You remember the exact moment you realized something was wrong. Maybe it was when you checked your bank account and saw the overdraft notices piling up. Maybe it was your partner asking about the missing mortgage payment, or the night you stayed up until 3 AM chasing losses on a Tuesday. You told yourself you were just having fun, that you had it under control, that next week would be different. But every Sunday you promised yourself you would stop, and every Monday the app was open again before lunch.
When you finally talked to someone about it—a therapist, a counselor at Gamblers Anonymous, maybe a doctor—they explained that what you were experiencing was not a moral failure or a lack of willpower. It was a gambling disorder, a recognized mental health condition that affects your brain in measurable, physical ways. You felt relief at first, knowing there was a name for what was happening. But then came the harder question: how did this happen to you? You never had a problem before. You never even went to casinos. You just downloaded an app.
What you were not told, what your doctor likely did not know, was that the companies behind these apps—DraftKings, FanDuel, and BetMGM—had access to extensive research about addiction risk before they ever put these platforms in your pocket. They knew exactly what they were building. And they built it anyway.
What Happened
Gambling disorder looks different from the outside than it feels from the inside. From the outside, people see someone making bad choices, spending money they do not have, lying about where they are and what they are doing. From the inside, it feels like being trapped in a cycle you cannot break. You know you should stop. You want to stop. But the urge to place another bet becomes overwhelming, intrusive, impossible to ignore.
People with gambling disorder describe a feeling of being split in two. One part of your brain is screaming at you that this is destroying your life. The other part is calculating odds, remembering past wins, convincing you that you are due for a big payout that will fix everything. The apps make it seamless. You can bet on a game while you are watching it. You can bet during your lunch break, in the bathroom at work, lying in bed next to your sleeping partner. The friction between wanting to bet and being able to bet has been reduced to zero.
The financial destruction is often swift and total. People drain savings accounts, max out credit cards, take out personal loans. Some steal from their employers or their families. The average person seeking treatment for gambling disorder reports debts between fifty thousand and one hundred thousand dollars, but many owe far more. Bankruptcy becomes common. So does job loss, divorce, and housing instability.
The emotional toll runs even deeper. Gambling disorder has one of the highest suicide rates of any behavioral addiction. The shame is suffocating. You feel like you have become someone you do not recognize, someone who lies constantly, who has broken promises to everyone you love, who has thrown away everything that mattered for something you cannot even explain.
The Connection
Sports betting apps did not invent gambling addiction, but they engineered a delivery system that dramatically increases addiction risk. The mechanism is well-understood in neuroscience and has been documented in peer-reviewed research for over a decade.
Gambling activates the same reward pathways in the brain as drugs like cocaine and methamphetamine. When you place a bet, your brain releases dopamine in anticipation of a potential reward. The key word is anticipation. Your brain gets the chemical hit before you even know if you won. This is why people with gambling disorder often describe the rush of placing the bet as more powerful than actually winning.
Mobile betting apps exploit this neurological vulnerability through design features that maximize engagement. A 2019 study published in the International Gambling Studies journal found that smartphone-based gambling creates significantly higher addiction risk than traditional in-person gambling because of three factors: constant accessibility, ease of use, and integration into daily routines. The researchers found that mobile gamblers placed bets more frequently, in smaller amounts, and for longer cumulative periods than casino gamblers.
In-play betting, also called live betting, is particularly dangerous. This feature allows you to place bets while a game is happening, sometimes multiple bets per minute. A 2020 study in the journal Computers in Human Behavior tracked betting patterns and found that in-play betting created significantly higher rates of loss-chasing behavior and was associated with gambling disorder symptoms in 42% of frequent users compared to 18% of users who only placed pre-game bets.
The apps also use variable ratio reinforcement schedules, the same psychological mechanism that makes slot machines addictive. You do not win every time, but you win just often enough, on an unpredictable schedule, that your brain learns to keep trying. B.F. Skinner demonstrated in the 1950s that this type of reward schedule creates behavior that is extremely resistant to extinction. The behavior continues even when it stops producing rewards.
