Interactive Brokers reported fourth‐quarter revenue of $1.64 billion, a 21% increase year over year, driven by a 22% rise in commission revenue to $582 million and a 20% lift in net interest income to $966 million. The automated global platform processed year‐over‐year growth in customer trading volume of 27% in options, 22% in futures, and 16% in equities. Customer accounts reached 4.4 million, up 32% from the prior year, while non‐GAAP earnings per share climbed 27%.

For the full year 2025, client equity advanced 37% to $780 billion, a $200 billion increase over 2024, as Interactive Brokers added more than 1 million net new accounts. Trading activity across all product lines remained robust, supporting sustained commission and interest income growth. Over the past five years, the company’s share performance has appreciated by over 340%, underscoring its compounding growth profile.

Interactive Brokers trades at a price‐to‐earnings ratio of approximately 34, reflecting its premium growth status. Key risks include potential downturns in market volatility that could dampen trading volumes and account additions, and the possibility of declining interest rates that would compress net interest income. Should either occur, revenue growth and profitability could slow abruptly, leading to heightened share‐price volatility.

Investors looking to establish or add to a position may consider selling out‐of‐the‐money put options with strikes below the current valuation consensus. This strategy generates premium income today while obligating the writer to purchase shares at a lower effective cost basis if assigned. Given the company’s strong account growth and cash generation, this trade offers a disciplined way to secure exposure at a discount, provided one is comfortable with potential assignment and the associated capital requirement.
