CFTC Tightens Scrutiny of Mention Markets in the United States
United States.- 25 September 2026 | www.zonadeazar.com The Commodity Futures Trading Commission, CFTC, has issued new guidance for prediction markets offering contracts linked to what an individual may say, mention or do during an event.
These products, known as mention markets, can settle according to whether an individual says particular words, appears at an event, attends an activity or interacts with another person.
The US regulator believes these contracts present heightened manipulation risks because settlement may depend directly on the behaviour of an individual capable of influencing the underlying event.
New CFTC Guidance
The guidance was issued on 22 September 2026 by the CFTC’s Division of Market Oversight, DMO.
It is intended to explain how these products should be assessed under the regulatory framework governing event contracts and prediction markets.
The advisory does not create a blanket prohibition on mention markets.
Instead, it describes the limited circumstances in which these products may be listed consistently with the Commodity Exchange Act and Commission regulations.
What Are Mention Markets?
Mention markets are event contracts whose outcome depends on a specific action by an individual.
They may ask whether somebody will:
- Say a particular word.
- Mention a specific topic.
- Attend an event.
- Appear at a particular activity.
- Interact with another individual.
- Carry out another objectively identifiable action.
These products form part of the recent expansion of prediction markets in the United States.
Binary Contracts
Many event contracts use a binary structure.
Participants take positions on two possible outcomes, generally expressed as “yes” or “no”.
For mention markets, settlement can depend on an extremely specific action occurring within a defined period.
This differentiates them from products based on broader events that are independent of one individual’s behaviour.
Heightened Manipulation Risk
The CFTC’s primary concern is manipulation.
The regulator believes these products may be particularly vulnerable because their settlement can depend on discrete conduct that is not independently generated.
An individual may be able directly or indirectly to alter the event determining the contract’s outcome.
Control Over the Outcome
The problem becomes particularly significant when the subject of the contract knows that the market exists.
If somebody knows traders are wagering on whether they will say a particular word, that person could deliberately modify their behaviour.
This differs substantially from events whose outcomes cannot easily be controlled by a single individual.
Non-Public Information
Another concern involves access to advance information.
People close to the individual could know beforehand:
- The contents of a speech.
- Topics that will be discussed.
- Participants attending a meeting.
- An event agenda.
- Planned interactions.
- Prepared statements.
That information could provide a significant trading advantage over the wider market.
External Verification
The CFTC also emphasised the importance of externally verifiable outcomes.
Markets need clear and objective criteria for determining whether the specified event occurred.
Settlement should not depend on ambiguous interpretations or information that cannot be independently verified.
Independently Generated Conduct
The regulator is particularly interested in whether the conduct determining settlement would occur independently of the existence of the contract.
The greater the possibility that the market itself could influence the relevant behaviour, the greater the regulatory risk.
This principle sits at the centre of the new guidance.
Designated Contract Markets
The advisory is particularly relevant to Designated Contract Markets, or DCMs.
These platforms are authorised by the CFTC to list and trade regulated contracts.
DCMs have specific regulatory responsibilities before introducing new products into the US market.
Core Principle 3
The CFTC reminded DCMs of their obligations under Core Principle 3.
This requires designated markets to list only contracts that are not readily susceptible to manipulation.
The requirement applies both to initial product design and to the conditions under which the product will trade.
Contract-Specific Analysis
The regulator stressed that operators cannot rely solely on generic analyses.
Each contract must be assessed according to its individual characteristics.
The CFTC expects detailed explanations of the specific risks created by a product and the safeguards designed to mitigate them.
Part 40
Markets submitting new contracts must comply with procedures established under Part 40 of CFTC regulations.
These rules govern how products are filed with the Commission.
Depending on the circumstances, contracts may be submitted through self-certification or through a request for prior approval.
Regulations 40.2 and 40.3
The advisory specifically refers to Regulations 40.2 and 40.3.
Regulation 40.2 addresses the self-certification process for new products.
Regulation 40.3 provides a mechanism for designated markets to seek Commission approval.
The CFTC expects platforms to provide sufficient information for regulators to assess compliance.
Individual Product Analysis
The regulator is signalling that submitting large groups of products with nearly identical explanations may not be sufficient.
DCMs must analyse the individual characteristics of each contract.
This includes identifying who may influence the event and how manipulation could occur.
Risk Factors
Relevant factors may include:
- An individual’s ability to influence the outcome directly.
- Advance knowledge of speeches or events.
- Availability of non-public information.
- Potential coordination between participants.
- Ease with which behaviour can be changed.
- Clarity of settlement rules.
- Availability of independent verification sources.
These factors can affect whether a product satisfies regulatory requirements.
Individuals Connected to the Event
The risk does not apply solely to the person whose behaviour determines settlement.
It can also extend to those around them.
Advisers, employees, organisers, event participants and other individuals may possess relevant information before it becomes public.
Direct Manipulation
Mention markets have one particularly important characteristic: in some circumstances, changing the outcome can be extremely simple.
Saying or avoiding a particular word may require far less effort than altering the outcome of a complex external event.
This helps explain the additional scrutiny applied by the CFTC.
