DOJ Charges Two Robinhood Engineers with Front-Running Crypto Listings on Hyperliquid, Marking New Phase in US Crypto Insider Trading Enforcement
The US Department of Justice announced on September 15 criminal charges against two Robinhood engineers, alleging that between 2025 and 2026 they used inside information about the company’s upcoming crypto asset listings to take front-running positions on Hyperliquid decentralized perpetual contract exchange, with illegal profits potentially reaching several million dollars. This case represents the first criminal charge by US judicial authorities for insider trading conduct on a decentralized finance (DeFi) protocol, and will have profound effects on DeFi regulation, on-chain transaction privacy, and US crypto industry compliance architecture.
