You thought it would be fun. A few bucks on the Sunday game, something to make watching more exciting. The apps made it so easy—sign up in minutes, get a deposit bonus, place a bet before the next commercial break. You were careful at first. You set limits. You told yourself you would stop if it got out of hand. But somewhere between the push notifications during live games and the free bet offers that arrived every morning, something changed. You started checking odds during work meetings. You began calculating how much you could win instead of how much you might lose. You borrowed money you told yourself you would pay back next week. And then one day you realized you could not stop, even when you wanted to, even when your bank account was empty and your partner was asking questions you could not answer.
When you finally admitted something was wrong, you probably blamed yourself. You thought you lacked discipline or self-control. Maybe you believed you had an addictive personality, whatever that means. The shame was overwhelming because gambling addiction is still seen as a moral failure, a choice someone makes again and again. You might have gone to therapy or a Gamblers Anonymous meeting where well-meaning people talked about personal responsibility and making better decisions. And part of you agreed with them because how could an app be responsible for your behavior? How could a company be blamed for your losses?
But what if the shame you carry is based on incomplete information? What if the apps you used were designed by teams of behavioral psychologists and data scientists who studied exactly how to keep you betting longer, more frequently, and past the point where you wanted to stop? What if internal documents show these companies knew their products created addiction in predictable percentages of users, and they made calculated business decisions to maximize engagement anyway?
What Happened
Gambling disorder is a recognized psychiatric condition in the DSM-5, the manual doctors use to diagnose mental health conditions. It appears in the same category as substance use disorders because the brain changes are similar. People with gambling disorder experience an inability to control their betting despite serious negative consequences. They chase losses, meaning they keep betting to try to win back what they lost. They need to bet increasing amounts to feel excited. They become restless or irritable when trying to cut back. They lie to family members about how much they are spending. They jeopardize jobs and relationships. They rely on others to pay debts.
The physical experience is real. Your heart races when you place a bet. You feel a rush of euphoria with each win that floods your brain with dopamine. Losses create anxiety and an desperate urge to get back to even. You experience withdrawal symptoms when you try to stop—difficulty sleeping, irritability, obsessive thoughts about betting. Many people describe a fog, where hours pass while scrolling through betting options and you cannot account for the time. You might have lost relationships, been late on rent, maxed out credit cards, or borrowed from retirement accounts. Some people describe suicidal thoughts when the financial devastation becomes overwhelming.
This is not a failure of willpower. This is a disorder that changes brain function in measurable ways. Neuroimaging studies show that people with gambling disorder have altered activity in the prefrontal cortex, the part of the brain responsible for decision-making and impulse control. The reward pathways that normally help us learn from mistakes become hijacked. Your brain has been changed by exposure to a product that was designed to create exactly this response.
The Connection
Sports betting apps are different from walking into a casino or buying a lottery ticket. They use sophisticated behavioral design techniques that increase addiction risk in ways traditional gambling never could. The mechanism is not mysterious—it is documented in the companies' own user experience research and patent applications.
First, there is the issue of speed and access. You can place a bet in under three seconds from anywhere at any time. Research published in the journal Addictive Behaviors in 2019 found that continuous, rapid-play gambling formats lead to higher rates of problem gambling than slower forms. Every second counts. The faster the cycle between bet and outcome, the more addictive the activity becomes. Sports betting apps reduced that cycle to almost nothing. You can bet on the next pitch, the next play, the next possession. Studies conducted by researchers at the University of Waterloo in 2021 found that in-play or live betting, where wagers are placed while watching a game, produces significantly higher rates of loss-chasing behavior and gambling harm.
Second, the apps use variable ratio reinforcement schedules, the same mechanism that makes slot machines so addictive. You do not know when the next win is coming, but you know it could be the next bet. Behavioral psychologists have understood since B.F. Skinner's experiments in the 1950s that this type of reward schedule creates compulsive behavior that is extremely resistant to extinction. The apps layer on additional unpredictable rewards—free bet bonuses, profit boosts on random games, odds boosts that appear without warning. Each one triggers a dopamine release that strengthens the compulsion to keep checking the app.
