Kalshi issues first lifetime ban for Republican politician over insider bets
The prediction platform permanently banned George Santos and issued a three-year suspension for Laurie Buckhout after investigations into using insider information on event contracts.
Prediction market platform Kalshi announced action against US House of Representatives candidate Laurie Buckhout and ousted Republican lawmaker George Santos over using insider information for trading on event contracts, in one of the first lifetime bans the company has imposed since its launch in 2021.
In separate notices of settlement of disciplinary action announced on Friday, Kalshi’s compliance department said it had permanently suspended Santos from trading on the prediction markets platform and imposed a $71,356 penalty. Buckhout received a three-year suspension and a $2,590 penalty.
Both restrictions by Kalshi were made in response to investigations into Santos and Buckhout trading using event contracts that could be manipulated by their own actions. According to the platform, Buckhout, running in North Carolina’s 1st congressional district, “announced her candidacy for public office and was added as a market option for a contract on a North Carolina Congressional election,” while Santos “engaged in trading activity in certain markets related to his attendance at the State of the Union address” in February 2026.
