The Biggest Stock Brokerage Firms in the US (2024)

The Big Four brokerage firms in the U.S. are Charles Schwab, Fidelity Investments, E*TRADE, and Vanguard. That's based on the sizes of their customer numbers and assets under management.

This list of the top brokerage firms is by no means static. TD Ameritrade was one of them until it was acquired by Charles Schwab in a deal that was finalized in 2020.

Below is a short analysis of each brokerage's products, services, and fee structures. They are listed in no particular order.

Key Takeaways

  • Charles Schwab has $8.56 trillion under management and 35 million active brokerage accounts.
  • Fidelity Investments is a good choice for customers who want to invest in Fidelity ETFs and mutual funds.
  • E*TRADE is an online brokerage pioneer, well-known for its full-featured mobile apps, top-notch options trading tools, and customizable user experience.
  • Vanguard offers its own ETFs and mutual funds with no added fees for online transactions.

Charles Schwab

  • Assets under management: $8.56 trillion
  • Number of accounts: 35 million

Charles Schwab was founded in 1971 and is based in San Francisco. It is one of the leading investment brokerages and IRA custodian firms in the U.S.

As of Feb. 14, 2024, Charles Schwab held $8.56 trillion in client assets, with a total of 35 million active brokerage accounts. It also operates Schwab Bank, one of the largest banks in the United States, which allows its brokerage clients to link their trading accounts with a checking account. The company boasted 1.9 million active banking accounts.

The firm offers clients a variety of investment products including stocks, mutual funds, exchange-traded funds (ETFs), money market funds, fixed-income products, options, futures, insurance, and annuities. Clients can invest in both Schwab's proprietary products and other third-party investments.

Charles Schwab's Fee Structure

Schwab, the country's first real discount brokerage, has consistently been rated one of the cheapest brokerage firms in the United States. In October 2019, Schwab cut commissions from $4.95 to $0.00 for all U.S.- and Canadian-listed stocks, ETFs, options online, and mobile trades. Online options trades have a standard $0.65 per-contract fee.

The operating expense ratio (OER) fees for actively managed mutual funds ranges from 0.22% to 1.25%. Fees for passively managed mutual funds can range from 0.02% to 0.39%. Annual portfolio management fees at Schwab start at 0.80% for the Schwab Private Client account. These fees decrease for clients with higher asset levels.

The firm also offers clients a worry-free, passive approach to investing through its robo-advisor service called Intelligent Portfolios. The online platform provides clients with an automated experience, giving them access to a series of ETFs that rebalance per the client's investment goals. The service requires a minimum $5,000 investment and comes with no advisory or commission fees.

In 2019, Charles Schwab announced the acquisition of TD Ameritrade in a stock transaction valued at approximately $26 billion. The accounts of TD Ameritrade clients were migrated to Schwab by the end of 2023.

Fidelity Investments

  • Assets under management: $12.6 trillion
  • Number of individual investors: 50 million

Fidelity Investments is the one of the nation's largest keepers of 401(k) retirement savings plans. Founded in 1946 as Fidelity Management & Research, the company is based in Boston.

According to the company's website, Fidelity had $12.6 trillion in customer assets as of December 2023, with 50 million individual investors.

Fidelity is the best choice for brokerage clients who also want to invest in Fidelity ETFs and mutual funds. The firm also offers investments in third-party products.

Fidelity Investments' Fee Structure

Fidelity touts its zero account fees and no minimums to open a retail brokerage account, including IRAs. Following Schwab's lead, Fidelity also offers commission-free stock, ETF, and options trades. Options trades also have $0 commissions, plus a standard $0.65 per-contract fee.

There are no minimums to invest in Fidelity mutual funds. Fidelity does not charge an expense ratio fee for certain proprietary mutual funds and offers hundreds of other funds with no transaction fees.

Portfolio advisory service fees range from 0.50% to 1.50% based on the amount invested. Minimum investments range from $50,000 to $500,000 based on the investment options. For its automated Fidelity Go service, the firm charges a 0.35% advisory fee for balances exceeding $25,000 but requires no account minimum to open an account.

Through its mutual funds and other advisory services, Fidelity has tens of millions of non-brokerage customers, something the others cannot claim.

E*TRADE (Morgan Stanley)

  • Assets under management: $360 billion.
  • Number of accounts: 5.2 million.

Founded in 1982, E*TRADE began as a holding company and has transformed into a leading online discount brokerage service. The company was hit hard during the 2007-2008 financial crisis because of high exposure to subprime mortgage portfolios. Its stock dropped 86.7% in 2007 before the company implemented a comprehensive turnaround plan.

The turnaround worked and E*TRADE has become a leading financial firm for its mobile accessibility, online trading tools, and customizable user experience. As of February 2020, E*TRADE had more than 5.2 million retail brokerage accounts with more than $360 billion in client assets. More recent information is not broken out by Morgan Stanley.

Just like the other top brokers, E*TRADE offers clients access to ETFs, mutual funds, stocks, options, and fixed-income products. The firm also offers two checking accounts and a savings account with $500,000 in FDIC insurance.

Clients can also choose a prebuilt portfolio, which gives them a diversified portfolio of mutual funds or ETFs built by an investment strategy team.

E*TRADE's Fee Structure

In 2019, E*TRADE joined Schwab and Fidelity in offering no-fee trading. E*TRADE cut commissions on stock, options and ETF trades to $0 each, while options contracts are charged $0.65 each ($0.50 with 30+ trades per quarter).

On February 20, 2020, investment banking firm Morgan Stanley announced it would acquire E*TRADE in an all-stock transaction valued at approximately $13 billion. The acquisition closed in October of 2020.


  • Assets under management: $8.2 trillion.
  • Number of accounts: 50+ million.

Started by John Bogle in 1974, Vanguard's business model is unique in that it is owned by its investors. Those who invest in funds managed by the firm become owners of the company. Well-known for its role in creating indexed mutual funds for individual investors, the brokerage was quickly mimicked by other firms.

Vanguard was among the first to adopt an online portal for investors in 1995, allowing investors access to accounts, services, and educational materials.

Vanguard's Fee Structure

Vanguard has always been proud of its low-fee services. It offers ETFs and mutual funds with no additional fees for online transactions, although there are expense ratios for managing the funds.

Options exercises and assignments are $1 per contract for accounts with less than $1 million, $0 for the first 25 trades, and $1 for all trades after that (accounts of $1 to $5 million). Accounts with more than $5 million are charged $0 for the first 100 trades, and $1 per contract for all following contracts.
