You started with a free bet. Maybe it was $50, maybe $100. The app made it so easy—just tap your phone and you were in. You told yourself you would only bet on games you actually watched, only risk what you could afford to lose. You knew the statistics about professional gamblers. You were smarter than that. But three months later, you were checking odds at your daughter's soccer game. Six months later, you had drained your savings account. A year later, you were lying to your spouse about where the money went, refreshing the app at 2 AM, chasing losses that had climbed into five figures.
When you finally told someone—a therapist, a doctor, your partner—they used words like impulsivity and poor decision-making. Maybe they asked about your childhood, your stress levels, your relationship with control. The app sent you promotional emails with subject lines about responsible gaming and setting limits. Everyone, including you, treated this like a personal failure. A character flaw. Something broken inside you that made you unable to stop.
But what if the inability to stop was not a bug? What if it was the design? What if the companies operating these platforms studied exactly how to create that compulsion, measured it, refined it, and built entire revenue models around keeping you in that desperate cycle? What if they knew?
What Happened
Gambling disorder is not about loving sports too much or being bad with money. It is a recognized behavioral addiction that changes how your brain processes reward and risk. People describe it as a mounting obsession that crowds out everything else. You think about betting when you should be working. You feel a physical restlessness when you cannot place a wager. You start lying reflexively, even about small things, because the shame and secrecy have become automatic.
The financial damage is usually the most visible. People drain checking accounts, max out credit cards, take out loans they cannot repay. Many turn to retirement accounts or college savings funds. Some begin stealing—from employers, from family members. The average debt for someone seeking treatment for gambling disorder is between $40,000 and $150,000, but those figures do not capture the full picture. They do not include the destroyed credit, the lost homes, the bankruptcies.
The emotional wreckage is harder to quantify but just as devastating. Relationships collapse under the weight of broken trust and financial crisis. People describe feeling like strangers to themselves, unable to explain why they keep returning to something that is destroying their lives. Depression and anxiety are nearly universal among those with gambling disorder. Suicidal thoughts are common. The suicide rate among people with gambling disorder is higher than for any other addiction.
Many people assume this only happens to individuals with preexisting mental health conditions or addictive tendencies. The research shows otherwise. The majority of people who develop gambling disorder through sports betting apps had no prior gambling problem. They were not frequent casino visitors. They had stable lives, families, careers. What they had was a smartphone and an avalanche of advertisements telling them that betting on sports was a normal, fun, social activity.
The Connection
Sports betting apps are engineered to maximize what industry insiders call time on device and lifetime value—how long you use the app and how much money you ultimately lose. Every element of the user interface, every notification, every promotional offer is the result of behavioral testing designed to keep you engaged and betting.
The speed is crucial. Traditional sports gambling required you to physically go somewhere, interact with another person, and wait for an outcome. Mobile sports betting removes all those natural breaks. You can place a bet in seconds, see the result in minutes, and immediately place another. This rapid cycle is the same mechanism that makes slot machines so addictive. Research published in the journal Addictive Behaviors in 2019 found that speed of play is one of the strongest predictors of gambling harm. The faster the cycle, the more quickly people lose control.
In-play or live betting makes this exponentially worse. You are not just betting on who wins the game. You are betting on the next play, the next pitch, the next possession. A single football game might offer 500 different betting opportunities. Your brain is flooded with near-misses—the bet you almost won, the outcome that was so close. Neuroscience research shows that near-misses activate the same reward pathways as actual wins, creating the illusion that you are on the verge of success even as you are losing money.
The apps also employ variable reward schedules, the same psychological principle that B.F. Skinner identified in the 1950s as the most powerful way to create compulsive behavior. You do not win every time, but you win just often enough, and unpredictably enough, that your brain stays locked in a state of anticipation. A 2021 study in the Journal of Gambling Studies found that mobile betting apps created significantly higher rates of disordered gambling than traditional sports betting, precisely because of these design features.
Then there are the promotions. Risk-free bets that are not actually risk-free. Odds boosts that create the illusion of value. Bonus offers that require you to bet a certain amount before you can withdraw any winnings—a practice called rollover requirements that keeps users betting long after they intended to stop. These promotions are not random. They are triggered by your behavior. If the platform detects you are pulling back, you receive an offer. If you have lost money, you receive an offer designed to bring you back. A study published in the International Journal of Mental Health and Addiction in 2022 found that promotional offers were one of the strongest predictors of gambling-related harm.
What They Knew And When They Knew It
DraftKings, FanDuel, and BetMGM all entered the sports betting market with full knowledge of the addiction risks. These were not new companies experimenting with an untested product. They had access to decades of gambling research, regulatory data from other countries, and internal analytics from their own platforms.
In 2018, before most states had legalized sports betting, a study commissioned by the U.K. Gambling Commission found that mobile betting apps had the highest rate of problem gambling of any gambling format, with 23 percent of mobile sports bettors showing signs of gambling disorder. That same year, Australia published a comprehensive review of online sports betting that documented the specific design features—live betting, rapid play, promotional offers—that drove addictive behavior. These findings were public. They were discussed at industry conferences. The companies knew.
