You told yourself it was entertainment. A way to make the games more interesting. Five dollars here, twenty there. You had seen the commercials during every broadcast, the promos offering deposit matches and risk-free bets. Everyone seemed to be doing it. Then the bets got bigger. You started checking your phone during meetings, during dinner, during the middle of the night. You chased losses that spiraled into thousands, then tens of thousands. You lied to your spouse about where the money went. You borrowed from retirement accounts, maxed out credit cards, took cash advances you knew you could not repay. By the time you realized something was deeply wrong, you had lost everything that mattered.
Your therapist used the clinical term: gambling disorder. A recognized psychiatric condition, they explained, that changes the way your brain processes reward and risk. You felt a wave of shame. How had you let this happen? You were responsible. You had a career, a family. This was not supposed to happen to someone like you. What you did not know yet was how the platforms you used were designed. What features were built into the apps on your phone. What the companies behind them allegedly knew about how those features affected vulnerable users.
You are not alone. Thousands of people who began using sports betting apps after their nationwide expansion have found themselves unable to stop. Lives have unraveled with shocking speed. And now, lawsuits filed across the country allege that the companies operating these platforms engineered that outcome, using design features and marketing tactics that they allegedly knew would create and exploit addiction in a subset of users.
What Happened
Gambling disorder is not a matter of weak willpower or poor financial planning. It is a behavioral addiction recognized by the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders. People who develop it describe an overwhelming compulsion to keep betting despite devastating consequences. They experience withdrawal symptoms when they try to stop—restlessness, irritability, an inability to think about anything else. They lie to family members. They jeopardize jobs and relationships. Many describe a dissociative state while betting, hours disappearing while they place wager after wager, chasing losses they believe are just one bet away from being recovered.
The financial destruction can be catastrophic. Users describe losing life savings in a matter of months. Six-figure losses are common in the litigation. Some plaintiffs allege they lost their homes. Others depleted college funds meant for their children. The ease of mobile betting means there is no natural stopping point, no moment when you run out of chips and have to leave the casino. You can place bets from your car, from your bed, from the bathroom at work. The platforms allow deposits at any hour, often without meaningful limits or cooling-off periods.
The emotional toll extends beyond the user. Spouses discover secret debts. Families face bankruptcy. Relationships disintegrate under the weight of broken trust and financial ruin. Some users describe suicidal thoughts, a sense that there is no way out of the hole they have dug. What many did not understand was that the platforms they were using were allegedly designed to make this outcome more likely for vulnerable individuals.
The Connection
Sports betting apps create a gambling experience that is fundamentally different from traditional sports wagering. The litigation alleges that companies like DraftKings, FanDuel, and BetMGM incorporated specific design features that behavioral scientists have identified as particularly addictive, and that these companies had access to research showing how these features affect user behavior.
One key feature is the ability to place in-game or live bets while a sporting event is happening. Unlike traditional sports betting, where you place a wager before the game begins and wait for the outcome, in-game betting allows continuous wagering throughout the event. The odds update in real time. You can bet on the next play, the next at-bat, the next possession. This creates what addiction researchers call a high event frequency—the opportunity to experience the dopamine rush of winning or the anxiety of losing many times within a single hour. Research published in the International Gambling Studies journal has identified event frequency as one of the strongest predictors of gambling-related harm.
The platforms also use push notifications to alert users to betting opportunities. These notifications arrive on your phone unprompted, often timed to moments when games are starting or when the platform is offering a promotion. Court filings allege that these notifications are designed to trigger urges in users who might otherwise not open the app. A 2022 study in the journal Addictive Behaviors found that gambling-related notifications significantly increased betting frequency and were associated with higher rates of problem gambling.
Another feature highlighted in the litigation is the use of deposit bonuses and risk-free bet promotions. Users are offered matched deposits—the platform matches the money you put in—or bets that are advertised as risk-free, where you get your money back if you lose. These promotions are allegedly designed to give users what behavioral economists call house money effect, where people bet more aggressively with bonus funds because they do not perceive them as their own money, even though losses are ultimately borne by the user. The litigation alleges that these promotions are particularly effective at keeping users engaged past the point where they would otherwise have stopped.
