Platform Enforcement Action Follows Compliance Investigation
Regulated prediction market exchange Kalshi announced today that it has issued a permanent lifetime ban against former U.S. Congressman George Santos. The platform’s internal surveillance and risk mitigation division concluded that accounts associated with Santos engaged in improper trading activity utilizing non-public political information.

The action represents one of the highest-profile enforcement measures taken by a U.S. regulated event contract platform since political prediction markets gained mainstream financial volume.
Details of Irregular Trading Activity
According to compliance statements released by Kalshi, automated surveillance algorithms flagged unusual position sizes placed on specific congressional votes and political appointment outcomes shortly before public announcements were made. Further audit trails linked the trading activity directly to entities controlled by the disgraced former lawmaker.
Kalshi stated that all profits generated from the flagged transactions have been frozen pending further legal review and regulatory reporting.
Heightened Scrutiny on Political Prediction Markets
The ban underscores growing scrutiny surrounding political forecasting exchanges as regulators examine potential insider trading risks involving federal officials. CFTC officials and consumer protection groups continue to advocate for rigorous transparency standards and strict prohibition enforcement across all event trading platforms.
