Kalshi CEO supports legislation to ban insider trading in prediction markets, stating that the platform has already implemented relevant rules in advance

Odaily Planet Daily reports that the prediction market platform Kalshi’s CEO Tarek Mansour expressed support for the “2026 Public Integrity Financial Prediction Market Act,” proposed by U.S. Representative Ritchie Torres, which aims to prohibit insider trading in prediction markets. Mansour pointed out that Kalshi has long implemented anti-insider trading measures in its platform rules.

According to reports, the bill will prohibit federal elected officials, political appointees, and administrative agency employees from participating in prediction market transactions involving government policies, government actions, or political outcomes. The legislative background relates to recent market controversies: previously, on the decentralized prediction market Polymarket, an account bet that Venezuelan President Maduro would be ousted before the end of January, and after the event, the account earned about $400,000, raising concerns about trading based on government insider information.

Mansour emphasized that there should be a distinction between U.S.-regulated prediction market platforms and unregulated overseas platforms. He stated that Kalshi, as a federally regulated platform, has adopted insider trading rules similar to those of the New York Stock Exchange and NASDAQ, prohibiting users with non-public information from participating in relevant market transactions. He also pointed out that the bill applies only to U.S.-based regulated platforms, and current disputes mainly focus on non-U.S., unregulated platforms.

Data shows that in December 2025, the monthly trading volume of Kalshi and Polymarket both hit record highs, with Kalshi at approximately $6.26 billion and Polymarket at approximately $2.28 billion. Since March 2025, Kalshi’s trading volume has continued to lead. (The Block)
