Interactive Brokers is worth approximately $127 to $133 billion as of mid-February 2026, based on its current market capitalization. With shares of IBKR trading around $74.79 as of February 14, 2026, the electronic brokerage giant has seen its valuation surge roughly 53.5 percent over the past year alone. To put that in perspective, if you had invested $10,000 in IBKR stock at the low end of its 52-week range near $32.82, that position would have more than doubled. The company’s worth reflects not just its stock price but a business generating nearly $10 billion in annual revenue with profit margins that most financial firms can only dream about.
But a company’s market cap only tells part of the story. Interactive Brokers, founded by Thomas Peterffy in 1978, has built one of the most efficient brokerage operations in the world, and its recent financial results suggest the market may still be catching up to its actual earning power. In the fourth quarter of 2025, the firm posted record pre-tax margins of 79 percent and grew its customer base past 4.4 million accounts. This article breaks down exactly how Interactive Brokers reached its current valuation, what its earnings reveal about the business underneath the stock price, how analysts view its future, and what investors should weigh before deciding whether IBKR is fairly valued at these levels.

How Much Is Interactive Brokers Actually Worth on the Stock Market?
Interactive Brokers trades on the nasdaq under the ticker IBKR, and its market capitalization sits in the range of $127 to $133 billion depending on the exact day and data source. That figure is calculated by multiplying the share price — approximately $74.79 as of February 14, 2026 — by the total number of outstanding shares. The stock has been on a remarkable run, with a 52-week range stretching from $32.82 on the low end to $79.18 at the high. In January 2026 alone, IBKR shares gained 16.4 percent, a month that outpaced many large-cap tech stocks. To compare, Interactive Brokers’ market cap now places it among the largest publicly traded brokerage and financial services firms in the world.
Charles Schwab, which merged with TD Ameritrade, operates at a larger overall scale in terms of total client assets, but Interactive Brokers commands a premium valuation relative to its revenue because of its exceptionally high margins and consistent account growth. The company’s price-to-earnings ratio of roughly 33.67 signals that investors are willing to pay a meaningful premium for each dollar of earnings, which reflects expectations of continued growth rather than a mature, slow-moving business. It is worth noting that market cap fluctuates daily and can shift by billions on a single earnings report or market-wide sell-off. The figures cited here are snapshots, not permanent valuations. Anyone quoting a single number for what Interactive Brokers is “worth” is simplifying a moving target.
Breaking Down Interactive Brokers’ Revenue and Profit Machine
The real engine behind Interactive Brokers’ valuation is its financial performance, which has been consistently strong. For the full year of 2025, the company generated trailing twelve-month revenue of approximately $9.9 billion. More impressive than the top line is the profitability: Interactive Brokers posted a full-year pre-tax margin of 77 percent, a record for the company. That means for every dollar of revenue, roughly 77 cents flowed through as pre-tax profit. In most industries, margins like that are unheard of. Even within financial services, where margins can be healthy, Interactive Brokers stands apart. The most recent quarter — Q4 2025 — illustrated the trend clearly.
net revenues hit $1.64 billion, a 15.4 percent increase year over year that beat analyst expectations. Adjusted earnings per share came in at $0.65, which was 11 percent above the consensus estimate on Wall Street. Pre-tax income reached $1.30 billion for the quarter, up 25 percent from the same period a year earlier, and the quarterly pre-tax margin of 79 percent set a new record. However, investors should understand that these margins are partly a function of interest rates. Net interest income — the money Interactive Brokers earns on idle cash and margin loans — totaled $966 million in Q4 2025, up 20 percent year over year. If interest rates were to drop significantly, as they did in the years following 2008, that revenue stream would compress. Commission revenue of $582 million, up 22 percent, is more directly tied to trading activity, which can also be cyclical. A prolonged bear market or period of low volatility could dampen both revenue lines simultaneously.
Customer Growth and the Scale Advantage
One of the most telling indicators of Interactive Brokers’ worth is its customer trajectory. By the end of 2025, the company reported 4.40 million customer accounts, a 32 percent increase over the prior year. The firm added over one million net new accounts during 2025, setting an annual record. Total customer equity — the combined value of assets held in those accounts — reached $779.9 billion, up 37 percent year over year. That growth matters because Interactive Brokers operates a highly scalable platform. Unlike a traditional bank that needs to open physical branches to serve new customers, Interactive Brokers can onboard accounts with minimal incremental cost.
Each new account generates potential commission revenue, interest income on idle balances, and fees for premium data and services. The company’s technology-first approach, built over decades, means the cost to serve account number 4.4 million is a fraction of what it cost to serve account number one million. This operating leverage is a major reason the market assigns such a high valuation. A specific example of this scale advantage: Interactive Brokers offers access to 150-plus markets across 34 countries, all through a single unified account. A retail trader in Germany can buy U.S. equities, Japanese futures, and Australian bonds without opening separate brokerage accounts. That global reach attracts sophisticated traders and institutions who consolidate assets on the platform, which in turn drives up customer equity and the revenue it generates.
Is IBKR Stock Fairly Valued at Current Prices?
