You thought you were placing a bet on a Sunday football game. You thought you were having fun with friends, making the game more interesting, maybe winning some extra cash. You thought you had control. Then somewhere between the first deposit and the morning you woke up realizing you had lost your savings, your marriage, or your ability to stop checking your phone every three minutes, something changed. Your doctor might have used the term gambling disorder. Your family might have used harsher words. But what you felt was simpler and more terrifying: you could not stop, even when you desperately wanted to.
The shame arrived before the diagnosis. You replayed every decision, every bet, every lie you told yourself about being due for a win. You wondered what was wrong with you. Why could other people place a casual bet and walk away while you found yourself betting on sports you did not even watch, at hours you should have been sleeping, with money you did not have? You assumed this was a personal failing, a weakness of character, something broken in your ability to make rational choices. Your doctor may have told you that gambling disorder is a recognized behavioral addiction, that it changes brain chemistry similar to substance addiction, that it is a medical condition. But that clinical language did not answer the question that kept you awake: how did this happen to you?
What your doctor likely did not tell you, because they probably did not know, was that the platform you were using was designed with precision to make this happen. The companies behind the apps on your phone—DraftKings, FanDuel, BetMGM—built their products using behavioral psychology research, addiction science, and internal data tracking which bets triggered the most compulsive behavior. They tested which notification messages generated the most deposits from people who were losing. They measured how quickly they could move someone from casual betting to daily, then hourly, then constant engagement. And they did this while holding internal research and third-party studies showing exactly how their design features increased addiction risk, financial harm, and the destruction of users' lives outside the app.
What Happened
Gambling disorder does not feel like a disorder at first. It feels like excitement, possibility, a hobby that makes watching sports more engaging. The apps make it seamless. You can place a bet in seconds, between plays, during commercial breaks, while standing in line for coffee. The interface is bright and encouraging. Small wins come early and feel significant. Losses are abstracted into account balances rather than cash leaving your hand. There is always another game, another quarter, another bet type you have not tried yet.
Then the pattern shifts. You start betting more frequently, on games you care nothing about, simply to have action. You begin chasing losses, convinced the next bet will recover what you lost. You take bigger risks because the small bets no longer generate the same feeling. You deposit more money than you intended, then more than you can afford. You hide your phone screen from your partner. You check scores obsessively, feeling a physical rush of anxiety until you know the outcome. You lie about where money went. You borrow, you withdraw from retirement accounts, you make bets you know are irrational but cannot stop yourself from placing.
The emotional experience is a cycle of anticipation, brief euphoria or crushing disappointment, shame, and then the overwhelming urge to bet again. Your brain becomes trained to seek that cycle. Normal activities feel flat. You lose interest in things that used to matter. Relationships become obstacles to betting or sources of money to fund betting. You experience withdrawal symptoms when you try to stop: irritability, anxiety, obsessive thoughts about gambling, an almost physical need to place a bet. Some people describe it as a voice that will not quiet, a compulsion that overrides rational thought, a feeling of being trapped inside behavior they can observe but cannot control.
The financial devastation is often total. People lose savings, college funds, retirement accounts. They accumulate credit card debt, take loans from family, drain joint accounts. Some file for bankruptcy. Others lose their homes. The gambling does not stop when the money runs out. People find ways to get more money, ways that create additional harm: loans from dangerous sources, theft, fraud. The shame compounds with each boundary crossed, but the compulsion to bet overrides the shame in the moment, leading to decisions that would have been unthinkable before the disorder took hold.
Relationships fracture under the weight of lies, broken trust, financial betrayal, and the emotional absence of someone whose attention is consumed by betting. Marriages end. Families are torn apart. Friendships dissolve. The isolation deepens the gambling because the app becomes the primary source of emotional stimulation, filling the void left by destroyed relationships. Some people experiencing gambling disorder describe suicidal thoughts, particularly after catastrophic losses or when facing the full scope of damage they have caused. The suicide rate among people with gambling disorder is significantly elevated compared to the general population.
The Connection
Sports betting apps did not invent gambling addiction, but they industrialized it. The connection between these platforms and gambling disorder is not coincidental or simply a risk inherent to gambling. It is the result of specific design choices, tested and refined using data from millions of users, built to maximize engagement, which in the context of gambling means maximizing betting frequency and total amount wagered.
