Kalshi's CEO supports legislation banning insider trading in prediction markets, stating that the platform has already implemented the relevant rules.

Tarek Mansour, CEO of prediction market platform Kalshi, expressed support for the "Public Integrity Financial Prediction Markets Act of 2026" promoted by U.S. Representative Ritchie Torres, which aims to prohibit insider trading in prediction markets. Mansour pointed out that Kalshi has already implemented measures prohibiting insider trading in its platform rules. The bill would prohibit elected federal officials, political appointees, and executive branch employees from participating in prediction market transactions involving government policies, government actions, or political outcomes. The legislation is related to recent market controversy: accounts on the decentralized prediction market Polymarket bet on Venezuelan President Maduro's impeachment by the end of January, subsequently profiting approximately $400,000, raising concerns about trading using inside government information. Mansour emphasized the need to distinguish between prediction market platforms regulated in the U.S. and unregulated overseas platforms. He stated that Kalshi, as a federally regulated platform, employs insider trading rules similar to those of the New York Stock Exchange and Nasdaq, prohibiting users with access to non-public information from participating in related market transactions. He also pointed out that the bill only applies to regulated platforms within the United States, and the current controversy mainly focuses on unregulated platforms outside the US. Data shows that in December 2025, both Kalshi and Polymarket reached record monthly trading volumes, with Kalshi at approximately $6.26 billion and Polymarket at approximately $2.28 billion. Kalshi has consistently led in trading volume since March 2025. (The Block)
