You downloaded the app because it looked like fun. Everyone was talking about it. The ads were everywhere during the game, and they made it sound simple: put a little money down, make the game more exciting, maybe win something. You told yourself you would only bet what you could afford to lose. You had a budget. You were just having fun with friends.
But somewhere along the way, something changed. You started checking the app between meetings at work. You found yourself betting on games you did not even care about, sports you never watched before, just to have action running. You chased losses that kept growing. You lied to your spouse about where the money went. You borrowed from your retirement account, your credit cards, then from family members with excuses that felt shameful even as you said them out loud. By the time you realized you could not stop, you had lost tens of thousands of dollars, maybe more. Your relationships were shattered. You felt completely alone.
If that describes your experience, what happened to you has a name. It is called gambling disorder, and it is a recognized psychiatric condition. The shame you feel, the isolation, the belief that you should have been strong enough to just stop—none of that changes what the litigation now alleges: that the companies behind these apps built platforms using psychological techniques designed to keep you betting, and that internal research may have shown them exactly how addictive their products could be.
What Happened
Gambling disorder is not about being weak or lacking willpower. It is a behavioral addiction that changes the way your brain processes reward, risk, and decision-making. People who develop gambling disorder describe it as an overwhelming compulsion to keep betting despite devastating consequences. You know the harm it is causing. You see your bank account emptying, your relationships crumbling, your work performance declining. But you cannot stop.
The experience often follows a pattern. It starts with early wins that feel exciting and easy. The apps celebrate your victories with sounds, graphics, and notifications that flood your brain with dopamine. You start to believe you have a system, that you can predict outcomes, that the next bet will be the one that gets you back to even. But losses mount faster than wins, and that creates a psychological trap: you feel desperate to recover what you lost, so you bet more, and the cycle intensifies.
People with gambling disorder describe intrusive thoughts about betting that interrupt their daily lives. You think about odds while trying to focus on work. You plan your next bet while sitting at dinner with family. You wake up in the middle of the night with your heart racing, calculating how much you have lost and what you might bet tomorrow to win it back. The apps are always there, always accessible, offering instant action twenty-four hours a day.
The financial devastation can be catastrophic. People drain savings accounts built over decades. They max out credit cards, take out personal loans, borrow against their homes. Some file for bankruptcy. Others lose their homes entirely. The shame and secrecy that accompany gambling disorder mean that by the time family members discover the extent of the damage, the financial hole is often insurmountable.
Relationships collapse under the weight of broken trust. Spouses discover lies about hidden accounts and secret debts. Children watch their parents deteriorate emotionally and financially. Friendships end when borrowed money is never repaid. The isolation deepens because admitting the problem feels impossible when you are drowning in shame.
Some people who develop severe gambling disorder experience suicidal thoughts. The combination of financial devastation, destroyed relationships, and overwhelming shame can feel like a trap with no exit. If you have felt this way, you need to know: you are not alone, and what happened to you may not have been an accident.
The Connection
Online sports betting platforms are different from walking into a casino or buying a lottery ticket. The apps use design features and psychological techniques that scientific research has linked to increased addiction risk. The lawsuits allege that these companies knew about this research and designed their products accordingly.
The apps are built on a principle called variable ratio reinforcement, a concept studied extensively in behavioral psychology. This is the same mechanism that makes slot machines so addictive. You do not win every time, but you win often enough and unpredictably enough that your brain stays locked in a cycle of anticipation and reward. The uncertainty itself becomes addictive because your brain releases dopamine not just when you win, but in anticipation of possibly winning.
A study published in the journal Addictive Behaviors in 2020 examined the structural characteristics of online gambling platforms and found that features like instant bet placement, continuous opportunities to gamble, and ambient sound and visual effects were associated with higher rates of problem gambling. The researchers noted that these features are especially pronounced in mobile betting apps, where users can place bets in seconds without any pause or friction in the process.
Sports betting apps eliminated the natural breaks that once existed in gambling. You do not have to drive to a casino. You do not have to wait for a weekly card game. You do not even have to wait for the game to start. Live in-game betting allows you to place wagers continuously throughout a sporting event, on everything from the next pitch to the next timeout. The apps offer hundreds of betting options at any given moment, creating a state of continuous action.
