What's Driving IBKR's Business? Latest 10-Q Breakdown
✓ 31/31 datapoints verifiedAI-extracted from Interactive Brokers Group, Inc.'s 10-Q filed 2026-05-07 — Q1 2026 (quarter ended March 31, 2026). Every figure is machine-verified against the filing text on SEC EDGAR.
Interactive Brokers reported Q1 2026 net revenues of $1,669M (+17% YoY) and net income of $1,171M (+22% YoY), driven by 19% growth in commissions to $613M on higher customer trading volumes across stocks, futures, and options.
Biggest Revenue Drivers
Total revenue: $1,669M+17% YoY
Higher average customer margin loans and customer credit balances, partially offset by lower benchmark interest rates.
Higher customer trading volumes in stocks (25%), futures (20%), and options (16%).
Increases in FDIC sweep fees, market data fees, and payments for order flow, offset by lower risk exposure fees.
Gains from principal transactions and currency diversification strategy, partially offset by investment mark-to-market losses.
Largest Expense Items
Higher interest paid on customer credit balances and securities lending activities.
Staffing increases and inflation, with average employees rising 6% to 3,207.
Lower regulatory fees as SEC Section 31 transaction fee reduced to zero; greater capture of liquidity rebates.
Higher advertising expenses primarily.
Margins: Pretax profit margin expanded to 77% in Q1 2026 from 74% in the prior-year quarter, and adjusted pretax margin improved to 77% from 73%, driven by strong revenue growth (+17% YoY) and controlled expense growth (+2% YoY) with execution fees declining due to the SEC fee elimination.
Watch Items from the Filing
- Customer margin loans of $86.5B represent concentrated credit exposure; rapid market declines could trigger forced liquidations and losses if collateral becomes insufficient, though daily margining systems provide mitigation.
- Net interest margin compressed from 2.10% in Q1 2025 to 1.88% in Q1 2026 due to lower interest rates; further rate cuts would reduce net interest income, though lower rates also reduce interest expense.
- Class action settlement of up to $5M in debt forgiveness reached January 2026 relating to liquidation pricing practices; fairness hearing scheduled June 17, 2026.
- Retail trading participation elevated but subject to market sentiment fluctuations; trading volumes (customer DARTs +24% YoY) remain dependent on volatility and investor engagement which are unpredictable.
