Omnicom Media Becomes World's Largest Media Management Organisation Following Landmark Integration
Omnicom Media has become the world's largest media management organisation after integrating Omnicom Media Group and IPG Mediabrands, reporting $75.6 billion in global billings. The latest COMvergence rankings highlight its global leadership, major client acquisitions, and India's growing contribution through significant new business wins and expanding market presence.
The integration has significantly reshaped the global media agency landscape, with Omnicom Media now accounting for approximately 31 percent of the total media billings managed by major agency groups. This achievement has propelled the organisation ahead of major competitors, including WPP and Publicis Groupe, establishing it as the industry's largest media management network.
At the agency network level, OMD retained its position as the world's leading media agency network, recording global billings of $26.9 billion. The network secured the top ranking across North America and Europe, the Middle East and Africa, while also leading key markets such as the United States, Canada, Australia and Hong Kong, reflecting its continued strength in major international markets.
Omnicom Media's global leadership has been reinforced by several high-profile account wins and business transitions that became effective during 2025. These include Amazon, Paramount and Volvo, which have expanded the organisation's client portfolio and strengthened its operational capabilities under the unified structure created through the integration.
India has emerged as one of the network's fastest-growing markets during 2026, playing a significant role in Omnicom Media's global expansion. The organisation secured new business worth more than Rs 1,200 crore in billings during the year. Major new mandates include Amazon Music, the Association of Mutual Funds in India (AMFI) and Netflix India, further strengthening its portfolio of leading advertisers.
The Indian market has also witnessed sustained business development, with earlier client additions such as Tata Motors, Marico and OpenAI contributing to the network's expanding scale and diversification across multiple industry sectors.
Commenting on the achievement, Florian Adamski, Chief Executive Officer of Omnicom Media, said the rankings demonstrate the strategic advantages created through integration. He stated, "The significance of these rankings is not simply that we are the largest. It is what that scale enables. When scale is connected through common capabilities, shared intelligence and world-class talent, it becomes an advantage for clients."
Highlighting the importance of the Indian market, Kartik Sharma, Chief Executive Officer of Omnicom Media India, said business growth in the country is increasingly being driven by innovation rather than scale alone. He stated, "In India, growth is no longer driven by size alone, but by the ability to turn data, culture and commerce into business outcomes. The strength of Omnicom Media lies in bringing together global scale and local intelligence."
The latest COMvergence rankings underscore the transformative impact of the integration between Omnicom Media Group and IPG Mediabrands.
