Robinhood Markets, the go-to trading app for young investors, wants its user base to get even younger.

The digital brokerage is kicking off a nationwide marketing campaign Wednesday that is designed to turn more college students into Robinhood customers. Robinhood will give students who sign up for brokerage accounts using their school email address $15 to trade, and enter them into a $20,000 giveaway. Robinhood executives will tour campuses of community colleges and historically black colleges and universities this fall.
