We initiate coverage on Interactive Brokers with a Hold rating and an $84.00 price target. At 26.6 times 2027 estimated earnings of $3.11, the stock fairly balances 35% account growth against moderating trading velocity and interest rate sensitivity.
Key points
- $105.2 billion in client margin loans, up 36% year over year, anchors record interest income.
- 5.58 million customer accounts expanded 35%, offsetting softening per-account trading velocity.
- 78% pretax margin demonstrates exceptional operating efficiency from an automated infrastructure.
The call
The current share price of $82.67 requires Interactive Brokers to sustain 22% annual earnings growth through 2027 while holding its valuation multiple near 31 times trailing earnings. That expectation prices in uninterrupted margin balance expansion alongside resilient global policy rates. The market effectively assumes that retail and institutional client leverage can compound through any macroeconomic backdrop without activity compression.

We believe the stock is fairly valued today as steady account growth balances out moderating trading velocity. While margin borrowing remains robust, customer trading activity per account has softened 14% year over year. Higher asset balances will offset central bank benchmark cuts, driving 2027 diluted earnings to $3.11 per share. At 27 times forward earnings, risk and reward appear evenly balanced.
Valuation
Our 12-month price target of $84.00 is derived from a 27.0 times price-to-earnings multiple applied to our 2027 estimated diluted earnings of $3.11 per share.
| Valuation Step | Estimate |
|---|
| FY 2026 Net Revenues | $7.40 billion |
| FY 2027 Net Revenues | $8.45 billion |
| FY 2027 Pretax Margin | 79.6% |
| FY 2027 Net Income to Common | $1.42 billion |
| FY 2027 Diluted Shares | 456.0 million |
| FY 2027 Diluted EPS | $3.11 |
| Target Forward Multiple | 27.0 times |
| 12-Month Price Target | $84.00 |
A 27 times multiple fairly reflects Interactive Brokers' 78% pretax margin and automated platform advantages over legacy retail brokers, but leaves limited multiple expansion given its already full premium. The resulting 1.6% upside supports a Hold rating.
Risks
- Benchmark interest rate cuts exceeding 100 basis points across major currencies, monitored via the effective federal funds rate and quarterly net interest margin schedules.
- Accelerated compression in retail trading engagement, monitored through monthly daily average revenue trades per account.
- Severe equity market downturns driving sharp margin loan liquidations, monitored via monthly margin balance releases.
What would change my mind
Re-accelerating trading velocity per account alongside sustained customer margin loan growth above 30% that pushes 2027 earnings per share above $3.40 would make us buyers.
