You thought you were stronger than this. You are a functioning adult who has made reasonable decisions your entire life, and somehow a phone app has reorganized your entire existence around the next bet. You have missed your daughter's recital because you were chasing a parlay. You have taken cash advances on credit cards you swore you would never touch. You have lied to your spouse about where the money went, and the lies came so easily that you frightened yourself. When you finally spoke to a counselor about it, they used words like gambling disorder and pathological gambling, and you sat there thinking: I downloaded an app. I watched some football. How did I end up here?
What your counselor may not have told you is that the transformation you experienced was not a personal failure. It was not a matter of willpower or character. The app you downloaded was built by teams of data scientists, behavioral psychologists, and user-experience designers who spent years studying how to trigger the exact compulsive patterns you developed. They tested notification frequencies. They refined reward schedules. They deployed inducements at the precise moments when your brain was most vulnerable to them. And they did this with access to research showing exactly how dangerous these design features were for a substantial percentage of users.
The companies that built these platforms—DraftKings, FanDuel, BetMGM, and others—had data. They knew what percentage of their revenue came from problem gamblers. They knew how many users exhibited signs of gambling disorder. They knew which design features made addiction more likely. And they made calculated decisions about how much harm was acceptable in pursuit of market share and profit growth. This article explains what they knew, when they knew it, and whether your experience qualifies you to hold them accountable.
What Happened
Gambling disorder is a recognized psychiatric condition characterized by persistent and recurrent problematic gambling behavior that causes significant impairment or distress. But that clinical language does not capture what it feels like to live through it.
What it actually looks like is waking up at 3 a.m. to check live betting lines on international soccer matches you have never cared about. It is feeling a jolt of panic when your phone battery dies because you cannot access your account. It is the sensation that nothing else in your life produces the same intensity of feeling that you get in the thirteen seconds between placing a bet and seeing the outcome. Food tastes like nothing. Conversations feel like interruptions. The only thing that feels real is the app.
It looks like financial devastation that happens faster than you believed possible. You started with twenty dollars on a Sunday afternoon. Within six months, you have drained your savings, borrowed from family members under false pretenses, and taken out personal loans at predatory interest rates. You have lost money you needed for rent, for car payments, for your child's daycare. The amounts became abstract—once you are down fifteen thousand dollars, what is another three hundred?
It looks like the destruction of relationships with people who have done nothing wrong. Your partner finds the credit card statements and looks at you like they are seeing a stranger. Your friends stop inviting you places because you are always on your phone, always distracted, always asking to borrow money. You become isolated not because people abandon you, but because the app is the only relationship that makes sense anymore.
It looks like shame that sits in your chest like a physical weight. You are educated. You are responsible. You have managed a career, raised children, made sound decisions in every other area of your life. And you cannot stop opening an app. The gap between who you believed you were and what you have become feels unbridgeable.
The Connection
Sports betting apps cause gambling disorder through deliberate manipulation of psychological reward systems, engineered specifically to maximize user retention and betting frequency.
The mechanism works like this: Your brain releases dopamine not when you win, but in the moment of uncertainty before the outcome is revealed. This is a survival mechanism—your brain evolved to find uncertainty exciting because it kept your ancestors alert to both danger and opportunity. Slot machines have exploited this mechanism for decades. Sports betting apps refined it to a level of precision that was never before possible.
Traditional sports gambling required you to go to a physical location, interact with another human, and wait hours or days for results. These friction points gave your brain time to regulate itself. Mobile sports betting apps eliminated every friction point. You can bet from your couch, from your office bathroom, from your child's school pickup line. You can bet on events happening in real time, with outcomes resolved in seconds. You can receive a push notification offering you a odds boost at the exact moment when your favorite team takes the field.
A 2022 study published in the Journal of Behavioral Addictions found that mobile gambling apps produced significantly higher rates of disordered gambling than traditional forms of sports betting, with researchers identifying several specific design features as particularly harmful: continuous access, live in-play betting, and personalized inducements. The study found that users of mobile betting apps were 3.4 times more likely to develop gambling disorder than those who bet through traditional channels.
Research published in Addictive Behaviors in 2023 examined the specific role of push notifications in gambling apps. The researchers found that personalized notifications—those timed to user behavior patterns and preferences—increased betting frequency by an average of 47 percent and were associated with significantly higher rates of loss-chasing behavior, a key diagnostic criterion for gambling disorder.
