CFTC Advisory Flags Manipulation Risks in Mention, Attendance, and Interaction Event Contracts

The Commodity Futures Trading Commission’s Division of Market Oversight issued an advisory stating that mention market event contracts may be readily susceptible to manipulation. The guidance covers mention, attendance, and interaction contracts, which often depend on the discrete conduct of an individual. It emphasizes that risks can be overcome with appropriate safeguards.

According to reporting by InGame, the advisory reminds designated contract markets of core principles under which contracts may not be readily susceptible to manipulation. When self-certifying new contracts, DCMs must attest compliance.

Manipulation Risks and Industry Context

“DCMs should consider whether certain categories of event contracts, such as Mention Markets, have a heightened potential for manipulation,” the letter said. “Because the outcome of these contracts is often within the control of a small number of actors, the settlement condition is comparatively easier to cause, prevent, or influence for personal gain.”

The advisory details that where costs of manipulation or likelihood of detection are low and safeguards absent, the person determining settlement may influence outcomes or exploit advance knowledge. Contracts in informal or private settings or by non-public persons carry increased risk due to lack of public scrutiny and independent verification.

Mention markets have recorded $867.2 million in volume on Kalshi, about 2% of its non-sports volume, generating $5.2 million in fees. Controversies include Coinbase CEO Brian Andrews ending an earnings call by reading potential bet words, a former Trump teleprompter operator ordered to pay $172,000 for using inside information on speeches, and Kalshi stopping sports-related mention markets. CME CEO Terry Duffy has criticized such contracts as susceptible to manipulation.

Factors DCMs Must Evaluate

The advisory identifies four key factors for assessing whether a mention market is readily susceptible to manipulation: independent obligations constraining the controlling individual with disproportionate professional, legal, or reputational consequences; susceptibility to external pressure from others; independent verification and substantial public scrutiny, noting private or non-material actions are less verifiable; and robustness of prophylactic trading rules, surveillance, and controls.

It states nothing in the advisory should be read to discourage these markets and encourages early engagement with staff during contract design. The letter creates no new obligations and does not supersede existing rules. DCMs must include thorough evaluation of these factors in any self-certification.

Where the Risk Lies
The advisory underscores the need for DCMs to implement specific controls around individual-driven contracts to meet core principles, or face heightened regulatory scrutiny on listings.
