On March 23, Polymarket announced updates to its DeFi platform and market integrity rules for its U.S. exchange regulated by the Commodity Futures Trading Commission (CFTC). The revised rules are now included in the platform’s Terms of Use and U.S. rulebook, reinforcing restrictions on insider trading and market manipulation while improving transparency.

Core Rule Updates on Insider Trading

The updated framework defines three prohibited behaviors: trading based on stolen confidential information, using improperly disclosed insider information, and participating in markets where the user has influence over event outcomes. These measures aim to reduce risks caused by information asymmetry.

Market Integrity and Regulatory Alignment

Polymarket’s update reflects a broader trend of DeFi platforms aligning with traditional financial regulatory standards. Under CFTC oversight, platforms must ensure fair trading conditions and transparency, preventing manipulation that could disrupt market stability. This signals a shift toward stricter compliance in crypto prediction markets.