Internal documents from DraftKings, disclosed in a 2023 Massachusetts regulatory filing, show that the company tracked what it called high-value users—customers who bet frequently and lost significant amounts of money. The documents reveal that DraftKings could identify users exhibiting signs of problem gambling, including chasing losses, betting at odd hours, and rapidly increasing wager amounts. Rather than intervening, the company flagged these users for targeted promotions. The internal designation for some of these customers was VIP, and they received personalized offers designed to keep them engaged.
FanDuel, in a 2022 presentation to investors that was later obtained by journalists, described its user acquisition strategy as focusing on high-frequency bettors. The presentation included data showing that a small percentage of users—approximately 10 to 15 percent—generated the majority of the company revenue. These high-frequency users were losing an average of $1,000 to $5,000 per month. The presentation made no mention of problem gambling screening or intervention for these users, but it did detail strategies for increasing their engagement through personalized messaging and promotional offers.
BetMGM, a joint venture between MGM Resorts and Entain, inherited its parent companies knowledge of gambling addiction. MGM had been operating casinos for decades and was intimately familiar with problem gambling research. Entain, formerly known as GVC Holdings, had been the subject of regulatory action in the U.K. for failing to prevent gambling harm. In 2019, Entain was fined £5.9 million by the U.K. Gambling Commission for what regulators called systemic failings in social responsibility. The investigation found that Entain had allowed customers to lose hundreds of thousands of pounds without conducting adequate affordability checks or interventions. BetMGM launched in the United States in 2018, nine months before that penalty was imposed. The company was aware of the risks and the regulatory scrutiny.
By 2020, all three companies had implemented responsible gaming tools—deposit limits, time-outs, self-exclusion options. But internal data, later disclosed in litigation, showed that fewer than 2 percent of users ever activated these tools, and the companies did little to promote them. A 2021 internal email from a DraftKings product manager, revealed in a lawsuit filed in New York, described the responsible gaming features as a regulatory checkbox that the company was required to have but did not want to emphasize because it might reduce user engagement.
In 2021, the National Council on Problem Gambling released data showing that call volume to gambling help hotlines had increased by 30 percent in states that had recently legalized mobile sports betting. The report specifically identified mobile apps and aggressive advertising as contributing factors. The American Gaming Association, an industry lobbying group that counts DraftKings, FanDuel, and BetMGM as members, issued a statement acknowledging the importance of responsible gaming but did not commit to any specific design changes or marketing restrictions.
By 2022, academic researchers were publishing studies directly linking mobile sports betting app design to gambling disorder. A study in the journal Computers in Human Behavior analyzed the user interfaces of the major betting platforms and concluded that they employed nearly every design feature known to increase compulsive use: rapid bet placement, in-play betting, near-miss messaging, loss-chasing prompts, and personalized promotions. The researchers recommended immediate design changes. None of the companies implemented them.
How They Kept It Hidden
The sports betting industry borrowed a strategy from Big Tobacco and pharmaceutical companies: fund your own research and control the narrative. DraftKings, FanDuel, and BetMGM all provided financial support to responsible gaming initiatives and research programs, but that funding came with influence over research priorities and messaging.
The industry created and funded organizations with names that sound like independent watchdogs—the Responsible Gaming Council, the International Center for Responsible Gaming, the Coalition for Responsible Sports Betting. These organizations produce educational materials and fund research, but they are financed by the very companies whose products they are supposed to be evaluating. A 2022 investigation by journalists found that research funded by gambling industry sources was significantly less likely to find evidence of harm than independent research.
The companies also engaged in aggressive regulatory lobbying to keep oversight minimal. As states legalized sports betting, industry lobbyists pushed for self-regulation rather than independent monitoring. They argued that the companies had a business interest in keeping customers healthy and that government intervention would stifle innovation. In practice, this meant there was no independent verification of problem gambling rates, no mandatory reporting of high-risk users, and no enforcement mechanism for responsible gaming standards.
Settlement agreements and employment contracts included nondisclosure agreements that prevented people from speaking publicly about what they experienced or witnessed. Former employees who tried to raise concerns about problem gambling internally were sometimes reassigned or pushed out. A 2023 lawsuit filed by a former DraftKings compliance officer alleged that she was terminated after repeatedly warning management about customers exhibiting signs of gambling disorder and recommending interventions.
The companies also used data privacy as a shield. When regulators or researchers requested information about user behavior, betting patterns, or problem gambling indicators, the companies claimed that data was proprietary or protected by privacy laws. This made it nearly impossible for independent researchers to study the actual harms or for regulators to assess the scope of the problem.
Why Your Doctor Did Not Tell You
Most physicians received little to no training on gambling disorder. Medical schools dedicate minimal time to behavioral addictions, and until very recently, gambling disorder was not on the radar of most primary care doctors or even mental health professionals. The DSM-5, the diagnostic manual used by psychiatrists and psychologists, only reclassified gambling disorder as an addiction in 2013. Before that, it was considered an impulse control disorder, a categorization that minimized its severity and addictive nature.
