In a dramatic legal confrontation, an Illinois resident has taken aim at a prominent online gambling company, alleging its operations have contributed to significant personal and financial harm. On November 19, 2025, Mark T. Lavery filed a complaint in the United States District Court for the Northern District of Illinois against Kalshi Inc., accusing the Delaware corporation of facilitating illegal gambling activities that span multiple states.
The case unfolds with Lavery recounting his personal tragedy and the broader implications of Kalshi’s business practices. A self-described bounty hunter, Lavery has dedicated himself to holding gambling operators accountable after his wife’s suicide in 2008, which he attributes to her addiction to online gambling platforms like Ultimate Bet. He argues that these platforms were part of a criminal network involving high-profile figures such as Daniel Negreanu, who is now allegedly associated with Kalshi as a promoter. Lavery claims this connection gives him standing to seek penalties under various state laws.
Lavery’s complaint asserts that Kalshi conducts continuous gambling operations accessible to residents in Illinois, Ohio, Kentucky, and Massachusetts without appropriate geofencing measures. He alleges that every loss incurred by gamblers on Kalshi’s platform is subject to state penalties due to its unlicensed status in these regions. Citing Marvin v. Trout (1905), Lavery argues for his right to act as a private enforcer seeking statutory penalties rather than compensatory damages.
Central to Lavery’s case is testimony from former Kalshi employee Adhi Rajaprabhakaran, who describes the company’s operations as extracting value from losing gamblers—a process he terms “fish flow.” This description aligns with Lavery’s assertion that Kalshi profits not merely from fees but as a gambling “winner,” akin to other well-known platforms like DraftKings.
Lavery seeks judgment for statutory penalties under the Loss Recovery Acts of Illinois, Ohio, Kentucky, and Massachusetts. He emphasizes that these penalties are warranted due to the systematic transfer of wealth from recreational bettors—deemed “fish”—to Kalshi. His filing underscores the potential discovery of numerous additional victims whose losses remain within Kalshi’s control but are made plausible by Rajaprabhakaran’s revelations.
Representing himself pro se, Mark T. Lavery is challenging what he perceives as an opaque and exploitative industry practice through this lawsuit (Case ID: 1:25-cv-14184). The outcome could set significant precedents regarding accountability and consumer protection in online gambling operations.
