Kalshi CEO Tarek Mansour this week voiced full support for a new U.S. bill aimed at criminalizing insider trading on prediction market platforms. Introduced by Representative Ritchie Torres, the proposed legislation is formally named the Public Integrity in Financial Prediction Markets Act of 2026. Mansour stated that Kalshi already enforces insider trading rules comparable to those of the NYSE and Nasdaq, making the bill a natural reinforcement of existing practices.
Bill Details: Banning Bets on Sensitive Government Information
The bill would prohibit federal elected officials, political appointees, and executive branch employees from wagering on prediction markets concerning government actions, policies, or political outcomes. Its goal is to prevent abuse of non-public information and safeguard public trust. Mansour emphasized that Kalshi, as a federally regulated exchange, already blocks users who possess insider information from trading — a standard not applied by offshore platforms.
The $400K Polymarket Bet That Triggered Action
Legislative momentum accelerated after a $400,000 bet on Polymarket that Venezuelan President Nicolás Maduro would be removed by the end of January. The trade was placed just before Maduro’s capture, raising serious insider trading suspicions. The incident fueled broader debate about unregulated prediction markets and their potential threat to political integrity.
Kalshi Distances Itself from Offshore Platforms
Mansour used the opportunity to draw a clear line between Kalshi and offshore platforms like Polymarket. Kalshi is federally regulated, while offshore competitors operate without equivalent legal obligations. He criticized media reports for equating U.S.-regulated sites with unregulated foreign ones. Since March 2025, Kalshi has grown to become the largest prediction exchange by volume — $6.26 billion in December alone, compared to Polymarket's $2.28 billion.
Regulation Catches Up to Booming Prediction Markets
Industry giants like Crypto.com, Gemini, and DraftKings are entering the prediction market space, prompting U.S. regulators to push for stronger guardrails. For regulated platforms such as Kalshi, the new bill could enhance credibility. Offshore platforms, however, may face tougher scrutiny ahead. As political betting gains popularity, lawmakers demand greater market integrity and stricter information abuse prevention.
