The Omnicom-IPG merger represents the most extreme example of consolidation pressure. The $13.5 billion deal creates the world’s largest advertising holding company.
Before (December 2024): 6 major holding companies — WPP, Omnicom, Publicis, IPG, Dentsu, Havas
After (December 2025):
- Omnicom + IPG: $13.5B deal, $750M synergies
- ~4,000 jobs cut
- Only 3 creative networks remain: McCann, BBDO, TBWA
Brands Retired: FCB, DDB, MullenLowe, Y&R, J. Walter Thompson, Wunderman — legendary names gone forever.
As Andrew Essex, former CEO of Droga5, observed:
“This is a significant unprecedented contraction in the size of the entity formerly known as Madison Avenue. This is like California falling into the ocean.“
The New Omnicom Structure: 3 creative networks + 9 connected capabilities + unified technology platform (Omni + OmniAI + ArtBot + Flywheel Commerce Cloud)