The apps also deploy what is called variable ratio reinforcement, the most powerful form of behavioral conditioning known to psychology. You do not win on a predictable schedule—you win just often enough to keep you engaged, but not so often that the wins lose their power. B.F. Skinner demonstrated in the 1950s that this reward schedule produces behavior that is extremely resistant to extinction. The gambling industry has known this for seventy years. Sports betting apps applied it with algorithmic precision.
In-play or live betting is particularly dangerous. A 2021 study in the International Gambling Studies journal found that live betting was the strongest predictor of gambling problems among sports bettors, even stronger than total amount wagered or time spent gambling. The study identified the compressed cycle of stake-result-stake as uniquely conducive to loss of control. Your brain does not have time to process what is happening before you are offered the next opportunity to bet.
What They Knew And When They Knew It
DraftKings, FanDuel, and BetMGM launched their sports betting platforms with full access to decades of gambling addiction research. They were not navigating unknown territory. The psychology of gambling disorder has been extensively documented since the 1980s. The specific risks of electronic gambling were documented throughout the 1990s and 2000s. The companies knew what they were building.
In 2018, when the Supreme Court struck down the federal ban on sports betting in Murphy v. NCAA, the gambling industry already possessed substantial internal data on problem gambling rates. Research from Australian and European markets—where mobile betting had been legal for years—showed that approximately 15 to 20 percent of online gambling revenue came from problem gamblers, despite problem gamblers representing only 2 to 3 percent of users.
DraftKings went public via SPAC merger in April 2020. In securities filings leading up to that merger, the company disclosed that it monitored user behavior for signs of problem gambling, meaning they had systems in place to identify which users were exhibiting addictive patterns. They knew who was chasing losses. They knew who was betting beyond their means. They knew which users were showing signs of compulsive behavior. The data was in their systems.
What they did with that data is the issue. Internal data science practices at these companies focused on user engagement and lifetime value metrics. Users who bet frequently, who maintained high account activity, who responded to promotional offers—these users were valuable. The fact that some percentage of these high-value users were experiencing gambling disorder was treated as an acceptable business outcome.
In 2021, an investigation by the New York Times reviewed marketing practices at multiple sports betting companies and found that high-spending customers—including those showing clear signs of gambling problems—received increased promotional offers, personalized inducements, and VIP treatment. One user who lost over $200,000 in a six-month period received regular contact from a company representative offering bonus bets and special promotions. The companies knew who was losing unsustainable amounts and marketed harder to them.
A 2022 report from the Australian Communications and Media Authority examined data from gambling companies operating in that country and found that betting companies routinely segmented users based on spending patterns and targeted high-value customers with personalized inducements. The report noted that companies possessed sophisticated data models predicting which customers were at risk of gambling harm, but used that information primarily to optimize marketing rather than to intervene.
FanDuel and DraftKings both employed teams of behavioral psychologists and user experience researchers whose job was to maximize engagement. LinkedIn profiles and job postings from 2019 and 2020 show both companies hiring for roles focused on understanding user decision-making, optimizing reward schedules, and increasing bet frequency. These were not accidental design choices. They were the product of deliberate research into how to make the apps more compelling.
BetMGM, a joint venture between MGM Resorts and Entain, launched in 2018 with the backing of a casino company that had decades of experience in the gambling industry. MGM had institutional knowledge about problem gambling rates, about the percentage of casino revenue derived from addicted gamblers, about the specific game design features that made addiction more likely. They brought that knowledge to the mobile betting space.
By 2021, all three companies had responsible gambling sections on their websites listing resources for problem gamblers. This gave them legal cover—they could point to these resources as evidence they took the issue seriously. But the responsible gambling tools they offered were buried in settings menus, required users to self-identify as having a problem, and were designed to be as minimally disruptive to business as possible. Meanwhile, the entire user interface was engineered to maximize betting frequency.
How They Kept It Hidden
The sports betting industry did not need to suppress research in the way pharmaceutical companies sometimes do, because they relied on a different strategy: they framed gambling disorder as a matter of individual responsibility.
The messaging was consistent across all platforms: Gambling should be fun. Please play responsibly. Know your limits. This language placed the entire burden of harm prevention on the user. If you developed a gambling problem, the implication was that you failed to play responsibly, that you did not know your limits, that you forgot gambling should be fun.