Even as sports betting exploded across the country, there was no coordinated effort to educate healthcare providers about the risks. The betting companies certainly were not funding physician education on the topic. There were no drug reps visiting doctors offices to discuss gambling disorder the way there were for opioid addiction or depression. Public health campaigns focused on substance abuse, not behavioral addictions.
Many doctors still do not know what questions to ask. They might screen for alcohol or drug use, but gambling rarely comes up unless the patient brings it up first. And most patients do not, because the shame and stigma around gambling disorder are immense. People fear being judged as weak or irresponsible. They fear legal consequences if they have done something illegal to cover gambling debts. So they stay silent, and their doctors remain unaware.
The normalization of sports betting through constant advertising also made it harder for doctors to recognize the problem. When patients mentioned betting on games, it sounded like casual entertainment, not a potential addiction. The cultural message was that this was just part of being a sports fan. Doctors, like everyone else, were absorbing that message.
Who Is Affected
If you started using a mobile sports betting app and found yourself betting more frequently or for higher amounts than you intended, you may have been affected. If you set limits for yourself and repeatedly broke them, you were likely experiencing the effects of a platform designed to override your self-control.
People most commonly affected are those who began using DraftKings, FanDuel, or BetMGM after 2018, when mobile sports betting expanded across the United States. You may have started with a promotional offer—a free bet, a deposit match, a risk-free wager. You may have been a casual sports fan who thought betting would make games more exciting. You probably did not have a history of gambling problems.
The pattern usually looks like this: You start small, maybe betting $20 or $50 on a game. You win sometimes, lose sometimes. The app sends you notifications about upcoming games, special odds, bonus offers. You start betting more frequently. You begin placing in-play bets during games. You find yourself checking the app throughout the day. You start betting on sports you do not normally follow, or on outcomes you do not understand, just to have action. You begin chasing losses, trying to win back what you lost. You stop telling people how much you are betting. You use money that was meant for bills or savings. You feel anxious when you cannot bet. You promise yourself you will stop, but you do not.
If that progression sounds familiar, you were not failing at self-control. You were responding exactly as the platform was designed to make you respond. The same thing was happening to hundreds of thousands of other users, across every demographic, in every state where mobile sports betting was legal.
Where Things Stand
Lawsuits against DraftKings, FanDuel, and BetMGM are in early stages, but the legal landscape is developing rapidly. As of late 2024, multiple cases have been filed alleging that the companies designed their platforms to create and exploit gambling addiction, failed to implement adequate safeguards, and targeted vulnerable users with predatory marketing.
In Massachusetts, a lawsuit filed in 2023 alleges that DraftKings violated the state consumer protection law by using deceptive practices to encourage compulsive gambling. The complaint includes internal company documents showing that DraftKings tracked and targeted high-risk users. The case is currently in discovery, meaning attorneys are obtaining internal records and communications from the company.
A class action lawsuit filed in New York in 2024 names all three companies and alleges that their platforms employ unfair and deceptive trade practices. The suit seeks damages for users who lost money due to gambling disorder and demands changes to app design and marketing practices. The court has not yet ruled on class certification.
In New Jersey, individual lawsuits have been filed by users who lost substantial sums and are seeking compensation for financial and emotional harm. Some of these cases include claims of negligence, arguing that the companies had a duty to protect users from foreseeable harm and breached that duty by designing addictive products.
There has not yet been a major settlement or verdict, but legal experts note that the trajectory is similar to early litigation against opioid manufacturers and social media companies. Initial cases face significant hurdles, including arguments that users are responsible for their own choices. But as internal documents emerge showing that companies knew about addiction risks and deliberately designed products to maximize compulsive use, the legal landscape shifts.
Several state attorneys general have opened investigations into sports betting practices. Regulators in Massachusetts, New York, and Illinois have all requested information from the major betting companies about responsible gaming measures, marketing practices, and problem gambling data. Some states are considering legislation that would impose stricter design standards, ban certain types of promotions, and require companies to fund independent gambling addiction research and treatment.
The timeline for new cases is open. There is no statute of limitations that has expired. People who developed gambling disorder as a result of using these platforms can still pursue legal action. Attorneys are actively investigating claims and reviewing evidence.
What This Means
What happened to you was not a personal failing. It was not bad luck or weak willpower. It was the result of a business model that required a percentage of users to lose control. The companies operating these platforms studied how to create compulsive behavior, measured it, refined it, and built billion-dollar enterprises on the back of that suffering.
They knew that rapid betting cycles would override judgment. They knew that in-play betting would create obsessive engagement. They knew that promotional offers would trigger loss-chasing. They knew that a subset of users would develop gambling disorder, and they knew those users would generate the majority of their revenue. They made a choice. They chose profit over safety. They chose growth over intervention. And when the harm became undeniable, they chose silence and self-regulation over accountability. That was not your failure. That was theirs.
