Key Takeaways:
George Santos is under investigation by the Justice Department and Commodity Futures Trading Commission for alleged insider trading on Kalshi, as nine House Democrats push the FTC to probe whether prediction market platforms mislead consumers.
The CFTC and DOJ are investigating whether the former New York congressman illegally bet against his own attendance at President Donald Trump's State of the Union address on Feb. 24, according to two people familiar with the probes who spoke on condition of anonymity. Kalshi detected the suspicious trades and referred the matter to law enforcement, one of the people said.
Santos publicly announced on X that he planned to attend the speech, then failed to appear, blaming a delayed flight. He had already placed bets on Kalshi that he would not attend, allowing him to profit tens of thousands of dollars, NPR reported. "I think it's fun and you can make a little money and you can have fun with it, but just understand that there will always be advantaged players in this game," Santos said on his podcast in March.
The probes mark the latest legal challenge for Santos, who pleaded guilty to wire fraud and aggravated identity theft in 2024 and was sentenced to more than seven years in prison. Trump commuted his sentence in October 2025 after he served 84 days. Polymarket, a rival prediction platform that had employed Santos as an influencer, said it was terminating his contract following the revelations.
On June 3, nine Democratic lawmakers led by Representatives Kevin Mullin and Gabe Vasquez sent a letter to the Federal Trade Commission urging an investigation into whether Polymarket, Kalshi, and similar platforms are misleading consumers by advertising as gambling sites while telling regulators they offer financial investment products. "These prediction market companies are presenting themselves differently to regulators than they are to the public, and that kind of contradictory messaging can mislead consumers about what rules and protections actually apply," Mullin said in a statement. The FTC has been asked to respond by June 29.
The congressional pressure follows a broader crackdown on prediction markets. In May, the House launched a probe into how Polymarket and Kalshi handle insider trading after a US Army soldier was accused of using classified information to profit on Venezuela-related contracts. Kalshi has also fined and suspended three political candidates for betting on their own elections. Critics have raised alarms about markets tied to conflict and regime change, including wagers on Iran, as lawmakers debate whether the industry can police itself.
The outcome of the FTC review could reshape the regulatory landscape for prediction markets, which have emerged as a significant use case for blockchain-based settlement. Platforms like Polymarket rely on crypto rails and stablecoins for transactions, and trading volumes hit record highs in March amid growing interest in political and geopolitical event contracts. If the FTC finds deceptive practices, it could impose penalties or force changes to how these platforms market themselves, potentially dampening user growth and trading activity.
