Polymarket releases new market ethics rules, strengthening bans on insider trading and manipulation.

PANews reported on March 23 that prediction market platform Polymarket announced updates to its Market Integrity rules for its DeFi platform and its US-regulated exchange under the CFTC, and launched a dedicated Market Integrity page. The new rules explicitly prohibit three types of insider trading: trading using stolen confidential information, trading based on illegally leaked information, and contract trading by participants who can influence the outcome of events. In addition to insider trading, the rules prohibit fraud, market manipulation (including wash trading, wash trading, and fake transactions), self-trading, front-running, information abuse, and disrupting market order. Polymarket conducts on-chain multi-layered monitoring and collaborates with risk control technology service providers for auditing, and can block addresses and refer cases to law enforcement agencies. Its US platform collaborates with the NFA to implement a three-tiered transaction monitoring and enforcement system; violators may face suspension, termination, fines, or referral to regulatory/judicial authorities.
