Global advertising giants Omnicom Group and Interpublic Group (IPG) have officially merged, forming the world’s largest advertising and marketing company. The deal, valued at around $13.25 billion in an all-stock transaction, gives former Omnicom shareholders 60.6% and IPG shareholders 39.4% of the combined company. IPG shareholders received 0.344 Omnicom shares for each IPG share.
The merger brings together some of the most prominent creative and media agencies worldwide, including McCann, FCB, MullenLowe, and IPG Mediabrands, under one roof. With a combined annual revenue exceeding $25 billion, the new entity will dominate global advertising and become the second-largest network in India, after WPP plc.
Regulatory approvals were completed recently, with the European Commission giving unconditional clearance, allowing the merger to finalize. Industry analysts note that while the merger strengthens the company’s global scale and resources, it may also lead to job consolidations and operational changes as overlapping agencies restructure.
The merger highlights how major advertising firms are seeking scale to compete amid declining traditional ad revenues and the rise of digital and AI-powered marketing solutions. For Indian advertisers, this consolidation could influence media buying, campaign strategies, and pricing, as fewer large networks control a bigger share of the market.
