CFTC Warns of Manipulation Risks in Prediction Markets
- CFTC alerts regulated entities about increased manipulation risks in “mentions” contracts.
- Agency does not impose new obligations but provides guidance under the Commodity Exchange Act.
- Concerns arose after insider trading incidents related to contracts influenced by public speeches.
The Commodity Futures Trading Commission (CFTC) has issued a warning to its regulated entities regarding the heightened risk of manipulation associated with “mentions” contracts in prediction markets. This notification was conveyed in a letter sent to designated contract market entities on September 4, 2026.
In the press release accompanying the letter, the CFTC stated that these contracts are particularly vulnerable to exploitation “because their settlement turns on the discrete conduct of a person that may be neither independently generated nor externally verifiable.”
It is important to note that the CFTC is not establishing new requirements for regulated exchanges. Rather, the agency is advising on appropriate circumstances for listing mention markets in compliance with the Commodity Exchange Act, which governs the commodities regulated by the CFTC. Mention markets consist of contracts that predict specific words being used during speeches, corporate earnings calls, or television broadcasts.
The CFTC’s concerns about mention markets have intensified following reports of an internal review of this contract type. In response to the scrutiny, the prediction market platform Kalshi removed its sports-related mention markets.
The mention markets gained further notoriety in July when it was revealed that Gabriel Perez, a longtime teleprompter operator for President Donald Trump, profited from trades based on contracts linked to the president’s statements. Perez settled with the CFTC in August, paying a $172,539 fine for insider trading within a prediction market.
The letter outlined four key factors that exchanges should consider when listing mention markets: the external obligations of the subject, any external pressures influencing the subject’s words or actions, the verifiability of the settlement criteria, and the effectiveness of oversight measures to identify potential manipulation.
Additionally, the CFTC encourages exchanges to consult with its division of market oversight during the initial phases of designing mention market contracts to better mitigate manipulation risks.
Disclosure: CNBC and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.
