On March 24, 2026, a groundbreaking lawsuit was filed in Philadelphia County, Pennsylvania, accusing DraftKings, FanDuel, Genius Sports, and the National Football League of deliberately using advanced technology and aggressive marketing tactics to create gambling addiction. The case, Sage and Thompson v. DraftKings, Inc. et al., centers on two Pennsylvania residents who suffered catastrophic financial losses after the platforms allegedly targeted them with addictive betting features even after they sought help for gambling addiction.
Christopher Sage lost over $172,000 across both platforms, while Terry Thompson lost approximately $1.86 million, demonstrating the real-world harm these features can inflict on vulnerable consumers. The lawsuit represents a significant escalation in legal accountability for the sports betting industry, which has grown from a $430 million market in 2018 to a $16.96 billion industry in 2025. This case challenges not just the individual sportsbooks, but the underlying infrastructure—including the NFL’s financial interest in gambling expansion—that has fueled rapid growth in high-risk betting features. The plaintiffs allege design defects, failure to warn, negligence, and violations of Pennsylvania consumer protection law, raising questions about whether the current regulatory framework can address the societal costs of this explosive industry.

What Specific Betting Features Are Under Fire in This Lawsuit?
The core of the lawsuit targets “microbetting”—a feature that allows bettors to place wagers on virtually limitless events during a single sporting contest, with odds that change rapidly as the game unfolds. Unlike traditional sports betting, which typically involves wagering on the outcome of an entire game, microbetting fragments the experience into hundreds of micro-transactions: betting on the next play, the next score, a specific player’s performance on the next possession. This constant stream of betting opportunities creates what the lawsuit describes as an “addictive product design” that keeps users engaged throughout an entire game, often lasting several hours. The lawsuit also identifies the VIP Host Program as a key mechanism for driving addiction.
According to court documents, draftkings and FanDuel employ personal mobile phone contact with high-value customers, offering promotional gifts, free sporting event trips, and ongoing encouragement to place more bets. In Christopher Sage’s case, despite registering for self-exclusion in March 2025 after being diagnosed with gambling addiction disorder, he continued receiving contact from a DraftKings VIP host, who essentially re-engaged him in betting activity when he had explicitly sought help. This represents an acute conflict between consumer protection measures and profit-maximization strategies. The defendants also allegedly deployed push notifications designed to promote microbets, creating an additional layer of behavioral nudging. These notifications interrupt users’ daily activities with time-sensitive betting opportunities, exploiting the psychological principle of fear of missing out (FOMO) to drive impulsive wagering.
How Does the Industry’s Use of AI and Machine Learning Amplify These Risks?
The lawsuit alleges that DraftKings, FanDuel, and Genius Sports use artificial intelligence and machine learning to identify and target potentially addicted users—essentially creating algorithmic addiction machines. Rather than using these tools to identify at-risk players and intervene, the industry allegedly weaponizes them to maximize engagement and lifetime customer value, even when doing so causes demonstrable harm. The scale of this algorithmic targeting is staggering. Genius Sports, the data provider behind the lawsuit, powers over 98% of the legalized U.S. sports betting market by controlling the official NFL data feed.
This monopolistic position means that Genius Sports doesn’t just provide a commodity service; it controls the data infrastructure that enables every microbetting feature across the industry. When the NFL maintained its position as the largest shareholder in Genius Sports from 2021 through 2025 (and remains the second-largest shareholder as of March 2026), it created a direct financial incentive for the league to promote the betting features that generate the most engagement—even when those features are designed to exploit vulnerable populations. However, it’s important to understand that not all bettors experience the same risk. Recreational bettors who place occasional wagers on major games face a different risk profile than high-activity microbetters who place hundreds of small wagers daily. The lawsuit does not allege that microbetting itself should be banned, but rather that the platforms’ design, marketing, and data practices deliberately blur the line between entertainment and addiction for a subset of users who cannot control their spending.
Who Are the Plaintiffs and What Financial Harm Did They Suffer?
Christopher Sage, a Pennsylvania resident, lost $42,000 on DraftKings and $130,300 on FanDuel for a combined total of $172,300 across both platforms. In March 2025, Sage received a formal diagnosis of gambling addiction disorder—a recognized mental health condition characterized by an inability to control gambling behavior despite serious negative consequences. Following this diagnosis, Sage took the protective step of registering for self-exclusion, a mechanism that is supposed to prevent him from accessing the gambling platforms and remove him from marketing contact. Despite this clear signal that he was struggling with addiction, DraftKings reportedly continued sending him promotional messages through his VIP host, effectively re-engaging him in the very behavior he was seeking to stop.
Terry Thompson, also a Pennsylvania resident, represents an even more extreme case of the industry’s impact. Thompson began betting on FanDuel in October 2020 and subsequently opened a DraftKings account in 2022. Over the course of his betting activity, Thompson lost approximately $1.52 million on FanDuel and $336,000 on DraftKings, for a combined total of approximately $1.856 million. These losses represent the kind of generational wealth destruction that typically accompanies severe gambling addiction—money that likely was intended for retirement, education, housing, or other essential long-term needs. The lawsuit does not specify whether Thompson sought self-exclusion or received a gambling addiction diagnosis, but the magnitude of his losses over a six-year period suggests a pattern of escalating, compulsive wagering.
