Interactive Brokers delivered another quarter of rapid growth, with accounts, equity, and trading activity all surging while pretax margins stayed above 70%. The stock earns a Buy, but valuation is no bargain after a strong run.
Interactive Brokers Group (IBKR) combines strong growth, unusually high operating efficiency, and a conservative balance sheet. The company reported $1.90B of net revenue and $0.69 of diluted EPS in 2Q 2026, up from $1.48B and $0.51 in the year-earlier quarter. Customer accounts grew 34% to 5.19 million, customer equity increased 40% to $930.3B, and daily average revenue trades rose 36% to 4.8 million.
The investment case rests on a technology-led brokerage model that converts scale into earnings. IBKR produced a 77% pretax margin in 2Q 2026, its seventh consecutive quarter above 70%. Commission revenue rose 30% to $673M, while net interest income increased 23% to $1.06B. Its global platform, low-cost structure, margin lending, securities lending, and expanding product range give the company several ways to monetize each client relationship.
At the latest quoted price of $92.95, IBKR trades at 36.9 times trailing earnings and 28.6 times forward earnings. That is not a bargain multiple for a cyclical brokerage, but revenue growth of 26.3%, earnings growth of 35.3%, a 10.1% free-cash-flow yield, and an analyst target of $105.74 provide support for a moderate-risk Buy rating. The principal risks are dependence on market activity and interest rates, intense price competition, regulation, and technology execution.
Founded in 1977 and headquartered in Greenwich, Connecticut, Interactive Brokers Group operates an automated electronic brokerage serving the United States and international markets. The company listed on Nasdaq in 2007 and employed 3,265 people as of June 30, 2026. Milan Galik serves as president and chief executive officer, while founder Thomas Peterffy remains chairman.
IBKR provides execution, clearing, settlement, custody, prime brokerage, securities lending, and margin lending. Its product set covers stocks, options, futures, foreign exchange, bonds, precious metals, funds, cryptocurrencies, and event contracts. The platform reaches more than 170 market centers in 40 countries and supports 29 currencies, giving the company a broader international footprint than most U.S. retail brokers.
The customer base spans individual investors, hedge funds, proprietary trading groups, financial advisors, introducing brokers, exchange-traded funds, and mutual funds. This mix matters because IBKR is not dependent on a single retail product. Active traders generate commissions and margin interest, institutions add custody and financing balances, and introducing brokers provide a distribution channel without requiring IBKR to build a branch network.
IBKR reports its business primarily through revenue lines rather than conventional operating segments. The 2Q 2026 mix shows two dominant engines. Commission revenue reached $673M, up 30% year over year, while net interest income reached $1.06B, up 23%. Together, these lines represented the core of the quarter's $1.90B net revenue.
Commission revenue benefits from customer activity across stocks, options, and futures. Options contract volume increased 17% year over year, futures volume rose 2%, and stock share volume increased 14%. The $2.64 commission per cleared commissionable order was slightly lower than the prior year, showing that volume, rather than higher pricing, drove the result.
Net interest income monetizes customer margin loans, segregated cash, and other interest-sensitive balances. Customer margin loans reached $108.5B in 2Q 2026, up 67% year over year, while customer credits rose 27% to $182.4B. Margin loan interest increased 39% despite a 70-basis-point decline in the average U.S. Fed funds rate, because higher balances offset lower rates.
Other fees and services generated $87M, up 40%, helped by options-related order-flow payments and risk exposure fees. Execution, clearing, and distribution costs reached $142M, up 22%, partly because the SEC Section 31 fee rate resumed in April 2026. These costs are largely passed through, which limits their effect on profit.

The flagship product is IBKR's unified brokerage account and trading infrastructure. Trader Workstation serves advanced users, IBKR Desktop targets a streamlined desktop experience, IBKR Mobile supports trading on handheld devices, Client Portal handles account administration, and GlobalTrader focuses on simplified global investing. APIs allow clients to connect their own software, spreadsheets, and automated workflows.
