The Cayuga Nation has filed a federal lawsuit against Caesars Entertainment, alleging the sportsbook accepted mobile wagers from bettors located on the Nation’s reservation without tribal authorization.
The lawsuit argues that Caesars conducted Class III gaming activity on the Cayuga Nation’s reservation without obtaining the approvals required under the Indian Gaming Regulatory Act (IGRA). According to the complaint, the sportsbook accepted mobile bets from individuals who were physically located on tribal lands through its state-licensed platform, despite lacking a tribal-state compact or federal authorization to do so.
The Cayuga Nation contends that IGRA grants federally recognized tribes primary authority over gaming conducted on their reservations. By accepting wagers from within reservation boundaries without tribal consent, the complaint alleges Caesars bypassed the regulatory framework established under federal law. It also states that Caesars undermined the Cayuga Nation’s exclusive authority to oversee gaming on its lands.
In addition to seeking legal relief, the Cayuga Nation argues that the alleged conduct deprived it of economic opportunities and governmental authority that Congress intended tribal nations to retain through IGRA.
According to the complaint, the Cayuga Nation alleges that Caesars accepted mobile sports wagers from within reservation boundaries from January 2022 through July 2025. The lawsuit also accuses the operator of misleading consumers by marketing its mobile sportsbook as being legal throughout New York, despite the Cayuga Nation’s position that betting on its reservation required tribal authorization.
Court filings state that the Cayuga Nation formally notified Caesars of its concerns in June 2025 through a cease-and-desist letter. The complaint says Caesars later implemented geofencing technology designed to block users located on reservation lands from placing wagers through its platform.
With that said, the Cayuga Nation claims Caesars did not comply with its request to disclose the volume of bets accepted or the revenue generated from these bets that allegedly occurred within the reservation before the geofencing restrictions were implemented.
The lawsuit has the potential to extend beyond Caesars, as it could test how federal courts interpret tribal sovereignty in relation to mobile sports betting.
At the center of the dispute is whether a mobile wager is legally deemed to occur where the bettor is physically located or where the sportsbook processes the bet. The Cayuga Nation argues that bets placed by users located on its reservation fall under tribal jurisdiction, even if they are accepted through New York’s statewide mobile betting system.
If the court sides with the Cayuga Nation, licensed sportsbooks operating in New York may face increased pressure to ensure their geofencing systems exclude tribal lands unless they have the necessary agreements with the affected tribes. Operators could also encounter additional legal challenges from other tribal nations with similar concerns.
For Caesars specifically, the case could result in financial liability if the court determines the operator violated IGRA. The Cayuga Nation is seeking damages and other legal remedies, including an accounting of wagering activity that allegedly took place on its reservation before geofencing measures were put in place.
Regardless of the outcome, the lawsuit could become an important case for defining how tribal gaming rights apply to mobile sports betting.
