You told yourself you would stop after one more bet. Then one more after that. The app was right there on your phone, glowing with promise, vibrating with notifications about games starting soon, odds shifting in your favor, free bets waiting to be claimed. What started as entertainment during commercial breaks became something you thought about during meetings, at dinner, in bed at night. You borrowed money you could not repay. You lied to people you love. You felt a physical urgency to place a bet that overrode every rational thought about consequences. When you finally admitted you had lost control, you assumed it was a personal failure, a character flaw, weakness you should have overcome.
Your therapist or counselor may have diagnosed you with gambling disorder, a recognized condition in the Diagnostic and Statistical Manual of Mental Disorders. They may have explained that your brain had been altered by repeated exposure to variable reward schedules, that the dopamine pathways involved in addiction had been activated in ways that made stopping feel neurologically impossible. They may have told you this was not about willpower. But they probably did not tell you what the lawsuits now allege: that the platforms you used were designed, with scientific precision, to produce exactly this outcome.
The apps did not feel like the casinos your grandparents visited. There were no smoke-filled rooms, no long drives, no social stigma of walking through casino doors. This was sports, something you had enjoyed your whole life, now enhanced with a layer of engagement that felt participatory, skillful, social. The platforms were integrated into sports media, endorsed by leagues and celebrities, advertised during family programming. They offered deposit matches, risk-free bets, odds boosts, and loyalty programs that made continued play feel financially rational. What you may not have known was what the lawsuits now claim: that behind the interface were systems built to maximize what the industry calls time on device and lifetime value, using behavioral design techniques that the companies allegedly knew could trigger and sustain compulsive use.
What Happened
Gambling disorder is a behavioral addiction that changes how your brain processes reward, risk, and decision-making. It typically progresses through stages. At first, betting feels exciting and voluntary. You win sometimes, maybe even have a good run that makes the activity feel profitable or at least sustainable. Then the losses start to accumulate. You begin chasing those losses, convinced that the next bet will bring you back to even. The amounts you wager increase. The frequency increases. You start betting on sports or events you know nothing about, just to have action.
The psychological experience becomes consuming. You feel restless or irritable when you try to cut back. You lie about how much you are betting or how much you have lost. You jeopardize relationships, jobs, or educational opportunities because of betting. You rely on others to provide money to relieve desperate financial situations caused by gambling. The emotional cycle becomes punishing: anticipation and hope before a bet, brief euphoria if you win, crushing despair and shame when you lose, followed immediately by the urge to bet again to escape those feelings.
For many people who developed gambling disorder through sports betting apps, the financial devastation came with alarming speed. Credit cards maxed out within months. Savings accounts drained. Loans taken from family members under false pretenses. Some people describe betting thousands of dollars in a single evening, amounts that once would have seemed unthinkable, placed in a fog of compulsion through an interface that made wagering feel as frictionless as liking a social media post.
The relationships suffer distinctively. Partners describe discovering secret accounts, hidden debts, lies layered upon lies. The person with gambling disorder often isolates, retreating into the app and away from the people who notice the change. Some lose their jobs due to betting during work hours or missing work entirely during periods of heavy losses. Others describe suicidal thoughts when the financial consequences became inescapable. This is not recreational entertainment gone slightly too far. This is a diagnostic condition that destroys lives with a velocity that people who lived through it describe as shocking.
The Connection
Sports betting apps produce gambling disorder through design features that behavioral scientists have studied for decades. The litigation alleges that the defendant companies employed these features knowing their potential to create compulsive use.
The core mechanism involves variable ratio reinforcement schedules, the most addiction-inducing reward pattern known to behavioral psychology. When rewards come unpredictably, after varying amounts of effort, the brain releases dopamine not just when you win but in anticipation of possibly winning. This is why slot machines are more addictive than games with predictable patterns. Sports betting apps apply this principle continuously: outcomes are uncertain, payouts vary, and the next bet always holds the possibility of a large win. Research published in the journal Addiction in 2020 found that the structural characteristics of online gambling, including event frequency and reward proximity, significantly predicted problematic gambling behavior.