The platform's strongest feature is breadth in a single account. A client can trade stocks, options, futures, currencies, bonds, funds, crypto, and event contracts across more than 170 market centers. That breadth reduces the need to maintain several specialist accounts and gives IBKR more opportunities to capture margin balances, cash, securities lending revenue, and transaction activity.
Recent additions expand the product's reach. IBKR opened access to the Korea Exchange and Nextrade, began offering cryptocurrencies across Europe, offered the SpaceX IPO to eligible U.K. and European retail clients, and launched a unified prediction-markets platform connecting ForecastEx, CME, and Kalshi. Overnight trading volume nearly tripled year over year to 10.9 million trades in 2Q 2026.
IBKR's competitive advantage comes from the combination of automation, market access, pricing, and risk controls. The company has spent decades building electronic execution and custody systems, allowing it to operate with 3,265 employees while producing a 77% pretax margin. That cost structure supports competitive commissions, financing rates, and cash yields.
The company also received preliminary conditional approval from the OCC for a national trust bank charter. Management said the necessary work was planned for completion by year-end, with the charter intended to support direct custody for mutual fund and ETF customers. That initiative expands the addressable custody opportunity beyond the existing active-trader base.
AI is the newest layer of that strategy. IBKR Connector links client accounts with Anthropic, OpenAI, and xAI tools for portfolio analysis, research, and trade preparation. The company uses a human-in-the-loop process in which the client approves an AI-generated instruction before it becomes an executable order. That structure adds convenience while preserving an explicit client control point.
A brokerage has no conventional manufacturing supply chain. Its operating infrastructure consists of trading connectivity, clearing relationships, custody systems, market data, compliance controls, cybersecurity, and client service. IBKR's 2Q 2026 results show that this digital infrastructure is scaling: total assets rose 36% year over year to $247B, customer accounts reached 5.19 million, and DARTs reached 4.8 million per day.
The introducing-broker channel is an important operating lever. Management described the pipeline as healthy and said the company had recorded a double-digit number of integrations going online for roughly the fourth or fifth consecutive quarter. New partners included existing firms expanding from a single product into broader stock, derivatives, crypto, or international offerings.
IBKR's balance-sheet operations also emphasize short duration and maturity matching. The average duration of the investment portfolio remained below 30 days in 2Q 2026. Management said the company extended duration modestly after the U.S. dollar yield curve turned positive in the short and medium term while retaining a tight match between assets and liabilities.
Scaling efficiency remains visible in expense data. Compensation was $182M in the quarter, equal to 10% of adjusted net revenue, down from 11% a year earlier. General and administrative expense was $68M, with advertising expansion contributing to the increase. The model adds clients and products without requiring a proportional increase in staffing.
The global securities brokerage market was estimated at $1.91T in 2026 and is projected to reach $2.85T by 2031, an 8.3% compound annual growth rate. Retail investors are the fastest-growing client type at a projected 9.7% rate, while robo-advisory and automated advisory are projected to grow at 12.8%.
Those trends fit IBKR's structure. The company sells digital access rather than branch-based advice, serves individual and institutional clients, and uses automation in onboarding, compliance, surveillance, and service. Asia-Pacific is projected to be the fastest-growing regional brokerage market at 11.3%, giving IBKR's Korean launch and broader international reach strategic relevance.
The market also carries structural pressure. Commission revenue represented 37.7% of brokerage-market revenue in 2025, while fee revenue was the faster-growing model. IBKR addresses fee compression through scale, margin lending, cash balances, securities lending, and additional products such as prediction markets and crypto. The result is a revenue model with more levers than a simple stock-trading commission business.

IBKR's customer base is unusually broad in sophistication and geography. It serves self-directed individuals, hedge funds, proprietary trading groups, financial advisors, introducing brokers, ETFs, and mutual funds. The platform's strongest natural fit is the active or professional client who values global access, derivatives, margin tools, low pricing, and direct control over execution.
