CFTC Puts Prediction-Market Exchanges on Notice Over 'Mention' Contracts

The Commodity Futures Trading Commission's market oversight division issued an advisory Tuesday warning that prediction contracts based on an individual's words or actions carry a heightened risk of manipulation. The guidance, sent to regulated exchanges, says such 'mention markets' can only be listed in 'limited circumstances' consistent with the Commodity Exchange Act.

Mention markets are event contracts tied to whether a person says a specific word, appears at an event, or interacts with someone else. The CFTC said these contracts settle on 'the discrete conduct of a person that may be neither independently generated nor externally verifiable,' leaving them prone to manipulation.

The advisory came roughly a month after the CFTC penalized a former White House teleprompter operator for trading prediction contracts linked to President Donald Trump's speeches. In that case, the individual was ordered to forfeit $107,539 in profits and pay a $65,000 civil penalty, Cointelegraph reported.

According to CNBC, the CFTC letter tells exchanges to weigh four factors when deciding whether to list mention contracts: whether oversight measures can detect manipulation, whether the settlement-triggering words or actions are independently verifiable, whether external pressure could sway the subject's behavior, and what outside obligations the person might have.

CFTC Chair Mike Selig welcomed the guidance on X, writing that 'regulatory clarity drives sound markets.' He added that he was pleased to see staff address the risks and remind designated contract markets of their duty to list only contracts that are not readily susceptible to manipulation.

The advisory follows earlier scrutiny. CNBC and NPR reported in August that the regulator had begun reviewing mention markets, and Kalshi, a cryptocurrency-based prediction exchange, suspended such contracts tied to sporting events 'until further notice' during the inquiry.

Separately, unusual trading volume on Kalshi has drawn attention. The Wall Street Journal reported Tuesday that a market tied to the price of Ether saw nearly one million trades worth over $5 billion in August, with more than a third executed in nearly identical amounts of roughly $5,500. Federal regulators and traders have taken notice, according to the Journal, though Kalshi has denied that the activity amounted to wash trading.

Tuesday's advisory formalizes the CFTC's position on a contract type that has grown popular in recent years, as exchanges have offered bets on everything from political speeches to public appearances. The agency's message is clear: listing such contracts without robust safeguards may run afoul of the law.
