Introduction
Zack
I’m Zack Fuss and today we are breaking down Interactive Brokers, widely recognized as IBKR. Founded in 1978, Interactive Brokers evolved from a market maker on the American Stock Exchange to a global cutting-edge electronic brokerage firm. Its founder, Thomas Peterffy, remains its largest shareholder and is one of the wealthiest people in the world.
Peterffy immigrated to the US from Hungary, taught himself computer programming, pioneered automated trading, and played a crucial role in digitizing financial markets. Today, we’ll explore IBKR’s journey from Timberhill to a public company with a ~$80B market cap.
We’ll cover how IBKR earns revenue beyond commissions, including net interest income and market-making activities. We’ll discuss its reputation for low-cost access, global reach, sophisticated tools, and automated tech stack.
Guests: Freddy Lait and Jacopo di Nardo of Latitude Investment.
The Low-Cost Brokerage Revolution
Zack
Freddy, Jacopo, can we start with a broad view of the brokerage industry and where IBKR fits in?
Freddy
IBKR is a digital broker that started 50 years ago with a tech-first approach. They’ve built the lowest cost-to-serve, highest quality platform through automation. This results in:
- Highest profitability
- No advertising
- Explosive customer growth
They’re seeing compounded growth from:
- Other brokers introducing business
- Hedge funds and RIAs
- International expansion
Zack
What are IBKR’s key revenue streams?
Freddy
Two main sources:
- Commissions: ~$600/account/year from 3.5M accounts = ~$2B/year
- Net interest margin: ~11% of client assets on margin = ~$3B/year
Primary driver = account growth.
