Omnicom Media Named World's Largest Global Media Management Network
Omnicom Media became the world's largest global media management network with 30.1% market share and $107.3 billion in billings according to a RECMA report.
The Research Company Evaluating the Media Industry (RECMA) named Omnicom Media the world's largest global media management network in its 2025 Overall Activity Volume report. The network recorded $107.3 billion in billings, capturing 30.1% of the global media agency market and leading activity volume across North America, EMEA, and LATAM.
This leadership position follows the November 2025 integration of Omnicom and IPG's media operations. Within the company's portfolio, OMD remains the largest individual media network with $35.1 billion in activity volume and a 9.9% global market share. The report also noted growth for PHD and Hearts & Science, with the latter scheduled to merge with Mediahub next month to form a new brand.
Omnicom Media has secured more than $3 billion in year-to-date billings from clients including Adidas, Delta Air Lines, Dyson, IBM, Subway, and Uber. CEO Florian Adamski attributed the company's success to investments in talent, technology, data, and commerce capabilities designed to translate scale into growth for leading brands.