The 2Q 2026 customer metrics show rising wallet depth. Client equity reached $930.3B, customer uninvested cash reached a record $182.4B, and customer margin loans reached $108.5B. These balances create revenue opportunities even when a client does not trade heavily, while active trading adds commission and securities lending activity.
Client growth also remained broad. Management said account growth was occurring across all regions and account types, including financial advisors, introducing brokers, and direct accounts. A regulatory clampdown on Tiger and Futu in mainland China produced an increase in transfers to IBKR from those platforms, although management described some of the activity as existing IBKR clients shifting assets.
IBKR competes with Charles Schwab (SCHW), Fidelity, Robinhood (HOOD), E*TRADE within Morgan Stanley (MS), Saxo Bank, XTB, prime brokers, and large financial institutions. Competition centers on commissions, financing rates, execution quality, product breadth, account experience, market access, and client cash yields.
Charles Schwab and Fidelity have stronger positions in mass-market U.S. wealth management, retirement accounts, and advisory relationships. Robinhood emphasizes a simplified mobile experience and retail engagement. IBKR differentiates through global market access, professional tools, multi-asset trading, margin financing, and direct APIs.
IBKR's advantage is clearest for clients who need more than basic U.S. equity trading. Its access to 170-plus market centers, 29 currencies, and multiple derivatives markets is difficult for smaller platforms to reproduce. Its automated structure also supports lower operating costs and a 77% pretax margin.
The counterargument is that technology advantages decay when competitors invest aggressively. IBKR's 10-K identifies competition from electronic brokers, prime brokers, financial institutions, fintech companies, and alternative trading venues. AI-driven interfaces, tokenized securities, on-chain settlement, and exchange disintermediation create new competitive vectors. IBKR's response is visible in Connector, APIs, 24-hour trading, crypto, prediction markets, and continued automation.
IBKR benefits when investors trade actively and maintain balances on the platform. In 2Q 2026, the S&P 500 rose nearly 15%, while management described technology stocks and semiconductor names as popular among clients. That market backdrop supported higher commissions, derivatives activity, margin borrowing, and client engagement.
Interest rates remain a major earnings variable. Management estimated that a 25-basis-point increase in the benchmark Fed funds rate would add $81M to annual net interest income from the June 30 balance base. A comparable move across relevant non-U.S. benchmarks would change annual net interest income by $38M. Higher client balances partly offset the effect of lower rates, as shown by the 23% increase in 2Q net interest income despite the lower average U.S. Fed funds rate.
Regulation creates both costs and opportunities. The SEC Section 31 fee-rate increase on April 4, 2026 lifted execution, clearing, and distribution fees by $19M in the quarter. Meanwhile, preliminary conditional approval for a national trust bank charter could broaden custody capabilities for mutual fund and ETF customers.
International exposure adds geopolitical sensitivity. About 30% of 2025 net revenue came from operating subsidiaries outside the United States. The company's compliance with mainland Chinese account rules helped it benefit from transfers away from Tiger and Futu, while the Korean market launch increased access to semiconductor-related trading. Currency, local regulation, capital controls, and political events remain material variables for a global broker.
Customer equity climbed 40% to $930.3B while the company maintained a conservative balance sheet and kept leverage tied to client activity rather than heavy borrowing.

Get Full Access →Interactive Brokers Group has built one of the more efficient platforms in financial services. The evidence is concrete: $1.90B of 2Q 2026 revenue, 34% account growth, 40% client-equity growth, a 77% pretax margin, $22.3B of firm equity, and almost no corporate debt. Its global access and product expansion add growth options beyond traditional stock commissions.
The shares are not priced as a distressed financial stock, and the 36.9 times trailing earnings multiple demands continued execution. Still, the $92.95 price remains below the $106 fair value estimate, while the analyst consensus target is $105.74. For a medium-term, moderate-risk investor, that combination supports a Buy rating, with the clearest opportunity appearing on weakness toward the $90 Buy level.
