Kalshi Bans Former Rep. George Santos for Life Over State of the Union Trades

Kalshi, a prediction-market platform, announced on Monday, August 31, 2026, that it had permanently banned former U.S. Rep. George Santos, a New York Republican whose congressional tenure was marked by widespread fabrications, from using its platform. The ban stems from trades Santos placed on markets predicting whether he would attend Donald Trump's State of the Union address earlier in 2026. Kalshi said its compliance department found reasonable cause to believe Santos engaged in insider trading by using non-public knowledge of his own attendance plans to place these bets. According to Kalshi, Santos profited approximately $17,839 from the trading activity in question. The company fined him $71,356 in connection with the violations and stated that he made barred trades and misleading public comments that influenced market prices. Kalshi also said Santos did not cooperate with its internal investigation into the matter. The company described this as the first lifetime ban it has issued against any user since the platform's founding. Santos's response to the ban and fine has not been detailed in available reporting, and it remains unclear whether he intends to contest Kalshi's findings or pay the fine. It is also unresolved whether any federal regulatory body is separately investigating the conduct beyond Kalshi's own compliance review, as some reports reference regulators' allegations while the primary action described is Kalshi's internal enforcement decision. No further legal proceedings or additional penalties have been confirmed at this time.