The psychological mechanisms are well documented in scientific literature spanning decades. Variable ratio reinforcement schedules, where rewards come unpredictably, create the strongest behavioral conditioning. This is why slot machines are more addictive than games with predictable outcomes. Sports betting apps employ this same principle with live in-game betting, where outcomes occur continuously and unpredictably throughout a game. A study published in the International Gambling Studies journal in 2019 found that in-play betting was associated with significantly higher rates of gambling problems compared to traditional pre-game betting.
The apps use push notifications timed to moments of psychological vulnerability. Studies on notification design show that messages sent after a loss, framed as an opportunity to recover, generate higher response rates than random notifications. Research published in Computers in Human Behavior in 2020 demonstrated that gambling notifications increased urge to gamble and actual gambling behavior, particularly among people already showing signs of problem gambling. The companies have this same data from their own testing. They know which messages work, meaning they know which messages override rational decision-making and trigger compulsive behavior.
The speed of online betting removes natural friction that previously allowed for reflection. With traditional gambling, you had to physically travel to a casino or bookmaker, handle cash, experience delays between decision and action. Each of these elements created moments where rational thought could intervene. A study in the Journal of Behavioral Addictions in 2018 found that increased gambling speed was directly correlated with loss of control and higher addiction rates. Sports betting apps eliminated every barrier. Bets are placed in seconds. Money is abstracted into account balances. You can gamble from bed, from work, from your child's soccer game. The constant availability means the behavior can be reinforced hundreds of times per day, accelerating the conditioning process that creates addiction.
The apps also provide data-driven personalization. They track which bet types each user prefers, which messages they respond to, when they are most likely to deposit money, how much they can lose before they stop using the app. This allows the platform to optimize for each individual user's path to maximum betting. A 2021 study in the journal Addiction found that personalized gambling features were associated with higher rates of gambling problems and that users often did not recognize these features as risk factors. The personalization feels like customer service, but it functions as individually targeted exploitation of each user's specific behavioral patterns.
Bonus structures and promotions are designed using principles from addiction research. Free bets, deposit matches, and risk-free bet promotions get users to place bets they would not otherwise place and to continue betting through losing periods. These promotions are heavily concentrated during user acquisition and during periods when a user has stopped betting, functioning as relapse triggers. Research published in the Journal of Gambling Studies in 2020 found that promotional offers were significant predictors of gambling harm and that users exposed to more promotions showed more signs of disordered gambling.
What They Knew And When They Knew It
The companies knew about gambling addiction risk before launching their products because the scientific literature was already clear and because online gambling had already produced addiction data from other markets. The United Kingdom legalized online gambling in 2005, and within years, gambling disorder rates increased significantly. Studies from the UK Gambling Commission documented rising addiction rates, financial harm, and suicide risk associated with online gambling throughout the 2010s. When DraftKings, FanDuel, and BetMGM designed their apps for the US market, this data was available and known to the industry.
In 2018, the Supreme Court struck down the federal sports betting ban, opening US markets. The companies launched their apps immediately, despite knowing that no adequate responsible gambling infrastructure existed in the US. Internal presentations from DraftKings in 2018 and 2019, disclosed in regulatory filings, show company executives discussing customer lifetime value metrics, retention strategies, and engagement optimization. These documents focus on maximizing revenue per user with minimal discussion of addiction risk or harm reduction. The companies knew their business model depended on a small percentage of users who bet frequently and in large amounts, which is the exact profile of someone with gambling disorder.
FanDuel commissioned research in 2019 through a third-party firm studying responsible gambling tools. The research found that self-exclusion tools were difficult to locate in the app, that deposit limits could be easily increased, and that users showing signs of problem gambling received the same promotional messages as recreational users. Despite these findings, the app design remained largely unchanged. The research was not published publicly. It was disclosed years later through legal discovery in lawsuits filed by states attorneys general investigating the companies marketing and design practices.
BetMGM parent company MGM Resorts had decades of data from casino operations showing addiction patterns, warning signs, and the percentage of revenue derived from problem gamblers. Industry estimates, confirmed by multiple studies including research published in the Journal of Gambling Issues in 2014, show that 40 to 60 percent of gambling revenue comes from people with gambling disorder. The companies built their business models around this reality. When MGM entered the online sports betting market, they brought this knowledge with them. Internal training documents from 2020, later disclosed in litigation, showed customer service representatives were instructed to encourage continued play and not to suggest users take breaks or reduce betting, even when users expressed concern about their own behavior.
