Kalshi imposes lifetime trading ban on George Santos over State of the Union market
Regulation & Gov ·
The prediction-market operator barred the former congressman for good and fined him tens of thousands of dollars after concluding he manipulated a contract tied to his own appearance at the address.
Kalshi has permanently cut off George Santos from its platform, citing evidence that he manipulated a market wagering on whether he would attend the State of the Union, according to Decrypt. A compliance notice dated Aug. 28 describes a pattern of large trades Santos placed between Feb. 2 and Feb. 25 in a contract whose payout depended on his own attendance, an outcome he was positioned to influence.
Investigators concluded Santos followed those trades with a series of public remarks about his plans, some inaccurate or misleading, aimed at swinging the contract's price in his favor. The scheme worked well enough to net him $17,839.57, per the notice, close to the $18,000 figure widely cited for his gains. Kalshi's disciplinary unit said the conduct breached several rules at once: bans on manipulating prices, on trading positions where the trader can sway the result, and on using deceptive tactics to defraud counterparties. Santos was also faulted for not cooperating once the exchange started looking into the trades.
Beyond the trading ban itself, Kalshi levied a $71,356 penalty against him, according to reporting from The Block, and shut him out of the platform entirely, whether he tries to trade directly or through another account. The action is the first time Kalshi has permanently excluded someone who previously served in Congress, underscoring how the exchange treats conflicts of interest when a trader has direct control over the event being wagered on.
The case lands amid a broader run of integrity problems surfacing across event-contract platforms as trading volumes climb. Regulators have already penalized a former White House teleprompter operator for trading ahead of presidential remarks, a video editor lost a job over a separate Kalshi insider-trading review, and a soldier faces charges linked to Polymarket wagers. Kalshi has responded by adding new safeguards, though it has not detailed exactly how those measures would have caught a case like Santos's earlier.
Left open is whether Santos faces any consequence beyond the exchange-level ban and fine, and whether other lawmakers or public figures with markets tied to their own actions will draw similar scrutiny going forward.
