Interactive Brokers Statistics: AUM, Valuation, Revenues, Number of Users & More

Toni Vitali| Updated January 23rd, 2024

Interactive Brokers has been one of the most reputable and popular global brokers ever since being founded in 1978, but especially in recent years.

They are known for their global availability (with some exceptions), a wide selection of financial products from over 150 global markets, access to advanced trading tools, and reasonable fees.

All of this makes them mainly appealing to intermediate and advanced investors, but they have also made significant improvements in reaching beginner investors in recent years, quickly becoming one of the largest brokerage firms internationally.

In this article, we will dive deep into the numbers behind Interactive Brokers. Namely, we will explore their assets under management (AUM), number of users, revenue, and more. We will focus on the latest data but will also show how some of these metrics evolved over time.

Our goal is to provide you with valuable information about the platform, regardless of whether you are just thinking about joining it, are already using it, or are just curious. Let’s dive in!

Overview

Interactive Brokers was founded in New York, US, in 1978 by Thomas Peterffy, who is still the company’s chairman and largest shareholder. He emigrated to the United States from Hungary in 1965 and built the company intending to apply cutting-edge computer technology to automate trading and lower costs.

Today, Interactive Brokers is headquartered in Greenwich, Connecticut, with 2,900+ employees across its international offices in North America, Europe, and Asia.

They are also regulated by top-tier financial institutions in multiple countries, and the company is listed on the NASDAQ exchange under the ticker IBKR.

Ownership

Interactive Brokers is a public company, meaning its shares are traded on the stock market. However, only around 24.5% of the company is publicly held, while the remainder is held by their employees and affiliates, with the founder Thomas Peterffy being the largest shareholder at around 70% stake in ownership.

Some of the other major shareholders include Vanguard Group Inc., BlackRock Inc., Orbis Allan Gray Ltd, Kayne Anderson Rudnick Investment Management LLC, and more. (source: fintel.io)

Interactive Brokers Users

Interactive Brokers have shown steady growth in their user base over the years. We can see clearly that the events of 2020 (namely the COVID-19 pandemic) have caused a surge in user count, doubling between 2019 and 2021.

The growth in customer accounts hasn’t stopped since then, with Interactive Brokers currently (January 2024) having nearly 2.5 million users (22% growth from the year prior). This is especially impressive since they broke the 1 million user mark less than 3 years prior (in 2020).

Besides the pandemic (which was a boost for most financial platforms worldwide), Interactive Brokers made some adjustments to appeal to a wider investor base. Most notably, they abolished their monthly inactivity fee and minimum deposit requirement, as well as launched the beginner-friendly IBKR GlobalTrader App. These changes have significantly lowered entry barriers for beginner investors.

Interactive Brokers Assets Under Management (AUM)

With more users flocking to the platform, it was natural to expect a significant increase in assets under management (AUM). We can see similar trends here, with steady growth until 2020, when it exploded, more than doubling from 2019 to 2021.

The year 2022 wasn’t as good for most financial markets, so it was natural to see a significant year-over-year drop in AUM from 2021 to 2022 (nearly 18%). The trend was, however, reversed in 2023, with the AUM on the platform nearly reaching its all-time high by the end of Q3 2023.

As of December 2023, Interactive Brokers reported $426.0 billion in AUM.

Interactive Brokers Average Account Size

If we take into account assets under management and the number of customer accounts, we can work out the average account size per Interactive Brokers’ client.

This number has also been rising steadily over the years, breaking the $200,000 mark for the first time in 2014. The growth trend, however, peaked in 2020 at around $269,000, followed by a significant decline in the following years, nearly halving by Q3 2023.

This decline can be attributed to multiple factors, most notably to the significant influx of beginner investors and the rough year of 2022 for most financial markets.