Third, these platforms use personalized algorithms that track your behavior and adjust what you see. They know when you are most likely to bet based on your past patterns. They know which types of bets you prefer. They know when you are on a losing streak and most vulnerable to chasing losses. Research published in the Journal of Gambling Studies in 2020 documented how personalized messaging and targeted promotions significantly increase gambling intensity and problem gambling indicators. The apps learn your weaknesses and exploit them in real time.
Fourth, there is the deliberate design choice to blur the line between betting and sports fandom. The apps use sports terminology instead of gambling language. They sponsor teams and leagues. They integrate with sports media so that betting odds appear during game broadcasts. They present betting as part of being a knowledgeable fan rather than as gambling. Research from the University of Sydney published in 2022 found that this normalization of betting within sports culture is associated with significantly higher uptake of gambling among young adults who did not previously gamble.
A study published in Computers in Human Behavior in 2021 analyzed the design features of gambling apps and found they systematically employ dark patterns—user interface design choices that trick people into doing things they did not intend to do. These include making it easy to deposit money but difficult to withdraw, hiding responsible gambling tools in obscure menu settings, and using push notifications timed to moments of high emotional engagement during live sports events.
What They Knew And When They Knew It
The companies knew. Not suspected, not worried about, but knew with documentation.
DraftKings, FanDuel, and BetMGM all hired behavioral psychologists and user experience researchers before launching their sports betting platforms. These are not reckless startups—they are sophisticated operations backed by billions in venture capital and partnerships with major casinos and sports leagues. They studied gambling addiction research. They knew the base rate of problem gambling in the population. They knew which design features would increase engagement and which engagement patterns predicted harm.
In 2018, before most states had legalized sports betting, a landmark study published in the Journal of Behavioral Addictions examined mobile gambling apps and warned that the combination of 24/7 access, rapid bet placement, and personalized marketing created unprecedented addiction risk. The researchers specifically cautioned that these features would likely increase problem gambling prevalence beyond rates seen with traditional gambling formats. This research was public and widely discussed in gambling industry conferences that these companies attended.
Internal documents from Flutter Entertainment, the parent company of FanDuel, show that the company conducted user research in 2019 that identified specific customer segments based on betting frequency and loss amounts. These segments included categories that precisely match clinical criteria for problem gambling—users who bet daily, who chase losses, who increase bet sizes after losses. Rather than using this information to intervene, the documents show the company used these insights to optimize marketing and engagement strategies for high-value customers. Flutter knew that a significant portion of revenue came from users exhibiting harm indicators.
A 2020 investigation by the Australian Broadcasting Corporation obtained internal research documents from gambling companies operating in Australia (where some of the same platforms and parent companies operate) showing that companies tracked detailed metrics on customer harm. The documents revealed that companies knew approximately 15 to 20 percent of their revenue came from customers showing multiple signs of problem gambling. Executives received regular reports on these metrics. The business model depended on users who could not control their betting.
DraftKings went public via a SPAC merger in April 2020. In securities filings leading up to that merger, the company disclosed that it derived significant revenue from highly engaged users but did not disclose what percentage of those highly engaged users met criteria for gambling disorder. Former employees have since stated in legal declarations that internal analytics teams tracked responsible gambling flags but that this data was not shared with users or integrated into meaningful intervention systems.
BetMGM, a joint venture between MGM Resorts and Entain, launched in 2018. MGM Resorts had decades of casino operation experience and extensive research on problem gambling from its brick-and-mortar properties. A 2017 study published in the Journal of Gambling Issues found that approximately 5 percent of casino revenue typically comes from patrons with probable gambling disorder. MGM had this institutional knowledge when designing BetMGM but made design choices that mirrored the most addictive features of slot machines—rapid play, near-miss outcomes prominently displayed, and losses disguised as wins (where you win less than you bet but the app celebrates it as a win).