The platforms also provide easy access to credit-like features. Users can deposit funds instantly using linked bank accounts or credit cards. Some platforms allegedly allowed users to bet on credit, essentially wagering money they did not have. The complaints allege that these features remove natural barriers that might otherwise limit destructive behavior, allowing losses to accumulate with terrifying speed.
Crucially, the lawsuits allege that the defendant companies had access to each user individual betting data and could identify patterns consistent with problem gambling, but failed to intervene or impose meaningful limits. The platforms allegedly tracked metrics like time spent on the app, frequency of deposits, and chasing behavior—placing increasingly large bets after losses. This data, the litigation claims, would have allowed the companies to identify users at risk and intervene, but they allegedly chose not to because those users were highly profitable.
What The Lawsuits Allege They Knew
The sports betting industry did not emerge in a vacuum. According to complaints filed in multiple jurisdictions, the defendant companies entered the United States market with full awareness of decades of international research on gambling harm and the specific design features that create addiction risk.
The lawsuits allege that the parent companies and executives behind DraftKings, FanDuel, and BetMGM had access to extensive research conducted in jurisdictions where sports betting had been legal for years, including the United Kingdom and Australia. A landmark 2016 study by the UK Gambling Commission found that in-play betting and mobile gambling were significantly associated with problem gambling rates. The research identified continuous access and high event frequency as key risk factors. According to the complaints, executives at the defendant companies were aware of this research before launching their U.S. sports betting operations.
Court filings cite internal documents that allegedly show the companies tracked user engagement metrics closely and understood which features drove the most activity. The lawsuits allege that the platforms were designed to maximize user engagement and lifetime value, metrics that the companies allegedly knew correlated with problematic use in vulnerable individuals. One complaint references a presentation allegedly created for investors that described certain users as whales—industry terminology for high-value customers who generate disproportionate revenue. The litigation alleges that the companies knew these high-value users often exhibited signs of addiction but viewed them as essential to profitability.
The complaints also point to the timing of the nationwide expansion. Following a 2018 Supreme Court decision that allowed states to legalize sports betting, the defendant companies rapidly launched operations across the country. The lawsuits allege that this expansion was conducted without adequate responsible gambling safeguards, despite the fact that the companies had access to international data showing the harm their products could cause. According to the litigation, the companies prioritized market share and customer acquisition over user safety.
FanDuel and DraftKings both operated daily fantasy sports platforms before the 2018 Supreme Court decision, and the lawsuits allege that the companies had already collected data on user behavior that should have informed their understanding of addiction risk. Daily fantasy sports had been criticized by regulators and researchers for features similar to those later incorporated into sports betting apps. According to complaints, the companies had faced scrutiny over whether their daily fantasy products constituted illegal gambling, and in the course of defending their business model, they allegedly gathered data on how users interacted with their platforms. The litigation alleges that this data showed clear patterns of problematic use but that the companies proceeded to launch sports betting products with even more addictive features.
Congressional testimony has also been cited in some complaints. In hearings held in various states considering sports betting legalization, representatives from betting companies allegedly provided assurances about responsible gambling measures. The lawsuits claim that the responsible gambling tools actually implemented—such as deposit limits and self-exclusion options—were difficult to find, cumbersome to use, and easily circumvented. According to the litigation, the companies marketed themselves as responsible operators while allegedly designing their platforms to maximize engagement among the most vulnerable users.
Court filings further allege that the companies had access to data showing that a small percentage of users generated a disproportionate share of revenue. Research from the gambling industry itself has long shown that approximately 10 to 20 percent of users account for 80 to 90 percent of revenue, and that this group has significantly higher rates of gambling disorder. The complaints allege that the defendant companies structured their business models around retaining these high-value users and that they knew or should have known that many of these users were gambling addicts.
What The Lawsuits Say About Concealment
The complaints filed against DraftKings, FanDuel, and BetMGM do not merely allege that the companies knew their platforms could cause harm. They allege a pattern of concealment and misrepresentation designed to prevent users, regulators, and the public from understanding the true risks.