Push notifications bring the app back to your attention throughout the day. You receive alerts about games starting, odds changing, promotional offers expiring, and bonuses available. Each notification is a prompt to open the app and place another bet. Research published in the Journal of Behavioral Addictions in 2019 found that push notifications from gambling apps were associated with increased gambling frequency and higher scores on problem gambling screens.
The apps also use sophisticated personalization algorithms. They track your betting history, your preferences, your winning and losing patterns. They offer you bonuses and promotions tailored to your behavior, designed to bring you back when you have not bet in a while or to keep you engaged when you are active. A 2021 study in the International Journal of Mental Health and Addiction found that personalized marketing in online gambling was associated with greater gambling involvement and higher risk of harm.
Free bets and bonus offers create what researchers call illusory control—the feeling that you are playing with house money, that the risk is lower, that you have an advantage. But the terms of these promotions often require you to bet far more than the value of the bonus before you can withdraw any winnings. They function as a mechanism to increase your total volume of betting, which increases the house edge and your likelihood of loss.
For people with certain vulnerabilities, these design features can trigger the neurological changes associated with addiction. Brain imaging studies have shown that people with gambling disorder show altered activity in regions of the brain involved in reward processing, impulse control, and decision-making. The constant stimulation, the rapid feedback, the variable rewards—all of these features interact with your brain chemistry in ways that can create compulsive behavior.
The accessibility of mobile betting apps also removes barriers that once provided natural limits. You can bet from your couch, from your office, from your car. You can bet while intoxicated, while emotionally distressed, while already deep in losses. There is no casino employee watching your behavior, no friend next to you suggesting you take a break. The app never cuts you off. It never suggests you have had enough. It just keeps offering you more options to bet.
What The Lawsuits Allege They Knew
Court filings in ongoing litigation against DraftKings, FanDuel, and BetMGM allege that these companies were aware of research linking their platform design features to addiction risk, and that they made business decisions that prioritized user engagement and revenue over consumer safety.
The complaints cite testimony before state legislatures during the period when sports betting was being legalized across the United States following the 2018 Supreme Court decision in Murphy v. NCAA. Lawsuits allege that while company representatives testified publicly about responsible gaming commitments, internal business strategies focused on maximizing user engagement metrics and customer lifetime value.
A 2022 complaint filed in the United States District Court for the District of Massachusetts alleges that DraftKings employed data scientists and behavioral psychologists who analyzed user behavior to optimize the platform for increased betting frequency. The lawsuit claims that the company tracked metrics including session length, bet velocity, and return visit rates, and that product development decisions were made with the goal of increasing these engagement measures.
Court filings cite internal documents allegedly disclosed in discovery that describe A/B testing of notification strategies, bonus structures, and interface designs. The lawsuits allege that these tests measured which variations produced higher user engagement and betting volume, and that the winning variations were implemented across the platform even when they incorporated features that research had linked to addiction risk.
Similar allegations have been made regarding FanDuel. A 2023 complaint filed in New Jersey alleges that FanDuel received reports through its customer service channels from users describing compulsive betting behavior and requests for help, and that the company continued to send promotional offers to those users. The lawsuit claims that FanDuel's responsible gaming tools were difficult to find in the app interface and that users who set deposit limits were sometimes offered promotions that encouraged them to increase those limits.
Congressional testimony from a 2023 hearing before the House Committee on Energy and Commerce included statements from researchers who studied the sports betting industry. One witness testified that the industry employs many of the same behavioral design techniques that social media companies have faced criticism for using, including variable reward schedules, social comparison features, and algorithmic personalization designed to maximize time spent on the platform.
The lawsuits allege that all three major companies—DraftKings, FanDuel, and BetMGM—had access to published research on gambling addiction and online gambling harm that predated the launch of their mobile sports betting platforms. A 2017 review published in the journal Current Addiction Reports summarized decades of research on structural characteristics of gambling products and concluded that continuous, rapid, and convenient forms of gambling were associated with the highest rates of harm. The litigation alleges that this research was publicly available and known to the industry during the period when these apps were being designed and deployed.
Court filings also point to the companies' own responsible gambling pages and disclosures, arguing that the existence of warnings about addiction risk demonstrates corporate awareness that their products posed such risks. The lawsuits allege that despite this stated awareness, the companies dedicated vastly more resources to user acquisition and engagement optimization than to harm prevention.
