Former congressman George Santos has agreed to pay $35,000 to settle charges brought by the Commodity Futures Trading Commission over trades on the prediction market platform Kalshi. Regulators said the case involved alleged manipulative activity tied to contracts about whether Santos would attend the State of the Union address.

The settlement puts new attention on how U.S. regulators are policing prediction markets, especially when trading revolves around political events and public figures. In this case, the CFTC said Santos's trading activity crossed the line into market manipulation, leading to the financial penalty.

Kalshi offers event-based contracts that let users trade on the outcome of real-world developments. The matter involving Santos centered on a highly specific political question — his potential attendance at the State of the Union — and shows how closely regulators may scrutinize markets where a trader has a direct connection to the event being wagered on.

The case adds to the list of legal and regulatory issues surrounding Santos since leaving Congress. While the available details are limited, the settlement makes clear that federal authorities viewed the trades as serious enough to warrant enforcement action and a monetary payment.
