Direct Answer
Interactive Brokers reports revenue across 2 geographic regions in its fiscal 2025 Form 10-K. United States is the largest, with $4.3 billion of revenue (70% of the total), followed by Outside the United States at $1.9 billion (30%). 70% of revenue came from the United States.
How Does Interactive Brokers Make Money?
United States supplies 70% of revenue, so Interactive Brokers's results move mostly with that one region; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, United States grew fastest (+20.5%) and Outside the United States slowest (+17.9%), so the revenue mix tilts toward United States while that gap lasts.
| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| United States | $4.3 billion | $3.6 billion | 69.7% | 20.5% |
| Outside the United States | $1.9 billion | $1.6 billion | 30.3% | 17.9% |
What the Segment Figures Do Not Show
The rows above add up to 100% of Interactive Brokers's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Interactive Brokers reported in the segment note and revenue disclosures of its Form 10-K filed February 27, 2026 (accession 0001381197-26-000062), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
