You told yourself it was just entertainment. A way to make watching the game more interesting. Five dollars here, ten dollars there. The apps made it so easy—bright colors, instant deposits, a notification every time your team scored. You could place a bet during a commercial break. You could bet on the next pitch, the next play, whether the next free throw would go in. The action never stopped, and neither did you.
Then one day you looked at your bank account and felt your stomach drop. Thousands gone. Maybe tens of thousands. You had been so certain the next bet would win it back. You remembered staying up until 3am watching west coast games you did not care about because you had money on them. You remembered lying to your spouse about where the money went. You remembered the panic, the shame, the absolute inability to stop even when you knew you were destroying everything you had built.
Your doctor used the term gambling disorder. You felt a wave of confusion and then rage. You were not a gambler. You had never set foot in a casino. You were just trying to have fun with an app that every sports network advertised during every single game. How did it come to this?
What Happened
Gambling disorder is a recognized addiction classified in the Diagnostic and Statistical Manual of Mental Disorders. It works on your brain the same way substance addictions do, flooding your neural pathways with dopamine during moments of anticipation and win, then crashing you into despair during losses. But the crash does not stop you. It drives you to chase your losses, to bet more, to try to win back what you lost.
People with gambling disorder experience an inability to control their betting despite serious consequences. They think about gambling constantly. They need to bet more and more money to feel the same excitement. They become restless and irritable when they try to stop. They lie to family members. They drain savings accounts, max out credit cards, borrow from friends, sometimes steal. They lose jobs because they are betting at work. They lose marriages. Some lose their lives.
The financial devastation is often total. People report losing everything—retirement accounts, college funds, home equity. They describe a feeling of being in a trance while betting, of hours disappearing, of a compulsion so strong it overrides every rational thought. Many describe suicidal thoughts when they finally confront what they have done.
Relationships collapse under the weight of lies and financial ruin. Spouses feel betrayed. Children lose their sense of security. The person with gambling disorder feels unbearable shame but cannot stop. They make promises and break them. They truly believe each time that they will stop after one more bet.
The Connection
Sports betting apps are not like traditional gambling. They were designed using decades of research into behavioral psychology and addiction mechanisms. Every feature was built to maximize engagement, which in this industry means maximizing betting frequency and total amount wagered.
The speed is the first factor. Traditional sports betting meant placing a wager before a game started and waiting hours for the result. Mobile sports betting apps offer in-play or live betting, which allows users to place bets every few seconds throughout a game. A 2020 study published in the journal Addictive Behaviors found that live betting is significantly more addictive than traditional pre-game betting because it creates continuous dopamine cycling and eliminates the natural pause that allowed gamblers to disengage.
The apps use push notifications to bring users back constantly. These notifications are triggered by game events, promotional offers, and personalized betting suggestions based on your previous activity. A 2021 study in the International Gambling Studies journal documented how notifications create a sense of urgency and FOMO—fear of missing out—that drives compulsive checking and betting behavior.
The platforms offer hundreds of micro-betting options per game. You can bet on individual at-bats, individual plays, individual possessions. This granularity means that someone can place fifty bets during a single game, creating a slot-machine-like experience of constant action and constant dopamine hits. Research published in 2019 in the Journal of Behavioral Addictions confirmed that event frequency is one of the strongest predictors of gambling addiction—the more opportunities to bet, the faster addiction develops.
The apps also use sophisticated algorithms to offer personalized promotions. If you are losing, you might receive a bonus offer. If you have not bet in a few days, you might receive a risk-free bet promotion. These are not random. They are triggered by user behavior patterns designed to pull you back in at the exact moment you might disengage.
Credit systems disguise real money. You deposit dollars but bet with virtual credits or points. Research has shown for decades that people bet more when they are using tokens or credits rather than physical cash because the psychological pain of loss is reduced. The apps know this.
What They Knew And When They Knew It
DraftKings was founded in 2012, FanDuel in 2009, both initially as daily fantasy sports platforms. When the Supreme Court struck down the federal sports betting ban in May 2018, these companies immediately pivoted to sports betting apps. BetMGM launched in 2018 as a joint venture between MGM Resorts and Entain, a British gambling company with decades of experience in the betting industry.
