The U.S. Commodity Futures Trading Commission has charged former employee David Miller with insider trading, alleging that he used confidential information gained during his employment to trade shares of prediction market platforms Polymarket and Kalshi. According to the complaint, Miller exploited nonpublic information, which gave him an unfair advantage over other investors by trading shares before their official public market releases. The charges underscore growing regulatory attention on the compliance and integrity of emerging prediction markets. The CFTC's enforcement action reflects ongoing efforts to police insider trading activities in innovative financial markets that merge elements of gaming and trading platforms. At present, the case remains under investigation as regulators seek to uphold market fairness and transparency.