Indirect Influence
Manipulation does not necessarily have to come from the person named in the contract.
A third party could attempt to induce the relevant behaviour.
For example, somebody could ask a deliberately constructed question intended to make an individual mention a particular word or subject.
This increases surveillance challenges.
Appearance Markets
The guidance is not limited to spoken words.
It also covers contracts based on whether an individual appears at or attends a particular event.
These products may similarly depend on decisions that can easily be altered or information known in advance by a limited group.
Interaction Markets
Another category involves contracts based on whether two individuals interact.
This may include meetings, public encounters or other types of contact.
The CFTC believes such events require careful analysis before they become the underlying condition of a tradable contract.
Prediction Markets
Prediction markets allow participants to trade contracts whose value depends on the outcome of future events.
These products may be used for speculation as well as to express expectations about specific outcomes.
In the United States, event contracts offered on regulated markets fall under CFTC oversight.
Growth of Event Contracts
The range of event contracts has expanded substantially in recent years.
Platforms have progressively added new categories of products.
Contracts can reference sporting, economic, cultural and other events with verifiable outcomes.
Product Innovation
Competition has encouraged platforms to develop increasingly specific products.
Mention markets represent one example of this innovation.
However, the narrower and more controllable a settlement condition becomes, the greater the potential for individual market participants to influence the outcome.
No Blanket Ban
The CFTC has not stated that all mention markets are automatically unlawful.
The regulator recognises that limited circumstances may exist in which these contracts can be listed consistently with applicable rules.
The burden is on markets to demonstrate that appropriate safeguards against manipulation have been incorporated into the product.
Case-by-Case Assessment
The regulatory approach is fundamentally contract-specific.
Risk can vary depending on:
- The individual involved.
- The event.
- The type of conduct.
- Information availability.
- Settlement sources.
- Market structure.
Not every mention market will therefore necessarily receive identical treatment.
Platform Responsibility
DCMs are responsible for assessing their products before submitting them.
The existence of a self-certification process does not remove that obligation.
The CFTC expects platforms to carry out substantive rather than merely administrative analysis.
Self-Certification
The US framework permits certain products to be filed through self-certification.
The market certifies that the contract complies with applicable rules.
However, the CFTC retains supervisory authority and can examine whether the analysis supporting a filing is sufficient.
Increased Regulatory Scrutiny
The new advisory forms part of a broader period of heightened oversight of prediction markets.
Industry expansion has led the regulator to examine contract design, filing procedures and trading structures more closely.
The CFTC has also issued other guidance during 2026 addressing self-certification and incentive programmes.
Incentive Programmes
In August 2026, the Division of Market Oversight published separate guidance covering market-maker, liquidity and other incentive programmes used by prediction markets.
That advisory identified procedural and substantive deficiencies in some regulatory filings.
The mention market guidance continues this broader push for stronger documentation and contract-specific analysis.
Market Integrity
Preserving market integrity is a central objective of CFTC supervision.
Products need to be designed so that the possibility of manipulation is appropriately controlled.
Markets must also maintain surveillance systems capable of detecting suspicious activity.
Surveillance
For highly specific contracts, surveillance may be particularly important.
Platforms may need to monitor:
- Unusual price movements.
- Large positions.
- Trading immediately before an event.
- Activity by connected individuals.
- Sudden changes in trading volume.
These factors may indicate potential manipulation.
Conflicts of Interest
Mention markets can also generate conflicts of interest.
Somebody with direct knowledge of the underlying event may simultaneously possess a financial incentive to influence it.
The existence of this incentive distinguishes these contracts from products based on fully external events.
Product Design
The advisory increases the importance of precise contract design.
Platforms need to define:
- What conduct qualifies as a valid outcome.
- When the relevant period begins and ends.
- Which sources determine settlement.
- How ambiguous situations will be resolved.
- What measures mitigate manipulation.
Poorly drafted terms can increase both commercial and regulatory risk.
Regulatory Context
The CFTC is currently conducting a broader review of prediction markets and event contracts.
During 2026, the Commission has sought public input on a range of regulatory questions relating to these products.
Issues include the types of contracts that may be offered, applicable core principles and categories that may raise broader public-interest questions.
Innovation and Oversight
The CFTC itself identifies prediction markets and event contracts as one of its innovation focus areas.
The regulatory challenge is to allow new products to develop without weakening market-integrity protections.
Mention markets provide a particularly clear example of that tension.
Industry Context
Prediction markets are undergoing rapid expansion in the United States.
Competition is encouraging platforms to offer contracts on increasingly narrow and specific outcomes.
This growth is requiring both operators and regulators to define more clearly the boundaries between innovation, speculation and manipulation risk.
Next Steps or Impact
The CFTC guidance may prompt DCMs to review existing mention markets and raise the level of analysis applied before new products are filed.
Platforms will need to demonstrate that contracts are not readily susceptible to manipulation and that suitable verification and surveillance mechanisms are in place.
The advisory may also influence the speed at which new event contracts reach the market.
Rather than prohibiting the category, the CFTC is raising the regulatory standard for demonstrating that each product can operate within an orderly, verifiable and manipulation-resistant market.
