CFTC staff tell exchanges to justify each contract that settles on one person's words
The Division of Market Oversight's September 22 advisory leaves mention markets legal, and it tells exchanges that a contract settling on one named person's conduct starts from a heightened manipulation risk they must answer contract by contract.

What happened
- Release Number 9302-26, dated September 22, 2026, from the CFTC's Division of Market Oversight, tells registered exchanges that contracts settling on whether a named person says a word, appears somewhere or interacts with someone carry heightened manipulation risk.
- Staff stopped short of banning the category, describing limited circumstances in which such contracts may be listed consistent with the Commodity Exchange Act plus non-exhaustive factors for venues to weigh.
- The advisory follows an August 28 order against Gabriel Perez, a former White House teleprompter operator who used advance access to President Donald Trump's prepared remarks to trade presidential mention contracts on Kalshi.
- The guidance is addressed to designated contract markets, the CFTC-registered venues that list event contracts for U.S. traders, and says such products should be listed only in narrow cases.
- A separate CFTC settlement in the same area was announced on July 31, 2026, weeks before the advisory went out.
Compiled by The ScientistSomething wrong?How this is made
Why it matters
- constraint The factors attach to the individual whose conduct settles the contract, so a venue cannot cover a group of contracts with one argument: each new named person is a fresh filing to write and defend.
- exposure The person whose words decide settlement is now inside the exchange's diligence: their confidentiality duties and the pressure on them become facts a venue has to establish before listing.
- decision Because a staff advisory is not a rule, an exchange that disagrees with staff's reading is choosing between redesigning contracts now and defending that reading in a later proceeding.
- contradiction Recipients of the letter see four named tests, per CNBC. Anyone reading the public release sees only unenumerated examples. The standard is more specific in private than in public.
An event contract on a published statistic depends on an outside record: the number is produced by a body with no position in the market, and anyone can look it up. A mention contract depends on a person. Settlement comes from that person's conduct [6].
The advisory's key sentence packs two different failure modes together. These contract types "present 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 Commission said [3]. "Independently generated" is about reaching the speaker; "externally verifiable" is about checking the record afterwards. By the account in The Crypto Times, a contract is easier to move when the deciding person can be influenced or what was said is hard to verify, compared with one tied to an election result, a CPI reading or a sports score [7].
The category-level warning sits on top of a per-contract remedy. Staff reminded exchanges of Core Principle 3, which requires them to list only contracts that are not readily susceptible to manipulation, and stressed the need for complete, contract-specific analysis under Part 40 [5]. Core Principle 3 is not new. The advisory tells venues how staff will read that existing obligation for one family of products, in a document that is a Division of Market Oversight staff advisory and not a Commission rule or vote [5].
CNBC, citing the staff letter sent to regulated entities, said exchanges weighing such products should assess at least four issues. They are outside legal, professional, contractual, fiduciary, confidentiality or organizational obligations on the person whose conduct decides settlement; external pressure that could shape that person's speech or appearance; whether the words or actions used for settlement are independently verifiable; and whether the exchange's surveillance and controls are strong enough to detect manipulation [8]. The CFTC's public press release does not list those four; it says the advisory provides "non-exhaustive examples of factors" [9].
Prediction markets have grown into a multi-billion-dollar business over the past year across politics, sports, culture and corporate events [12]. The published volume figures are exchange-wide totals. They cannot size the product line this advisory touches. DefiLlama data reported by The Crypto Times on July 5, 2026 put Kalshi's 30-day volume at about $10.19 billion [10]. DefiLlama research later put Kalshi's July monthly volume at $12.37 billion [11]. The two cover different windows, so the $2.18 billion between them is not a revision [2]. DefiLlama aggregates market data and is not an on-chain tracker for Kalshi's off-chain CFTC books [11].
One enforcement case supplies the only measured numbers in the category. The Perez order splits into $107,539.02 of disgorged profits and a $65,000 civil monetary penalty, with a three-year trading ban across CFTC-registered platforms [15]. The penalty is about 38 percent of the sum [1]. Set those profits against the $12.37 billion July tally and they come to roughly $8.70 for every million dollars traded, though Perez traded months earlier [3]. The CFTC described the $65,000 as a substantial discount for "exemplary cooperation" and credited KalshiEX with assisting the inquiry [15].
What to watch
- Whether the Commission itself votes a rule on mention contracts, which would replace a staff reading with binding text.
- The first mention-contract submission under Regulation 40.2 or 40.3 after September 22, and whether staff objects to it.
- Any enforcement order naming a second exchange, which would take the record past one venue and one trader.