Plaintiffs cite advertising spending as evidence of corporate priorities. According to market research data referenced in the complaints, the online sports betting industry spent over two billion dollars on advertising in 2021 and 2022 combined. The lawsuits allege that this massive marketing campaign, which saturated sports broadcasts and online media, was designed to normalize sports betting and recruit new users at a scale and speed that would inevitably include large numbers of vulnerable individuals.
The litigation also references the use of celebrity endorsers and partnerships with professional sports leagues and teams. The complaints allege that these partnerships were designed to create an association between sports betting and mainstream sports fandom, making betting seem like a normal part of watching sports rather than a high-risk activity that causes serious harm to a significant percentage of users.
What The Lawsuits Say About Concealment
The complaints allege that sports betting companies have not been transparent with users or regulators about the addictive potential of their products or about internal data regarding user harm.
Lawsuits claim that the companies collect extensive data on user behavior, including data that could identify patterns consistent with problem gambling, but that this data has not been shared with independent researchers or public health authorities. The complaints allege that while the companies tout their commitment to responsible gaming, they have not disclosed what percentage of their revenue comes from users who meet criteria for gambling disorder or problem gambling.
Research in other gambling markets provides context for why this data matters. A widely cited study of casino gambling found that a small percentage of heavy users accounted for a disproportionate share of total revenue. Studies of online gambling in European markets where more data is available have found similar patterns. The lawsuits allege that sports betting companies in the United States possess data that would show similar concentration of revenue among heavy users, and that disclosure of this data would reveal the extent to which the business model depends on users who are gambling at harmful levels.
The complaints also allege that the companies have used mandatory arbitration clauses and non-disclosure agreements to keep disputes and settlements confidential. Lawsuits claim that users who have experienced harm and sought legal recourse have been forced into private arbitration where outcomes are not made public, preventing patterns of harm from becoming visible to regulators, researchers, or other consumers.
Court filings cite the limited availability of detailed responsible gaming data in company financial disclosures and investor presentations. The lawsuits allege that while the companies report overall user numbers and revenue figures to investors, they do not disclose metrics related to problem gambling prevalence among their user base, the effectiveness of responsible gaming tools, or the volume of customer complaints related to addiction and financial harm.
Some complaints reference regulatory frameworks in other jurisdictions that require more extensive harm monitoring and disclosure. In the United Kingdom, gambling operators are required to conduct social responsibility assessments and to share data with the Gambling Commission. The lawsuits allege that sports betting companies operating in the United States have resisted similar oversight and transparency measures in state regulatory proceedings.
The litigation also raises allegations about the funding of research. Court filings claim that the industry has provided funding to academic researchers and policy organizations studying gambling, and that this industry funding may influence research questions, methodology, and conclusions in ways that favor industry interests. The complaints cite examples from other industries, including pharmaceutical and tobacco, where industry-funded research was later shown to have understated risk or overstated safety.
Plaintiffs further allege that the companies have lobbied state legislatures to adopt regulatory frameworks that favor industry growth over consumer protection. The lawsuits claim that during the state-by-state legalization process, industry representatives advocated for regulations that allowed aggressive marketing, minimal restrictions on product design, and limited funding for problem gambling treatment services.
Why Your Doctor May Not Have Told You
Gambling disorder is a recognized diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, published by the American Psychiatric Association. But many healthcare providers receive little or no training in recognizing or treating it. Medical school curricula typically include extensive coverage of substance use disorders but limited content on behavioral addictions. As a result, even mental health professionals may not screen for gambling disorder unless a patient specifically raises it.
The symptoms of gambling disorder often overlap with anxiety, depression, and financial stress. If you went to your doctor feeling overwhelmed, unable to sleep, anxious about money, and struggling in your relationships, your provider might have diagnosed and treated your depression or anxiety without ever asking about gambling. The underlying cause remained hidden because no one asked the right questions.
There is also a cultural dimension. Sports betting has been rapidly normalized through saturation advertising and partnerships with mainstream sports. Many people, including healthcare providers, now view sports betting as entertainment rather than as gambling with addiction risk. Your doctor may not have considered that the sports betting app on your phone could be the source of your escalating mental health crisis because the industry has successfully rebranded gambling as a casual leisure activity.
