Polymarket tightens rules to combat insider trading

Polymarket has tightened trading rules, banning insider trading and manipulative practices. The reforms introduce strict violation categories and advanced monitoring to ensure integrity.

Polymarket has implemented significant reforms to its trading rules on both its decentralized platform and its CFTC-regulated U.S. exchange. These changes are designed to strengthen market integrity and align with regulatory requirements. The updated framework strictly bans insider trading, categorizing violations into three types: trading on confidential or illegally obtained information, acting on tips acquired unlawfully with knowledge of their origin, and trading by individuals who can influence event outcomes. These rules are now formally documented in operational rulebooks to ensure consistency for all users. Polymarket has also broadened its prohibitions on manipulative practices, such as spoofing, wash trading, self-dealing, fictitious transactions, and front-running. Enhanced monitoring systems and formal reporting channels for suspicious activity have been introduced, leveraging blockchain transparency and surveillance technology to reinforce compliance. These measures aim to maintain trust and fairness across all trading activities following recent public scrutiny.