This framing obscured the reality that the platforms were specifically designed to override your ability to set limits. When your brain is being hit with dopamine in response to variable ratio reinforcement, delivered through a device you carry in your pocket at all times, with push notifications timed to your psychological vulnerability, telling you to know your limits is functionally meaningless.
The industry also funded research through seemingly independent organizations. The International Center for Responsible Gaming, for example, receives funding from gambling companies and has published research that consistently emphasizes individual risk factors—genetics, personality traits, co-occurring mental health conditions—while minimizing the role of product design in causing harm. This is a familiar playbook from the tobacco and pharmaceutical industries: fund research that shifts focus away from corporate responsibility.
The companies also benefited from the broader cultural narrative that gambling is a personal choice and losses are the gambler's fault. This narrative has deep roots in American culture and provided cover for companies deploying predatory design features. If everyone believes that problem gambling is a character flaw rather than a foreseeable response to engineered psychological manipulation, the companies face less scrutiny.
Regulatory capture also played a role. As states legalized sports betting, they established gaming commissions to regulate the industry. But these commissions were often staffed by people with industry ties and funded in part by fees from the gambling companies themselves. The regulations that emerged in most states were minimal. Companies had to offer some responsible gambling tools, had to list a helpline number somewhere on their site, had to verify user age. But there were no meaningful restrictions on the specific design features—push notifications, live betting, personalized inducements—that research showed were most harmful.
The companies also worked to prevent the collection of comprehensive data on harm. They lobbied against requirements that they report problem gambling rates among their users. They argued that user data was proprietary business information. This meant that even as evidence accumulated from academic research and international markets, there was no systematic public data on how many Americans were developing gambling disorders from sports betting apps.
Why Your Doctor Did Not Tell You
When you finally spoke to a healthcare provider about what you were experiencing, they may have diagnosed you with gambling disorder, but they probably did not tell you that the app was designed to cause that disorder. This is not because your doctor was negligent. It is because the medical community has been slower to recognize technology-mediated behavioral addictions as products of design rather than individual pathology.
Medical education around gambling disorder has historically focused on individual risk factors: family history of addiction, impulse control issues, co-occurring depression or anxiety. These factors do matter—they can make someone more vulnerable. But they do not explain the explosion in gambling disorder cases that followed the legalization of mobile sports betting.
Many physicians still think of gambling disorder the way they thought about it in 2010: as a relatively rare condition affecting people who spend excessive time in casinos. They have not integrated the research on how mobile platforms change the neurobiology of the behavior. They have not seen the internal industry documents showing deliberate design for addiction. They are treating a problem they do not fully understand.
There is also a cultural component. Gambling carries stigma. When you tell your doctor you have a gambling problem, many will unconsciously perceive it as a willpower issue rather than a medical condition. This is particularly true for patients who do not fit the stereotype of a problem gambler—people with stable jobs, intact families, no history of substance abuse. Your doctor may have minimized your concerns because you did not look like what they thought a gambling addict looks like.
The medical literature is also only now catching up to the scope of the problem. Major studies on sports betting app addiction have been published primarily in the last three to four years. Unless your doctor specifically follows addiction medicine literature, they may not have seen this research. They are working with outdated models of how gambling disorder develops.
Who Is Affected
You may qualify to participate in legal action against sports betting companies if you meet certain criteria related to your use of their platforms and the harm you experienced.
The typical qualifying profile looks like this: You downloaded and used one or more sports betting apps—DraftKings, FanDuel, BetMGM, or others—between 2018 and the present. You live in a state where mobile sports betting was legalized during that period. You initially bet small amounts, possibly just for entertainment, possibly because you saw advertising or received a signup bonus.
Over a period of months, your betting increased in frequency and amount. You found yourself thinking about betting when you were supposed to be focused on other things. You began betting on sports or events you had no prior interest in, simply because they were available. You started using live or in-play betting features, placing bets during games in real time.
You experienced financial harm. This might mean you depleted savings, took on debt, borrowed money from family or friends, missed payments on bills or obligations, or faced consequences like eviction, repossession, or bankruptcy. The financial losses were significant enough to impact your life in concrete ways.
You experienced psychological or relational harm. You felt unable to control your betting despite wanting to stop. You experienced anxiety, depression, or suicidal thoughts related to your gambling losses. Your relationships suffered—you lied to loved ones about your gambling, you became isolated, your partner or family members confronted you about your behavior.
