CFTC Staff Advisory Says Prediction Market ‘Mention’ Contracts Invite Manipulation

Prediction market contracts that settle on whether a named individual says particular words, turns up somewhere or interacts with someone else should be treated as presumptively open to manipulation, staff at the Commodity Futures Trading Commission’s Division of Market Oversight said on Tuesday.

The category, which the industry calls mention markets, reaches well beyond speech, taking in contracts on attendance, handshakes, photographs and social media engagement.

Most event contracts settle on outcomes nobody controls, such as economic data, election results or sports. In mention markets, settlement turns on the discrete conduct of one named person, which staff wrote may be “neither independently generated nor externally verifiable.”

The advisory cites the example of a contract on whether a podcast host uses a catchphrase; the host can simply say it, and a trader can induce the outcome by submitting a question or paying for an on-air mention. Those nearest the outcome often hold scripts, prepared remarks or guest lists, which staff treat as material nonpublic information.

Designated contract markets, the registered exchanges that list these products, must under Core Principle 3 list only contracts not readily susceptible to manipulation. The presumption can be rebutted. Staff will weigh whether the individual faces legal or professional obligations that deter interference, whether they can be pressured by others, whether the conduct is independently verifiable and publicly scrutinized, and how robust the exchange’s own surveillance is.

Staff suggest restricted lists of participants with contract affiliations, third-party screening, pop-up warnings before trading, and position limits sized so that manipulation would cost more than it could earn.

The advisory carries no legal force, representing the views of division staff rather than the Commission, and is signed by acting director Duncan Hennes. It follows the CFTC’s settlement last month with Gabriel Perez, a former White House teleprompter operator who was fined $172,000 over trades on presidential mention contracts using speeches he had seen in advance.

It also lands inside a wider effort to fix what event contracts may cover. In June the Commission proposed a framework for judging whether a contract involves terrorism, assassination, war, gaming or unlawful conduct, and would bar sports contracts settling on discrete player actions such as fouls or individual plays, reasoning today’s advisory cites directly.

Who regulates any of this is still contested. States have argued in a run of federal lawsuits that sports event contracts are unlicensed betting, and in April the Justice Department and the CFTC sued Illinois, Arizona and Connecticut to assert the agency’s exclusive authority.