The apps amplify this effect through design features the lawsuits describe in detail. Push notifications alert users to betting opportunities throughout the day, creating repeated triggers that interrupt other activities and prompt the urge to bet. In-play or live betting allows users to place wagers continuously during a game, on events as granular as the next pitch or the next play, transforming a three-hour game into hundreds of discrete gambling opportunities. A study published in the International Gambling Studies journal in 2021 found that in-play betting was associated with significantly higher rates of gambling problems compared to traditional pre-game betting, with researchers noting that the continuous nature of the activity and the illusion of control it provided were key risk factors.
The platforms also employ near-miss engineering. Bets that almost win, such as a parlay where four of five legs hit, produce a psychological response similar to winning, encouraging continued play. The apps highlight these near-misses prominently, framing devastating losses as exciting close calls. Losses are often disguised as wins through features like bonus bets and free bet credits, which feel like rewards but require further wagering to access any real value, a cycle that keeps users engaged even as their actual cash balance declines.
Deposit bonuses and promotional offers create a sunk-cost fallacy. When you deposit two hundred dollars and receive a two hundred dollar bonus, you feel you have four hundred dollars in value that you must play through to claim. The playthrough requirements ensure extended engagement, increasing exposure to the variable reward schedules that drive compulsive behavior. Research published in the Journal of Gambling Studies in 2019 found that promotional offers were significantly associated with increased gambling intensity and that users who engaged with promotions showed higher rates of problem gambling indicators.
The social features create additional pressure. Leaderboards, shared bets, and social media integration turn gambling into a community activity, normalizing constant engagement and creating fear of missing out. The apps also collect extensive data on user behavior, tracking which features each person responds to, when they are most likely to bet, and what kinds of incentives bring them back after periods of inactivity. The lawsuits allege that this data was used to personalize nudges and offers in ways designed to maximize continued play, even for users showing signs of problem gambling.
What The Lawsuits Allege They Knew
The lawsuits filed against DraftKings, FanDuel, and BetMGM allege that these companies were aware of the addictive potential of their platform design choices and made business decisions that prioritized user engagement and revenue over safety.
According to court filings, the sports betting industry has had access to decades of research on gambling addiction and the specific design features that increase risk. A landmark study published in the journal Addiction in 2005 identified structural characteristics of gambling products that increase addictive potential, including event frequency, continuity of play, and the use of electronic payment methods that obscure spending. The research was widely disseminated in the gambling industry, and the lawsuits allege that companies entering the United States sports betting market after the 2018 Supreme Court decision in Murphy v. NCAA were aware of these findings.
The complaints cite internal corporate documents, disclosed through discovery in various cases, that allegedly show the companies tracked metrics related to compulsive use. According to the litigation, the platforms monitored user engagement patterns that are recognized markers of problem gambling, such as rapidly increasing bet frequency, late-night or early-morning betting, and attempts to recover losses through progressively larger wagers. The lawsuits allege that rather than using this information to intervene, the companies used it to identify high-value users and to optimize features that would keep those users engaged.
One complaint references a 2021 presentation disclosed in litigation that allegedly outlined strategies for increasing lifetime value, the industry term for total revenue extracted from each user. According to the filing, the presentation discussed tactics for re-engaging users who had reduced their betting activity, including personalized bonus offers and strategic push notifications. The lawsuit alleges that the companies knew these re-engagement tactics were particularly effective on users exhibiting signs of problem gambling, who were statistically more likely to respond to inducements to continue betting.
The lawsuits also point to testimony before state legislatures during the legalization debates between 2018 and 2023. According to court filings, company representatives testified about responsible gambling commitments and harm-minimization features, while allegedly omitting information about design features known to increase addiction risk. A complaint filed in 2024 alleges that DraftKings representatives testified before the New York State Legislature in 2021 about robust responsible gaming tools, while internal documents from the same period allegedly showed that fewer than two percent of users ever accessed those tools and that the tools were deliberately designed to be difficult to find and cumbersome to use.
