Robinhood $HOOD just rolled out perpetual futures trading on their platform. This is a significant expansion beyond spot trading—perps let traders take leveraged positions without expiration dates, which has been a core feature on crypto exchanges for years. Robinhood's clearly making a play to capture more active traders and compete directly with platforms like Coinbase and traditional derivatives brokers. The move could drive higher trading volumes and revenue per user, but also brings regulatory scrutiny and risk management challenges. Worth watching how retail adoption plays out here.
