Landmark Lawsuit Alleges Sports Betting Platforms Designed to Fuel Addiction, NFL Named as Defendant

Philadelphia, PA – A sweeping product liability lawsuit filed Wednesday alleges that online sports betting platforms, including DraftKings and FanDuel, are intentionally designed to foster addiction, and that the National Football League bears significant responsibility due to its substantial ownership stake in key data provider Genius Sports. The Public Health Advocacy Institute (PHAI) brought the suit in the Court of Common Pleas of Philadelphia County, Pennsylvania, naming DraftKings (NASDAQ: DKNG), FanDuel (owned by Flutter Entertainment plc, NASDAQ: FLUT), Genius Sports Ltd. (NYSE: GENI), and the NFL as defendants.

The lawsuit centers on the proliferation of “microbets” – rapid-fire wagers placed during live sporting events – and the technologies used to encourage their apply. PHAI contends these platforms employ artificial intelligence and machine learning to identify and exploit vulnerable individuals, maximizing betting frequency and ultimately leading to addiction. The complaint alleges a coordinated effort to transform casual sports fans into habitual gamblers.

Plaintiffs Detail Aggressive Tactics

The plaintiffs, Pennsylvania residents Christopher Sage and Terry Thompson, claim they were lured into increasingly frequent microbetting through aggressive marketing tactics employed by DraftKings and FanDuel. These tactics, according to the lawsuit, included constant push notifications promoting bets, and personalized outreach from “VIP Hosts” offering promotional deals, trips, and gifts – even after the plaintiffs expressed a desire to stop betting. The suit alleges these actions constitute negligence, intentional infliction of emotional distress, and violations of Pennsylvania’s Unfair Trade Practices and Consumer Protection Law.

NFL’s Financial Ties to Genius Sports Under Scrutiny

A central element of the lawsuit focuses on the NFL’s financial relationship with Genius Sports, the exclusive supplier of official NFL game and player data. The complaint details how the NFL was the largest shareholder in Genius Sports from 2021 to 2025 and remains the second-largest shareholder today. According to the NFL’s own website, Genius Sports “powers over 98% of the legalized U.S. Sports betting market with official NFL data,” driving innovations like player props and same-game parlays. This arrangement, PHAI argues, creates a direct financial incentive for the NFL to promote increased betting activity.

“The NFL is unique among sports leagues in that it not only earns money through advertising and sponsorships, but it is also an owner of a main player in the gambling ecosystem,” stated Mark Gottlieb, Executive Director at PHAI. “They profit the more people lose money through gambling.”

Gambling Addiction Recognized as a Serious Public Health Issue

The lawsuit underscores the growing recognition of gambling addiction as a serious public health concern. Both the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-V) and the World Health Organization (WHO) classify gambling addiction in the same category as addiction to substances like heroin, cocaine, and tobacco. This classification highlights the potential for severe harm associated with unchecked betting behavior.

The legal landscape surrounding sports gambling has dramatically shifted since the 2018 Supreme Court decision in Murphy v. National Collegiate Athletic Association, which allowed states to legalize gambling. Since then, the industry has experienced explosive growth. In Pennsylvania alone, sportsbooks generated nearly $775 million in revenue from over $8.7 billion in wagers between July 2024 and June 2025, with over 95% of that wagered online.

PHAI’s History of Challenging Industry Practices

The Public Health Advocacy Institute has a long history of litigating against industries whose products are deemed harmful to public health. The organization previously led successful litigation against tobacco companies in the 1990s, resulting in multibillion-dollar settlements. PHAI is currently involved in separate litigation against DraftKings regarding allegedly deceptive marketing practices related to “cash bonus” offers. A Massachusetts judge recently rejected most of DraftKings’ motion for summary judgment in that case, allowing the suit to proceed toward class certification.

PHAI Litigation Director Andrew Rainer framed the current lawsuit as a continuation of this operate, stating, “Following in the footsteps of the tobacco industry, the online sports gambling industry has developed a highly addictive, difficult-to-resist product…Instead of continuing to stuff their pockets with billions of dollars in annual revenues, the perpetrators of this devastation…must be held to account.”

What’s Next in the Case

The case, Sage and Thompson v. DraftKings, Inc. Et al. (No. 260303384), is currently pending in the Court of Common Pleas of Philadelphia County, Pennsylvania. The complaint is available for review on the PHAI website. The outcome of this case could have significant implications for the future of sports betting regulation and the responsibilities of leagues and platforms in protecting consumers from the risks of addiction.
