Kalshi’s compliance department uncovered a series of large trades made by Santos throughout February 2026 involving contracts that would pay out based on whether he attended the State of the Union address on 24 February.
The exchange reported that Santos then issued public statements regarding his attendance, some deemed false or misleading, that were deliberately aimed at influencing the price of “Yes” or “No” contracts connected to his attendance.
Kalshi stated that these statements successfully moved market prices and that Santos realised profits totalling $17,839.57 from the trades. After detecting Santos’ trades, Kalshi froze his account then referred the matter to federal authorities, NPR reported.