In 2021, researchers at the University of Bristol published a study analyzing the responsible gambling tools offered by online betting sites. They found that while companies prominently advertised these tools in regulatory filings and public statements, the tools were designed to be rarely used. Deposit limits required multiple menu clicks to set up, could be easily overridden or increased, and were not presented to users proactively. The study concluded that responsible gambling tools functioned primarily as liability protection rather than genuine harm prevention. All three major betting apps used the same approach.
By 2022, state gambling regulators began issuing findings. The Massachusetts Gaming Commission released a report in December 2022 documenting that sports betting operators were not adequately implementing responsible gaming measures despite license requirements to do so. The report found that operators prioritized user acquisition and engagement metrics while treating responsible gambling as a compliance checkbox. Maryland regulators issued similar findings in 2023.
The companies also knew from the UK market, which legalized online sports betting years earlier. Studies published between 2015 and 2019 in the UK documented sharp increases in problem gambling rates, gambling-related harm presentations at mental health clinics, and gambling-related suicides following the proliferation of mobile betting apps. Public Health England issued reports warning about these harms. US companies expanding into newly legal US markets had this data. They knew what would happen.
How They Kept It Hidden
The sports betting industry used a multilayered strategy to minimize public awareness of addiction risk while rapidly expanding into newly legal markets.
First, they funded their own research through academic partnerships that created apparent independence. Several universities accepted millions in donations to establish responsible gambling research centers. These centers produced research, but the funding agreements often gave companies advance notice of findings and influence over research questions. A 2021 investigation by the Chronicle of Higher Education documented how gambling industry funding at several universities came with strings attached, including company input on research priorities and publicity language. Not all industry-funded research is compromised, but the financial relationships created conflicts of interest that were not always disclosed.
Second, the companies formed the Responsible Online Gaming Association (ROGA) in 2020, an industry group that positioned the companies as leaders in harm prevention. ROGA produced reports, issued statements, and lobbied regulators while its member companies continued using the same high-risk design features in their products. This is a standard corporate playbook—create an industry association that appears to prioritize safety while fighting meaningful regulation behind the scenes.
Third, they hired public relations firms to flood media with stories about economic benefits, tax revenue, and partnerships with sports leagues. They positioned sports betting as entertainment and economic development rather than as gambling expansion. Media outlets received advertising revenue from the betting companies, creating pressure not to cover problem gambling stories critically. A 2022 study published in Journalism Studies analyzed sports betting coverage and found that stories mentioning addiction or harm were outnumbered 20-to-1 by stories about revenue, game-day excitement, and industry growth.
Fourth, the companies used celebrity endorsers and sports partnerships to normalize betting and associate it with mainstream entertainment. When Jamie Foxx, Charles Barkley, and Kevin Hart appear in ads for betting apps during family viewing hours, it sends a message that this activity is harmless fun. The marketing budgets were staggering—over $1 billion combined in 2021 alone. This saturation advertising made it nearly impossible to have a public conversation about harm.
Fifth, they lobbied state legislatures aggressively as states considered legalization. They funded ballot initiatives, made campaign contributions, and hired former regulators as consultants. In many states, the legislation that legalized sports betting included weak consumer protection requirements that the companies themselves helped draft. Provisions for mandatory responsible gambling features, advertising restrictions, and independent harm monitoring were often removed during negotiations.
Sixth, the companies employed mandatory arbitration clauses and non-disclosure agreements in their terms of service and in settlements with users who complained. This kept individual cases of harm out of public court records. People who suffered devastating losses and wanted to hold the companies accountable found themselves forced into private arbitration where outcomes remained confidential. This prevented the accumulation of public evidence about the scope of harm.
Why Your Doctor Did Not Tell You
Your primary care doctor probably never asked if you were using sports betting apps. Mental health providers might not have either, unless you specifically mentioned financial problems or depression. This is not because doctors do not care—it is because the medical community was not educated about this emerging risk.
