CFTC mention market advisory leaves Polymarket's offshore book untouched

The teleprompter operator's name was Gabriel Perez. He worked for the President of the United States, had access to what Trump would say before Trump said it, and traded event contracts on Kalshi that settled on exactly that information. The CFTC ordered him in August to pay $172,539. That enforcement action is the factual foundation underneath the Division of Market Oversight's advisory on mention market contracts — and the advisory is, in a meaningful sense, the CFTC drawing the circle it should have drawn before Perez ever opened an account.

The advisory sets out four factors that designated contract markets must weigh when designing mention contracts: whether the subject person has outside obligations that could shape their conduct; whether external pressures could influence their speech; whether settlement can be independently verified; and whether sufficient oversight exists to detect manipulation. These are not novel categories. They are Core Principle 3 applied to a contract type that the Commission had, for too long, evaluated with the same framework it uses for wheat futures. Wheat does not have a teleprompter operator.

What I find more consequential than the four factors is where the advisory stops. It is addressed to designated contract markets — entities regulated by the CFTC, subject to its Part 40 submission process, subject to Core Principle 3. Kalshi is in that category. Polymarket is not. Polymarket operates its mention markets through an international exchange outside CFTC jurisdiction, and the advisory does not reach it. That gap is not an oversight in the document; it is a structural feature of how the Commodity Exchange Act allocates authority. The Commission can raise the bar for the platforms it regulates. It cannot raise it for platforms that have declined to be regulated.

Kalshi's spokesperson said the company had already addressed the guidance based on prior discussions with the CFTC — which suggests the advisory formalized an understanding already reached between the agency and the platform rather than imposing new obligations by surprise. That is consistent with how the Commission typically moves: enforcement action first, then guidance that codifies what the enforcement action implied. The Perez order in August established the legal theory. The September advisory establishes the design standard that should prevent the next Perez.

The consensus reading of this advisory treats it as a regulatory tightening that disadvantages Kalshi relative to Polymarket, because Kalshi must comply and Polymarket need not. I think that framing understates what Kalshi gets from a formalized framework. A platform operating inside a regulatory structure it helped shape, with a documented compliance record, is in a different legal position than one operating outside that structure entirely — particularly before a court or a Congress that has to decide which model survives. The advisory is a burden, but it is also a credential.

The relevant standard under Core Principle 3 is that a designated contract market may list only contracts that are not readily susceptible to manipulation. The advisory does not define a safe harbor. It defines a process — consultation with Market Oversight, contract-specific analysis, four factors that must be addressed before submission. Whether any particular mention market contract can satisfy that process is a question each exchange answers with its own filing, reviewed on its own facts.
