A federal lawsuit filed in March 2026 alleges that major sports betting platforms—including DraftKings and FanDuel—deliberately design their apps to push users toward risky “microbetting” or proposition bets that are engineered to drive gambling addiction. The lawsuit, brought by the Public Health Advocacy Institute against DraftKings, FanDuel, Genius Sports Ltd., and the NFL, claims these in-game betting products are “inherently dangerous” and marketed specifically to encourage excessive, repetitive wagering. The case centers on a troubling practice: allowing continuous live bets during games on outcomes like halftime scores, the largest lead, or successful third-downs—creating a gambling experience designed with no natural stopping points. One plaintiff’s story illustrates the severity.
A Pennsylvania man identified as Thompson lost over $1.8 million to these microbets and found himself contemplating suicide after his final losing bet in February 2026. In desperation to fund his growing addiction, Thompson took out second and third mortgages on his family home. Both mortgages are now in default. After losing nearly everything, Thompson entered rehabilitation and was formally diagnosed with a gambling addiction disorder. His case exemplifies what the lawsuit alleges: that sports betting platforms have knowingly built products designed to trap users in cycles of addiction rather than facilitate responsible wagering.

What Are Proposition Bets and How Do Sports Betting Apps Push Them?
Proposition bets—or “props”—are wagers on specific in-game outcomes rather than the final score. Microbetting takes this further by allowing bets to be placed during the game at any moment: on the next play, the next series outcome, whether the next possession will result in a field goal, or dozens of other micro-outcomes. Unlike traditional pre-game betting where you place a bet and wait for the game to conclude, microbetting creates a constant stream of new wagering opportunities every few seconds.
The lawsuit alleges that platforms use aggressive promotional tactics to encourage users toward these bets specifically. Plaintiffs describe receiving repeated push notifications offering bonus credits, VIP status rewards, and “enhanced odds” promotions—all designed to keep users engaged and placing bets continuously. Misleading advertising portrays microbetting as entertainment or skill-based gaming, when the platforms’ own internal data shows the odds heavily favor the house. The speed and frequency of these bets mirror the mechanics of slot machines far more closely than traditional sports betting, with no built-in pauses or “offramps” that would allow a user to step back and reassess their spending.
The Addiction Mechanics Built Into Continuous Betting
Microbetting operates differently from traditional wagering in ways that directly exploit psychological vulnerabilities to addiction. The constant flow of new betting opportunities creates what researchers call “continuous reinforcement”—a mechanism proven to drive compulsive behavior. A user never has to stop; as soon as one bet resolves, another option appears. This contrasts sharply with traditional sports betting, where you place a bet pregame and must wait hours for resolution, providing natural moments for reflection and restraint.
The lawsuit describes this design as deliberately engineered to maximize “betting behavior that leads to addiction.” Mental health experts note that the speed of microbetting—with outcomes resolving in seconds—mimics the neurological hooks of slot machine gambling, where rapid wins and losses create a powerful dopamine cycle. The platforms understand this mechanism; their algorithms track user behavior in real-time and adjust promotions and notification patterns to keep high-loss users engaged. Critically, users aren’t warned about these psychological mechanisms. The platforms don’t disclose that the continuous-action design is known to increase gambling disorder risk, nor do they provide adequate tools to pause or self-exclude during active games.
Financial and Mental Health Consequences for Users
The financial impact extends far beyond lost wagers. Thompson’s experience—losing $1.8 million and mortgaging his home multiple times—represents an extreme but increasingly documented outcome. Class action filings describe similar patterns: users who start with small bets and, over weeks or months, escalate their wagering to recover losses. Microbetting’s speed accelerates this cycle; losing a series of prop bets over 90 minutes can result in losses that would take days or weeks in traditional betting contexts.
The mental health toll has proven equally severe. Gambling addiction rates among young adult men have tripled since the legalization of online sports betting, with microbetting cited as a primary driver. Thompson’s near-suicidal ideation after his final loss is not unique—crisis hotlines report sharp increases in calls from gamblers during major sporting events. Rehabilitation facilities report filling beds with people in their 20s and 30s dealing with sports betting addiction, many of whom describe microbetting as their entry point into problem gambling. The lawsuit argues that platforms knowingly built products that increase addiction risk without implementing corresponding protections or honest disclosures.
