Comer expands prediction market insider trading probe

• House Oversight Chairman James Comer requested records from three prediction-market platforms.
• The letters target identity checks, geographic controls and suspicious-trading detection.
• The committee set October 13, 2026, as the deadline for requested documents.

Chairman James Comer has requested records from Hyperliquid Labs, Crypto.com and Aristotle Exchange in letters dated September 29.

The inquiry examines safeguards against insider trading involving nonpublic or classified government information.

“Americans deserve to know that these platforms are taking steps to prevent insider trading,” according to Chairman of the House Oversight Committee James Comer.

The letters seek details on identity verification, geographic restrictions and suspicious-trading detection procedures.

The committee requested documents covering activity from January 1, 2024, through the present.

The Hyperliquid letter also asks about event contracts involving rates, elections and geopolitical outcomes.

Crypto.com faces additional requests concerning employee trading restrictions and government officials using event contracts.

The letters extend the committee’s ongoing investigation into safeguards across online prediction-market platforms.
