Kalshi CEO Tarek Mansour supports the U.S. 'Public Integrity Financial Prediction Markets Act of 2026' that aims to ban insider trading in prediction markets. Mansour emphasized that Kalshi, as a federally regulated platform, already enforces strict insider trading rules similar to major stock exchanges. The bill targets regulated U.S. platforms and officials, while concerns persist over unregulated overseas markets like Polymarket, which saw significant trading volumes recently.