What Legal Claims Are the Plaintiffs Bringing Against These Companies?
The lawsuit alleges five distinct causes of action: design defects, failure to warn consumers about dangers, negligence, intentional infliction of emotional distress, and violations of Pennsylvania’s Unfair Trade Practices and Consumer Protection Law. Together, these claims paint a picture of an industry that not only failed to prevent harm but actively designed products to maximize harm while concealing the risks from consumers. The design defect claim is particularly significant.
Rather than alleging that the sportsbooks simply failed to include safety features (a passive omission), the plaintiffs argue that DraftKings and FanDuel affirmatively designed their platforms to be addictive—that the microbetting feature, the VIP host program, the push notifications, and the AI-driven targeting are integrated components of a system intentionally engineered to exploit vulnerable users. This transforms the case from a consumer protection issue into a product liability case, similar to lawsuits against tobacco companies, opioid manufacturers, and social media platforms for exploiting psychological vulnerabilities. The failure-to-warn claim focuses on the industry’s alleged concealment of the addictive potential of these features and the sophisticated targeting mechanisms being used. The IIED (intentional infliction of emotional distress) claim addresses the specific conduct of re-engaging Sage through his VIP host after his self-exclusion request—conduct that the lawsuit characterizes as deliberate cruelty that goes beyond mere negligence.
What Role Did the NFL Play in Creating These Market Conditions?
The NFL’s involvement extends beyond simply allowing its name and image to be used in sports betting. From 2021 through 2025, the NFL was the largest shareholder of Genius Sports, the data provider that powers 98% of legalized U.S. sports betting operations and is a named defendant in this lawsuit. The NFL’s financial interest in Genius Sports meant that every dollar spent on microbets, every new addict created through algorithmic targeting, every engagement spike from push notifications directly benefited the league’s portfolio.
The NFL received substantial revenue from its equity stake in Genius Sports and from its licensing agreements with sportsbooks. Even more concerning, the NFL’s shareholder control over Genius Sports meant it had both the ability and the incentive to influence the development of the betting infrastructure itself. Why would the league push back against addictive features or aggressive targeting if those same features were driving stock appreciation? This creates what economists call a “perverse incentive structure”—a financial arrangement where corporate profit is maximized by the behavior that causes the most consumer harm. As of March 2026, the NFL reduced its stake to become the second-largest shareholder, potentially reflecting growing awareness of reputational risk from association with gambling addiction litigation, but the financial incentives remain largely aligned.
How Rapidly Has the Sports Betting Market Expanded, and What Are the Regulatory Gaps?
The sports betting market has experienced explosive growth, expanding from $430 million in 2018 to $16.96 billion in 2025—a nearly 40-fold increase in just seven years. This rapid expansion has far outpaced the development of consumer protection frameworks and regulatory capacity. Pennsylvania alone generated $775 million in sportsbook revenue in the fiscal year from July 2024 to June 2025, derived from $8.7 billion in total wagers, with $8.2 billion of those wagers made online (rather than at physical locations).
These numbers illustrate the scale of capital flowing through these platforms and the corresponding volume of vulnerable consumers being exposed to addictive features. The regulatory challenge is compounded by the fact that most state-level gambling regulation was developed before microbetting and AI-driven targeting existed. Regulators implemented responsible gambling measures like self-exclusion programs and limits on promotional contact, but these protections are frequently circumvented by determined platforms and VIP hosts operating in gray areas. The lawsuit essentially argues that the regulatory framework has been outpaced by industry innovation, and that only private litigation can create sufficient accountability.
What Is the Potential Impact of This Case on the Industry?
This lawsuit, filed in Pennsylvania but backed by the Public Health Advocacy Institute, represents the beginning of what could become a significant shift in how gambling platforms are held accountable. If the plaintiffs succeed on design defect claims, the decision could fundamentally reshape the business model of microbetting—requiring platforms to implement technological guardrails that actually prevent addiction rather than exploit it.
This could include hard limits on daily betting frequency, mandatory cooling-off periods between bets, and prohibitions on targeted marketing to at-risk users. The case also has potential to expose the NFL’s financial incentives in gambling expansion to greater public scrutiny, potentially leading to changes in how professional sports leagues approach partnerships with betting companies. Congressional attention to sports gambling regulation has been increasing, and a high-profile class action victory could accelerate regulatory reform at the federal level.
Conclusion
The lawsuit targeting DraftKings, FanDuel, Genius Sports, and the NFL represents a critical moment in the regulation of online sports gambling. Two Pennsylvania residents have already lost nearly $2 million combined to platforms they allege were deliberately engineered to addict them, despite one plaintiff’s explicit request for self-exclusion. The case raises fundamental questions about whether an industry that has grown from $430 million to nearly $17 billion in less than a decade can be permitted to continue using AI, algorithmic targeting, and VIP host programs to maximize engagement with vulnerable populations.
If you have suffered significant gambling losses on DraftKings, FanDuel, or other platforms and believe you were targeted by aggressive marketing despite showing signs of addiction, you may have legal options. Class action litigation is a potential path to recovery, and multiple law firms are investigating claims related to predatory gambling practices. Consult with an attorney who specializes in consumer protection or class action law to understand your rights and potential remedies.