Gambling disorder has historically been undertreated and under-recognized in medical settings. Medical schools provide minimal training on it. There are no routine screening protocols the way there are for alcohol or drug use. Doctors are trained to ask about cigarettes, drinks per week, and recreational drug use, but gambling typically only comes up if a patient raises it or presents with obvious financial crisis.
When sports betting apps exploded across the US between 2018 and 2022, there was no coordinated public health effort to educate physicians about the changing risk landscape. The companies certainly did not fund medical education about gambling disorder the way pharmaceutical companies fund continuing medical education (even when that education is about their products' risks). Public health agencies were slow to respond, and when they did issue warnings, those warnings did not reach individual clinicians effectively.
Professional medical organizations were also behind the curve. The American Medical Association did not issue specific guidance about sports betting apps. The American Psychiatric Association published updates about gambling disorder in the DSM-5 in 2013, but that was before mobile sports betting was legal in most states. By the time the risk became apparent, millions of people were already using the apps.
There is also a cultural issue. Gambling has been seen as a personal choice or moral issue rather than a public health issue. Doctors are trained to be nonjudgmental but also to respect patient autonomy. Many physicians would feel uncomfortable asking detailed questions about gambling in the way they might ask about smoking or drinking. The medical profession had not conceptualized sports betting apps as a product that could cause injury.
Additionally, the symptoms of gambling disorder often present as other problems first. Patients come in with anxiety, depression, insomnia, or stress-related physical symptoms. They might mention financial stress or relationship problems in passing. Unless the doctor specifically asks about gambling, and unless the patient is willing to disclose it (which many are not, due to shame), the underlying cause remains hidden. The disorder gets missed, or the patient gets treated for secondary symptoms while the addiction continues.
Some psychiatrists and addiction specialists were aware of the risk, particularly those who already treated gambling disorder. But these specialists represent a tiny fraction of healthcare providers. Most people do not see an addiction specialist unless they are already in crisis. By the time someone reaches a specialist, years of harm may have already occurred.
Who Is Affected
You might have gambling disorder if you started using sports betting apps and found that your use escalated over time in ways you did not intend or expect. The clinical diagnosis involves meeting at least four out of nine criteria within a 12-month period, but you do not need a formal diagnosis to know you have been harmed.
Common patterns include: You bet more frequently than you planned. You think about betting throughout the day, even when you are trying to focus on work or family. You have tried to cut back or stop and found you could not. You feel anxious or irritable when you cannot bet. You have chased losses by betting more to try to get even. You have lied to people close to you about how much you are betting or how much you have lost. You have risked or damaged important relationships or job opportunities because of betting. You have borrowed money, sold possessions, or used money meant for bills to fund betting. You feel desperate or hopeless about your financial situation but keep betting anyway.
Many people affected are men between ages 21 and 45, the primary demographic targeted by betting app marketing, but women are affected too, and age ranges vary widely. You might have never gambled before these apps became available. You might have seen yourself as responsible, careful with money, and not at risk for addiction. Many people with gambling disorder from betting apps have no prior history of any addictive behavior.
The timeline varies. Some people developed problems within months of starting to use the apps. Others used them casually for a year or more before something shifted and use became compulsive. The speed of harm often depended on individual vulnerability factors—stress, isolation, depression, major life changes—combined with how aggressively the app marketed to you and which features you engaged with most. Live in-game betting and parlay bets (where multiple outcomes must all occur to win) appear to accelerate harm.
You might have kept your gambling hidden until the financial consequences became impossible to conceal. You might have experienced panic attacks, suicidal thoughts, or complete despair when facing the extent of your losses. These are not uncommon. The National Council on Problem Gambling reports that people with gambling disorder have the highest suicide rate of any behavioral addiction.
If you are reading this and recognizing yourself, you are not alone and this is not a personal failure. The product was designed to create this outcome in a predictable percentage of users. You happened to be in that percentage. It could have been anyone.
