Odaily Planet Daily News: Tarek Mansour, CEO of prediction market platform Kalshi, expressed support for the “Public Integrity Finance Prediction Market Act of 2026” promoted by U.S. Representative Ritchie Torres, which aims to prohibit insider trading activities in prediction markets. Mansour pointed out that Kalshi has already implemented measures to prohibit insider trading in its platform rules.
According to the introduction, the bill will prohibit federal elected officials, political appointees, and administrative department employees from participating in prediction market trades involving government policies, government actions, or political outcomes. The legislative background is related to recent market controversies: previously, an account on decentralized prediction market Polymarket bet that Venezuelan President Maduro would be removed from office before the end of January, and earned approximately $400,000 in profits after the related event occurred, raising concerns about trading using government internal information.
In his statement, Mansour emphasized the need to distinguish 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 related market trades. At the same time, he pointed out that the bill only applies to regulated platforms on U.S. soil, with current controversies mainly concentrated on non-U.S., unregulated platforms.
Data shows that in December 2025, both Kalshi and Polymarket achieved record-high monthly trading volumes, with Kalshi at approximately $6.26 billion and Polymarket at approximately $2.28 billion. Since March 2025, Kalshi’s trading volume has maintained a leading position. (The Block)