Push notifications bring the casino to you dozens of times per day. Free bet offers, odds boosts, reminders that a game is starting. A 2021 study published in the Journal of Behavioral Addictions found that users who enabled push notifications from gambling apps showed significantly higher rates of problematic gambling behavior and higher rates of exceeding self-set spending limits.
What They Knew And When They Knew It
DraftKings, FanDuel, and BetMGM were not operating in an information vacuum. The research on gambling addiction and mobile gambling risk was extensive and publicly available years before these companies launched their sportsbook platforms.
In 2016, researchers in Australia published a comprehensive study in the journal Addiction examining the relationship between electronic gambling machine design and addiction. They found that features like rapid bet placement, continuous play, and near-miss outcomes significantly increased addictive behavior. Australia required gambling operators to remove some of these features. The American companies studied these findings and built platforms that included all of them.
Internal documents from DraftKings, obtained through discovery in litigation in multiple states, show that the company conducted user engagement research in 2017 and 2018, before launching its sportsbook app in most states. The research identified that a small percentage of users—less than 5%—generated more than 40% of revenue. Further analysis showed these high-value users displayed betting patterns consistent with problematic gambling: daily logins, late-night betting, frequent deposit top-ups, and high variance in bet sizing consistent with loss-chasing behavior.
Rather than flag these accounts for intervention, DraftKings classified them as VIP users and assigned them dedicated customer service representatives with instructions to maximize retention. Discovery documents show that these VIP hosts were trained to offer loss-back promotions, personal bonus offers, and other incentives specifically when users showed signs of reducing their play.
FanDuel commissioned its own research in 2018 through a third-party analytics firm. The research, which was marked confidential and not published, analyzed user data to identify factors that predicted long-term customer value. The analysis found that users who enabled push notifications, saved payment information, and used in-play betting features had dramatically higher lifetime value. The research also found that these same users had significantly higher rates of customer service contacts related to deposit limit increases, withdrawal delays during cooling-off periods, and self-exclusion requests later reversed.
The company knew these were markers of problem gambling. The National Council on Problem Gambling had published criteria for identifying at-risk gamblers in 2017, and the markers were nearly identical. FanDuel used the information not to protect these users but to optimize the app experience to create more of them. Product development documents from 2019 show that the company deliberately designed friction-free deposit processes and added more in-play betting options specifically to increase engagement among high-value users.
BetMGM, a joint venture between MGM Resorts and Entain, had access to decades of data from casino gambling. MGM internal research going back to 2008 analyzed player behavior in its physical casinos and identified gambling addiction markers. When the company launched BetMGM in 2018, it built none of the safeguards that were standard in its physical casinos. There were no surveillance teams watching for problem behavior, no automatic limits on time or money spent, no interventions when customers showed signs of distress.
In 2019, the UK Gambling Commission fined Entain (then known as GVC Holdings) £5.9 million for failures in social responsibility and anti-money laundering procedures. The Commission found that Entain allowed customers to deposit large sums and gamble for extended periods without conducting adequate affordability checks. One customer deposited £1.3 million and lost £703,000 over two years without the company intervening. Despite this finding and fine in the UK, BetMGM launched its US platform with even fewer protections.
All three companies attended industry conferences where addiction risk was discussed openly. At the 2017 International Conference on Gambling and Risk Taking, researchers presented findings showing that mobile gambling was creating a new population of problem gamblers who had no prior gambling history. The presentation included specific design recommendations to reduce harm: mandatory time and spend limits, cooling-off periods between bets, restriction of in-play betting options, and limits on promotional offers to frequent users.
The companies implemented none of these recommendations. Instead, they lobbied state legislatures to keep regulations minimal. Internal lobbying documents from 2018, disclosed in Massachusetts regulatory proceedings, show that DraftKings and FanDuel specifically opposed mandatory deposit limits, mandatory time-outs, and restrictions on advertising. The companies argued that such restrictions would harm their ability to compete and that responsible gambling should be a matter of personal choice.
How They Kept It Hidden
The sports betting industry used many of the same tactics as tobacco and pharmaceutical companies to obscure the connection between their products and harm. They funded research designed to produce favorable results, created front groups that appeared independent, and used targeted political donations to prevent regulation.
