StockStory’s Take

Interactive Brokers’ fourth quarter was characterized by steady performance across its core brokerage and trading services, with results that met market expectations and left the stock largely unchanged. Management attributed the quarter’s growth to a combination of strong account additions, increased client equity balances, and higher trading activity across equities, options, and futures. CEO Milan Galik highlighted that the company added over one million net new accounts during 2025, representing record growth, and emphasized the expansion of client assets above $780 billion. The firm’s focus on offering broad market access, competitive pricing, and advanced trading tools drove higher client engagement and trading volume, especially as investors became more active in a volatile interest rate environment.

Looking ahead, Interactive Brokers’ management is prioritizing investments in technology, new product development, and expansion into additional global markets. The company expects continued account growth and increased trading activity as it introduces new features, such as enhanced AI-powered tools and expanded access to tax-advantaged accounts globally. CFO Paul Brody signaled that expense growth will remain disciplined but could increase with rising investments in artificial intelligence initiatives. Galik noted, “We have universally been attracting both large and small accounts, retail and institutional, for the same reasons—technology, fair pricing, and global access.”

Key Insights from Management’s Remarks

Management pointed to robust client activity, expansion of product offerings, and technology-driven enhancements as primary contributors to the quarter’s results. The diversification of revenue streams and growing international presence also played a key role.

• Record account growth: The company added over one million net new accounts during the year, with management attributing the surge to the global appeal of its platform and broad access to markets, supporting both retail and institutional clients.

• Client asset expansion: Client equity rose by 37% year over year, exceeding $780 billion for the first time, driven by existing client growth and strong new account acquisition across diverse geographies.

• Trading volume momentum: Options, futures, and equities volumes all saw double-digit percentage increases, with total daily average revenue trades (DARTs) up 30% compared to the prior year. Clients also made greater use of leverage, increasing margin loan balances.

• Platform and product innovation: Management highlighted ongoing investments in technology, including the launch of Global Trader 2.0, enhancements to the IBKR desktop platform, and the integration of AI-powered research tools and news summaries. The rollout of new tax-advantaged account types in multiple countries further diversified the product suite.

• Cost discipline and margin resilience: Despite increased advertising spend and modest compensation growth, Interactive Brokers achieved a pretax margin of 79%. Execution and clearing costs declined, benefiting from exchange rebates and a reduction in regulatory fees, helping preserve profitability.

Drivers of Future Performance

Management expects continued account expansion, deeper client engagement, and further product enhancements to drive growth in the coming quarters, even as expense discipline remains a focus.

• Global market expansion: The company plans to enter additional countries, building on recent launches in Brazil, Taiwan, the UAE, and Slovenia. Management believes this international focus will support further account growth and asset inflows.

• AI integration and platform upgrades: Ongoing investment in artificial intelligence is expected to enhance both client experience and operational efficiency. Management cited projects such as AI-powered investment themes and the Ask IBKR tool as differentiators that could drive user engagement and retention.

• Regulatory and expense management: While expense growth is projected to remain in line with recent trends, management acknowledged that new AI initiatives and compliance requirements in new geographies could push costs higher. The pursuit of a U.S. banking charter and potential European license may also introduce new regulatory complexity.

Catalysts in Upcoming Quarters

In the upcoming quarters, our analyst team will be watching (1) the pace of international account growth as new markets are added, (2) the adoption and engagement levels with new AI-powered platform features, and (3) progress toward securing U.S. and potential European banking licenses. Expansion of crypto and prediction market offerings, as well as disciplined cost management, will also be important markers for sustained performance.
