The Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) are investigating former U.S. Rep. George Santos for alleged insider trading on the prediction market platform Kalshi. The investigation stems from suspicious trades Santos allegedly made regarding his attendance at President Donald Trump’s State of the Union address in February 2026.
Part 1: Immediate Action & Core Facts
Kalshi detected and flagged trades linked to Santos, freezing his account and referring the matter to federal regulators. The platform reported that Santos had publicly stated he would attend the State of the Union but later claimed he was stuck at an airport, causing the odds of his attendance to plummet. Sources familiar with the investigation say Santos had already placed bets against his own attendance, potentially profiting tens of thousands of dollars.
Santos has neither confirmed nor denied having a Kalshi account. He told NPR he was unaware of any investigation. The DOJ and CFTC have not publicly commented on the matter.
Part 2: Deeper Dive & Context
Background on the Investigation
Kalshi, a regulated prediction market, allows users to bet on various events, including political attendance. The platform’s internal systems flagged Santos’ trades as suspicious due to the timing and outcome of his bets. The CFTC, which oversees such markets, is examining whether Santos engaged in insider trading by manipulating the odds.
Santos’ Legal History
Santos, a former New York Republican, was expelled from Congress in 2023 after pleading guilty to federal fraud and identity theft charges. He served a seven-year sentence before President Trump commuted his term in October 2025. His legal troubles have continued, with this latest investigation adding to his ongoing scrutiny.
Broader Implications
Prediction markets like Kalshi and Polymarket have grown in popularity, raising regulatory concerns about insider trading and market manipulation. The CFTC has previously pursued cases involving similar platforms, including one involving a special forces soldier betting on geopolitical events.
Public and Political Reactions
Social media users accused Santos of running a scheme after his sudden change in plans for the State of the Union. Santos later addressed the controversy on his podcast, acknowledging that some traders lost money but downplaying the significance of the event.
Regulatory Oversight
The CFTC has vowed to crack down on insider trading in prediction markets, signaling heightened scrutiny of these platforms. The outcome of the Santos investigation could set a precedent for future enforcement actions.
