Kalshi prediction site suspends three political candidates for betting on their own races | CNN Politics

The prediction market Kalshi suspended three political candidates from its platform on Wednesday for “political insider trading” after an internal probe found that they bet on their own campaigns. These suspensions and fines, reported first by CNN, are the most aggressive enforcement actions taken to date by a prediction site against political candidates, with primaries for the 2026 midterms already underway. The announcement comes as lawmakers from both parties have steadily raised concerns about how the rapidly expanding prediction market industry could potentially undermine the integrity of US elections. On prediction sites, users can bet on nearly everything from elections to sports, entertainment, or even the daily high temperature. (CNN has a partnership with Kalshi and uses its data to cover major events. However, editorial employees are not allowed to participate in prediction markets.) Robert DeNault, Kalshi’s head of enforcement, said in a statement announcing the suspensions that these cases are “political insider trading” and violated Kalshi’s rules as approved by the Commodity Futures Trading Commission, the federal agency that regulates prediction platform
