CFTC staff has told registered exchanges that so-called “mention markets” should be treated as presumptively vulnerable to manipulation, putting extra scrutiny on a niche type of prediction contract rather than banning it outright.

These markets are typically yes-or-no contracts on whether a person will say a specific word or phrase during a speech, earnings call, livestream, podcast, or social post. Because the outcome can depend on a single person’s conduct, the agency’s market oversight staff said exchanges must make a stronger case if they want to list them.

What the advisory says

The September 22 advisory came from the Commodity Futures Trading Commission’s Division of Market Oversight and was addressed to designated contract markets, the exchanges registered with the CFTC. The staff pointed to Core Principle 3 of the Commodity Exchange Act, which bars exchanges from listing contracts that are readily susceptible to manipulation.

According to the CFTC’s explanation, most event contracts settle based on outcomes that no individual can control, such as election results or scheduled economic data. Mention markets differ because settlement can turn on the actions of one person. That creates the possibility that the speaker, or someone close to them, could influence the result or know the outcome in advance.

Why regulators see a higher risk

The staff said the label does not apply only to spoken words. It also covers contracts tied to attendance at an event or interactions such as handshakes. One example in the advisory involves a livestreamed podcast host and a catchphrase, where a trader could potentially affect the result by paying for a mention.

The CFTC said this is not just a theoretical concern. On August 28, the agency ordered former White House teleprompter operator Gabriel Perez to pay $172,539.02 after trading presidential mention contracts on Kalshi from December 2025 through February 2026 using advance access to speeches. The amount included forfeited profits, and Perez was barred from trading for three years.

Not a ban, but a higher bar for listing

The guidance does not create a formal prohibition and does not impose new obligations by itself. It also does not necessarily represent the position of the full commission. Instead, the advisory says exchanges can still seek to list mention markets if they rebut the presumption of manipulation in product filings submitted to the CFTC.

Duncan Hennes, the acting director of the Division of Market Oversight, signed the letter. In it, staff said they would expect a “heightened showing” to support any submission involving mention markets. The agency also said the four factors exchanges are expected to address are not exhaustive. Among the issues highlighted are whether the speaker faces legal or professional duties that would discourage tampering and whether the person could be exposed to outside pressure.

Limits of the CFTC’s reach

The practical effect of the advisory may depend on where these contracts are offered. Polymarket lists mention markets only on its international exchange, which is outside CFTC regulation. That means a stricter approach for registered US venues does not necessarily remove the product category from the broader market.

There is also a jurisdictional question in the background. In a separate matter, a judge who blocked Minnesota’s prediction market ban said Kalshi’s World Cup announcer mention markets likely are not swaps, the category that falls under the CFTC’s exclusive jurisdiction. For now, the confirmed next step is not an enforcement-wide ban but closer scrutiny of any attempt by CFTC-registered exchanges to bring these contracts to market.
