Kalshi has permanently banned George Santos from its prediction market platform after the former New York lawmaker failed to cooperate with the company's investigation into allegedly unlawful trades he made related to his attendance at the 2026 State of the Union address. A Kalshi spokesperson said Santos is being banned due to "his lack of cooperation" with its compliance department, which established "reasonable cause" to believe he had engaged in insider trading over his attendance at the address. Santos is the first person to receive a lifetime ban, the spokesperson confirmed. The prediction market also penalized him $71,356, a filing on the company's website shows.