One area of alleged concealment involves the marketing of responsible gambling tools. The companies prominently advertise features like deposit limits, time limits, and self-exclusion options in their public messaging and regulatory filings. However, the lawsuits allege that these tools were designed to be ineffective. Court filings claim that the tools are buried in settings menus, require multiple steps to activate, and can be easily disabled. Some complaints allege that users who attempted to set deposit limits were offered bonuses or promotions that effectively overrode those limits. Others allege that users who self-excluded from one platform were able to immediately open accounts on sister platforms operated by the same parent company.
The litigation also alleges that the companies misrepresented the nature of their products in marketing materials. Advertisements emphasize entertainment, social connection, and the skill involved in sports betting. According to the complaints, this marketing allegedly obscures the addictive nature of the platforms and creates a false impression that betting is a low-risk recreational activity. The lawsuits cite commercials featuring celebrities and athletes that aired during sporting events, often accompanied by offers of risk-free bets and deposit matches. The litigation alleges that these promotions were designed to appeal to casual sports fans who had no prior gambling experience and no understanding of addiction risk.
Court filings further allege that the companies lobbied aggressively to shape the regulatory environment in ways that favored their business interests over public health. According to the complaints, the defendant companies pushed for light-touch regulation in states considering sports betting legalization, arguing that heavy-handed rules would drive users to illegal offshore sites. The lawsuits allege that this lobbying effort resulted in regulations that impose minimal restrictions on advertising, deposit limits, and responsible gambling measures. Some complaints cite campaign contributions and lobbying expenditures as evidence of the companies alleged efforts to influence the regulatory process.
The litigation also raises allegations about data practices. The complaints allege that the companies collected granular data on user behavior but did not disclose how that data was used to identify and target vulnerable users. Court filings claim that the platforms used algorithms to send targeted promotions to users showing signs of problem gambling, such as frequent deposits or chasing losses. According to the lawsuits, this targeting was concealed from users and regulators and constituted an unfair and deceptive practice.
Some complaints allege that the companies entered into settlements with individual users that included non-disclosure agreements, preventing those users from speaking publicly about their experiences or the harms they suffered. According to the litigation, these NDAs were used to suppress information about the scope of gambling-related harm and to prevent patterns of wrongdoing from becoming visible to regulators or the public.
Why Your Doctor May Not Have Told You
When you started using sports betting apps, no one warned you that you might be at risk for developing a gambling disorder. Your primary care physician never asked about your gambling habits. There was no screening tool, no informed consent, no list of warning signs to watch for. This silence is not an accident.
Gambling disorder has historically been under-recognized in medical settings. Unlike substance use disorders, which are routinely screened for in primary care, gambling addiction is often invisible to healthcare providers unless a patient specifically raises the issue. Many physicians receive little to no training on gambling disorder during medical school or residency. There is no prescription to fill, no lab test to order, no physical symptom that prompts a referral. As a result, people suffering from gambling addiction often go undiagnosed until the consequences become catastrophic.
The lawsuits allege that the defendant companies benefited from this gap in medical awareness and did nothing to close it. According to court filings, the companies could have funded public health campaigns to educate physicians and the public about the signs of gambling disorder. They could have included prominent warnings in their apps or required users to complete screenings before opening accounts. The litigation alleges that they chose not to do these things because widespread awareness of gambling harm would have hurt their business model.
The complaints also allege that the companies shaped public perception of gambling in ways that minimized the appearance of risk. By emphasizing skill, strategy, and entertainment, the marketing allegedly framed sports betting as fundamentally different from casino gambling or slot machines, which carry a stronger stigma. According to the lawsuits, this framing made it less likely that users would recognize their own behavior as problematic or seek help.
Furthermore, the litigation alleges that the speed with which sports betting expanded across the United States outpaced the ability of public health infrastructure to respond. Researchers, clinicians, and regulators are still working to understand the scope of the problem and develop effective interventions. The complaints allege that the defendant companies pushed for rapid legalization and market penetration before adequate safeguards were in place, leaving users exposed to serious harm without adequate support or information.
Who Is Affected
If you developed a gambling problem after using DraftKings, FanDuel, BetMGM, or similar sports betting platforms, you are not alone, and what happened to you was not a personal failing.
