Polymarket has introduced stricter rules to curb insider trading and market manipulation across both its DeFi platform and its Commodity Futures Trading Commission-regulated U.S. exchange. The update includes enhanced surveillance systems, oversight from the National Futures Association, and formal channels for whistleblowers to report suspicious activity.
Summary
Polymarket has rolled out upgraded integrity policies covering both its decentralized platform and regulated U.S. exchange.
The new framework strengthens restrictions on insider trading, manipulation, and abusive trading practices, supported by advanced monitoring and reporting mechanisms.
The move comes as prediction markets expand rapidly under U.S. regulatory oversight and attract growing institutional interest.
The updated rules clearly define three types of prohibited insider activity: trading on stolen confidential information, acting on unlawful tips, and trading by individuals who have the power to influence the outcome of an event. Participants are barred from using privileged information obtained through breaches of trust or from taking positions when they hold authority over the underlying event.
In addition, Polymarket has reinforced a broad ban on manipulative practices such as spoofing, wash trading, fake transactions, front-running, self-dealing, and any actions that could disrupt fair market conditions.
Enhanced monitoring and enforcement
On its U.S. exchange, Polymarket will rely on a multi-layered surveillance system that includes real-time monitoring, partnerships with specialized compliance technology firms, and a regulatory services agreement with the National Futures Association. Violations could result in penalties such as suspension, account termination, fines, or referrals to regulators and law enforcement agencies.
For its DeFi platform, users can report suspicious behavior through community channels like Discord or via dedicated email support, while U.S. exchange users have access to confidential reporting mechanisms.
Regulatory momentum driving changes
These updates come amid increasing regulatory clarity in the United States, where the Commodity Futures Trading Commission is asserting authority over prediction market derivatives and shaping how event-based contracts are governed.
Polymarket’s enhanced compliance framework reflects a broader industry shift toward transparency and institutional-grade infrastructure. As trading volumes in prediction markets continue to hit record highs, platforms that can demonstrate strong oversight and trust are likely to attract more institutional participants.
Overall, the move signals Polymarket’s effort to balance innovation with regulation, positioning itself as a more secure and credible platform in a rapidly evolving market.
