James Comer widened a House Oversight probe on prediction-market insider trading to include Hyperliquid Labs, Crypto.com and Aristotle Exchange, the operator of PredictIt. The requests focus on identity checks, suspicious-trade monitoring and related records, and one coverage item says the letters were sent Sept. 29. One piece also says the committee asked for records tied to government insiders, employee trades and suspicious activity referrals.
