Stock Trading & Investing App Revenue and Usage Statistics (2022)

David Curry

Updated: May 4, 2022

Like several other app industries, stock trading and investment saw a huge spike in usage during the coronavirus pandemic. Millions of people stuck at home were able to take advantage of new zero-commission mobile apps to trade shares, indexes and options.

Robinhood led the way with zero-commission in the US and has been the lead platform used by those investing in the “meme stocks”, like GameStop and AMC Entertainment. This pattern of investment was followed in other apps, which led to several platforms banning the trading of these stocks.

Larger investment platforms, such as Charles Schwab and E-Trade in the US, have both lowered commissions to better compete with Robinhood. Other features, like fractional shares and interest on balance, have also been added.

In the UK and Europe, several startups such as Trade Republic and Freetrade are attempting to become the European Robinhood, while older platforms like eToro and Plus 500 have lowered their fees to better compete.

Almost all of these zero-commission platforms use a process called payment-for-order-flow (PFOF) to generate income. The process bundles thousands of trades and directs them to a market maker, which will then compensate the stockbroker for it.

This process is controversial, as it was pioneered by Bernie Madoff, responsible for the largest Ponzi scheme in history. However, Robinhood and other operators have said the process allows zero-commission stock trading apps to exist.

In the UK, the process has been banned. Freetrade and other platforms generate most of their income through foreign exchange and premium subscription services. The European Union and US FTC are both looking into PFOF legality.

We are specifically focused on commission-free stock trading, which was pioneered by Robinhood and is now available through a myriad of platforms. As most stockbrokers in the US and some in the UK have removed commission fees (which were $7 a trade pre-Robinhood), we have tried to properly account for all of the value generated on these apps as well.

As most platforms generate a considerable amount of their app revenue through payment-for-order-flow, we have used this metric to collect financial data in the US and EU, alongside other financial data. For the UK, we have used other metrics, as payment for order flow it banned.

Stock Trading App Revenue

This chart only tracks stock trading revenue, which is derived from trade execution and the various fees stockbrokers attach to it. Savings funds, wealth management and other financial services connected to the stock trading platform are not included.

Year Revenue
2016 $3.2 billion
2017 $3.8 billion
2018 $4.8 billion
2019 $6.3 billion
2020 $10.9 billion

Stock Trading App Revenue by App

As with the previous chart, values are from stock trading revenue and fees attached to it. For this reason, Robinhood is much closer in revenue to stockbrokers like Charles Schwab and TD Ameritrade than it would be if all of their collective revenue was included.

Stock Trading App Users

The number of retail investors using mobile apps has steadily increased, with a surge in 2020 due to the coronavirus pandemic and the rise of meme stocks. Users are expected to increase to over 150 million in 2021.

Year Users
2016 28.9 million
2017 35.6 million
2018 44.8 million
2019 61.9 million
2020 91.5 million

Stock Trading App Users by App

Side-by-side comparisons of each app is difficult, as some stockbrokers record all users, while others only include active customers. Also, most Charles Schwab and TD Ameritrade customers do not use the company’s mobile apps.

Stock Trading App Users in US

The US has one of the highest rates of adoption for stock trading, with over 50 percent of the population owning stocks. The proliferation of zero-commission stock trading apps has also enticed a new generation into stock trading at a younger age.

Stock Trading App Users in Europe

In Europe, the percentage of people who have invested in stocks in far lower, with Estonia the only country with over 50 percent involvement. In most countries, 15 to 35 percent of households have invested in stocks.

Stock Trading App Valuations

We have decided to add the valuations of all companies which receive the majority of their income through stock trading, which does not include Charles Schwab or TD Ameritrade.
