House Oversight Chairman James Comer expanded his committee’s trading practices investigation on Sept. 29 by issuing formal record requests to Crypto.com, Hyperliquid Labs, and PredictIt operator Aristotle Exchange. The congressional inquiry seeks comprehensive documentation regarding customer verification procedures and systems designed to detect suspicious trading activity.
Federal Indictment Triggers Expanded Congressional Investigation
The investigation gained momentum following federal prosecutors’ April indictment of U.S. Army Master Sgt. Gannon Ken Van Dyke. Authorities claim he exploited classified intelligence regarding Operation Absolute Resolve to execute strategic wagers on Polymarket. Federal charging documents indicate the transactions yielded $409,881 in profits. Van Dyke entered a not guilty plea to all charges.
Lawmakers initiated their examination in May by requesting materials from Polymarket and Kalshi. Committee staff report they have reviewed approximately 1,000 documents and conducted five formal briefings with platform representatives. Recent CFTC warnings on prediction markets emphasized the need for stronger oversight mechanisms in venues where participants may possess information advantages unavailable to the broader trading community.
Detailed Documentation Demands Sent to Crypto.com
Congressional investigators directed Crypto.com to clarify operational distinctions between verification protocols used on its international exchange platform versus those employed by Crypto.com Derivatives North America. The formal request encompasses documentation on territorial trading restrictions, suspicious activity reports filed with regulators, and internal compliance frameworks governing staff members who receive early notification of token listings, asset custody changes, or pending regulatory developments.
The committee specifically requested details about federal employees or public officials who executed trades involving cryptocurrency regulation-related contracts. Legislators asked Crypto.com to outline existing policies designed to monitor customers whose professional responsibilities might provide access to material nonpublic information.
Hyperliquid received targeted inquiries after committee members referenced a reported $1.1 billion leveraged short position established across Bitcoin and Ether markets. Investigators noted the position launched approximately 30 hours ahead of President Trump’s October 2025 tariff policy announcement and subsequently produced profits surpassing $150 million. In related developments, Kalshi denied reports of a CFTC probe examining unusual trading patterns on its Ether perpetual futures market.
PredictIt Receives Demands for Compliance Documentation
PredictIt faces requirements to deliver records detailing customer identity verification systems, suspicious trading pattern reviews, political outcome contracts, and regulatory referral procedures. Congressional investigators also requested analysis showing how elimination of per-contract trader limitations under CFTC Letter No. 25-20 affected market liquidity, transaction volumes, or surveillance capabilities.
The committee established Oct. 13 as the submission deadline for all requested materials while also scheduling a briefing session with PredictIt staff members. CFTC crypto guidance demonstrates regulatory agencies are enhancing supervisory frameworks as digital asset markets continue expanding.
Committee leadership indicated they will analyze newly submitted documentation before determining whether additional legislative or investigative measures are warranted. The record requests span the period beginning Jan. 1, 2024, through the current date.