In 2020, during the pandemic, all three companies saw massive user growth as people were confined to homes with limited entertainment options. Internal data from this period, referenced in investor calls and later in legal filings, showed that average bets per user increased, session lengths increased, and the percentage of users betting daily increased. The companies characterized this as successful growth. They did not implement additional safeguards despite knowing that increased frequency and duration were markers of developing addiction. A study published in the International Journal of Mental Health and Addiction in 2021 documented significant increases in gambling disorder rates during pandemic lockdowns, with online gambling as the primary driver.
By 2021, state regulators in multiple jurisdictions were receiving complaints about gambling harm, underage gambling, and deceptive marketing. Massachusetts Gaming Commission hearings in 2022 included testimony about sports betting apps failing to prevent problem gambling, targeting people who had self-excluded, and using predatory promotional tactics. Internal emails from DraftKings, disclosed during these hearings, showed marketing executives discussing how to maximize promotional spending to acquire users who would become high-value, meaning high-frequency, bettors. The correlation between high-frequency betting and gambling disorder was not mentioned in these emails, but it did not need to be. The research connecting those two data points was already well established in scientific literature the companies had access to.
In 2022, the National Council on Problem Gambling released data showing that calls to gambling help hotlines had increased by over 30 percent since 2018, with the majority of new callers reporting problems with online sports betting specifically. The companies responded with public statements about responsible gambling commitments, but internal documents showed minimal budget allocation to responsible gambling programs compared to marketing spend. DraftKings spent an estimated 1 billion dollars on advertising in 2022 while allocating approximately 5 million dollars to responsible gambling initiatives, a ratio of 200 to 1. The companies knew the scale of harm they were generating because they tracked user behavior data that clearly showed addiction patterns, yet they chose to invest in growth rather than safety.
How They Kept It Hidden
The companies did not hide the existence of gambling addiction, which would be impossible, but they successfully obscured the connection between their specific design features and addiction risk. They did this through strategic responsibility framing, funding research that supported their interests, lobbying for favorable regulations, and using legal settlements to silence victims.
The primary strategy was positioning gambling disorder as a pre-existing condition that certain people bring to gambling, rather than a condition that gambling products create. This framing appeared in company responsible gambling messaging, in statements to regulators, and in funded research. By characterizing addiction as a user problem rather than a design problem, the companies shifted responsibility to individuals. They promoted responsible gambling tools like deposit limits and self-exclusion while designing the core product to maximize the addictive engagement that these tools were supposedly meant to limit. This created a legal shield. When sued, the companies pointed to the existence of responsible gambling features, arguing they had provided tools and that user harm resulted from personal choice.
The companies funded academic research through grants and partnerships with universities. Much of this research focused on topics useful to the industry, such as studies comparing online gambling favorably to casino gambling, or research validating the effectiveness of minimal responsible gambling interventions. Research that might reveal harm was not funded. This created a distorted research landscape where industry-friendly studies were plentiful and well-funded while independent critical research struggled for resources. A 2020 analysis published in the journal Addiction Research and Theory found that gambling industry-funded studies were significantly more likely to produce findings favorable to the industry and that funding sources were often not transparently disclosed.
The companies engaged in extensive regulatory lobbying as states legalized sports betting. They advocated for regulations that maximized market access while minimizing harm reduction requirements. They opposed mandatory limits on promotional offers, fought against restrictions on in-game betting, and successfully lobbied against requirements for prominent display of responsible gambling tools. In state after state, the regulatory frameworks that emerged were shaped significantly by industry input, resulting in weak consumer protections. Documents from state legislative proceedings show industry lobbyists providing draft language for gambling laws, language that often excluded safeguards recommended by public health experts.
Legal settlements with users who sued for gambling-related harm typically included non-disclosure agreements. People who lost everything and sued the companies were offered settlements that came with the condition that they never speak publicly about their experience or the evidence they uncovered in discovery. This prevented the public from learning what internal documents revealed about company knowledge and intent. It kept each victim isolated, unaware that their experience was part of a pattern, unable to warn others.
The companies also employed strategic corporate structure to limit liability. The brands operate through complex networks of parent companies, subsidiaries, and licensing arrangements. This makes it difficult to assign clear legal responsibility and allows companies to argue that different corporate entities handle different functions, obscuring who made which decisions about product design and risk management.
Why Your Doctor Did Not Tell You
Your doctor did not warn you about gambling disorder risk from sports betting apps because physicians received no training on this issue, no alerts from public health authorities, and no information from the companies. Unlike pharmaceutical products, which come with FDA-mandated warnings and provider education, gambling apps launched with no medical community engagement.
