrictions on in-game betting. The lawsuits may influence these regulatory discussions by bringing internal company practices into the public record.
For individuals considering legal action, the timeline varies by state. Statutes of limitations differ, and in some jurisdictions the clock may not start until the user recognized or should have recognized the connection between their condition and the platform design. Consulting with an attorney who specializes in product liability or consumer protection law can help individuals understand their options and the viability of a claim in their jurisdiction.
The broader legal landscape around technology addiction is also evolving. Lawsuits against social media companies for youth mental health harms have established some precedents around the duty of digital platforms to protect users from known risks. While gambling is a distinct area of law with its own regulatory framework, some of the legal theories being advanced in social media litigation may inform the sports betting cases.
Conclusion
What happened to you was not an accident. It was not bad luck or poor judgment or a character flaw. The experience you had—the escalating bets, the inability to stop, the financial devastation—was a documented outcome of deliberate design choices made by companies that built platforms to maximize engagement and revenue. According to the lawsuits now moving through the courts, these companies had research, data, and decades of gambling industry knowledge showing the addiction risks their products created. The court filings allege they saw those risks and chose profit over safety.
You deserved to know what you were getting into when you downloaded that app. You deserved clear warnings, effective safeguards, and honest information about the odds of losing and the signs of addiction. The lawsuits allege you did not receive those things because the companies determined that transparency and caution would reduce user engagement and hurt their bottom line. That was a business decision, and it had consequences. Those consequences landed on you, on your family, on your financial security and your mental health. But the responsibility for that decision does not rest with you. It rests with the companies that made it.
