Robinhood Markets, Inc. is an American financial services firm based in Menlo Park, California, that is most known for pioneering commission-free stock, ETF, and cryptocurrency trading with a mobile app launched in March 2015. Robinhood is a FINRA-regulated broker-dealer that is also a member of the Securities Investor Protection Corporation. It is also registered with the US Securities and Exchange Commission.

Interest gained on clients' cash balances, selling order information to high-frequency traders (a practice for which the SEC started an inquiry into the firm in September 2020), and margin lending is the three primary sources of revenue for the company. For the first three months of 2021, revenue more than quadrupled year over year to $331 million. Robinhood has 31 million users and 1.6 million individuals on its cryptocurrency wallet waitlist as of 2021.
