Robinhood is a free, multiplatform stock trading app with over 10 million active users. It was founded in 2013 by Vladimir Tenev and Baiju Bhatt to provide accessible investing for all. While Robinhood does not charge trading commissions, it earns revenue through sources like Robinhood Gold subscriptions, interest on cash balances, and selling order flow to high-frequency traders. With its large, young user base of individual investors, Robinhood faces competition from traditional brokerages catering to both large and small accounts. There are some concerns about whether Robinhood can sustain its business model and continue innovating over the long run.
