One of the largest brands in US sports betting, Caesars Entertainment, has been directly targeted by New York's Cayuga Nation in their dispute over mobile gaming on tribal grounds.
The Nation filed a federal lawsuit in the Northern District of New York on Tuesday, June 16, accusing American Wagering, Inc., doing business as Caesars Sportsbook, of accepting online sports wagers from residents of the Cayuga reservation without the consent of the tribe, a gaming compact, or federal supervision.
According to gambling lawyer Daniel Wallach, this is the first instance of a tribe suing a state-licensed sportsbook for internet wagers purportedly made from Indian territories.
Where Is a Bet Placed?
The central problem in the lawsuit is the location of an online wager, which has caused disagreements between tribes, authorities, and gambling companies nationwide.
Regardless of the location of the operator's servers, the Cayuga Nation claims that if a gambler is standing on tribal grounds when placing the wager, the game is taking place on its lands.
The case claims that between January 8, 2022, when New York's mobile betting market opened, to July 15, 2025, Caesars collected bets from within the reservation.
Because Class III gambling on Indian grounds typically needs a tribal gaming law and a federally recognized tribal-state agreement, the Nation claims the wagers violated the Indian gambling Regulatory Act (IGRA).
The tribe says it has a federally approved Class II gaming ordinance, but no compact with New York authorizing Class III gaming, such as sports betting. The complaint argues that means no sportsbook — state-licensed or otherwise — can legally take mobile sports bets from within the reservation unless the Nation has authorized it.
The Nation operates LakeSide Entertainment, a network of Class II gaming facilities in the Finger Lakes region.
The lawsuit also claims Caesars broke the law by marketing its sportsbook as available across New York without warning users that tribal lands were allegedly off-limits. The Nation says that created the misleading impression the platform could be used everywhere in the state.
Tribal Rights
Cayuga Nation leader Clint Halftown presented the case as a sovereignty issue in a statement to the Finger Lakes Daily News.
“Sovereignty means the right to regulate and protect our own lands and our people,” Halftown said.
On June 20, 2025, the Nation claims to have issued Caesars a cease-and-desist letter. According to the complaint, Caesars later consented to utilize geofencing to prevent bets from entering the reservation, but they refused to give a complete accounting of their previous betting activity and earnings.
In addition to a determination that Caesars' mobile sportsbook could not legitimately operate on Cayuga grounds without the Nation's consent, the action requests damages and an accounting of the money purportedly made from those wagers.
The case comes after the Nation filed a similar lawsuit against gaming officials in New York about lottery sales and the Jackpocket app on reservation property.
