Former New York Representative George Santos is under federal investigation for alleged insider trading on the Kalshi prediction-market platform.
The probe examines whether the former lawmaker used nonpublic information to profit from bets regarding his own movements. Because prediction markets are increasingly used to forecast political events, this case could set a precedent for how the government regulates the intersection of political insider knowledge and financial speculation.
According to reports from early June 2026, the Department of Justice and the Commodity Futures Trading Commission are leading the investigation [1], [2]. The probe centers on trades flagged by Kalshi as suspicious. Specifically, investigators are looking into bets Santos allegedly placed on whether he would appear at President Trump’s State of the Union address in February [3], [4].
Two sources familiar with the matter provided details on the investigation [5]. The Commodity Futures Trading Commission generally oversees the legality of prediction contracts in the U.S. to ensure markets are not manipulated by those with unfair access to information.
Kalshi flagged the trades after noticing patterns that suggested the trader had inside knowledge of the event's outcome [6]. The investigation seeks to determine if Santos intentionally manipulated the market, or leveraged his position to secure a financial gain based on his planned attendance [1], [4].
Santos has faced numerous legal challenges since leaving office, but this investigation marks a shift toward his activities in the emerging digital assets and prediction market sector [2], [6]. Neither the DOJ nor the CFTC has issued a formal charge at this time.
“George Santos is under federal investigation for alleged insider trading on the Kalshi prediction-market platform.”
This investigation highlights a growing regulatory gap in the prediction-market industry. While traditional insider trading laws apply to stocks, the application of these rules to 'event contracts'—where individuals bet on real-world outcomes—is relatively new. If the DOJ successfully prosecutes a former official for betting on their own schedule, it may lead to stricter disclosure requirements for politicians using platforms like Kalshi.
