US lawmakers have introduced the Public Integrity in Financial Prediction Markets Act of 2026, aiming to prevent government officials from using non-public information to profit from platforms like Kalshi and Polymarket. The bipartisan bill reflects growing concern that prediction markets could be exploited for insider-style trading.

If passed, the legislation would apply to a wide range of officials, including the president, members of Congress, and federal employees. It represents a major step toward regulating a fast-growing sector that blends finance, politics, and betting.
