The Cayuga Nation, a federally recognized tribe in New York, has filed a federal lawsuit against Caesars Sportsbook, accusing the operator of illegally accepting mobile sports wagers placed within the tribe’s reservation.
The complaint was filed June 16 in the U.S. District Court for the Northern District of New York.
What the Tribe Is Alleging
Under the Indian Gaming Regulatory Act (IGRA), Class III gaming on tribal lands can only be conducted under an approved tribal-state compact. The Cayuga Nation does not have such a compact.
The tribe says Caesars accepted sports bets from users physically located on its 64,015-acre reservation between January 2022 and July 2025. It argues this made every one of those wagers unlawful.
The Cayuga Nation sent Caesars a cease-and-desist letter in June 2025. Caesars agreed to geofence the reservation in July 2025.
In September 2025, the tribe asked Caesars to provide an accounting of all wagers and revenues from the reservation. Caesars declined.
Cayuga Nation representative Clint Halftown said Caesars had “illegally encroached on our sovereign rights” by operating within the reservation without authorization.
The tribe is asking the court for declaratory relief, damages, disgorgement of profits, and a full revenue accounting.
Other mobile sportsbooks, including FanDuel and DraftKings, voluntarily geofenced the reservation after the tribe contacted them in 2025.
Connection to Prediction Market Disputes
The lawsuit goes beyond the Caesars dispute. Parts of the complaint echo arguments tribal gaming interests have raised against prediction market platforms like Kalshi.
The filing references 18-year-old bettors placing wagers without state or tribal oversight. That language stands out because New York’s licensed sportsbooks, including Caesars, require users to be at least 21. Prediction market platforms, by contrast, allow users as young as 18.
The complaint explicitly cites Ho-Chunk Nation v. Kalshi, a Wisconsin case in which a federal judge allowed a tribe’s IGRA claims against Kalshi to proceed in May 2026.
The Cayuga Nation uses this ruling to argue that IGRA gives tribes the legal power to challenge unauthorized gaming activity on their lands — a theory that could apply to both sportsbooks and prediction markets.
No prediction market operator is named as a defendant in the current case.
The complaint also includes a false-advertising claim under the Lanham Act. The tribe says Caesars misled bettors by advertising its sportsbook as available across all of New York without disclosing that it could not legally operate on the Cayuga reservation.
A separate but related lawsuit filed by the Cayuga Nation against the New York State Gaming Commission was allowed to proceed last year. That case alleged the state was conducting unauthorized lottery operations on reservation land without a tribal-state compact.