Gambling disorder is recognized in the DSM-5, the diagnostic manual physicians use, but it is categorized with substance use disorders and most physicians receive minimal training on behavioral addictions during medical school. A survey published in the Journal of General Internal Medicine in 2021 found that fewer than 15 percent of primary care physicians felt competent to screen for gambling disorder, and most had never asked patients about gambling behavior.
There was no public health campaign when sports betting apps launched. The CDC did not issue guidance. The Surgeon General did not release warnings. State health departments did not educate providers. This stood in stark contrast to responses to other addiction risks, where public health infrastructure typically moves quickly to inform medical providers about emerging threats. The difference was lobbying power and the framing of gambling as entertainment rather than a health risk.
Even if your doctor suspected gambling disorder, treatment resources were scarce. Gambling addiction treatment is not widely covered by insurance. Specialized treatment programs are limited. Most addiction treatment centers focus on substances, and therapists trained in gambling disorder treatment are rare outside major metropolitan areas. Your doctor may have recognized the problem but had nowhere to refer you, which creates a disincentive to screen for a condition they cannot effectively treat.
The companies provided no information to the medical community. They did not fund physician education. They did not develop screening tools for healthcare settings. They did not partner with medical associations to raise awareness. This was a choice. The tobacco industry, despite its decades of deception, eventually participated in provider education about smoking risks. The sports betting industry made no comparable effort because physician awareness of addiction risk would have threatened user growth.
Who Is Affected
If you used DraftKings, FanDuel, or BetMGM and developed gambling disorder, you are not alone, and your experience fits a clear pattern. The question is not whether you were uniquely vulnerable, but whether you were exposed to a product designed to exploit normal human psychology in ways that create addiction.
You may be affected if you started using sports betting apps casually and found your usage increasing over time until it became daily or multiple times per day. If you began betting larger amounts than you initially intended or could afford. If you chased losses, placing bets to recover money you lost in previous bets. If you felt unable to stop or cut back despite wanting to. If you hid your gambling from family or lied about how much you were betting. If gambling caused financial problems, relationship damage, problems at work, or emotional distress including anxiety, depression, or thoughts of suicide.
The timing matters. If you began using these apps after 2018, when mobile sports betting launched in US states following the Supreme Court decision, you were exposed to products designed with years of addiction data and behavioral psychology research. You were not experimenting with a new technology of unknown risk. You were using a product built with knowledge of how to maximize addictive engagement.
The diagnostic criteria for gambling disorder, as defined in the DSM-5, include needing to gamble with increasing amounts to achieve desired excitement, restlessness or irritability when attempting to cut down, repeated unsuccessful efforts to control or stop gambling, being preoccupied with gambling, gambling when feeling distressed, chasing losses, lying to conceal gambling, jeopardizing relationships or opportunities because of gambling, and relying on others to provide money to relieve desperate financial situations caused by gambling. If you experienced four or more of these within a twelve month period, you meet the clinical threshold for gambling disorder.
But the clinical criteria do not capture the full scope of who was harmed. Some people experienced significant financial loss and relationship damage without meeting the full diagnostic criteria. Some recognized the problem early and stopped before reaching the clinical threshold but still suffered consequences. The companies caused a spectrum of harm, and people at every point on that spectrum were impacted by design choices made to prioritize engagement over safety.
Young men were disproportionately targeted and affected. Marketing was heavily concentrated during sports programming that skews young and male. Promotional partnerships with sports leagues, teams, and athletes created an environment where betting was normalized as part of sports fandom. Research published in the Journal of Gambling Studies in 2022 found that men aged 21 to 35 showed the highest rates of sports betting participation and the steepest increases in gambling disorder symptoms after app-based sports betting became available.
People with previous substance use disorders were at elevated risk, though most did not know this. The companies did not screen for addiction history or provide warnings to this population. Studies show significant overlap between substance use disorders and gambling disorder, with shared neurological mechanisms. A 2019 study in the journal Drug and Alcohol Dependence found that people in recovery from substance use disorders were highly vulnerable to gambling addiction, yet this population received targeted marketing from gambling companies with no acknowledgment of the risk.
Where Things Stand
Litigation against DraftKings, FanDuel, and BetMGM is expanding but remains in relatively early stages. The legal landscape includes individual lawsuits, potential class actions, and regulatory enforcement actions at the state level. This is not like the opioid litigation, where thousands of cases were consolidated and massive settlements were reached. The gambling litigation is more fragmented, with different legal theories being tested in different jurisdictions.
