Public Health Institute files lawsuit against major sportsbooks
The Public Health Advocacy Institute has launched a lawsuit against several US sportsbook operators, including DraftKings, FanDuel and Genius Sports, as well as the NFL.
The non-profit argues that online sportsbooks are engineered to encourage addictive behavior and that the named defendants are distributing and profiting from them.
According to the complaint, filed in Pennsylvania, the platforms rely heavily on advanced technologies, such as artificial intelligence, to keep users engaged and increase betting frequency.
One of the main focuses of the lawsuit is on “micro-betting”, which refers to in-play betting that these sportsbooks offer, where users can place multiple bets in seconds while watching a sporting event.
The complaint alleges that the two plaintiffs, both Pennsylvania residents, signed up for DraftKings and FanDuel, which use real-time data supplied by betting technology company Genius Sports. According to the suit, both were lured by DraftKings and FanDuel into placing micro-bets on its platforms.
It also mentions the NFL’s partnership with Genius Sports, arguing that both defendants profited from increased micro-betting.
Public Health Advocacy Institute Litigation Director Andrew Rainer said, “Following in the footsteps of the tobacco industry, the online sports gambling industry has developed a highly addictive, difficult-to-resist product that bombards consumers with dozens of betting opportunities every minute of the day and that is leaving a trail of devastated victims.”
Last week, DraftKings was sued by the NCAA for using its March Madness brand on its platforms.

The Backstory
Why this public health lawsuit landed now
The complaint by the Public Health Advocacy Institute against DraftKings, FanDuel, Genius Sports and the NFL reflects a broader backlash against products that compress wagering into rapid, AI-optimized prompts designed to keep users betting. That tension has been building for more than a year as lawmakers, regulators and health advocates test where sports entertainment ends and addictive design begins. The plaintiffs’ focus on micro-betting and real-time data feeds ties the case to a widening policy debate over whether the mechanics of modern betting — instant markets, personalized offers and predictive models — demand new consumer safeguards. It also arrives as college and pro leagues deepen data partnerships that fuel in-play markets, and as alternative “prediction” platforms push into the mainstream while insisting they operate outside state gambling regimes.
Micro-bets move to the center of the fight
At the core of the filing is the claim that in-play micro-betting, powered by rapid data and algorithmic prompts, accelerates wagering frequency and risk. That critique has been sharpened by a recent industry pivot toward bite-size markets on the next play, pitch or possession — and by the use of behavioral nudges and personalized offers to increase engagement. Public health advocates have warned that the design of these products, not just their subject matter, is the issue. The stakes grew as leagues and data suppliers expanded the volume and velocity of in-game feeds that underwrite those markets. The plaintiffs’ emphasis on Genius Sports’ role underscores how data pipelines, licensing deals and team or league equity stakes can link on-field events to high-frequency wagering mechanics in ways that complicate traditional consumer-protection frameworks.
College data deals draw fire from health advocates
Scrutiny intensified after the NCAA struck an agreement with Genius Sports to sell real-time college data to the betting industry. The Public Health Advocacy Institute publicly criticized that pact as an engine for AI-enabled micro-betting on student-athlete performances, arguing it would expand high-intensity wagering and related harms. Advocates said the NCAA framed the revenue as funding education programs while underplaying addiction risks tied to a surge of granular, in-game markets. The dispute, outlined in the Institute’s criticism of the NCAA–Genius Sports data sale, also raised transparency questions given the NFL’s financial interest in Genius. That episode previewed the legal theory now central to the new lawsuit: when organizations monetize real-time data that enables continuous micro-bets, they help distribute a product whose design is inherently addictive and thus should face heightened accountability.
States tighten definitions of illegal betting
Regulatory pressure has not been limited to sportsbooks. In California, consumer law firms filed class actions alleging that popular daily fantasy providers operate illegal sports betting under the guise of fantasy contests. The complaints, aimed at industry leaders and several smaller entrants, seek monetary and injunctive relief and argue the companies violated state penal law. Within days, Attorney General Rob Bonta issued a formal opinion concluding certain daily fantasy formats are illegal gambling in the state, a move that could reshape the market and embolden additional litigation. The push is detailed in lawsuits targeting daily fantasy operators in California’s DFS crackdown. For the public health lawsuit now in Pennsylvania, California’s posture offers a template for regulators and plaintiffs to reframe game design — not labels — as the determinant of legality.
Prediction markets test federal preemption claims
At the same time, prediction platforms regulated by the Commodity Futures Trading Commission have grown rapidly while clashing with state authorities over jurisdiction. Kalshi, which offers federally regulated event contracts it characterizes as financial instruments rather than wagers, has sued states that sought to shut it down under gambling law. The platform has moved for injunctions while arguing that state actions are preempted by the federal derivatives regime. Recent cases include Kalshi’s suit against Utah officials after leaders signaled a crackdown despite the platform’s CFTC designation, as described in the company’s preemptive Utah filing. Kalshi has also challenged a cease-and-desist from Maryland’s lottery regulator, asserting its contracts are peer-to-peer swaps outside state gambling oversight, in its Maryland lawsuit. The company previously won temporary relief in Nevada and Tennessee, sharpening a federal-versus-state contest that may shape how fast, granular event markets are regulated.
Surging downloads, shifting consumer behavior
That legal backdrop coincides with a notable shift in consumer interest. Heading into the Super Bowl, Kalshi’s app downloads reportedly topped three million in January, eclipsing monthly installs for leading sportsbooks. The surge, highlighted in coverage of Kalshi’s download gains, points to rising demand for event-driven trading products that promise legal availability across most states without a patchwork of licenses. Although prediction markets differ from traditional sportsbooks, both thrive on real-time data and micro-outcomes around major events. That convergence is central to public health concerns: as platforms across categories race to offer faster, narrower wagers or contracts, the behavioral design risks — frequency, immediacy and personalized prompts — become common threads regardless of regulatory label.
Leagues, data suppliers and the path ahead
The new suit’s inclusion of Genius Sports and the NFL signals how liability debates could expand beyond operators. Data providers that enable split-second pricing and leagues with equity or commercial ties may face closer scrutiny over whether they helped create conditions for high-intensity wagering, especially where student or amateur sports are involved. Prior controversies over the NCAA’s data sale, clashes over daily fantasy formats in California and state challenges to prediction markets have all moved the industry toward a reckoning on design, not just access. If courts accept arguments that micro-betting and gamified prompts constitute an addictive product akin to prior public health battles, operators and their data partners may need to overhaul how in-play markets are packaged and promoted — or risk stricter rules limiting speed, frequency and personalization. The Pennsylvania case will test that theory, with potential ripple effects for league partnerships, data monetization and the business models underpinning real-time betting across sports and prediction markets.
