US House of Representatives proposes legislation to ban insider trading in market predictions.

[US Representative Proposes Legislation to Ban Insider Trading in Prediction Markets] According to Mars Finance, US Representative Ritchie Torres will introduce the "Public Integrity Act of 2026 for Financial Prediction Markets," which would prohibit federal officials from using material non-public information to trade in prediction markets. This move stems from a controversial incident: a Polymarket account created last December placed bets of approximately $32,500 on the Venezuelan situation, and within 24 hours of Maduro's arrest by US forces, it profited over $400,000, a return of over 1200%. The account made only four predictions, all related to US intervention in Venezuela, and the market began to rise hours before Trump's announcement, raising questions about insider trading. The bill would extend the STOCK Act principles to prediction markets, which are projected to have a trading volume exceeding $44 billion by 2025.