Court filings describe the regulatory submissions made by these companies to state gaming commissions. The lawsuits allege that these submissions included assurances about player protection while omitting data the companies possessed about rates of problem gambling among their users. A complaint alleges that FanDuel submitted an application to the Michigan Gaming Control Board in 2020 that included responsible gambling policies, while internal data from the same period allegedly showed that a significant percentage of the company revenue came from users whose betting patterns met clinical criteria for gambling disorder.
The complaints also reference academic partnerships that the lawsuits allege were structured to generate favorable research. According to court filings, BetMGM and other operators provided funding to university research programs studying gambling behavior, with agreements that allegedly gave the companies input into research design and early access to findings. The lawsuits claim that studies producing results unfavorable to the industry were not published, while studies that minimized addiction risks or emphasized user autonomy were promoted in regulatory proceedings and media coverage. A 2023 investigation by journalists published in The New York Times examined these research relationships and found that several prominent gambling researchers had undisclosed financial ties to sports betting companies, raising questions about the independence of their findings.
What The Lawsuits Say About Concealment
The litigation alleges that the sports betting companies engaged in a pattern of concealment and misdirection regarding the addictive risks of their products.
According to court filings, the industry trade group iDEA Growth, which includes DraftKings and FanDuel as members, lobbied extensively against mandatory responsible gambling features during state legalization efforts. The lawsuits allege that the group opposed requirements for deposit limits, mandatory time-outs, and algorithms that would detect and intervene with problem gambling patterns. A complaint filed in Massachusetts district court in 2024 claims that internal emails disclosed in discovery show industry representatives coordinating messaging to state regulators that emphasized personal responsibility and user choice, while allegedly working behind the scenes to defeat measures that would have reduced platform engagement.
The complaints describe the responsible gambling tools that were implemented as inadequate by design. The lawsuits allege that deposit limits and self-exclusion features were deliberately made difficult to locate within the apps, requiring users to navigate through multiple menus to access them. According to court filings, companies conducted user experience testing that allegedly showed these tools were rarely used, but rather than making them more prominent, the companies kept them buried. A complaint alleges that a 2022 internal DraftKings document referred to responsible gambling features as friction and discussed strategies for minimizing user exposure to them.
The litigation also alleges that the companies suppressed negative user experiences through non-disclosure agreements. According to court filings, users who contacted customer service about gambling problems and requested account closures were sometimes offered settlement payments in exchange for signing agreements that prevented them from discussing their experiences publicly or participating in litigation. The lawsuits claim this practice prevented regulators, researchers, and the public from understanding the true scope of addiction problems associated with the platforms.
Court filings point to the marketing strategies that the lawsuits allege were designed to normalize excessive gambling and to obscure risks. Advertisements featuring celebrities and athletes portrayed betting as a routine part of sports fandom, with no mention of addiction potential. The complaints cite ad campaigns that encouraged daily betting, promoted parlays with astronomical odds as realistic opportunities, and offered bonuses that required continued play. According to the litigation, the companies spent billions on advertising to establish market share, knowing that heavy advertising of gambling products is associated with increased problem gambling rates. A study published in the Journal of Public Health in 2022 found that exposure to gambling advertising was significantly associated with gambling participation and problem gambling severity, particularly among young adults.
The lawsuits also allege that the companies targeted vulnerable populations. Court filings claim that marketing disproportionately reached young men, a demographic known to have higher rates of problem gambling, through advertising during sports programming, on social media platforms, and through partnerships with sports leagues and teams. According to the complaints, internal marketing documents allegedly segmented users by risk profile, with high-value users, many of whom displayed problem gambling behaviors, receiving personalized offers designed to maximize their continued engagement.
Why Your Doctor May Not Have Told You
Most primary care physicians receive little to no training in recognizing or treating gambling disorder. Medical school curricula focus on substance use disorders, and gambling addiction is often omitted entirely or covered in a single lecture. Even mental health professionals may have limited familiarity with the condition, particularly the new patterns emerging from app-based sports betting, which differs significantly from casino gambling in its accessibility, frequency, and social context.