Whether Interactive Brokers is fairly valued depends on what framework you use. At a P/E ratio of approximately 33.67, the stock is priced well above the broader market average, which typically hovers in the 20-to-25 range for the S&P 500. Bulls argue the premium is justified because Interactive Brokers is growing revenue at double-digit rates, expanding its customer base by 32 percent annually, and doing so with margins that leave almost no room for competitors to undercut on efficiency. Analysts have set an average 12-month price target of $80.67 for IBKR, with a high estimate of $91 and a low of $56. That average target implies roughly 8 percent upside from the February 14, 2026 closing price of $74.79.
The spread between the high and low estimates — $91 versus $56 — reflects genuine disagreement about how sustainable the current growth rate is. The optimistic case assumes continued account growth, stable or rising interest rates, and increasing global trading volumes. The pessimistic case factors in potential rate cuts, regulatory headwinds, or a slowdown in new account acquisition as the easy gains from the post-pandemic trading boom fade. The tradeoff for investors is straightforward: you are paying a growth premium for a company that has consistently delivered, but the stock has already more than doubled from its 52-week low. Buying at $75 is a fundamentally different proposition than buying at $33. The margin of safety is thinner, and any earnings miss or guidance disappointment could trigger a sharp pullback, as is common with high-multiple stocks.
Risks and Limitations to Interactive Brokers’ Valuation
The biggest risk to Interactive Brokers’ current valuation is interest rate sensitivity. With net interest income of $966 million in a single quarter, the company is earning substantial revenue from the elevated rate environment. If central banks pivot to aggressive rate cuts — a scenario that is not impossible if economic conditions deteriorate — that income stream could shrink materially. During the near-zero rate environment of 2020 and 2021, net interest income was a much smaller contributor to the company’s total revenue. Investors buying at current levels should stress-test their thesis against a lower-rate scenario. Regulatory risk is another consideration. As Interactive Brokers expands globally, it faces an increasingly complex web of financial regulations across dozens of jurisdictions.
Changes to margin requirements, reporting rules, or transaction taxes in key markets could increase operating costs or reduce trading volumes. The European Union’s evolving MiFID framework and potential U.S. regulatory changes under shifting political leadership are ongoing uncertainties. There is also the competitive landscape. While Interactive Brokers has long been the platform of choice for active and professional traders, competitors like Charles Schwab, Fidelity, and newer fintech entrants continue to push for market share. The zero-commission revolution, which Interactive Brokers partially adopted with its IBKR Lite tier, has compressed pricing power industrywide. The company’s edge lies in its technology, global market access, and low margin rates, but maintaining that edge requires continuous investment.
What Does Interactive Brokers Pay in Dividends?
Interactive Brokers pays a quarterly cash dividend of $0.08 per share, with the next payment scheduled for March 13, 2026. At a share price of roughly $74.79, that works out to an annual yield of approximately 0.43 percent — modest by any standard. The company has historically prioritized reinvesting profits into its platform and returning value through share price appreciation rather than large dividend payouts.
For income-focused investors, this is not a compelling dividend stock. The payout is almost symbolic. However, it signals that the company generates far more cash than it needs to operate, and management has the flexibility to increase the dividend over time if it chooses. The total equity of $20.5 billion on the balance sheet underscores the financial strength behind even this small payout.
Where Does Interactive Brokers Go From Here?
The forward outlook for Interactive Brokers hinges on whether the company can sustain its account growth trajectory and maintain its industry-leading margins. Adding over one million accounts in a single year is a strong signal, but the question is whether that pace can continue or whether it represents a peak driven by favorable market conditions and heightened retail trading interest. If the company can push toward six or seven million accounts over the next two years while holding margins near 77 percent, the current valuation could prove to be a reasonable entry point.
The broader trend of global market participation is working in Interactive Brokers’ favor. As more individuals worldwide gain access to capital markets — particularly in Asia, Latin America, and the Middle East — a platform that offers unified access to 150-plus markets is well positioned to capture that demand. The company’s technology moat, built over more than four decades, is not easily replicated. Whether the stock is worth $56 or $91 a year from now will depend on execution, interest rates, and the overall market environment, but the underlying business has rarely been stronger than it is today.
Conclusion
Interactive Brokers is worth approximately $127 to $133 billion by market capitalization as of mid-February 2026, backed by nearly $10 billion in annual revenue, record profit margins of 77 percent, and a rapidly expanding base of 4.4 million customer accounts holding close to $780 billion in equity. The Q4 2025 earnings report — with revenues of $1.64 billion, pre-tax income of $1.30 billion, and margins touching 79 percent — demonstrated why the market has rewarded IBKR with a premium valuation and a 53.5 percent gain over the past year.
For anyone evaluating whether to invest, the key considerations are the stock’s sensitivity to interest rate changes, the sustainability of its customer growth, and the relatively high P/E ratio of 33.67 that leaves limited room for disappointment. Analyst targets suggest moderate upside to around $80.67, but the range of estimates from $56 to $91 reflects real uncertainty. The business itself is strong, efficient, and globally diversified — but the price you pay always matters, and IBKR is no longer the bargain it was a year ago.
