A staff advisory requires prediction-market exchanges to submit contract-specific analysis before listing contracts that settle on what a person says or does. It names the factors the agency will weigh.
The Commodity Futures Trading Commission's new guidance on "mention markets" does not tell exchanges they cannot list them. It tells them what they will have to show before they do.
The advisory, issued Tuesday by the agency's Division of Market Oversight, covers event contracts that turn on whether a particular person utters specific words, shows up at an event or meets a certain individual. These contracts carry "a heightened risk of manipulation because their settlement turns on the discrete conduct of a person that may be neither independently generated nor externally verifiable," the division said.
The advisory's concern is structural. Most event contracts settle on outcomes that many people influence, such as an election or an economic data release. A mention contract can settle on the choice of a single person, and that person, or someone close to them, may be able to trade on it.
Rather than prohibit the category, the CFTC is requiring designated contract markets to submit contract-specific analysis showing compliance with Core Principle 3, the requirement that a contract cannot be easily manipulated, before the product goes live. The advisory lays out the factors it will weigh.
The first is whether the individual whose words or actions settle the contract faces independent legal or professional obligations. A person bound by rules about what they can disclose or say may present a different risk than one who faces no such limits. The second is vulnerability to proxy manipulation, meaning whether someone else, such as an aide or associate, could influence or learn the outcome in advance. The third is public verifiability, whether the settling event can be confirmed from an independent public record. The fourth is the exchange's own surveillance capacity, whether it can detect suspicious trading around the contract.
Those factors could sort mention contracts into very different groups. A contract on phrases used in a scripted, publicly recorded address, spoken by someone subject to professional rules, may clear the test more easily than one on an unscripted remark by a private individual whose staff could trade on advance knowledge. The advisory puts the burden of drawing those distinctions on the exchanges.
The guidance arrives amid wider scrutiny of prediction markets. CFTC Chairman Michael Selig said Wednesday that "a large number of these contracts have issues," and that the agency would take a hard approach in evaluating them. Kalshi has also been defending trading patterns in its ether perpetual futures market.
For exchanges, the effect will show in their filings. Each new mention contract now needs a manipulation analysis, which raises the cost of listing and gives the CFTC a record to review. The first contracts listed under the new standard, and any the agency challenges, will show where the line falls in practice.
