The Holding Company Era Is Quietly Ending
HP just pulled a $1B+ media account from Omnicom after 17 years and handed it to Publicis. Sir Martin Sorrell sees no clean exit for the big groups. The consolidation era isn't coming — it's already here.
HP's decision to move its global media account to Publicis — ending a 17-year Omnicom relationship — is not a routine pitch win. It's a signal. Clients this size don't switch holding companies for marginal efficiency gains. They switch when they've decided the incumbent model no longer fits what they're building.
Sorrell's assessment is blunt: there's no easy exit for holding companies from the structural pressures squeezing them. He's right, and the HP move makes it concrete. These groups are caught between AI eating at their labour margins, consultancies eating at their strategic mandates, and clients growing sophisticated enough to question the bundled-service logic that made WPP, Omnicom, and Publicis so dominant for two decades.
The irony is that Publicis is winning here — but winning by being the least broken option, not by being genuinely new. The deeper shift is that *where* media money lives is becoming more contested than ever. The TAG certification collapse, with P&G dropping its mandate and Google and Trade Desk walking away, strips away one of the industry's trusted hygiene signals. Less shared infrastructure, more fragmented trust.
For brand-side marketers and independent agencies, this is the opening. When the big pipes are in flux, smaller and faster operators can move on first principles. The question isn't which holding company wins the next review. It's whether the review model itself survives the decade.
