House Oversight targets Hyperliquid, Crypto.com and PredictIt in insider trading probe

House Oversight Committee Chairman James Comer widened his insider trading probe of prediction markets on Tuesday, sending document requests to Hyperliquid Labs, Crypto.com and Aristotle Exchange Inc., owner of PredictIt, CNBC reported. He asked how each platform verifies users and detects and reports trades based on nonpublic information. He cited a reported leveraged short on Hyperliquid within minutes of an October 2025 tariff announcement; on Oct. 10, 2025 a trader made about $192 million after Trump announced 100% tariffs on Chinese imports. Former BitForex CEO Garrett Jin, linked to the position by an onchain sleuth, denied any ties to Trump or insider trading.
