On September 22, 2026, the CFTC's Division of Market Oversight (DMO) issued CFTC Letter No. 26-27, a Staff Advisory addressing a novel category of event contracts: "mention market" contracts that settle based on an individual's speech, attendance, or interactions.

What are "mention contracts" and how do they relate to event contracts?

Traditional event contracts settle on independently verifiable outcomes outside any single person's control, such as election results, economic data releases, or sporting event outcomes. Mention markets are different in that they settle on discrete, individual conduct. For example:

• Whether a person utters specific words or phrases (e.g., a catchphrase during a live-streamed podcast or buzzword on an earnings call)
• Whether an individual attends or appears at a particular event
• Whether specific interactions occur (e.g., a handshake, photograph, or social media engagement)

Risks associated with mention contract markets

DMO staff view mention markets as presumptively readily susceptible to manipulation for several interrelated reasons:

• Single-actor control: Settlement often hinges on conduct controllable by one person or a small group.
• Material nonpublic information: Those closest to the outcome frequently possess advance knowledge, scripts, guest lists, or unpublished content, constituting material nonpublic information and creating opportunities for trading advantages.
• External pressure vulnerability: Outcomes may be influenced through social engineering, inducements, or public pressure campaigns.
• Detection challenges: Contracts settling on private, informal, or non-substantive actions could escape public scrutiny, concealing manipulation.

Existing law & guidance on-point

The advisory notes that existing regulation, DCM Core Principle 3, already requires that contracts not be readily susceptible to manipulation. DMO staff expect any Part 40 filing for mention market contracts to include:

• A thorough evaluation of manipulation risks
• Detailed prophylactic measures, such as: 
  • Enhanced monitoring and surveillance
  • Position limits and accountability rules
  • Restricted trading lists for insiders and controllers
  • "Pop-up" confirmations and third-party screening

DMO staff view independent verifiability and substantial public scrutiny as essential attributes for listing mention market contracts consistent with Core Principle 3.

Practical takeaways

Those considering developing or listing mention market contracts should take note of this CFTC Advisory and consider whether controlling individuals are subject to independent legal, professional, or fiduciary obligations that deter manipulation.

Remember, the CFTC advisory is nonbinding and purely informational regulatory guidance helpful for understanding regulator thinking, views, interpretations, positions, or expectations.