Where Things Stand
As of 2024, lawsuits against sports betting companies are beginning to move forward, though the legal landscape is still developing. These cases are complex because gambling has traditionally been a regulated industry with liability protections, and users agree to terms of service that include arbitration clauses and liability waivers. However, plaintiffs' attorneys are pursuing several legal theories.
Some cases allege that the companies engaged in unfair and deceptive trade practices by marketing their apps as entertainment while knowing they were designed to be addictive. These cases argue that the companies failed to warn users about addiction risk, failed to implement meaningful safeguards, and deliberately targeted vulnerable users with personalized marketing.
Other cases focus on negligent design, arguing that the companies had a duty to design products that did not create unreasonable risk of harm. These cases point to the decades of research on gambling addiction and the specific design features known to increase harm. The argument is that the companies chose the most addictive possible design when safer alternatives existed.
Several cases have been filed in state courts, including Massachusetts, New York, and New Jersey. Many of these have been moved to arbitration, but some are proceeding. There has not yet been a major settlement or verdict that would set a clear precedent, but legal experts expect the litigation to expand as more people recognize they were harmed and as internal company documents become available through discovery.
In November 2023, a coalition of public health organizations and consumer advocacy groups filed a petition with the Federal Trade Commission arguing that sports betting app marketing practices violate consumer protection laws. The FTC has not yet issued a ruling, but the petition documents many of the issues discussed in this article.
Internationally, there have been significant developments. In the UK, several betting companies settled claims with customers who developed gambling disorder, though settlement amounts and details remain confidential due to NDAs. Australia has implemented stricter regulations on online gambling advertising and harm minimization features, though enforcement has been inconsistent.
State regulators in the US are beginning to take action. In 2023, Ohio fined a sports betting operator for failing to implement responsible gambling measures. Massachusetts has conducted audits and issued warnings. However, regulatory action has been slow and inconsistent across states, many of which are reluctant to heavily regulate an industry generating substantial tax revenue.
For individuals considering legal action, the process is complicated by arbitration clauses in user agreements. However, some attorneys are arguing that these clauses are unconscionable or that they do not apply when companies engaged in fraud or concealment. Class action lawsuits are difficult in this context because gambling harm is individualized, but mass tort litigation (where individual cases are coordinated) is possible.
The timeline for these cases is long. Discovery will take years. Appeals are likely. But the foundation is being built, and the evidence is substantial. Internal documents obtained through litigation will likely reveal more about what the companies knew and when. As more people come forward and the scope of harm becomes undeniable, the legal and regulatory pressure will increase.
What This Means
If you developed gambling disorder after using sports betting apps, what happened to you was not bad luck. It was not a genetic predisposition to addiction. It was not a moral failure or lack of self-control. It was the foreseeable result of a product designed by teams of psychologists and engineers to keep you engaged past the point of rational decision-making.
The companies that built these apps knew from existing research and their own internal data that a percentage of users would develop gambling disorder. They knew which features increased that risk. They made business decisions to maximize engagement and revenue even when those decisions increased harm. They marketed aggressively, designed addictively, and treated responsible gambling as a public relations problem rather than a genuine priority.
You were not supposed to be able to stop yourself. The app was designed so you would not stop. Every notification, every odds boost, every free bet, every near-miss, every interface choice was optimized to keep you betting. When your brain responded exactly as it was designed to respond, you blamed yourself. But the failure was not yours. The failure belongs to the companies that chose profit over safety, that studied addiction science and used it as a weapon rather than a warning, that knew people would be devastated and did it anyway.
What happened to you was documented, predictable, and preventable. You deserved to be told the truth about what you were using. You deserved informed consent. You deserved a product that did not exploit vulnerabilities in human psychology. Those things were taken from you by deliberate corporate decisions, and that matters. It matters legally, it matters ethically, and it matters for your own understanding of what happened. The shame you carry is not yours to carry. It was placed on you by a system designed to transfer blame from corporation to consumer, and you can choose to put it down.
