Federal regulators and the Justice Department have opened investigations into former U.S. Rep. George Santos over allegations that he placed bets on the prediction market platform Kalshi that were directly contradicted by his own public statements, sources familiar with the matter told ABC News and NPR. Kalshi detected the trading activity, froze Santos' account, and referred the matter to both the Commodity Futures Trading Commission and the Justice Department. Santos declined to confirm or deny having an account on the platform when asked by NPR.
According to sources, Santos wagered on Kalshi that he would not attend President Trump's 2026 State of the Union address while simultaneously posting on social media that he planned to be present in the gallery. He did not attend, and the market odds shifted in favor of his wager. Investigators are examining whether Santos profited by deliberately deceiving the public about his plans to influence the market — the same basic theory that underpinned two previous federal prosecutions against individuals who allegedly traded on Polymarket using non-public information.
Santos' Response and Legal History
Santos told NPR he was unaware of any investigation, and when asked whether he had a Kalshi account responded only, "I'm not saying yes, I'm not saying no." His evasive answer drew significant media attention and has been widely interpreted as an implicit acknowledgment that the account in question may indeed be his. Santos was expelled from the House of Representatives in December 2023 following an Ethics Committee investigation and later pleaded guilty to multiple federal fraud and identity theft charges stemming from his 2022 congressional campaign.
The Kalshi probe represents a new legal front for Santos, arising from conduct on a federally licensed prediction market platform. Kalshi operates under CFTC oversight as a designated contract market, which means its users are subject to federal commodity law. The platform's decision to self-report the suspicious trades to regulators reflects an increasingly proactive compliance posture among licensed prediction market operators, who face significant reputational and regulatory risk if they are seen as facilitating market manipulation.
Implications for Prediction Markets
The Santos investigation highlights a risk that prediction market critics have raised consistently: when public figures control information about their own actions and can also wager on the outcomes of those actions, the potential for insider trading is significant. Kalshi and platforms like it are regulated financial markets under federal law, and the CFTC has signaled it takes manipulation and insider trading on these platforms seriously.
For users of prediction market products, the case reinforces that these platforms operate under enforceable legal frameworks — not a regulatory gray zone. The CFTC will decide whether to bring formal enforcement action against Santos, a process that typically takes several months to complete. Whether the case results in criminal referral will depend on what investigators find about the nature and extent of Santos' trading activity. The broader prediction market industry is watching closely, as the outcome may influence how Congress approaches legislation currently pending that would either expand or restrict event contract trading in the United States.
