Comer has sent a letter to Hyperliquid CEO Jeff Yan citing a leveraged short position on the platform tied to an October 2025 tariff announcement. The correspondence highlights concerns that the trade was established before the tariff news became publicly known. The inquiry focuses on whether non-public information influenced the positioning, raising questions about market integrity and information asymmetry on the decentralized exchange. Comer is seeking clarification from Yan regarding the circumstances surrounding the trade and the platform's oversight mechanisms.
