Omnicom's Best Quarter Since the Interpublic Merger
Updated: 1 day ago
Omnicom has posted its strongest quarter since swallowing Interpublic, with organic revenue growth of roughly 3.9% driven mainly by media and the US market — while traditional creative shrank, a split that tells you exactly where ad-industry money is flowing.
The merger is paying off — unevenly
Omnicom's third-quarter results are the clearest sign yet that its landmark acquisition of Interpublic is bedding in. The group reported organic revenue growth of around 3.9%, its best performance since the deal closed, with momentum concentrated in media and in the United States. It is a confident number in a jittery market.
But the headline hides a telling divide. The growth came from media buying and data-driven services, while traditional creative advertising contracted. The combined giant is getting bigger where the money is — and quietly smaller where it isn't.
Why media is winning and creative is shrinking
Media is where scale, data and technology compound. A bigger agency buys more efficiently, bargains harder and sits on richer audience data — advantages that grow with size. Creative, by contrast, does not scale the same way: a brilliant idea from ten people is worth as much as one from a thousand, and clients increasingly produce routine creative in-house.
That is why the mega-mergers of the holding-company world are really about media and data muscle, not creative firepower. Omnicom's results are the proof in the numbers.
What it means for brands and smaller agencies
For advertisers, consolidation means fewer, more powerful media partners — greater efficiency, but also less leverage and more dependence. If your media sits with a giant, negotiate transparency and portability into the contract while you still can.
For independent agencies, the opportunity is the opposite end of the barbell: the distinctive creative and strategic thinking the giants are de-prioritising. As holding companies industrialise media, the space for sharp, senior, ideas-led shops actually widens.
Quick FAQ
How did Omnicom perform in Q3 2026?
It reported its strongest quarter since the Interpublic merger closed, with organic revenue growth of roughly 3.9%, led by media and the US market while creative advertising contracted.
Why is media growing faster than creative?
Media buying benefits from scale, data and technology that compound with size, while creative does not scale the same way and is increasingly produced in-house by clients.
Omnicom's numbers tell the real story of the holding-company era: the growth is in media and data, not creative. These mega-mergers were never about better ideas — they were about buying power. For brands, that means fewer, stronger partners; for independents, it's an opening to own the creative the giants keep shrinking. — Daniel Nikolla, Founder of Merx Marketing
