The U.S. Commodity Futures Trading Commission (CFTC) on Tuesday issued an advisory warning to its regulated platforms regarding 'mention markets'—prediction market contracts based on whether a person says certain words or performs specific actions—stating that listing such instruments is only permissible in limited circumstances. The warning followed a case in which a former White House teleprompter operator was required to return $107,539 in profits and pay a $65,000 civil penalty for trading contracts tied to speeches by U.S. President Donald Trump.

Increased Manipulation Risk Due to 'Discrete Behavior'

The regulator noted that settlement of these contracts depends on the discrete behavior of a specific individual, which may not arise independently and cannot be externally verified. On this basis, the CFTC sees an elevated risk of manipulation and emphasized growing attention to the integrity of prediction markets.

Four Criteria for Listing 'Mention' Contracts

The letter stated that exchanges should assess: the adequacy of surveillance to detect manipulation; independent verifiability of the words or actions used for settlement; external pressures that could influence the subject's behavior; and any other obligations of the subject that may affect such behavior.

CFTC Chair Supports Clarification

CFTC Chair Mike Selig welcomed the publication of the guidance, noting on X that "regulatory clarity drives sound markets," and reminded exchanges of their duty to list only contracts that are not susceptible to manipulation.
