Prediction market company Kalshi permanently banned former Republican Rep. George Santos from its platform Monday and imposed a $71,356 penalty after determining that he manipulated contracts tied to his own attendance at President Donald Trump’s 2026 State of the Union address.

Kalshi alleged that Santos placed a series of wagers on whether he would attend the address and then made public statements about his plans to influence the price of the contracts. The trades ultimately netted Santos nearly $18,000, according to Kalshi and the Commodity Futures Trading Commission, the federal regulatory body overseeing prediction markets.
