Publicis shows strong growth as AI takes center stage, but advertisers should monitor which holdcos prove AI-driven gains across planning, activation, and outcomes.

Ad agencies face AI disruption, consolidation, in-housing, and economic pressure. Legacy models are cracking as clients automate more work, forcing agencies to rethink their business strategies—or risk falling behind.

2025 saw mergers, layoffs, and AI overhauls as the agency model fractured and reformed.

WPP, once the top advertising group globally, will be retired from the FTSE 100 after almost 30 years as its market value has fallen dramatically in recent years. Removal from the FTSE 100 and a plummeting market value indicates that WPP’s struggles are deep-rooted and unlikely to vanish in the near future. For advertisers, the current imperative is to rethink partnerships, explore alternatives, and increase diligence.

Omnicom officially owns IPG after completing its long-discussed acquisition last week—and the new company is already implementing a massive wave of changes. Advertisers should prepare for an agency landscape where AI-driven capabilities become the norm and where consolidated services become a competitive differentiator.

Holding company Publicis Groupe reported a strong Q3 2025, growing organic net revenues 5.7% YoY, above analyst growth expectations of 5.19%. The company now expects 2025 revenues to grow between 5% to 5.5%, up from its previous forecast of 4% to 5%. Publicis’ heavy AI push and performance-driven strategy means it is well-positioned to continue growing while rival agencies struggle to remain competitive amid economic turbulence.

The news: WPP has taken another hit in earnings, underscoring the current unstable market defined by economic uncertainty.Profits dropped 71% pre-tax in the first half of the company’s financial year, falling to £98 million ($125.2 million), while operating profit fell nearly half (47.8%), reaching £221 million ($282.3 million). Our take: WPP’s profit plunge serves as a wake-up call for agencies to accelerate transformation and prove value beyond media buying. In an AI-dominated landscape, advertisers are demanding more for less.

The news: Publicis Groupe has won PayPal’s global media business, building on the holding company’s winning streak and proving to rivals that its momentum in securing major accounts shows no signs of slowing. WPP Media previously handled PayPal’s media account but resigned the account in April, citing the need to “pursue other opportunities,” per Ad Age. Our take: Publicis’ win of PayPal’s global media business underscores a growing advertiser shift toward integrated partnerships, where creative, media, and retail strategies merge to unlock greater performance and monetization potential.

The news: WPP’s CMO and CEO of its Coca-Cola agency, Laurent Ezekiel, will depart the company to join Publicis, adding to a string of high-profile losses for the struggling holding company. Our take: With Ezekiel’s and Read’s departures, WPP is at an inflection point as it struggles to reinvent itself and keep pace with competitors. The company faces mounting pressure as other holding companies develop stronger digital and data-driven capabilities. WPP’s future depends on how well its new CEO can close gaps in modernization, build its AI investments, and enact significant operational changes.
