Under increasing regulatory scrutiny, prediction market platforms Kalshi and Polymarket are implementing new measures to prevent insider trading and market manipulation. Kalshi has introduced screening tools to block political candidates from trading on their elections and uses integrity monitoring lists to prevent insiders from the sports industry from trading related events. Additionally, Kalshi has added a reporting feature to make it easier for users to report suspicious activities. Polymarket has updated its rules on its decentralized platform and the platform regulated by the U.S. Commodity Futures Trading Commission (CFTC), explicitly prohibiting trading based on stolen information, illegal insider tips, and individuals who can influence event outcomes. It also bans false quotes, money laundering, and other illicit activities. Meanwhile, U.S. senators have proposed a bill to prohibit offering prediction contracts related to sports or casino games on registered platforms.
