Cash App

Cash App is a peer-to-peer mobile payments app launched by Block, Inc. (formerly Square) in 2013 as a way to send and receive money via phone. In 2019, the company introduced Cash App Investing — a zero-commission brokerage service that lets users buy fractional shares of stocks and ETFs through the same interface they use to send money to friends or buy goods through Cash App Pay. As of 2024, Cash App has over 55 million monthly active users, with Cash App Investing accounting for a meaningful share of first-time retail investors entering the stock market. Cash App Investing LLC is a wholly owned subsidiary of Block, Inc., and is a FINRA-registered broker-dealer.

The platform's value proposition is frictionless simplicity. Users can invest as little as $1 in fractional shares of any stock or ETF listed on U.S. exchanges, with no account minimums, no trading fees, and no inactivity penalties. Cash App Investing supports over 8,000 individual securities and offers auto-invest on a recurring schedule, making it especially appealing for dollar-cost averaging strategies. The integration with Cash App's banking and payments features — including the Cash App Card, direct deposit, and peer-to-peer transfers — makes it easy for users to move money fluidly between cash, stocks, and everyday spending without needing multiple accounts or apps.
