Segment Reporting [Abstract]  
Segment Reporting Segment Reporting
Our branded agency networks operate in the advertising, marketing and corporate communications services industry, and are organized into agency networks, virtual client networks, regional reporting units and operating groups or connected capabilities. Our networks, virtual client networks and agencies increasingly share clients and provide clients with integrated services. The main economic components of each agency are employee compensation and related costs, direct service costs and occupancy and other costs which include rent and occupancy costs, technology costs and overhead expenses. Therefore, given these similarities, we aggregate our four operating segments, which are our global agency networks, into one reporting segment. The Chief Operating Decision Maker, or CODM, reviews segment operating income for each network and allocates resources accordingly. Beginning in December of 2025, we integrated the newly acquired IPG businesses into our existing four networks. The CODM includes Omnicom’s chief executive officer, chief financial officer and chief operating officer.
Segment operating results include allocations of costs, including information technology, and other shared services costs, that are allocated using metrics designed to correlate the allocation with consumption.

We reconcile segment operating income to income before income taxes and income (loss) from equity method investments as income tax expense is reviewed at the consolidated level and the segment managers are not held accountable for performance of net income.
The agency networks' regional reporting units comprise three principal regions: the Americas, EMEA and Asia-Pacific. The regional reporting units monitor the performance and are responsible for the agencies in their region. Agencies within the regional reporting units serve similar clients in similar industries and, in many cases, the same clients and have similar economic characteristics.
