Kalshi referred 32 cases of suspected insider trading to the Commodity Futures Trading Commission during the three months ending in June, highlighting the prediction market platform’s growing focus on market surveillance.
The CFTC-registered exchange opened more than 200 investigations during the first half of 2026. The reviews examined trading activity that may have involved material non-public information.
Kalshi uses internal monitoring systems, third-party vendor tools, trading-pattern analysis, and open-source intelligence to identify potentially improper activity. The platform can freeze accounts while investigations are underway and refer suspicious cases to federal regulators.
The exchange has previously imposed penalties for misconduct. In one 2025 case, a political candidate received a $2,246.36 fine and a five-year trading suspension for betting on their own race. Another trader was fined $20,397.58 and suspended for two years over activity involving a contract linked to YouTube.
Kalshi is also planning additional disclosure requirements for markets considered particularly vulnerable to insider information. Under the proposal, users participating in certain high-risk markets would be required to disclose their employers.
The measures follow recommendations from Kalshi’s advisory committee and come as regulators sharpen their focus on prediction-market conduct. In February, the CFTC issued an advisory reaffirming its authority over activity on registered prediction-market platforms and warning that misconduct can violate the Commodity Exchange Act.
The referrals demonstrate how Kalshi is using its status as a regulated designated contract market to distinguish itself from offshore and crypto-native competitors. The CFTC has not publicly indicated how many of the 32 referred cases it plans to pursue.