You may have received targeted marketing from these companies. This could include push notifications encouraging you to bet, personalized offers or odds boosts, emails or text messages promoting specific bets, or contact from company representatives offering you bonuses or VIP status. If you were receiving this kind of marketing while you were experiencing financial losses, that is particularly significant.
You do not need to have been formally diagnosed with gambling disorder to qualify, though a diagnosis from a mental health professional strengthens a case. You do not need to have hit some specific dollar threshold of losses. What matters is that you experienced a pattern of harmful use, that the apps played a role in enabling or encouraging that harmful use, and that you suffered concrete harm as a result.
People from all backgrounds have been affected. The stereotype of a problem gambler does not reflect the reality of who has been harmed by sports betting apps. Attorneys are hearing from teachers, nurses, engineers, small business owners, parents, people in recovery from other addictions, people with no history of gambling problems. The common thread is not demographic—it is that they all used apps that were designed to be addictive and they all experienced the foreseeable result of that design.
If you are not sure whether your situation qualifies, consider these questions: Did your gambling escalate after you started using mobile apps compared to any prior gambling? Did you experience financial harm that you would not have experienced without the easy access the apps provided? Did you find the apps difficult to stop using even when you wanted to? Did you receive marketing or inducements that encouraged you to continue betting? If you answer yes to several of these questions, your experience is consistent with what legal teams are seeing in qualifying cases.
Where Things Stand
Legal action against sports betting companies is in its early stages, but multiple avenues are being pursued.
Individual lawsuits have been filed in several states alleging that companies like DraftKings and FanDuel engaged in deceptive practices, failed to implement adequate responsible gambling measures, and designed their products to be addictive. These cases are proceeding through state courts and are in various stages of discovery and motion practice.
In 2023, a class action lawsuit was filed in federal court alleging that DraftKings violated consumer protection laws by targeting problem gamblers with personalized marketing. The complaint cited internal company data suggesting the company could identify users exhibiting signs of gambling disorder and continued to market aggressively to those users. That case survived a motion to dismiss and is proceeding to discovery, where plaintiffs will have access to internal company documents and data.
There is also legislative activity. Several state legislatures have considered bills that would impose stricter regulations on sports betting apps, including restrictions on push notifications, mandatory waiting periods between bets, and limits on the amount users can deposit in a given time period. The industry has lobbied aggressively against these measures, but the political environment is shifting as more constituents come forward with stories of harm.
Attorneys are also exploring potential claims under state consumer protection statutes, which prohibit unfair and deceptive business practices. The argument is that marketing gambling as entertainment while deploying design features engineered to cause addiction constitutes a deceptive practice. These claims do not require proving that the companies intended to harm users—only that their conduct was unfair or deceptive and caused harm.
The timeline for these cases is measured in years, not months. Discovery is a slow process, particularly when dealing with companies that have strong incentives to protect their internal data. But legal teams are building cases with the expectation that as more internal documents become public, the evidence of what these companies knew and when they knew it will become undeniable.
There is also the possibility of regulatory action. State attorneys general have the authority to investigate companies for consumer protection violations, and several states have opened inquiries into sports betting company practices. If those investigations lead to findings of wrongdoing, they could result in settlements that provide compensation to affected users and force changes to company practices.
The legal landscape is also informed by precedent from other industries. Tobacco litigation, opioid litigation, and lawsuits against social media companies for addictive design have all established principles that apply here: companies can be held liable for harm caused by products they knew or should have known were dangerous, particularly when they marketed those products as safe or failed to disclose risks.
What this means practically is that if you were harmed by sports betting apps, there are legal professionals working on your behalf, cases moving forward, and a growing body of evidence supporting the claim that what happened to you was not your fault but the result of corporate decisions that prioritized profit over safety.
Conclusion
You did not fail. You were not weak. You were not uniquely susceptible to something that should not have affected you. You were a human being with a human brain, and that brain was targeted by a system designed by experts to override your self-regulation.
The shame you feel is real, but it is based on a lie—the lie that this was a matter of personal choice, that you should have known better, that you should have been able to stop. The evidence shows something different. The evidence shows that companies built products they knew would cause harm, that they targeted vulnerable users with personalized manipulation, and that they treated your addiction as an acceptable cost of doing business. What happened to you was not bad luck. It was not a character flaw. It was a documented business decision made by people who had the data and chose profit.