The sports betting industry has also shaped public understanding in ways that the lawsuits allege minimized perceived risks. The marketing and public messaging emphasized skill, strategy, and sports knowledge, framing betting as an extension of fandom rather than as gambling. This framing, the complaints allege, was deliberate. By distinguishing sports betting from casino gambling in public perception, the companies avoided the stigma and regulatory scrutiny associated with traditional gambling products. Many users, and even healthcare providers, did not initially recognize app-based sports betting as carrying the same addiction risks as slot machines or poker.
The lawsuits allege that the companies also influenced medical and public health discourse through funded research and partnerships with advocacy organizations. According to court filings, industry money flowed to nonprofit organizations focused on responsible gambling, with funding agreements that allegedly gave companies influence over messaging and policy positions. The complaints claim that these organizations promoted education and personal responsibility frameworks while opposing regulatory interventions that would have limited platform features known to increase addiction risk.
There is also the issue of speed. Gambling disorder from sports betting apps can develop rapidly, in some cases within months of starting to use the platform. Many healthcare providers are accustomed to thinking of addiction as a condition that develops over years. By the time someone seeks help, they may already be in financial crisis, and the focus of medical attention may be on the resulting depression, anxiety, or suicidal ideation rather than on the underlying gambling disorder. The lawsuits allege that the companies were aware that their platforms could produce addiction quickly, but did not warn users or healthcare providers about this risk.
Additionally, the apps exist in a regulatory environment that is still developing. Unlike pharmaceuticals, which require disclosure of risks and side effects, gambling platforms have faced limited requirements to warn users about addiction potential. The lawsuits allege that the companies lobbied to keep warning requirements minimal and voluntary. In states where warnings were required, the complaints claim the companies used vague language and small fonts, placing warnings in locations within the app where user testing allegedly showed they would be least noticed.
Who Is Affected
You may be affected by the issues raised in these lawsuits if you used DraftKings, FanDuel, BetMGM, or other sports betting apps and subsequently developed gambling disorder or experienced significant harm related to your betting activity.
The litigation is focusing on people who created accounts on these platforms after they launched in your state, which for most states was between 2018 and 2023, following the Supreme Court decision that allowed states to legalize sports betting. If you downloaded one of these apps, deposited money, and began betting on sports, and your use escalated in ways that caused harm, you may have a relevant experience.
The pattern typically looks like this: You started betting small amounts, maybe during football season or March Madness. The app offered you bonuses for depositing money, matching your deposit or giving you free bets. You won sometimes, which felt exciting and made the activity seem potentially profitable. Over time, you found yourself betting more frequently, on more games, on sports you did not follow closely. You started betting larger amounts to chase losses or to feel the same excitement you felt initially. You began using the app daily, or multiple times per day, checking odds, placing live bets during games, feeling anxious when you could not bet.
The harm can manifest in various ways. Financial harm is common: significant debt, depleted savings, unpaid bills, borrowing money you could not repay, selling possessions, taking out loans or cash advances. Relationship harm includes lying to family members or partners about betting activity, withdrawal from social connections, conflicts related to money or time spent on the app. Occupational or educational harm might involve betting during work or school, declining performance, or job loss. Psychological harm includes depression, anxiety, shame, hopelessness, or suicidal thoughts related to gambling losses.
Many people meeting these criteria were diagnosed with gambling disorder by a mental health professional, using criteria from the DSM-5, which includes symptoms like needing to bet increasing amounts to achieve the desired excitement, restlessness or irritability when trying to cut down, repeated unsuccessful efforts to control or stop gambling, preoccupation with gambling, gambling when feeling distressed, chasing losses, lying about gambling, jeopardizing relationships or opportunities because of gambling, and relying on others for money to relieve financial situations caused by gambling. A diagnosis typically requires meeting four or more of these criteria within a twelve-month period.
