Unitedhealth brought in $237.76B from its three segments in fiscal 2025, the year ended December 31, 2025. That is less than the $400.87B it reports by major customers, so these segments do not cover all of its revenue. Optum Rx was the largest at $154.73B (65.1%), ahead of Optum Health at $63.62B (26.8%) and Optum Insight at $19.42B (8.2%).
Compared with fiscal 2024, Optum Rx grew fastest, up 189.7% to $154.73B, while Optum Health fell the most, down 39.6% to $63.62B. Some of that change comes from Unitedhealth regrouping its segments.
Unitedhealth stopped reporting Optum as a separate segment after fiscal 2024, when it brought in $99.28B.
Unaffiliated Customers was Unitedhealth’s largest revenue line in fiscal 2025, bringing in $342.73B of $400.87B (85%).
