The Competition Commission of India (CCI) has approved the $30 billion merger between U.S.-based advertising giants Omnicom Group Inc. and Interpublic Group of Companies, Inc. (IPG). The deal will create the world’s largest advertising network by revenue, with projected global media billings of around $65 billion.
Shareholders approved the merger in March, and the transaction is expected to close in the second half of 2025. As per the agreement, Omnicom’s wholly owned subsidiary, EXT Subsidiary Inc. (Omnicom Merger Sub), will merge into IPG. Following the merger, IPG will become a wholly owned subsidiary of Omnicom, while the merger sub will cease to exist.
Omnicom, headquartered in New York, operates a global network of marketing and communications agencies offering services such as brand advertising, media buying, CRM, and public relations. IPG, based in Delaware, provides media planning and buying, data-driven marketing, integrated advertising, and experiential solutions.
Originally announced in late 2024, the merger is positioned as a strategic move to strengthen capabilities, unify global talent, and offer a broader suite of marketing services. The combined entity aims to become a dominant force in navigating the evolving global media and advertising landscape.