The lawsuits allege that this normalization was intentional. Court filings claim that the companies invested heavily in marketing designed to make sports betting seem fun, social, and harmless, while minimizing messaging about addiction risk. The complaints allege that responsible gaming warnings, when present, were brief, generic, and easy to overlook—similar to the way alcohol advertising includes pro forma warnings that do not seriously convey risk.
Public health infrastructure for gambling harm is also underfunded. Unlike substance abuse treatment, which has a network of public and private resources built over decades, gambling disorder treatment is available at relatively few specialized centers. Many states that legalized sports betting did not allocate sufficient funding for problem gambling services, even as tax revenue from sports betting grew into hundreds of millions of dollars. The lawsuits allege that the industry lobbied for regulatory frameworks that directed minimal resources to harm prevention and treatment.
Additionally, the rapid pace of sports betting legalization meant that it spread faster than research, clinical knowledge, and public health infrastructure could keep up. The first legal mobile sports bets outside of Nevada were placed in 2018. Within five years, mobile sports betting was legal in more than thirty states. Millions of people gained access to these apps before the medical community fully understood the scope of harm they could cause.
Your doctor also may not have told you because you did not tell your doctor. Shame and secrecy are core features of gambling disorder. People hide their gambling from family, friends, and healthcare providers because acknowledging the problem feels like admitting a personal failure. By the time you might have been ready to talk about it, the damage was already severe.
Who Is Affected
Gambling disorder can affect anyone, but certain experiences and circumstances appear in the histories of many people who have filed lawsuits or sought help.
You may have started using a sports betting app after it became legal in your state. Perhaps you saw ads during football season or basketball playoffs. Maybe friends were talking about their bets. You downloaded the app, often receiving a generous signup bonus that gave you free bets or matched your initial deposit. The early experience felt fun and low-risk.
Many people who develop gambling disorder describe a period of early wins that created optimism and confidence. You might have won a few bets in your first weeks of using the app, which made you feel like you understood the games, that you had insight or skill. This early success was reinforcing, and it made you want to keep betting.
Over time, you started betting more frequently. You moved beyond betting on your favorite team to betting on games you did not care about. You discovered live in-game betting and found it especially engaging because you could respond to what you were watching in real time. You started checking the app throughout the day. You found yourself thinking about bets while you were supposed to be doing other things.
The amount of money you were betting increased. What started as five or ten dollars per bet grew to fifty, then a hundred, then more. You chased losses, trying to win back what you had lost in previous sessions. You told yourself that the next bet would turn things around. You deposited more money than you had planned to deposit.
You may have used credit cards to fund your betting account. You may have transferred money from savings, from retirement accounts, or from funds that were supposed to pay bills. You may have borrowed from family members or friends using reasons that were not truthful. The financial damage accumulated faster than you realized.
You tried to stop or cut back and found that you could not. You set limits for yourself and then broke them. You told yourself you would take a break and then found yourself opening the app again the next day. You knew it was causing harm, but the compulsion to keep betting was stronger than your rational understanding of the consequences.
People who have filed lawsuits or sought treatment for gambling disorder related to sports betting apps come from all backgrounds. They include young adults who started betting in college, middle-aged professionals who had never gambled before, and older adults who had disposable income and time. They include people who had no prior history of addiction and people who had previously struggled with alcohol, drugs, or other behavioral problems.
You do not need to have lost a specific amount of money to qualify as someone affected by this issue. Gambling disorder is diagnosed based on patterns of behavior and consequences, not dollar amounts. If you experienced an inability to control your betting, if you lied to conceal your gambling, if you jeopardized relationships or financial stability because of gambling, if you chased losses or felt preoccupied with gambling, you may meet criteria for gambling disorder regardless of the total dollars involved.
The lawsuits include plaintiffs who lost thousands of dollars and plaintiffs who lost hundreds of thousands. The common thread is not the amount but the experience: a rapid progression from casual use to compulsive behavior, devastating consequences despite attempts to stop, and the use of an app designed to maximize engagement without adequate safeguards against harm.
