DOJ charges two ex-Robinhood engineers with front-running Hyperliquid listings

This is a notable shift in how insider-trading enforcement reaches crypto: the alleged edge came not from confidential issuer information but from a brokerage's own listing pipeline, with positions taken on a separate venue. It puts listing desks and the engineers who touch pre-announcement data squarely in scope, and it raises the question of whether exchange and DEX listing calendars become treated as material non-public information. Whether prosecutors can make that theory stick beyond this pair is the open question.
