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.

Advertising industry, public relations, and related services employment decreased by 800 jobs in September, per delayed data from the Bureau of Labor Statistics. The decline underscores mounting pressures across the ad sector. As industry employment declines, ad professionals need to focus on skill development, adaptability, and networking.

The Trade Desk heads into Q4 facing simultaneous pressure from Amazon’s fast-expanding DSP and agency frustration over its forced migration from Solimar to Kokai. Amazon’s 0–1% fees, new offsite inventory, and closer ties to Omnicom have sparked reports of meaningful budget shifts away from TTD—an inflection point that challenges its premium pricing. At the same time, agencies describe Kokai as unstable and harder to use, with bugs affecting campaign launches during the most execution-heavy quarter of the year. The convergence raises a key question for marketers: Is TTD’s longstanding grip on open-web programmatic still durable, or beginning to loosen?

WPP is reportedly eyeing a merger with holding company Havas and private equity firms KKR and Apollo, per the Times. A merged WPP and Havas would provide more value to advertisers by giving access to a broader mix of services.

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.

Omnicom will retire advertising network DDB as part of its merger with Interpublic Group (IPG), set to close in November, per various reports. For advertisers, the end of DDB carries deeper implications than a simple brand retirement. It represents the erosion of a creative philosophy brands have historically relied on, and advertisers lose a partner that offered a distinct voice and strategy.

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.

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.

The Federal Trade Commission (FTC) approved a consent order to finalize Omnicom’s multibillion-dollar acquisition of Interpublic Group (IPG) on Friday. New conditions state that Omnicom cannot deny ad dollars to publishers for ideological or political beliefs, unless a client specifically instructs otherwise. The FTC being able to put such explicit conditions on two of the largest advertising agencies globally underscores a new era of aggressive conditions in mergers, setting precedent for how regulators can shape corporate conduct beyond traditional remedies.

Junior ad jobs are gradually disappearing as the industry faces upheaval. While overall ad jobs ticked up slightly earlier this year, employment is still trending downward—and younger workers are taking the brunt. Without a pipeline of entry-level talent, agencies risk eroding their long-term relevance.

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.

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.

Q2 2025 earnings highlighted a widening gap among the major advertising holding companies. Publicis Groupe posted 5.9% organic growth and won major accounts from WPP and IPG, including Mars and Paramount. Omnicom remained stable at 3% growth, while Interpublic shrank 3.5% organically but improved margins ahead of its acquisition by Omnicom. WPP fared worst, slashing its full-year forecast and citing client losses and macroeconomic uncertainty. As brands tighten budgets and demand results, winners like Publicis are doubling down on performance and AI tools. The sector is consolidating—and only the most adaptive players are poised to thrive.

The news: Fox News is seeing a rise in ad revenues as advertisers look to curry favor with the Trump administration, per a Financial Times report. Advertisers are hoping to reach “an audience of one,” per Fox’s head of ad sales, after it was revealed that President Trump is a regular viewer of the channel. Our take: Ad spending is becoming increasingly political, influenced by who holds power, what media they consume, and how brands position themselves in a partisan media environment. Brands are increasingly expected to take a stance—even if it means aligning themselves with controversy.

The news: The FTC has conditionally approved Omnicom’s $13.5 billion acquisition of IPG, but with a historic behavioral restriction: the merged ad giant is barred from coordinating ad placements based on political or ideological content. This addresses rising concerns over informal industry efforts to blacklist partisan publishers, especially those on the right. Our take: The ruling sends a clear warning that media buying behavior is under federal scrutiny. While brands can still control where their ads appear, holding companies must now walk a tighter line. The age of unregulated middlemen in ad placement may be ending.

The news: The pending Omnicom Group and Interpublic Group merger is facing a new hurdle, per a New York Times report. The Federal Trade Commission is reportedly considering adding restrictions on Omnicom and IPG that would stop the merger unless the new company agrees to a ban on ad boycotts that would prevent it from refusing to host clients’ advertisements on platforms because of political reasons. Our take: If the FTC proceeds, the decision will have a ripple effect on the advertising industry as a whole, emphasizing that advertisers are increasingly faced with choosing between brand safety and legal pushback.

M&A activity in the marcom space fell 37% in 2024: The decline shows a field in peril—but preparing for a rebound promises success.

WPP Q1 revenues decline 5% YoY: Another disappointing quarter could spell trouble ahead for the company if it doesn’t enhance its value proposition.
