CFTC Staff Advisory Says Prediction Market 'Mention' Contracts Invite Manipulation

Staff in the Commodity Futures Trading Commission's Division of Market Oversight issued an advisory stating that prediction-market contracts which settle on whether a named person utters particular words or engages in specific interactions should be presumed to be readily susceptible to manipulation. The advisory, signed by acting division director Duncan Hennes, expands the category commonly called "mention markets" beyond speech to include attendance, handshakes, photographs and social media engagement. The staff observed that settlement in these products often depends on the discrete conduct of an identifiable individual, which may not be independently generated or externally verifiable.

The advisory notes how simple it can be to induce the outcome of a mention contract: a podcast host could be prompted to use a catchphrase, or a participant could be paid or asked a question that produces the required action. Staff treat those closest to such outcomes — who may hold scripts, prepared remarks or guest lists — as likely to possess material nonpublic information. Because designated contract markets must list only contracts not readily susceptible to manipulation under Core Principle 3, the staff said exchanges should face a rebuttable presumption against these products unless they provide heightened evidence and surveillance safeguards.

To rebut the presumption, staff said exchanges should demonstrate that the referenced individual faces legal or professional duties that deter interference, that the conduct is publicly scrutinized or independently verifiable, and that robust surveillance and controls are in place. The advisory suggests concrete measures exchanges could use, including restricted lists of participants with ties to contracts, third-party screening, pop-up trading warnings, and position limits sized so manipulation would be more costly than profitable.

The advisory does not have the force of law; it reflects the views of Division of Market Oversight staff rather than a Commission rule. It follows the CFTC's recent settlement with Gabriel Perez, a former White House teleprompter operator who was fined $172,000 for trading on presidential mention contracts using speeches he had seen in advance. The guidance also arrives amid broader regulatory work on event contracts, including a June CFTC proposal on categories of impermissible subjects and an ongoing dispute over whether states or the federal government regulate certain event contracts such as sports betting, which has prompted legal actions by the Justice Department and the CFTC against several states.
