Rep. Comer Targets 3 Platforms in Expanded Prediction Market Probe

House Oversight Chairman James Comer expanded the prediction market insider trading probe to Hyperliquid, Crypto.com, and Predictit, demanding records by Oct. 13. The inquiry follows allegations that a U.S. Army master sergeant earned over $409,000 betting with classified intelligence on Polymarket. Lawmakers are also examining a suspiciously timed $1.1 billion leveraged crypto trade.
