CFTC flags swaps-style rules, tightening oversight of prediction markets

As regulatory pressure escalates, US derivatives watchdogs are sharpening their focus on prediction markets and their exposure to insider trading risks.

CFTC enforcement signals a tougher stance

The Commodity Futures Trading Commission‘s top enforcement official, David Miller, has delivered one of the clearest warnings yet to traders in prediction platforms. Speaking at New York University, he stressed that insider trading rules do apply to these venues and confirmed the agency is closely monitoring suspicious activity.

Miller directly addressed growing speculation over the legality of trading on non-public information. “We are aware of the speculation about insider trading… We are watching,” he said, rejecting online narratives that suggest these rules can be ignored. Moreover, he called out a “myth in mainstream media and social media” that insider trading does not apply in these markets, stating bluntly: “That is wrong.”

These remarks mark an escalation in tone from the CFTC and signal that regulators intend to treat these platforms under existing market abuse and surveillance frameworks. However, Miller indicated that the Commission would pursue a targeted, rather than blanket, enforcement strategy.

Selective enforcement and focus on confidential information

According to Miller, the agency will prioritize cases involving the misuse of confidential or privileged information. That said, not every technical breach is likely to trigger a full enforcement response, as minor violations may attract less attention. This approach aims to distinguish between systemic misconduct and lower-level infractions.

The policy stance comes as online platforms that allow users to trade on real-world events have rapidly expanded. Monthly trading volume in these markets has now crossed $20B, pulling in both retail users and institutional participants. Moreover, regulators fear that some traders could be exploiting inside knowledge linked to policy decisions, national security matters, or sensitive geopolitical developments.

These concerns are amplified by highly specific contracts that can track outcomes ranging from elections to diplomatic actions. As liquidity and visibility have grown, so too has the risk that event-focused contracts could be used to monetize restricted government information.

Event contract classification as swaps, not gambling

Regulators are also working to clarify how these products are legally classified. Miller argued that event-based contracts should be understood as financial derivatives, not as simple wagers. “Our position is that event contracts are not gaming. The event contracts at issue are swaps. Insider trading law applies,” he said, underscoring the Commission’s view.

That interpretation pulls these instruments squarely under the umbrella of financial market law, including the broader commodity futures trading commission framework, rather than gambling statutes. In practice, it also reinforces that the full suite of market integrity and disclosure obligations can be brought to bear on these platforms.

This view may have long-term implications for how exchanges structure products and vet counterparties. However, for now, most of the regulatory attention remains on insider abuses and potential prediction market manipulation concerns tied to sensitive information flows.

Insider trading prediction markets and manipulation risks

Enforcement efforts are not expected to stop with insider trading alone. The Commission is also monitoring possible market manipulation schemes and assessing how well platforms comply with anti money laundering compliance standards. This includes tracking unusual order patterns and connections to external events.

Recently, lawmakers and regulators have highlighted a string of trades that appeared unusually well-timed. These include bets placed shortly before major announcements linked to Donald Trump, which have intensified public concern over unfair informational advantages.

In another widely discussed case, a trader reportedly earned more than $400,000 by correctly predicting the capture of Nicolás Maduro before the information became public. Moreover, trading activity around tensions involving Iran and speculation tied to other high-profile political figures has raised fresh questions about national security exposure and the integrity of these markets.

Platform rule changes and regulatory pressure

Under mounting scrutiny, major platforms such as Kalshi and Polymarket have both rolled out updated rulebooks aimed at curbing insider-driven trading. These kalshi polymarket rule changes are designed to make it harder for users with privileged access to monetize non-public information, while also demonstrating responsiveness to US authorities.

However, regulators have signaled that voluntary platform measures will not substitute for formal oversight. For example, Miller’s comments on insider trading prediction markets suggest that the agency expects robust internal controls and prompt cooperation when suspicious conduct is detected.

That said, exchanges are attempting to strike a balance between innovation and compliance. Some operators argue that transparent, well-regulated prediction platforms can improve price discovery around political and economic risk, provided governance standards are strong enough.

Legislative moves and future outlook

On Capitol Hill, policy-makers are moving in parallel with regulators. Multiple legislative initiatives are in progress, including the Public Integrity in Financial Prediction Markets Act of 2026 and the PREDICT Act. These proposals target the use of non-public information, with particular emphasis on limitations for government officials and individuals with access to classified data.

Moreover, some bills aim to bolster oversight mechanisms and clarify event contract classification, reducing ambiguity around what falls under financial regulation versus other legal categories. Supporters argue that a clearer statutory framework will help safeguard market integrity without eliminating the broader benefits of information aggregation.

As these debates unfold, prediction markets face a more formalized regulatory perimeter. Platforms will likely need to strengthen compliance systems and internal surveillance tools to stay aligned with the evolving expectations of US authorities.

Balancing innovation with integrity

Looking ahead, the sector’s trajectory will depend on whether operators can demonstrate that they can manage insider threats and manipulation risks effectively. That said, regulators appear determined to ensure that traditional safeguards around market abuse, disclosure, and fairness apply, even as new technologies reshape how information is priced.

For traders, the message from Miller and the CFTC is unambiguous: using privileged information to profit from event-driven contracts will be treated as a violation of law. As volumes grow and rules harden, the space will increasingly resemble traditional derivatives markets rather than an unregulated gray zone.

In summary, US authorities are moving to integrate these platforms into established legal and supervisory frameworks, tightening expectations on transparency, conduct, and the responsible use of non-public information.
