The Trade Desk scrutiny is opening doors, as rivals court buyers after audits—but agency AI ecosystems and walled gardens pose the real threat to DSPs.

Omnicom’s AI emphasis is raising talent questions, as sparse mentions of people highlight layoffs and a broader industry tilt toward automation and cost efficiency.

Publicis dominated 2025 new business with $10 billion in wins and slim losses, widening the gap as competitors like WPP stumbled.

Publicis buys measurement company AdgeAI, arming Publicis with real-time creative intel as clients demand proof of what works—and why.

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

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

Creator marketing will scale in 2026 as brands chase measurable outcomes. At the same time, pressures from AI, shifting platform incentives, and rising automation will reshape how creators earn and grow.

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.

The Omnicom-IPG merger has cleared its last obstacle after the European Commission—the last market whose approval was needed—officially granted greenlit the acquisition. Omnicom and IPG overcoming the final barrier to merge offers the potential for more comprehensive and efficient services—but also introduces new risks related to talent retention and creative diversity.

A Snapchat, Publicis Media, and Ipsos study revealed creator preferences for brand collaborations, outlining the path ahead for brands who increasingly rely on influencer marketing. Accounting for creator preferences is key to striking influencer partnerships that last and make a tangible impact.

WPP cut its full-year outlook after Q3 organic revenue fell 5.9% to £2.46 billion, its steepest quarterly decline since 2020. New CEO Cindy Rose said the company “hasn’t gone fast enough” to meet client needs and outlined a turnaround focused on AI, operational efficiency, and simplifying its agency network. WPP’s slump reflects broader challenges facing holding groups in the AI era: proving value through speed, integration, and measurable results as brands increasingly turn to self-serve, platform-driven ad solutions.

Holding company WPP launched WPP Open Pro on Thursday, a self-serve AI tool piloted by Google and other clients that creates ad campaigns from start to finish in a push to attract small businesses. WPP’s newest move means marketers can continue to expect greater automation, cost savings, and a shift in agency relationships.

The Omnicom-IPG merger is expected to close in November, according to Omnicom CEO John Wren in the company’s Q3 earnings release, which showed organic revenue growth of 2.6% YoY. The merger seems to have crossed its last hurdle—and the new Omnicom-IPG entity stands to benefit marketers in many ways, though brands must keep some considerations in mind.

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.

At Advertising Week New York, creators are no longer side players—they’re center stage. Global president Ruth Mortimer told EMARKETER that influencers now operate as media channels in their own right, shaping programming with four dedicated tracks, a creator lounge, and even an Adobe-backed live pitch where creators can secure $25,000 contracts on stage. As creators revive entertainment formats and build their own businesses, brands should view them as long-term partners driving cultural relevance—not just campaign amplifiers.

Horizon Media and Havas are teaming up in a new $20 billion joint venture, Horizon Global, designed to add scale without a full merger. Headquartered in New York, the entity will focus on U.S.-centric global accounts while Horizon and Havas continue operating independently. Horizon Global unites Horizon’s Blu platform and Havas’ Converged.AI into a new system called BluConverged, billed as the first AI-native media network. The move comes as Omnicom and Interpublic finalize a $13.5 billion merger, intensifying competition across the agency sector. Horizon Global offers clients a more flexible, performance-based alternative to mega-holdcos weighed down by bureaucracy.

Japan-based agency holding company Dentsu is considering selling its international business, ending its goal to compete against rivals Publicis and WPP. Selling its international business could allow Dentsu to reposition itself as a specialized player in its core market rather than stretching itself thin internationally where it can’t match competitors. The change could make the company more sustainable in the long run, but even if it focuses solely on Japan, rapid adoption of emerging technologies in the ad sector will still necessitate innovation.

Accenture Song has acquired Superdigital, a Florida-based social-first and influencer agency with clients including Microsoft, Welch’s, and Nerf.