But you do not necessarily need a formal diagnosis to be affected. If you used these apps and experienced significant harm, if you felt unable to control your use despite negative consequences, if you recognize your experience in the patterns described in the litigation, your experience may be relevant. This includes people who have sought treatment for gambling disorder, those who have self-excluded from betting platforms, those who have experienced financial devastation even if they have not yet sought mental health treatment, and those whose relationships or careers were damaged by betting activity that felt compulsive.
The lawsuits also focus on the timeframe and jurisdiction. If you used these apps in states where sports betting was legal and where the companies operated, and if your problematic use occurred after the platforms launched in your state, the timing aligns with the litigation. Some cases involve people who had never gambled before using sports betting apps, while others involve people who had gambled recreationally in the past but experienced a rapid escalation in frequency and severity after downloading these specific platforms.
Where Things Stand
Litigation against sports betting companies is in relatively early stages, with cases filed in multiple state and federal courts beginning in 2023 and increasing in number through 2024 and 2025. The legal theories involve product liability, consumer protection violations, negligence, and fraud, with plaintiffs alleging that the companies designed inherently dangerous products, failed to warn about known risks, targeted vulnerable users, and misrepresented the safety and nature of their platforms.
Several cases have survived motions to dismiss, allowing discovery to proceed. This has resulted in the disclosure of internal documents that the lawsuits cite extensively, including communications about user engagement strategies, data about problem gambling rates among users, and marketing plans. Some of these documents have been filed under seal, but portions have been referenced in publicly available court filings, forming the basis for many of the allegations described in the complaints.
In late 2024, a case in Massachusetts state court resulted in a significant development when a judge allowed claims to proceed against DraftKings related to alleged unfair and deceptive practices under state consumer protection law. The ruling found that the plaintiffs had adequately alleged that the company employed design features known to be addictive and failed to adequately warn users about these risks. The case is proceeding to discovery and potentially to trial.
Several other cases are coordinated in multidistrict litigation in federal court, consolidating cases from multiple jurisdictions for pre-trial proceedings. This coordination is intended to streamline discovery and avoid duplicative litigation on common factual questions. The MDL is in the discovery phase, with document production ongoing and depositions of company executives and designers scheduled.
There have not yet been jury verdicts or significant settlements in sports betting addiction cases, but attorneys involved in the litigation have indicated that the internal documents obtained in discovery support the allegations in the complaints. Legal observers have noted parallels to earlier litigation against tobacco companies, opioid manufacturers, and social media platforms, where internal documents revealed corporate knowledge of harms and strategic decisions to prioritize profit over safety.
The legal landscape is also evolving at the regulatory level. Some states have begun implementing stronger responsible gambling requirements in response to growing evidence of addiction problems, including mandatory deposit limits, enhanced self-exclusion programs, and restrictions on certain types of advertising. The lawsuits allege that the companies are opposing many of these measures through lobbying efforts, but public awareness of sports betting addiction has increased significantly, partly due to media coverage of the litigation and partly due to the visible human toll.
New cases continue to be filed as more people come forward with experiences of gambling disorder linked to these platforms. The litigation is not limited to the three named defendants; other sports betting operators, including Caesars, Penn Entertainment, and others, face similar claims. The outcomes of the early cases will likely shape the trajectory of the broader litigation and may influence whether companies choose to settle or continue to defend the cases in court.
What This Means
If you developed gambling disorder after using a sports betting app, what happened to you was not a failure of character or willpower. The experience you had, the loss of control, the inability to stop despite devastating consequences, was the result of systems designed to produce exactly that outcome. The lawsuits allege, with supporting documentation, that these companies knew what they were building and understood the human cost.
The shame you carry, the belief that you should have been able to stop, the isolation that came from hiding what was happening, all of it was compounded by a public narrative that framed this as entertainment, as a harmless enhancement to watching sports. That narrative, the lawsuits allege, was constructed deliberately to obscure the reality of what these products do to human brains. You were not weak. You were exposed to one of the most powerful behavioral manipulation systems ever deployed at population scale, delivered through a device in your pocket, engineered by people who allegedly understood exactly what they were doing.
