Prediction market platform Kalshi has permanently banned former Congressman George Santos from trading, marking the company’s first lifetime ban and a significant enforcement action against insider trading in the emerging sector. The disciplinary action, announced August 31, 2026, followed Santos’s failure to cooperate with Kalshi’s compliance investigation into bets he placed on his own attendance at President Donald Trump’s State of the Union address in February 2026.
Kalshi imposed a financial penalty of $71,356 on Santos, according to a disciplinary filing posted on the company’s website. The platform’s compliance department found that Santos netted nearly $18,000 in profits from the bets while making false statements on social media to benefit his wagers, according to reports citing the company’s investigation.
This enforcement represents the second major action against Santos in recent months. In July 2026, the Commodity Futures Trading Commission, the federal regulator that oversees prediction markets, announced that Santos had agreed to pay $35,000 to settle a federal investigation into the same trades. The CFTC also imposed a three-year trading ban on the former lawmaker, according to reporting from CNBC and other outlets.
Santos, who represented New York’s 3rd District before being expelled from the House in 2023 on fraud and campaign finance charges, had publicly stated on social media that he planned to attend the State of the Union address. Kalshi’s investigation found that he simultaneously placed bets on the prediction market predicting he would not attend—a potential case of using nonpublic knowledge of his own actions to profit from the wager.
Insider trading prohibitions in prediction markets remain an emerging area of enforcement. Federal law and CFTC regulations classify prediction market contracts as swaps and prohibit trading on material nonpublic information, just as they do in traditional securities and commodities markets. Kalshi’s rules explicitly ban insider trading and warn that violations can lead to suspension or removal from the platform. The Santos case illustrates how prediction market platforms are beginning to police such conduct actively, using compliance investigations and regulatory referrals to detect suspicious trading patterns.
The action against Santos follows similar enforcement against other government insiders. Kalshi previously took action against Gabriel Perez, a former White House teleprompter operator, for prediction market trading violations, highlighting growing scrutiny of how public officials and government employees use access to nonpublic information. As prediction markets face lawsuits from red and blue states over regulatory authority, enforcement actions like the Santos ban underscore the platforms’ efforts to maintain market integrity and comply with federal oversight.
Santos denied wrongdoing in his settlement statement, asserting that he never intended to deceive anyone or manipulate the market and that he settled with the CFTC to avoid prolonged litigation. Kalshi’s additional lifetime ban, however, reflects the platform’s conclusion that his lack of cooperation with its compliance investigation warranted the most severe penalty available.
