Charles Schwab continues to sit at the top of the list of largest brokerage firms. It leads the major online stock brokers with over $7.6 trillion in assets under management (AUM). In addition, its number of clients has shot up by 127% over the last year after finishing the acquisition of TD Ameritrade.
After a rollercoaster of a year where the COVID-19 pandemic sent securities prices tumbling, stock brokers saw significant growth in 2021. The market recovery resulted in major increases in broker assets and client numbers.
It’s not just the biggest stock brokers that have been successful. Robinhood is extremely popular for its modern design and for pioneering no-commission trading, and Coinbase rode the success of the crypto market to massive gains.
(Editor's note: we realize Coinbase isn't a brokerage firm, but its amazing growth numbers are worth mentioning here to show the increasing popularity of cryptocurrency investing.)
Keep reading for all the most recent stock broker data and industry trends.

The largest brokerage firms by assets and users
Some brokers posted record numbers in 2021 while others had more muted gains. Here's the asset and client data for several of the biggest brokerage firms and the crypto exchange Coinbase.
Assets under management
A stock broker’s assets under management (AUM) is the total amount of client assets it has. This is a good way of comparing the size of different brokers.
The numbers below are each broker’s AUM in September of 2020 and 2021, with one exception. Robinhood’s numbers are from March of 2020 and 2021, because those are what it provided in its IPO filing.

Platform | Assets under management 2020 (trillions) | Assets under management 2021 (trillions) | Change |
---|---|---|---|
Charles Schwab | $4.395 | $7.614 | 73% |
Fidelity | $3.500 | $4.228 | 21% |
Bank of America/Merrill Lynch | $3.067 | $3.693 | 20% |
J.P. Morgan | $2.564 | $3.00 | 17% |
Robinhood | $0.19 | $0.81 | 321%* |
Coinbase | $0.36 | $0.255 | 608% |
Ally Invest | $0.11 | $0.16 | 42%* |
The old guard still has a dominant market share, but Robinhood and Coinbase have seen explosive growth over the last year.
Coinbase, for example, grew its assets under management by 608% from September 2020 to 2021. That was over five times as much as any of the traditional stock brokers. However, Coinbase is also dependent on the volatile crypto market. If cryptocurrency slows down or declines in value, it will have a considerable impact on the crypto exchange.
Robinhood reported growth of 311% from March 2020 to 2021 in its IPO filing. This stock broker also offers crypto, and its crypto assets grew from $480 million to $11.6 billion. But the broker isn't reliant on crypto, as its equities also grew from $13.5 billion to $65 billion.
Despite their success, both platforms have a long way to go to catch up to more established brokers, all of which reported over $1.5 trillion in assets under management.
Client accounts
Not all brokers release their exact client numbers. Here are the most recent numbers for the ones that did:

Platform | Number of accounts in 2020 | Number of accounts in 2021 | Change |
---|---|---|---|
Coinbase | 39,000,000 | 73,000,000 | 87% |
Charles Schwab | 14,393,000 | 32,675,000 | 127% |
Fidelity | 25,122,000 | 30,900,000 | 23% |
Robinhood | 7,200,000 | 18,000,000 | 150% |
Ally Invest | 445,000 | 503,000 | 13% |
Cryptocurrency is extremely popular. Case in point, Coinbase, which has 73 million accounts. Thanks to substantial growth in clients over the last year, Charles Schwab came in second with over 32.5 million.
When we compare client numbers with AUM, we can also see that traditional brokers tend to have much wealthier clients. Even knowing this, each broker’s average assets per client may surprise you:

Broker | Average assets per client |
---|---|
Charles Schwab | $233,022 |
Fidelity | $136,828 |
Ally Invest | $32,386 |
Robinhood | $4,576 |
Coinbase | $3,493 |

- Clients: 18 million
- Monthly transacting users: 17.7 million
Although it hasn't been around long, Robinhood has had a huge impact on the investment industry. It was founded in 2013 and made waves for offering zero-commission trading. That may have seemed like a gimmick at the time, but at this point, it has become the industry norm. Robinhood also made waves in January 2018 when it started listing cryptocurrency.
Robinhood isn't a full-service broker, as it only offers individual accounts. There aren't any other account types -- such as retirement accounts -- available. Despite lacking some features compared to the major brokers, Robinhood is an extremely popular trading platform, especially among younger investors.

Vanguard
- Assets under management: About $7.2 trillion
- Clients: Over 30 million
Vanguard is one of the most popular full-service stock brokerages for investing in mutual funds and exchange traded funds (ETFs). It wasn't included in the earlier data sets because the asset and client information it provides aren't as detailed as what other brokers offer.
The numbers above were reported by Vanguard as of Jan. 31, 2021. Although investors primarily use it for index fund investing and not for everyday stock trading, it manages more assets and has more clients than most of its competitors.

Coinbase

Although Coinbase has a very large user base, it has a much lower number of users who make transactions on a monthly basis. Per its most recent numbers, just a little over 10% of its total clients are monthly transacting users.
