The U.S. Commodity Futures Trading Commission cautions that “mention markets” — wagers on an individual’s statements or actions — present distinct regulatory concerns for firms such as Kalshi and Polymarket. An advisory released Tuesday could limit the availability of event contracts that would readily satisfy the agency’s oversight requirements.
Unlike traditional markets whose outcomes are independently generated and externally verifiable, the result of a mention market depends on the specific conduct of a named individual, which may not be independently generated nor externally verifiable, according to the CFTC staff advisory.
Consequently, participants close to the individual may influence the outcome using insider knowledge. The CFTC’s Division of Market Oversight considers these markets potentially highly manipulable, as stated in the advisory. Accordingly, the CFTC reminds operators of prediction platforms that they may only trade derivative contracts that are not readily susceptible to manipulation.