Predatory Marketing and Tactics Designed to Encourage Excessive Betting
The lawsuit identifies specific promotional tactics that platforms deploy to encourage excessive wagering. These include: bonus credit offers that incentivize first-time users to place more bets than they otherwise would; VIP “reward” programs that provide escalating benefits as users lose more money; misleading advertisements suggesting that betting can be a profitable activity; and algorithmic push notifications timed to capture user attention during high-emotion moments in games. One particularly problematic tactic involves “loss chasing” incentives.
When a user loses a bet, the app often immediately offers a bonus or promotional credit, creating a false psychological sense that the loss can be recovered. This directly exploits a cognitive bias known to drive gambling disorders. Additionally, platforms employ sophisticated data analytics to identify vulnerable users—those who gamble frequently or on credit—and target them with promotions designed to increase their betting volume. The lawsuit alleges this amounts to deliberately targeting individuals at risk for addiction, then optimizing the product experience to deepen that addiction.
Regulatory Gaps and Why Existing Protections Fall Short
Currently, online sports betting operates under a patchwork of state regulations that were designed primarily to generate tax revenue rather than protect consumers from addiction. Most states allow licensed operators broad latitude in their promotional practices and product design, provided they verify users are 21 or older and comply with basic responsible gambling disclosures. However, these disclosures are often buried in terms of service or presented as minimal warnings that do little to inform users of actual risk.
The lawsuit argues that existing regulatory frameworks are inadequate because they treat all betting products as equivalent, failing to account for the documented addiction risk associated with microbetting specifically. Traditional sports betting on game outcomes carries measurable risk, but the continuous-action design of microbetting introduces psychological mechanisms that are distinctly more dangerous. Federal regulators have not issued guidance on these products, and state regulators have largely declined to restrict them, leaving platforms free to design products with addiction risk as a built-in feature.
Who Can File a Claim and What Damages Look Like
Potential claimants in related lawsuits are users who lost significant sums to sports betting apps, particularly those who used microbetting features, and who developed gambling addiction disorders as a result. The legal theory rests on product liability: the apps are allegedly “defective” because they were designed with features that make them unreasonably dangerous when used as intended.
Damages in these cases typically include actual financial losses, though courts have begun recognizing additional harms such as therapy and rehabilitation costs, lost income due to gambling-related mental health crises, and in some cases family law proceedings (divorce, custody issues arising from financial devastation). The March 2026 lawsuit seeks class certification, which could allow thousands or millions of affected users to join the claim and recover damages collectively rather than individually.
Where the Lawsuit Stands and What to Expect
The March 2026 filing by the Public Health Advocacy Institute represents one of the first major legal challenges to sports betting platforms’ business models rather than just their marketing practices. Previous lawsuits have focused on specific deceptive ads or false promotions; this lawsuit goes further, arguing that the fundamental product design—microbetting itself—is inherently unsafe and designed to addict.
The case is expected to face vigorous defense from the platforms, which will likely argue that users bear responsibility for their gambling choices and that the apps include responsible gambling tools. However, the lawsuit’s focus on the products’ design mechanisms rather than individual choice provides a different legal theory that has succeeded in other product liability contexts, from tobacco to opioids. As the case develops, expect to see discovery that reveals how platforms designed these features, what internal data shows about addiction risks, and whether executives knowingly built these mechanisms to maximize engagement and revenue at users’ expense.
Conclusion
The lawsuit against DraftKings, FanDuel, and others represents a significant escalation in the legal challenge to sports betting platforms’ business practices. By focusing on microbetting as an inherently dangerous product rather than simply attacking misleading promotions, plaintiffs are attempting to shift the entire legal and regulatory conversation around online gambling. The case of Thompson—a user who lost $1.8 million and nearly his life to these products—underscores that the harms are not theoretical; they are destroying real families and lives right now.
If you’ve experienced significant losses through sports betting apps, particularly through microbetting features, and have been diagnosed with or treated for gambling addiction, you may have grounds for a claim. Consulting with an attorney who specializes in product liability or consumer protection lawsuits is an important first step. Class action lawsuits can provide a path to recovery even if individual claims seem small; the power comes from aggregating thousands of similar cases. As this litigation develops, more information will emerge about how these platforms were designed and marketed—information that could ultimately change how online betting is regulated and offered to consumers.
