[U.S. Lawmakers Propose Legislation to Ban Officials from Using Prediction Markets for 'Insider Trading'] According to The Block, U.S. Congressman Ritchie Torres plans to introduce the '2026 Financial Prediction Market Public Integrity Act,' which would prohibit federal officials from participating in political prediction market trading when in possession of significant non-public information. The proposal stems from concerns over insider trading after a Polymarket account bet on the ousting of Maduro prior to a U.S. military raid to arrest him, turning $32,500 into over $400,000 in profit. In 2025, the total trading volume of prediction markets reached $44 billion.