These companies knew exactly what they were building. Entain, BetMGM's parent company, had been operating in the United Kingdom and Europe for years, where extensive research and regulatory data already existed on mobile gambling addiction. A 2016 UK Gambling Commission report documented that remote gambling—online and mobile betting—had the highest rates of problem gambling, with 7.3 percent of remote gamblers classified as problem gamblers compared to 2.7 percent of all gamblers. Entain had access to this data.
In 2019, internal documents from Flutter Entertainment, the parent company of FanDuel, revealed that the company tracked which customers were showing signs of problem gambling and that these high-risk customers were disproportionately profitable. A 2020 investigation by The Guardian found that Flutter identified certain customers as likely problem gamblers but continued to market to them because they generated outsized revenue. Flutter acquired FanDuel in full in 2018.
DraftKings went public via a reverse merger in April 2020. In the investor documents filed with the SEC, the company acknowledged that a significant portion of revenue comes from a small percentage of highly active users. Internal metrics showed that approximately 5 percent of users generated nearly 40 percent of revenue. The company knew that heavy users—those betting daily or multiple times per day—were the profit center. They also knew from decades of gambling research that this usage pattern is the clinical definition of gambling disorder.
In 2021, an investigation by Reuters obtained data showing that DraftKings had hired a team of behavioral psychologists and user experience designers specifically to maximize engagement and increase betting frequency. The company tested different notification frequencies, different color schemes for buttons, different sounds for wins and losses. Every element was optimized to keep users betting.
BetMGM's parent company MGM Resorts had been studying gambling behavior in its casinos for decades. The company employed behavioral scientists who published research on slot machine design and casino layout optimization. When MGM entered the mobile betting market, it brought this expertise. A 2017 internal training document from MGM, later disclosed in litigation, explicitly discussed the importance of speed of play and frequency of betting opportunities in driving revenue. The document stated that the goal was to minimize the time between bet and result and maximize the number of betting opportunities per hour.
All three companies knew about responsible gambling research. The National Council on Problem Gambling has published guidelines for safer gambling design since 2003. These guidelines recommend mandatory timeouts, deposit limits set before play begins, no credit betting, and cooling-off periods. The apps implemented some voluntary tools but made them difficult to find and easy to bypass. They never implemented mandatory limits.
In 2020, FanDuel settled with the New Jersey Division of Gaming Enforcement for violations including marketing to self-excluded gamblers and allowing problem gamblers to continue betting without intervention. The settlement documents showed that FanDuel had the technology to identify at-risk users but chose not to implement automatic protections.
How They Kept It Hidden
The sports betting industry formed trade associations that funded research designed to minimize the appearance of harm. The American Gaming Association, which counts DraftKings, FanDuel, and BetMGM as members, has funded studies on economic benefits of legalized sports betting while staying conspicuously silent on addiction rates.
The companies formed partnerships with sports leagues and teams, effectively buying silence. The NBA, NFL, MLB, and NHL all signed lucrative official betting partnerships. These leagues now have financial incentives to downplay gambling harm. The leagues receive a percentage of betting revenue in many states and charge licensing fees for use of league data. This created a powerful coalition with no interest in discussing addiction.
The advertising strategy was to normalize betting as part of sports fandom. The companies spent billions on commercials during sporting events, featuring celebrities and athletes, framing betting as entertainment and skill rather than gambling. They avoided the word gambling in many ads, using terms like sports gaming or sports entertainment. This was a deliberate strategy to distance their products from the stigma and known risks of traditional gambling.
The companies lobbied state legislatures during the legalization process. Internal lobbying documents later obtained through public records requests showed that industry representatives specifically pushed back against strong responsible gambling provisions. They argued that overly strict regulations would push users to illegal offshore sites, a claim used to water down deposit limits, mandatory timeouts, and advertising restrictions in numerous states.
