Feds probe 'mention markets' amid White House Kalshi controversy

Kalshi pulled sports mention markets as regulators examine whether the wagers are too easy to manipulate, after a White House betting scandal raised concerns.

  • Federal regulators have launched a review of "mention markets" on prediction platforms, where bettors wager millions on whether public figures say specific words, citing concerns that contracts are "readily susceptible to manipulation."
  • Last month, regulators revealed President Trump's longtime teleprompter operator Gabriel Perez allegedly profited from betting on presidential speeches using Kalshi, prompting the agency to examine the category after the platform's surveillance flagged suspicious trades.
  • During the World Cup final, a Fox sportscaster mistakenly identified Matt Damon as Brad Pitt, causing Kalshi's market to settle incorrectly despite the actor not attending; traders currently wager on terms like "MVP" and "ankle" across about $3.3 million in monthly volume.
  • In response, Kalshi removed sports mention markets "until further notice" while allowing contracts on political events and corporate earnings calls to remain active, significantly impacting a category representing more than 80% of platform trading volume.
  • Kalshi head of market operations Arjun Sawai argued manipulation concerns are "overstated," while the CFTC prepares to discuss prediction markets at its Innovation Advisory Committee meeting on August 20 amid broader regulatory battles with nine states over jurisdiction.
