Former Congressman George Santos has agreed to a $35,000 settlement with the Commodity Futures Trading Commission (CFTC) following an investigation into his trading activities on the prediction marketplace Kalshi. The probe focused on his bets regarding his attendance at former President Donald Trump's State of the Union address. Santos did not admit wrongdoing, with his lawyer stating that the settlement was a practical resolution to avoid costly litigation.

The CFTC alleged that Santos manipulated a Kalshi prediction-market contract by trading on whether he would attend the February 2026 State of the Union address, while simultaneously making public statements that influenced the contract's price. The agency claims he generated over $17,500 in profits through this activity. For example, he allegedly held a "yes" position, then posted on X about what to wear, causing the price to rise, and later profited from closing the trade. The CFTC also stated that Santos posted updates about his travel to Washington by plane and train while trading both sides of the contract.

Under the settlement, Santos is required to return the profits earned, pay the remaining financial penalty, and is prohibited from violating federal derivatives rules. He also received a three-year ban from trading products overseen by the CFTC, which extends beyond prediction markets to include futures and other regulated derivatives. Kalshi has also permanently barred Santos from its platform.

This case is significant for prediction markets as it demonstrates how existing anti-manipulation rules can be applied to event contracts, especially when individuals can directly influence the outcome of the events being bet on. The CFTC views Santos' actions as willfully or recklessly using his control over information and events to benefit his trading positions. The settlement suggests that public statements, travel updates, and omitted information that affect prices for a trader's benefit could lead to regulatory scrutiny.

Santos' counsel argued that the trades were a response to changing travel plans due to winter weather, not an intent to deceive or manipulate the market, and that Santos cooperated with the investigation. However, the CFTC maintained that Santos knowingly used public communications and withheld information about his trading activity while benefiting from the resulting market movements. This action sets a precedent for how regulators may view trading by individuals who are the subject of prediction market contracts, particularly concerning political events.