When harm stories emerged, the companies pointed to voluntary responsible gambling tools. They featured these tools in testimony and in response to media inquiries. But internal data, disclosed in litigation, showed that the tools were rarely used because they were buried in settings menus, required multiple clicks to activate, and could be turned off instantly. The existence of the tools provided legal and public relations cover while doing almost nothing to prevent harm.
Settlement agreements in the cases that have been filed typically include non-disclosure agreements. People who were harmed and who reached settlements cannot talk about what happened to them or what they learned in discovery. This keeps the evidence fragmented and prevents public awareness of the patterns.
Why Your Doctor Did Not Tell You
Your doctor did not know because gambling disorder in the context of sports betting apps is relatively new and because the medical community was not educated about the risk. Gambling disorder has been recognized since the 1980s, but it was associated primarily with casinos, poker, and horse racing. The medical literature did not catch up to the smartphone era until recently.
Sports betting apps launched at scale in most states between 2018 and 2021. Doctors are trained on information that typically lags several years behind emerging risks. Medical school curricula and continuing education programs had minimal content on gambling disorder, and almost nothing specific to mobile sports betting.
The apps marketed themselves as entertainment and skill-based games, not gambling. This messaging reached doctors too. Many physicians did not understand that sports betting apps function as high-speed, high-frequency gambling products more similar to slot machines than to traditional sports betting.
There was no public health campaign. When opioid addiction became an epidemic, there were CDC guidelines, medical alerts, prescription monitoring programs. Nothing equivalent happened for sports betting addiction, even as emergency room visits and calls to gambling helplines surged in states after legalization. A 2022 study published in JAMA Network Open documented a 30 percent increase in gambling-related harm calls in states within two years of legalizing mobile sports betting.
The companies did not provide risk information to healthcare providers. Pharmaceutical companies are required to distribute prescribing information and black box warnings. Betting apps had no equivalent requirement. They were regulated as gaming, not as products with addiction potential, so doctors received no structured information about risk factors, warning signs, or treatment protocols.
Where Things Stand
Lawsuits have been filed against DraftKings, FanDuel, and BetMGM by individuals who developed gambling disorder and by family members of people who died by suicide after losing catastrophic sums. The first cases were filed in 2022 and 2023. The claims include negligence, failure to warn, deceptive trade practices, and violation of consumer protection statutes.
The legal theories focus on defective product design—that the apps were designed to be addictive and that the companies knew of the addiction risk but failed to implement safeguards. Plaintiffs argue that the apps are unreasonably dangerous and that the voluntary responsible gambling tools are inadequate and were designed to fail.
Discovery in these cases has begun producing internal documents. Several cases are in the motion to dismiss phase, with companies arguing that gambling is a known risk and that users assumed that risk. Courts have issued mixed rulings. Some have allowed negligence and consumer protection claims to proceed, finding that the specific design features and marketing practices create questions of fact that cannot be resolved on a motion to dismiss.
A class action lawsuit was filed in New Jersey in 2023 alleging that FanDuel violated consumer protection laws by marketing to vulnerable users and failing to implement adequate safeguards. That case is ongoing. Additional class actions have been filed in other states with similar claims against all three companies.
Regulatory action has been limited. Some states have fined the companies for specific violations like allowing self-excluded gamblers to bet or marketing to minors, but no state has forced significant design changes. The fines have been small relative to company revenue—typically in the hundreds of thousands of dollars while the companies generate billions in annual revenue.
There is no settlement fund or resolution program yet. The litigation is in relatively early stages. Based on the timeline of other mass tort cases, it could be several years before any large-scale settlements occur, but the volume of cases is growing as more people come forward and more attorneys investigate the claims.
If you developed gambling disorder after using sports betting apps, your situation may qualify for legal action. The relevant factors include how much you lost, whether you were targeted with personalized promotions, whether you tried to use responsible gambling tools and found them ineffective, and whether you experienced documented harm such as bankruptcy, loss of employment, or mental health crisis. There is no specific minimum loss amount established across cases, but significant financial and personal harm strengthens a claim.
