FRANCE – 22 MAY 2026 – According to COMvergence’s Q1 2026 Global New Business Barometer (NBB), WPP Media led both the Total and Net New Business global rankings, generating $1.5B in new client billings. Key wins included Jaguar Land Rover and Estée Lauder globally, and SC Johnson in North America. The newly formed Omnicom Media Group — now consolidating results from six agency networks: Initiative, Hearts & Science, Mediahub, OMD, PHD, and UM — followed in second place, combining $1B in new client wins with $1B in retentions, including Delta Airlines and Dyson. Publicis Media ranked third, with a comparatively modest new business performance relative to the other two groups.

Olivier Gauthier, Founder and CEO of COMvergence, commented:
“Of the $7 billion in total reviewed media spend, 25% — representing $1.8 billion — was awarded to bespoke solutions operated directly by one of the Big 3 holding groups: WPP Media, Omnicom Media, and Publicis Media. WPP Media secured $1.2 billion, followed by Omnicom Media with $520 million and Publicis Media with $80 million. Our Global Q1 2026 New Business Barometer marks the first time that group-dedicated teams have represented such a significant share of total reviewed spend, reflecting the growing consolidation of media business within bespoke, centralized group solutions.”
At agency network level, Wavemaker ranked #1 globally with a Total New Business Value of $382M, driven primarily by the retentions of Huawei in China and Reckitt in India. EssenceMediacom ranks 2nd, boosted by the retention of the Estée Lauder account in China, while Hearts & Science takes 3rd position on the back of the retention of Cox Automotive in the US and the win of Xiaomi in China. In terms of net new business (excluding retentions), Local Planet — a consortium of independent media agencies present in 50+ countries — leads the ranking with $146M in incremental billings won, driven primarily by the strong performance of German-based agency Pilot.
