Oklahoma Tribe Sues Kalshi Over Disputed Prediction Market Contract

The Alabama-Quassarte Tribal Town and Chief Samuel Marshall Jr. have sued Kalshi, company CEO Tarek Mansour, and tribal members Wilson Yargee and Michael Stopp.

The lawsuit alleges that Wilson Yargee was acting as chief inappropriately despite being removed from office in 2021. The legal action, filed in Muscogee (Creek) Nation District Court, seeks to declare that the tribe isn’t bound to the contract and that Yargee had no authority to enter into the deal. Further allegations include Yargee continuing to represent himself as the tribal town’s chief.

The tribe is seeking a temporary restraining order, compensation for damages, and correction to the defendants’ claims. Yargee continues to say he is the rightful tribal chief, according to reports, and has said he won reelection in 2025. The Bureau of Indian Affairs lists both Marshall and Yargee as chief. The Alabama-Quassarte Tribal Town is located about 90 miles southeast of Oklahoma City in Wetumka.
