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.

In a zero-commission world, how does IBKR thrive?

Direct market access (no middleman)
No payment for order flow (PFOF), better execution for customers
Lower commissions, cheaper margin loans, better cash yields
Automation = lower opex → reinvest in price reductions
