Legal proceedings initiated in Pennsylvania allege that major sports betting operators DraftKings, FanDuel, the National Football League, and Genius Sports deliberately engineered their online gambling platforms to push users into addiction through microbetting features.
The Public Health Advocacy Institute brought the legal action representing Christopher Sage and Terry Thompson. Both individuals assert they suffered from serious gambling problems after engaging with the mobile betting applications.
According to the legal filing, microbetting creates opportunities for users to place bets on an essentially unlimited number of in-game occurrences. Each individual play, throw, attempt, or moment transforms into a fresh betting chance as betting lines adjust instantaneously.
The complaint characterizes the applications as a “relentless, always-on addiction-amplifying machine.” The filing contends that operators have exploited mobile platforms and machine learning technologies to push users into nonstop wagering cycles.
Parallels Drawn Between Microbets and Casino Slot Games
The legal document establishes a clear connection between microbetting mechanics and traditional slot machine design. The filing contends that the rapid tempo and high volume of live proposition wagers replicate the quick-fire nature of slots, long recognized as one of the most psychologically addictive gambling formats.
According to the complaint, individual live proposition bets resolve within mere minutes or sometimes just seconds. The lawsuit characterizes this structure as one that provides “no off-ramps or pauses in the action.”
Both plaintiffs indicate they enjoyed sports viewing and placed sporadic wagers without incident for approximately two decades. Their betting patterns shifted dramatically once they began engaging with smartphone-based sportsbook applications.
“Within just a few years… Plaintiffs nearly lost everything—their money, their houses, their business, their families,” the filing states.
The legal action further alleges that betting platforms deploy VIP membership structures to maintain user engagement. The complaint states that company representatives stayed in regular communication with bettors and provided travel packages, merchandise, and special offers as enticements.
The lawsuit names the NFL and Genius Sports for providing the instantaneous sports data that enables microbetting functionality. According to the complaint, without access to this data stream, sportsbooks would be unable to offer these betting products.
In 2025, Genius Sports collected $126.1 million in fees from live in-game microbetting operations. This figure accounted for approximately 19% of the company’s overall annual revenue.
The NFL maintains a financial interest in Genius Sports. Both DraftKings and FanDuel have publicly stated that live wagering comprises around 50% of all bets placed through their systems.
Legislative Efforts to Limit Microbetting Expand
The lawsuit presents several allegations under Pennsylvania statutes, including defective product design, inadequate warning disclosure, negligent conduct, deceptive business practices, and deliberate infliction of psychological harm. Those bringing the suit are requesting financial compensation, a jury hearing, and court-ordered restrictions.
This marks another chapter in PHAI’s ongoing legal battles with sportsbook companies. The organization initiated a class-action case in Massachusetts during 2023 challenging DraftKings’ deposit incentive structures. Last month, a judge permitted that matter to advance toward class certification, evidence gathering, and courtroom proceedings.
During 2025, PHAI launched comparable litigation in Pennsylvania against Caesars Palace Online Casino regarding its promotional bonus offerings.
The legal challenge emerges amid heightened regulatory attention to microbetting across numerous jurisdictions. New Jersey legislators moved forward this week with proposed legislation to prohibit microbets. New York lawmakers have put forth legislation to eliminate live betting entirely.
Massachusetts, Colorado, Kentucky, Louisiana, and Minnesota are all evaluating possible restrictions on particular proposition wagers. Ohio, Maryland, and Vermont have already implemented prohibitions on proposition bets involving collegiate athletes.