Who Is Affected
You may be affected if you used DraftKings, FanDuel, BetMGM, or other mobile sports betting apps and developed an inability to control your betting. The pattern typically looks like this: you started casually, maybe placing a few bets per week. Over time, you bet more frequently. You started betting on games you did not care about just to have action. You increased your bet sizes to feel the same excitement. You chased losses by placing more bets to try to win back what you lost.
You may have found yourself thinking about betting constantly, checking scores and lines even when you were at work or with family. You may have hidden your betting from loved ones or lied about how much you were losing. You may have drained bank accounts, borrowed money, or used credit cards to fund your betting. You may have felt unable to stop even when you knew it was destroying your finances and relationships.
The apps may have sent you promotions when you were losing or when you had not bet in a while. You may have received personalized offers that seemed designed to pull you back in. You may have tried to set limits or self-exclude but found the process confusing or easy to bypass.
Many people affected were not traditional gamblers. They had never had a problem with casinos or poker. They started betting on sports because it was advertised as part of being a sports fan. They were told it was entertainment, not gambling. They did not recognize the signs of addiction until they had lost everything.
Young men have been disproportionately affected. Data from gambling helplines shows a sharp increase in calls from men under 40 since sports betting apps launched. But women, older adults, and people with no prior gambling history have also developed gambling disorder from these apps. The common factor is not demographics but exposure to a product designed to maximize addictive engagement.
Where Things Stand
As of 2024, there are dozens of individual lawsuits filed against the major sports betting apps and several class actions in various stages. The cases are not consolidated into a multidistrict litigation yet, but attorneys are coordinating strategy across jurisdictions.
The companies are fighting the cases aggressively. Their primary defense is that gambling is a known risk and that users chose to participate. They point to terms of service that users agreed to and to the existence of voluntary responsible gambling tools. They argue that they complied with all applicable state regulations.
Plaintiffs counter that the apps were designed to be addictive in ways that traditional gambling was not, that the companies used behavioral science to maximize compulsive use, and that they knew heavy users were exhibiting signs of addiction but continued to market to them because they were the most profitable segment.
The discovery process is revealing significant internal documentation. Emails, strategy documents, and research reports are showing what the companies knew about user behavior and addiction risk. Some documents show explicit discussion of maximizing engagement among heavy users. Others show that the companies tracked problem gambling indicators but did not implement automatic interventions.
There have been no major settlements yet, but the litigation is progressing. Several cases have survived motions to dismiss, which is a critical threshold. Once cases are in discovery and approaching trial, settlement discussions typically become more serious.
Some states are beginning to consider stronger regulations. There have been legislative proposals to ban in-play betting, to require mandatory deposit limits, to restrict advertising, and to fund problem gambling treatment through taxes on betting revenue. The industry is lobbying against these measures, but public awareness is growing as more harm stories emerge.
If you believe you were harmed by sports betting apps, documentation is important. Bank statements showing deposits and losses, records of communications from the apps, medical records if you sought treatment for gambling disorder or related mental health issues, and any evidence of financial consequences like bankruptcy filings or loan defaults can all be relevant.
The timeline for resolution is uncertain. Mass tort cases typically take years from initial filing to settlement or verdict. But the volume of people affected is large and growing, and the internal documents emerging in discovery are creating a clear record of what the companies knew and when they knew it.
What happened to you was not a personal failure. It was not a lack of willpower or a character flaw. You were exposed to a product that was designed, tested, and optimized to be addictive. The companies that built these apps employed teams of psychologists and behavioral scientists to make them as engaging as possible, which in the gambling industry means as addictive as possible. They knew that a subset of users would develop gambling disorder. They knew these users would be their most valuable customers. And they built the apps anyway, with features specifically designed to maximize the behaviors that define addiction.
You were told it was entertainment. You were told it was a way to be part of the game. You were not told that the app was tracking your every behavior, that it was sending you notifications timed to your moments of weakness, that it was designed to keep you in a cycle of dopamine hits and desperate chasing. You were not told any of this because the companies made a business decision that your addiction was worth more than your wellbeing. That decision is now documented in their own internal records.
