Robinhood was one of the first large online broker to offer free trading in stocks and ETFs in 2013 when its app officially launched. Since then, many brokerages have followed suit, including Charles Schwab, Fidelity, Merrill Edge, E*TRADE, Interactive Brokers, TD Ameritrade, Webull, J.P. Morgan, Vanguard, SoFi, and Ally Invest (among others). Note that many of these platforms still charge commissions for trading in OTC stocks, options, futures, or other non-stock securities.
