Interactive Brokers Group (IBKR) Financials

Interactive Brokers Group (NASDAQ: IBKR) is showing strong operating and balance-sheet growth, although much of its cash-flow volatility reflects changes in customer-related assets and liabilities rather than traditional corporate free cash flow. The latest quarter, Q2 2026, continued the company’s multi-year expansion in revenue, customer receivables, assets and equity.

• Revenue growth remains robust. Q2 2026 revenue increased to $1.896 billion from $1.480 billion in Q2 2025, a 28.1% year-over-year increase. Compared with Q3 2022, revenue has more than doubled, rising approximately 140%.
• Net interest income is accelerating. Q2 2026 net interest income rose 16.9% from the prior quarter and 22.9% year over year to $1.057 billion. This remains IBKR’s largest revenue source, benefiting from the company’s expanding customer cash and securities balances.
• Commission and trust-fee revenue is trending higher. Trust fees by commissions reached $673 million in Q2 2026, up from $613 million in Q1 2026 and $516 million in Q2 2025. This provides greater revenue diversification beyond interest income.
• Profitability continues to improve on a consolidated basis. Consolidated net income increased to $1.338 billion in Q2 2026 from $1.171 billion in Q1 and $1.006 billion in Q2 2025. Net income attributable to common shareholders rose 16.9% sequentially and 39.3% year over year to $312 million.
• Per-share earnings are moving higher on a comparable basis. Basic EPS increased to $0.70 in Q2 2026 from $0.60 in Q1 and $0.51 in Q2 2025. The share-count figures changed substantially between 2023 and 2024, so longer-term EPS comparisons should be interpreted cautiously, but the post-2024 trend is favorable.
• Operating cash generation is strong. Cash flow from operating activities reached $6.216 billion in Q2 2026, up from $3.611 billion in Q1 2026. Cash and due from banks also increased to $7.711 billion from $5.085 billion in Q1.
• IBKR’s customer and asset base continues to expand. Total assets reached $247.309 billion in Q2 2026, up from $218.749 billion in Q1 and $181.475 billion in Q2 2025. Customer and other receivables rose to $108.939 billion, compared with $86.544 billion one year earlier and $43.602 billion in Q3 2023.
• Common equity and retained earnings are building. Total common equity increased to $5.904 billion in Q2 2026 from $5.585 billion in Q1 and $4.825 billion in Q2 2025. Retained earnings have risen steadily across the reported periods, indicating continued earnings accumulation after dividends.
• Cash-flow results are highly sensitive to customer activity. Q2 2026 included a $15.419 billion non-cash adjustment and a $10.567 billion use of operating capital. Similar large swings appeared in earlier quarters, meaning operating cash flow can fluctuate sharply as customer balances and securities move.
• Leverage and the share of assets funded by liabilities are increasing. Total liabilities reached $225.059 billion in Q2 2026, or roughly 91% of total assets, compared with $197.489 billion in Q1. Short-term debt increased to $177.611 billion from $163.635 billion, while long-term debt rose to $45.410 billion from $32.016 billion in Q1 2026. This is typical of a broker-dealer balance sheet but remains an important risk during periods of market stress or customer withdrawals.

IBKR’s recent results point to a business benefiting from customer growth, higher interest income and rising trading-related activity. Q2 2026 total revenue increased 13.6% sequentially, while net income attributable to common shareholders rose 16.9%. However, non-interest expenses also increased to $440 million from $381 million in Q1, and the company’s pretax margin edged down slightly to approximately 76.8% from 77.2%.

Investors should also account for Interactive Brokers Group’s ownership structure. In Q2 2026, $1.026 billion of consolidated net income was attributable to noncontrolling interests, leaving $312 million attributable to common shareholders. This means consolidated earnings growth does not translate dollar-for-dollar into earnings available to IBKR common stockholders.

Overall, the statements show a financially expanding and highly profitable brokerage platform, supported by strong customer-related growth and substantial operating cash generation. The main issues to monitor are rising short- and long-term debt, volatile customer-driven cash flows, operating-expense growth and the large portion of earnings allocated to noncontrolling interests.
