US Congress Expands Prediction Market Insider Trading Probe to Hyperliquid and Crypto.com

The House Committee on Oversight and Government Reform has expanded its investigation into insider trading on prediction markets, issuing inquiries to Hyperliquid, Crypto.com, and Aristotle Exchange. Chairman James Comer is seeking information on customer identification, geolocation, and suspicious activity reporting. This follows an initial phase targeting Kalshi and Polymarket, as Congress intensifies scrutiny over the use of nonpublic information for betting.
