US Investigates Prediction Markets for Insider Trading

The House Oversight Committee, led by Chairman James Comer, is intensifying its probe into potential insider trading within prediction markets, targeting companies such as Crypto.com, Hyperliquid, and PredictIt.

Lawmakers have issued requests for internal data, including user identification methods and algorithms to identify suspicious activities. Each company faces tailored inquiries; for instance, Crypto.com must disclose whether its employees engaged in trading based on non-public information about token listings.

Hyperliquid is under scrutiny for a significant short position taken by a trader shortly before the U.S. announced tariff changes, with the committee probing how the firm tracks account ownership and reporting of suspicious transactions.

PredictIt is being questioned about bets placed by officials concerning elections and government policies. Comer's investigation aims to shed light on potential exploitation of confidential information as the prediction market sector grows.

Initiated in May, the inquiry has already seen substantial engagement from the industry, with firms like Kalshi and Polymarket also receiving similar requests for documentation. Over 1,000 documents have been submitted, alongside multiple confidential discussions with the committee. Notably, the New York City Council is conducting its own review of Polymarket and Kalshi's marketing tactics, especially concerning their outreach to younger audiences.