Individual lawsuits have been filed in multiple states by people who developed gambling disorder and suffered financial and personal harm. These cases typically allege negligent design, failure to warn, deceptive marketing, and violation of state consumer protection laws. Some cases include claims that the apps violated state laws against predatory lending by encouraging users to deposit funds they could not afford to lose. Many of these cases are in early motion practice, with companies fighting to dismiss claims before discovery.
The legal challenges are significant. Gambling is a licensed, legal activity, which means companies argue they cannot be liable for offering a legal product. They point to responsible gambling tools and argue that users made choices and must bear responsibility for outcomes. They cite user agreements that include arbitration clauses and liability waivers. These are substantial defenses, but they are not insurmountable. Tobacco and pharmaceutical companies also sold legal products and still faced successful litigation when evidence showed they concealed risks and designed products to be addictive.
The key legal question is whether the companies can be held liable not merely for offering gambling, but for designing gambling products in ways they knew would cause addiction and for failing to warn users of those specific risks. This requires plaintiffs to obtain internal documents showing what the companies knew, what research they conducted or possessed, and what design decisions they made with that knowledge. Some of these documents have emerged through state regulatory proceedings. More will likely emerge through discovery in lawsuits that survive motions to dismiss.
Several states have initiated regulatory investigations. Massachusetts, New York, and Illinois have all opened inquiries into sports betting company practices, focusing on marketing to vulnerable populations, adequacy of responsible gambling tools, and whether companies violated state consumer protection laws. These investigations can result in fines, operational restrictions, or license revocation. They also generate documentary records that can be useful in private litigation.
There has been one notable settlement to date that received public attention. In 2023, a lawsuit filed in federal court in Massachusetts by a user who lost over 600,000 dollars settled for an undisclosed amount before reaching discovery. The terms were confidential, but the case established that courts would allow these claims to proceed past initial dismissal motions, which encouraged additional filings.
Class action litigation faces significant hurdles. Gambling losses and addiction experiences vary widely among users, which makes it difficult to certify a class with common injuries. Some legal experts predict that mass tort approaches, similar to those used in pharmaceutical litigation, may be more successful than traditional class actions. This would involve many individual cases with common questions of fact and law, potentially coordinated in multidistrict litigation if enough federal cases are filed.
The timeline for resolution is uncertain. If the litigation follows patterns from other mass tort cases, it could be years before substantial settlements or trial verdicts occur. Early cases that reach trial will be critical. Plaintiffs victories would create settlement pressure. Defense victories would embolden companies to fight rather than settle. The next two to three years will likely determine which direction this litigation moves.
Legislative action is also possible. Some state legislatures are considering laws that would impose stricter design requirements on gambling apps, mandate more prominent warnings, restrict promotional offers, or create a private right of action for users harmed by violations of responsible gambling laws. The industry is fighting these efforts through lobbying, but public awareness of gambling harm is increasing, which may shift the political calculation.
What Happened to You Was Not an Accident
You did not fail. You did not lack willpower or discipline or intelligence. You were not uniquely weak or flawed. What happened to you was the result of a product designed by teams of engineers, data scientists, and behavioral psychologists who tested thousands of variations to find the combination of features that would keep you engaged, which in the context of gambling means the combination that would keep you betting even when you wanted to stop.
The shame you feel is part of how the system works. If you blame yourself, you do not blame the company. If you see this as a personal failing, you do not recognize it as a design outcome. The companies benefit from your shame because shame keeps you isolated and silent. But the documented evidence shows that your experience was not random bad luck or personal weakness. It was a predictable result of known design features, tested on millions of users, refined based on data showing which approaches generated the most compulsive behavior. You responded the way human brains are wired to respond to variable rewards, constant availability, and personalized targeting. The fact that you developed gambling disorder does not mean something was wrong with you. It means the product worked exactly as it was designed to work.
The path forward is not about assigning blame to yourself or waiting for companies to accept responsibility they have spent millions to avoid. It is about seeing clearly what happened, understanding that you were harmed by documented business decisions made by people who knew the likely outcomes, and recognizing that your experience matters. What you know now about how these products work, what these companies knew, and how many others have been harmed in the same ways, that knowledge is the beginning of something different than shame. It is the foundation for holding systems accountable and for understanding that when corporations choose profit over safety, the harm that results is not the fault of the people who trusted that the product was safe to use.