Where Things Stand
Litigation against DraftKings, FanDuel, and BetMGM is ongoing in multiple jurisdictions. Cases have been filed in state and federal courts, with plaintiffs alleging negligence, design defect, failure to warn, unfair and deceptive trade practices, and other claims depending on the jurisdiction and specific facts.
Some lawsuits are proceeding as individual cases, while others seek class action status on behalf of groups of similarly situated users. The legal theories vary, but many cases focus on allegations that the companies designed inherently addictive products, failed to adequately warn users of addiction risk, and failed to implement sufficient safeguards to protect vulnerable users.
As of early 2024, no major settlements or trial verdicts have been publicly reported in these cases, though litigation is at various stages. Some cases are in early motion practice, with defendants filing motions to dismiss or to compel arbitration based on terms of service agreements. Other cases have progressed to discovery, where plaintiffs are seeking internal company documents related to product design, user data, and corporate knowledge of addiction risk.
The legal landscape is complicated by mandatory arbitration clauses in the terms of service agreements that users accept when they create accounts. Many defendants have argued that users must pursue claims in private arbitration rather than in court. Courts have reached different conclusions on the enforceability of these clauses depending on jurisdiction and specific contract language. Some plaintiffs have succeeded in arguing that the arbitration clauses are unconscionable or that certain claims fall outside the scope of the arbitration agreement.
Regulatory action has also begun to emerge. Some state attorneys general have opened investigations into sports betting advertising and responsible gaming practices. In 2023, several states entered into settlements with sports betting companies related to allegations of marketing to underage users or placing ads near schools. These regulatory settlements typically involve financial penalties and commitments to change certain practices, but they do not provide compensation to individual users harmed by gambling disorder.
The timeline for resolution of pending cases is uncertain. Complex product liability and consumer protection litigation often takes years to resolve. Discovery can be protracted, especially when plaintiffs seek extensive internal documents and data from defendants. If cases are not dismissed or settled, they may proceed to trial, which could provide the first jury verdicts on whether sports betting companies should be held liable for gambling disorder harm.
Attorneys representing plaintiffs in these cases have drawn comparisons to litigation against social media companies for mental health harms and against opioid manufacturers for addiction. Those analogies suggest that the legal theories being tested in sports betting litigation may be novel and that outcomes could set precedents for how courts treat behavioral addiction claims related to digital products.
People who believe they have been harmed by sports betting apps and are considering legal action should be aware that statutes of limitations vary by state and by type of claim. These time limits can be short, sometimes as brief as one or two years from the date of injury or from when you discovered the connection between the app and your harm. Consulting with an attorney can clarify whether you have a viable claim and whether the deadline for filing has passed.
What You Need To Know Now
What happened to you was not a personal failing. The apps you used were designed by teams of engineers, data scientists, and behavioral psychologists with the goal of maximizing your engagement. The features that made the apps feel exciting and hard to put down—the instant bets, the live action, the notifications, the bonuses—were built that way on purpose, based on research into what makes digital products habit-forming.
The lawsuits allege that the companies knew or should have known that these design choices would cause addiction in a predictable percentage of users. They allege that the companies had access to research demonstrating the risks. They allege that internal data showed patterns of heavy use and harm. And they allege that business decisions were made to prioritize growth and revenue over user safety.
You were not gambling in a vacuum. You were using a product designed to be addictive, marketed ubiquitously, and deployed with minimal regulatory oversight during a narrow window of rapid state-by-state legalization. The outcomes were not evenly distributed. While some people used the apps casually without harm, others, like you, experienced devastating consequences. The lawsuits argue that this distribution of harm was foreseeable and that the companies failed in their duty to prevent it.
The shame you feel is real, but it is not justified. You are not responsible for the fact that the product was designed the way it was. You are not responsible for the business decisions that prioritized engagement metrics over safety. You responded to a product that was engineered to produce compulsive behavior in users like you, and the science shows that once gambling disorder takes hold, willpower alone is often not enough to stop it.
What happened to you happened to many others. You are not alone. And the legal system is beginning to examine whether the companies that built these products should be held accountable for the harm they have caused. That process will take time, but it is based on a simple principle: companies should not be allowed to profit from products they know are addictive and harmful without warning users, protecting vulnerable people, and taking responsibility for the consequences.