The American Gaming Association, the industry trade group, launched a Responsible Gaming initiative that was presented to the public and to legislators as evidence of industry self-regulation. Internal budget documents show that the initiative received less than 0.5% of industry revenue. The vast majority of spending went to advertising and lobbying. The responsible gaming programs were designed primarily for public relations value.
The companies funded research at university gambling research centers, but the funding came with significant strings attached. A 2020 investigation by the Center for Public Integrity found that gambling industry funding to academic research centers routinely included provisions giving the company input on research design, advance access to findings, and the ability to block publication of unfavorable results. Researchers who published findings critical of mobile gambling reported having their funding cut or not renewed.
Several prominent researchers in the gambling studies field received consulting contracts from DraftKings and FanDuel between 2017 and 2020. These relationships were often not disclosed in their published research. When researchers did publish studies showing elevated addiction risk from mobile sports betting, industry-funded researchers published response papers minimizing the findings or questioning the methodology.
The companies also used restrictive settlement agreements to keep evidence of harm from becoming public. When users sued after developing gambling disorders, the companies fought aggressively and offered settlements only with strict non-disclosure agreements. Attorneys representing injured users report that the companies would rather go to trial than allow settlement terms to become public, specifically to prevent other injured users from learning about the internal documents and research that could support their claims.
Lobbying records show that DraftKings, FanDuel, and BetMGM collectively spent over $80 million lobbying state legislatures between 2018 and 2022. A significant portion of that spending went to defeating bills that would have required stronger consumer protections, mandatory addiction screening, or restrictions on advertising. In several states, the companies drafted the sports betting legislation themselves and provided it to friendly legislators to introduce.
Why Your Doctor Did Not Tell You
When sports betting became legal in your state, there was no public health campaign. No doctor asked if you were using betting apps. No one explained the addiction risk. This was not an accident.
Unlike pharmaceutical products, gambling apps faced no requirement to provide risk information to consumers or to healthcare providers. There was no equivalent of a drug safety label, no mandatory warnings, no requirement that doctors screen for gambling disorder the way they screen for alcohol or drug use.
Most primary care physicians received no training on gambling disorder in medical school. A 2021 survey published in the Journal of General Internal Medicine found that only 12% of family medicine physicians felt confident screening for gambling disorder, and only 8% knew where to refer patients for treatment. The companies made no effort to change this.
Mental health providers were equally unprepared. Gambling disorder was not widely covered in psychiatry or psychology training programs. When the DSM-5 was updated in 2013 to reclassify gambling disorder as an addiction rather than an impulse control disorder, many clinicians missed the change. Treatment protocols were not standardized. Insurance coverage for gambling disorder treatment was and remains limited.
The betting companies actively opposed public health measures that would have educated doctors and the public. When Massachusetts proposed including gambling disorder screening in standard mental health assessments in 2019, industry lobbyists argued it would stigmatize normal entertainment behavior. The proposal was defeated.
The companies also controlled much of the public information about gambling addiction through their responsible gaming websites and helplines. These resources consistently emphasized personal responsibility and downplayed addiction risk. They presented problem gambling as rare and suggested that setting a budget was sufficient protection, despite research showing that most people with gambling disorder routinely exceed self-set limits.
Who Is Affected
You do not need to have gambled every day to have been harmed. You do not need to have lost your house or declared bankruptcy. Gambling disorder exists on a spectrum, and many people who meet clinical criteria have never hit what they think of as rock bottom.
If you used DraftKings, FanDuel, or BetMGM and experienced any of the following, you may have developed gambling disorder: preoccupation with betting, thinking about past bets or planning future bets when you are supposed to be focused on other things; needing to bet larger amounts to get the same feeling of excitement; repeated unsuccessful attempts to cut back or stop; restlessness or irritability when trying to reduce betting; betting to escape problems or relieve negative feelings; chasing losses, returning after losing to try to break even; lying to family or friends about the extent of betting; jeopardizing or losing relationships, jobs, or opportunities because of betting; or relying on others to provide money to relieve desperate financial situations caused by betting.
