The Commodity Futures Trading Commission is reviewing 'mention markets' — prediction-market bets on specific words spoken by public figures, from President Trump to sportscasters — after revelations that Trump's longtime teleprompter operator used Kalshi to profit from correctly betting on the president's word choices. Kalshi's internal surveillance flagged the bets and reported them to authorities, and the company has now pulled all sports-related mention markets 'until further notice,' though it still allows word-betting on political events, earnings calls, and live newscasts.
Sports betting makes up over 80% of Kalshi's weekly trading volume, so removing sports mention markets is a significant cut. Regulators and Kalshi's own lawyers reportedly worry these markets are inherently easy to manipulate, violating rules requiring that self-certified markets not be 'readily susceptible to manipulation.' Polymarket still offers mention markets on its unregulated overseas site but not on its smaller U.S. platform.
The absurdity peaked during the World Cup final broadcast on Fox, when a sportscaster mistook Matt Damon for Brad Pitt on air; several news outlets repeated the error, and Kalshi's market settled as if Pitt had attended, per its contract rules, even though he was never there. Traders who correctly bet Pitt wasn't present collectively lost $287,866 because of the broadcaster's mistake.