The lawsuits involve people who had no prior history of gambling problems. Many were casual sports fans who saw an advertisement during a game and decided to try it out. Some were attracted by promotions offering free bets or matched deposits. Others were drawn in by the social aspect, the ability to compete with friends or participate in the communal experience of watching sports.
What many have in common is a rapid escalation. People describe starting with small wagers and finding themselves, within months, betting amounts they could not afford to lose. They describe using the apps constantly, checking odds throughout the day, placing bets impulsively. They describe the sick feeling of watching their bankroll disappear and then depositing more, convinced they could win it back.
The financial losses vary but are often staggering. Some people lost tens of thousands of dollars. Others lost hundreds of thousands. The litigation includes plaintiffs who depleted retirement accounts, took out loans, borrowed from family members, and engaged in illegal activity to fund their betting. Many did not seek help until they had lost everything.
If you have experienced significant financial losses from sports betting, if your use of betting apps caused problems in your relationships or at work, if you found yourself unable to stop despite wanting to, if you lied about your gambling or hid it from people you love, you may have been harmed by the practices alleged in these lawsuits.
The people affected come from all demographics. The litigation includes professionals, tradespeople, retirees, young adults. Some were experienced bettors who found that mobile betting apps were different in kind from anything they had encountered before. Others had never placed a bet in their lives before downloading an app. What unites them is the experience of being caught in a cycle they did not understand and could not escape, facilitated by platforms that allegedly knew exactly what they were doing.
Where Things Stand
Litigation against sports betting companies is underway in multiple jurisdictions. Lawsuits have been filed against DraftKings, FanDuel, BetMGM, and other operators in state and federal courts. The complaints assert a variety of legal theories, including negligence, fraud, unjust enrichment, and violations of consumer protection statutes.
Some cases have been consolidated into multidistrict litigation to streamline pretrial proceedings. Discovery is ongoing in many cases, with plaintiffs seeking internal documents, communications, and data that would reveal what the companies knew about the addictive nature of their platforms and when they knew it. The defendants have filed motions to dismiss in several cases, arguing that users are responsible for their own gambling behavior and that the companies are protected by regulatory frameworks established by state gaming authorities.
The litigation is in its early stages, and no major settlements or verdicts have been reached as of this writing. However, the volume of cases is growing. Attorneys representing plaintiffs have indicated that they are reviewing thousands of potential claims. The legal theories being advanced are novel in some respects, as sports betting apps represent a relatively new product, but they build on established principles of product liability and consumer protection law.
Some courts have allowed cases to proceed past the motion to dismiss stage, finding that plaintiffs have adequately alleged that the defendant companies engaged in deceptive practices and failed to warn users of known risks. Other courts have dismissed claims, holding that gambling losses are a known risk of betting and that users cannot hold platforms liable for their own choices. The outcomes vary by jurisdiction and by the specific legal claims asserted.
In addition to civil litigation, there is growing regulatory scrutiny. Some state legislatures have held hearings on sports betting harm and are considering stricter regulations on advertising, deposit limits, and responsible gambling measures. Advocacy groups have called for federal oversight of the industry. Researchers are publishing studies on the public health impact of mobile sports betting, and the findings are beginning to inform policy debates.
For individuals considering legal action, the timeline depends on the jurisdiction and the stage of litigation. Some cases may take years to resolve. Others may result in earlier settlements if the discovery process reveals damaging internal documents. The strength of any individual claim depends on the specific facts, including the extent of financial harm, the duration and nature of platform use, and the evidence linking the harm to the alleged wrongful conduct of the defendant companies.
The litigation is not only about compensation for individuals who were harmed. It is about accountability. The lawsuits seek to expose what the companies knew and when they knew it, and to force changes in the design and marketing of sports betting platforms to prevent future harm.
You did not lose control because you lack discipline. You did not destroy your finances because you are reckless. What happened to you occurred in the context of platforms that were allegedly designed, tested, and refined to be as engaging as possible, by companies that allegedly had data showing exactly who was most vulnerable and chose profit over safety. The litigation is attempting to bring that reality into the light. What you experienced was not random. It was a documented business decision. And you are not alone in seeking accountability for what was taken from you.
