Prediction Markets Are Insider‑trading Vectors

A US special‑forces master sergeant was arrested for allegedly trading on classified information about an operation to capture Venezuela’s president, pocketing roughly $400,000 on Polymarket. This is the first US criminal case linking insider trading to commercial prediction markets and shows how such platforms can be used to monetize secret government intelligence. — The case creates a legal and policy precedent that could force new rules for prediction markets, change how platforms monitor trades, and heighten scrutiny on personnel with access to sensitive information.
