Omnicom Media has emerged as the world's largest media management network in terms of billings following the integration of Omnicom Media Group and IPG Mediabrands, according to COMvergence Final 2025 Global & Regional Billings Rankings.

The combined entity reported global billings of $75.6 billion at the end of 2025, accounting for 31% of the media billings managed by the world's leading agency groups. According to the report, Omnicom Media outpaced WPP by $11.8 billion and Publicis Groupe by $13.2 billion.

The rankings mark the first official assessment of the merged media business following Omnicom's acquisition of IPG, which closed in November 2025.

Regionally, Omnicom Media ranked as the largest media management network in North America, with billings of $35.9 billion, including $33.1 billion in the US. It also led the Latin American market with billings of $2.3 billion.

The company attributed its leadership position to the integration of Omnicom Media Group and IPG Mediabrands, along with major account wins that became effective in 2025, including Amazon, Paramount and Volvo. In India, the company highlighted Tata Motors, Marico and OpenAI among its notable client additions.

"The significance of these rankings isn't simply that we're the largest—it's what that scale enables," said Florian Adamski, CEO of Omnicom Media, was reported as saying. 

Kartik Sharma, CEO of Omnicom Media India, told media networks that the company remains focused on combining global scale with local expertise to help marketers accelerate growth.

According to COMvergence dashboards, Omnicom Media secured $2.5 billion in new business globally during the first half of 2026, including mandates from Delta, Dyson and IBM. In India, the company said it has won business worth more than Rs 1200 crore this year, including Amazon Music, AMFI and Netflix.
