Direct Answer
Citigroup reports revenue across 5 business segments in its fiscal 2025 Form 10-K. Markets is the largest, with $22.0 billion of revenue (26% of the total), followed by Services at $21.3 billion (25%).
How Does Citigroup Make Money?
No single line supplies a majority of revenue: the largest, Markets, is 26%, which spreads Citigroup's exposure across several demand drivers. Between fiscal 2024 and 2025, Banking grew fastest (+32.5%) and US Personal Banking slowest (+4.6%), so the revenue mix tilts toward Banking while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Markets | $22.0 billion | $19.8 billion | 25.8% | 10.8% |
| Services | $21.3 billion | $19.6 billion | 24.9% | 8.3% |
| US Personal Banking | $21.0 billion | $20.1 billion | 24.6% | 4.6% |
| Wealth | $8.6 billion | $7.5 billion | 10.0% | 14.4% |
| Banking | $8.2 billion | $6.2 billion | 9.6% | 32.5% |

What the Segment Figures Do Not Show
The rows above add up to 95% of Citigroup'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 Citigroup reported in the segment note and revenue disclosures of its Form 10-K filed February 20, 2026 (accession 0000831001-26-000011), 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.
