Active regulatory inquiry — August 13, 2026
Federal regulators have opened an inquiry into prediction market “mention markets.” Kalshi has suspended all sports-category mention contracts. The CFTC has not publicly confirmed the inquiry or issued an enforcement action.
Mention markets let traders wager on whether a specific word or phrase will be spoken during a real-world event. Kalshi — Kalshi’s the largest CFTC-regulated prediction market in the U.S. — made mention markets a signature product category. Contracts ranged from whether a sportscaster would say “MVP” during a broadcast to whether an executive would utter a company name on an earnings call.
On August 13, 2026, NPR reported that the Commodity Futures Trading Commission had opened an inquiry into the category. Kalshi responded by removing all sports mention markets from its platform “until further notice.” Political, earnings-call, and live-news mention markets remained active as of the same report.
This page explains what mention markets are, why regulators are concerned, which contracts are suspended versus active, and what the legal standard at the center of the probe means for the future of the category.
A mention market contract answers one binary question: will a named word or phrase appear in a specified source — a broadcast transcript, a named outlet’s article, or a coverage list defined in the contract rules?
Resolution depends entirely on the defined source of truth. Whether you heard the word live doesn’t matter — only what the approved source records counts.
Two people with direct knowledge of the probe told NPR the CFTC had opened an inquiry. Neither Kalshi nor the CFTC confirmed or denied the report. No enforcement notice, formal order, or public statement has been issued. An inquiry is not a finding — it means regulators are reviewing the category, not that they have determined any violation occurred.
“These mention markets are not popular across the political aisle. They are potentially very easy to manipulate, so the CFTC is taking a hard look at whether some of them make sense.”

As of the August 13 NPR report, Kalshi made a targeted suspension of sports mention markets while leaving other categories in place. Status may change — confirm at kalshi.com/markets before trading.
| Category | Examples | Status |
|---|---|---|
| Sports broadcasts | "MVP," "ankle," "redshirt" on sports coverage | Suspended |
| Political appearances | Words spoken by the President, senators at public events | Still active |
| Earnings calls | Words spoken by executives on company earnings calls | Still active |
| Live news broadcasts | Words spoken by anchors or guests on TV news | Still active |
| Polymarket (global) | Various mention categories | Offshore only |

Kalshi operates as a CFTC-regulated Designated Contract Market (DCM). Under the Commodity Exchange Act, every DCM must meet Core Principle 3: markets must list only contracts that are not “readily susceptible to manipulation.” The full framework is codified at 17 CFR Part 38.
The core tension with mention markets is structural. Standard event contracts — like whether a bill passes in Congress or which team wins a championship — depend on a complex array of facts that no single person can determine unilaterally. A mention contract can work differently: a single broadcaster, executive, or politician can determine the outcome merely by saying — or deliberately avoiding — a particular word.
Outcome requires many actors (e.g., vote of 435 members)
No single participant can determine settlement
Aggregate outcomes harder to manipulate
Sports performance contracts (team wins, player stats)
Single speaker controls outcome by saying / not saying a word
Insider with advance knowledge of speech content has systematic edge
Resolution turns on one observable act by one person
Contracts denominated in words, not aggregate data
The CFTC probe did not emerge from a theoretical concern. Two prior cases — both involving Kalshi mention markets — demonstrated the real-world insider risk.
Kalshi surveillance flagged mention-market trades tied to words in presidential appearances and referred the activity to federal authorities. Reuters reported that more than $90,000 in potential profits were frozen.
A CEO read mention-market terms during his own company's earnings call. Contracts resolved Yes under the rules as written, raising the CFTC Core Principle 3 listing-standard question of whether a named speaker can determine their own contract.
Mention markets are offered on Polymarket's offshore international site but are not available on Polymarket's smaller CFTC-regulated U.S. platform. Polymarket’s global offshore platform offers mention markets but those products are not listed on the CFTC-regulated U.S. version of the site. The CFTC inquiry focuses on CFTC-regulated Designated Contract Markets — which means Polymarket’s offshore products are outside the regulator’s direct reach, while Kalshi’s mention contracts are squarely within it.
CFTC takes no action
Regulators conclude the existing surveillance and contract design adequately address manipulation risk. Sports mention markets return with no structural changes.
CFTC requires structural changes
Kalshi modifies contract eligibility (for example, only mentions by speakers who could not have advance notice), updates resolution sources, or adds pre-launch disclosure requirements. A modified version of mention markets continues.
CFTC determines category fails the standard
Regulators find that word-based contracts are inherently susceptible to manipulation because a single speaker always controls the outcome. Some or all mention categories are delisted. Kalshi could appeal or restructure.
CFTC issues formal guidance
The inquiry leads to a broader rule or advisory covering all prediction market mention contracts — shaping the category industry-wide, not just for Kalshi.
No timeline has been announced. The CFTC has not stated which outcome it is pursuing. Developments will follow any formal CFTC statement, Kalshi filing, or court action.
A mention market is a prediction market contract that resolves based on whether a specific word or phrase is spoken by a named person (or anyone) during a defined event — a sports broadcast, an earnings call, a political speech, or a live news segment. Traders buy Yes if they think the word will be uttered, No if they think it will not. Resolution depends on a defined source of truth, not on what anyone heard live.
Federal regulators are examining whether certain mention markets are 'readily susceptible to manipulation' — a legal standard under the Commodity Exchange Act that every Designated Contract Market must meet. The concern is that a single person (a sportscaster, an executive, a politician) can, deliberately or not, determine a contract's outcome simply by saying — or not saying — one word. That structure may not satisfy the anti-manipulation core principle that applies to CFTC-regulated exchanges.
According to the NPR report that broke the story on August 13, 2026, Kalshi removed all mention markets related to sporting events 'until further notice.' That includes contracts on words spoken by sportscasters, athletes, or commentators during games. Political mention markets, earnings-call mention markets, and live-news mention markets were still active as of the same report.
No. As of August 14, 2026, the CFTC has not publicly confirmed the inquiry, issued a formal notice, or published an enforcement action. Both the CFTC and Kalshi declined to comment to NPR. The information comes from two sources with direct knowledge of the probe who spoke on condition of anonymity. This is an inquiry — not a formal enforcement action.
The Commodity Exchange Act requires that Designated Contract Markets list only contracts that are not 'readily susceptible to manipulation' (Core Principle 3, 17 CFR Part 38). The CFTC's concern is that mention markets — where a single speaker can determine settlement by saying or not saying a single word — may fail that standard for certain categories. The regulator has not made a formal finding.
A case involving Gabriel Perez, described as President Trump's longtime teleprompter operator, exposed the insider-risk problem. Kalshi's internal surveillance systems flagged suspiciously well-timed mention-market trades tied to words in presidential appearances and referred the activity to federal authorities. Reuters reported that more than $90,000 in potential profits were frozen. The case drew significant attention to how mention markets can be exploited by insiders.
Polymarket's offshore international site offers mention markets, but they are not available on Polymarket's smaller CFTC-regulated U.S. platform. The CFTC probe focuses on CFTC-regulated markets — so Polymarket's offshore products are outside the inquiry's direct reach, while Kalshi's markets are squarely within it.
The CFTC could conclude its review without action, seek changes to how sports mention contracts are structured, or determine that some word-based contracts cannot satisfy the anti-manipulation standard regardless of subject matter. Kalshi could also modify contract structures, eligibility requirements, or surveillance controls rather than abandon the category entirely. No timeline has been announced.