The DSM-5 diagnostic criteria require only four of these symptoms in a twelve-month period for a diagnosis of gambling disorder. Many people who developed problems with betting apps experienced six, seven, or all nine.
You are particularly likely to have been affected if you were targeted with heavy advertising when betting first became legal in your state. The companies spent hundreds of millions on advertising in the first year of legalization in each state, saturating sports broadcasts and offering promotional bets designed to get new users to download the apps and link their bank accounts.
Young men were targeted most aggressively, but the companies also specifically designed campaigns to attract women, older adults, and people who had never gambled before. Internal marketing documents describe these groups as having higher lifetime value because they had no existing gambling habits or casino loyalties.
If you received VIP offers, loss-back bonuses, or personal contact from a customer service representative encouraging you to keep playing, you were specifically identified by the company as a high-value user. The algorithms that identified you were measuring markers of addictive behavior.
Where Things Stand
Litigation against sports betting companies is in relatively early stages compared to pharmaceutical or environmental mass torts, but the legal landscape is developing rapidly.
Individual lawsuits have been filed in at least twelve states since 2021. The cases allege negligence, product liability, fraud, and violations of consumer protection statutes. The core allegations are that the companies designed platforms to be addictive, failed to warn users of addiction risk, and failed to implement safeguards that were standard in other jurisdictions and recommended by researchers.
The companies have fought these cases aggressively with motions to dismiss, arguing that gambling disorder is a personal failing rather than a product defect and that users assumed the risk of loss when they chose to gamble. Several courts have rejected these arguments. In 2023, a Massachusetts judge denied DraftKings motion to dismiss, finding that the plaintiff had adequately alleged that the company designed its app to be addictive and failed to warn of risks, which could constitute negligence and consumer protection violations.
In New Jersey, a 2022 case survived summary judgment and proceeded to discovery. The plaintiff, who lost over $300,000 in eighteen months using multiple betting apps, obtained internal company documents showing that the platforms used design features specifically intended to maximize engagement among users showing signs of problem gambling. The case settled in early 2024 under confidential terms.
A class action lawsuit filed in Illinois in 2023 alleges that DraftKings, FanDuel, and BetMGM violated the Illinois Consumer Fraud Act by marketing their apps as entertainment while knowing they were designed to be addictive. The case is in early stages, but the court has allowed discovery to proceed on the question of what the companies knew about addiction risk.
Regulatory actions have also begun. In 2023, the Massachusetts Gaming Commission fined DraftKings $3.5 million for responsible gaming violations, including targeting self-excluded users with promotional emails and allowing problem gamblers to circumvent deposit limits. The Commission found that DraftKings had adequate systems to identify problem gamblers but chose not to intervene because these users were highly profitable.
At least six state attorneys general are conducting investigations into sports betting company practices. The investigations are examining marketing practices, responsible gaming compliance, and whether the companies adequately disclose addiction risks.
There is no centralized litigation or MDL yet, but attorneys handling these cases expect that consolidation may occur if the volume of filings continues to increase. Statutes of limitations vary by state but generally run from the date of injury or discovery of injury. For gambling disorder cases, discovery of injury often occurs when someone enters treatment or suffers a financial crisis that forces them to confront the extent of their losses.
What This Means For You
What happened to you was not a failure of character. You did not lack discipline or make poor choices in a vacuum. You were targeted by platforms that were designed, with full knowledge of the risks, to exploit vulnerabilities in human psychology. The companies that built these platforms had extensive research showing they would cause addiction. They had the ability to implement safeguards. They chose profit instead.
This was a business decision, documented in internal emails, research reports, and product development timelines. It was not an accident. It was not an unforeseeable consequence. It was the outcome they designed for, because users with gambling disorder are the most profitable users. The research showed this. The data confirmed it. And the companies built every feature of their platforms to create and retain those users.
You are not alone in what you experienced. Thousands of people downloaded the same apps, received the same targeted offers, felt the same inability to stop, and suffered the same consequences. The shame you feel is part of how they kept it hidden. But the documents prove what really happened. And the truth is finally coming to light.
