DraftKings, FanDuel, the NFL, and Genius Sports are facing a new lawsuit in Pennsylvania that claims modern sportsbook apps were deliberately built to keep users wagering through rapid-fire live bets. The complaint, filed March 24 on behalf of Pennsylvania bettors Christopher Sage and Terry Thompson, argues that in-game microbetting has turned legal sports betting into a product that disregards traditional safegaurds.
The case frames live microbetting itself as the core problem, arguing that the structure of the betting experience, not just the way it is advertised, goes against responsible gambling practices. That puts one of the fastest-growing parts of the U.S. sportsbook model under a magnifying glass.
Plaintiffs say nonstop in-play bets kept them inside a constant loop
At the center of the complaint is the argument that microbets compress sports wagering into a near-continuous cycle. Instead of waiting for a game result, users can keep betting on the next play, pitch, throw, or drive, with outcomes resolving in seconds or minutes and new wagers appearing immediately after. The lawsuit says that pace removes the natural pauses that once limited how often people could bet.
The filing also says the two plaintiffs were pushed deeper into that cycle through direct VIP treatment. It alleges that sportsbook hosts stayed in personal contact with them, offered gifts and event trips, and continued outreach even as signs of harmful gambling became more visible. According to ESPN’s report on the complaint, the two men are alleged to have lost more than $2 million combined.
The complaint says official NFL data made large-scale microbetting possible
The lawsuit does not stop with the sportsbooks. It argues that the NFL and Genius Sports helped make the product possible by supplying the real-time data needed to offer and settle in-game microbets. The complaint says Genius is the exclusive supplier of NFL live data and that the league still holds a significant equity position in the company.
The plaintiff’s argue that microbetting is not just a sportsbook feature layered on top of sports, but a system supported by a broader commercial chain that includes leagues, data rights, and technology providers. The suit seeks damages, attorney fees, a jury trial, and court orders aimed at stopping the alleged conduct.
The case lands as lawmakers push back on microbetting’s pace and intensity
The lawsuit also arrives as microbetting faces growing pressure outside the courts. In New Jersey, Senate Bill S2160 would ban live microbets, defining them as proposition wagers on the next play or action and citing responsible gambling concerns. In New York, Assembly Bill A09343 would go further by directing regulators to prohibit in-play sports wagers altogether.
That does not mean the Pennsylvania case will reshape the market on its own. But it does show where the next fight is moving. The debate is no longer just about ads, promotions, or VIP programs. It is now about whether the design of microbets can itself become a legal and regulatory liability.
