Cayuga Nation sues Caesars Sportsbook over mobile bets placed on New York tribal lands

The Cayuga Nation has filed what it says is the first lawsuit of its kind against a state-licensed sportsbook, accusing American Wagering, Inc., the operator of Caesars Sportsbook, of taking mobile wagers inside its New York reservation without authorisation. For high-risk operators, the point is obvious: if geolocation and tribal boundaries do not line up, the liability does not disappear just because the book is licensed by the state.

1. The complaint was filed in federal court and says Caesars accepted mobile sports bets from within the Cayuga Nation’s 64,000-acre reservation between January 2022 and July 2025, even though there was no tribal-state gaming compact between the Nation and New York. The Nation says that conduct violated the Indian Gaming Regulatory Act (IGRA).
2. In the filing, the Nation argues that Caesars operated “under color of state law” inside tribal territory without the Nation’s authorisation, without a Tribal-State compact, and without oversight by the National Indian Gaming Commission (NIGC) or the Secretary of the Interior. The lawsuit says that deprived the Nation of the governmental and economic benefits IGRA was meant to secure.
3. The complaint also includes a federal Lanham Act claim, alleging that Caesars marketed its mobile sportsbook as available across New York without disclosing that operations may be restricted on tribal lands. That is the sort of disclosure issue that can turn a geolocation problem into an advertising problem too.
4. According to the filing, the Nation sent Caesars a cease-and-desist letter on June 20, 2025, ordering it to stop all gaming activity on the reservation. A month later, Caesars agreed to use geofencing to block wagers from reservation territory.
5. On September 2, 2025, the Nation asked Caesars for a full accounting of gaming activity on the reservation, including all wagers accepted and revenues derived from them, with a response due by September 19, 2025. Caesars said it had agreed to geofence its operations out of the reservation but refused to provide an accounting of the proceeds generated there.

The Nation is seeking a declaratory judgment that Caesars’ mobile betting operations on tribal lands were illegal and unauthorised, plus damages and a full accounting of all revenue from wagers placed within the reservation. For PSPs, sportsbook operators, and acquirers, this is a reminder that “licensed in the state” is not the same thing as “cleared for every square mile in the state.”
