FTC Orders WPP, Publicis, Dentsu to End Brand Safety Collusion
The FTC orders three major ad holding companies to end coordinated brand safety restrictions that discriminated against publishers based on political viewpoint. A landmark antitrust settlement reshaping how agencies advise clients on ad spending.
The U.S. Federal Trade Commission announced proposed antitrust settlements with three of the world's largest advertising holding companies on April 16, 2026, ordering WPP, Publicis, and Dentsu to stop coordinating restrictions on ad spending based on publishers' political viewpoints.
Settlement Terms Cover Eight Years of Alleged Coordinated Conduct
The FTC concluded that the three agencies illegally coordinated brand safety standards dating back to 2018, effectively directing advertiser budgets away from certain media outlets. The alleged coordination operated through two industry bodies: the World Federation of Advertisers' Global Alliance for Responsible Media (GARM) and the American Association of Advertising Agencies' Advertiser Protection Bureau (APB).

Under the consent orders, agencies are prohibited from factoring in a publisher's political viewpoint, adherence to third-party journalistic standards, or DEI commitments when directing ad buys, unless a client explicitly instructs them to do so. Blacklists and whitelists also require documented client approval. Agencies are additionally subject to court-appointed compliance monitors, creating ongoing legal exposure for procurement teams.
FTC Chair Andrew Ferguson stated: "The ad agencies' brand-safety conspiracy turned competition in the market for ad-buying services on its head," adding that the conduct "distorted the marketplace of ideas by discriminating against speech and ideas."
WPP said it was "pleased to finalise this agreement with the FTC which reflects our existing and ongoing commitment to provide our clients with unbiased advice." Dentsu emphasized transparency and compliance. Publicis declined to comment.
Five Holding Companies Now Subject to FTC Brand Safety Orders
The April 2026 settlements follow a broader enforcement sequence that swept in all five major advertising holding companies. The FTC first applied viewpoint-based ad restriction prohibitions to Omnicom as a condition of its US$13.5 billion acquisition of IPG, approved in September 2025. That merger approval established the regulatory template later extended to WPP, Publicis, and Dentsu.
The proposed orders were filed in the U.S. District Court for the Northern District of Texas, with eight state attorneys general joining the action: Florida, Indiana, Iowa, Montana, Nebraska, Texas, Utah, and West Virginia. The settlement passed on a 1-0-1 FTC commission vote, with Commissioner Meador recused.
The FTC's broader investigation, launched in June 2024, also named media rating firms including NewsGuard, Media Matters for America, Ad Fontes Media, and Integral Ad Science as organizations whose standards were allegedly used to demonetize publishers based on political viewpoint.

GARM Closure and NewsGuard Counter-Litigation Create Parallel Pressures
GARM was shut down following a lawsuit by Elon Musk's X against GARM and the World Federation of Advertisers, which alleged the organizations pressured advertisers into platform boycotts. The lawsuit, combined with a 2024 congressional investigation finding that GARM members withheld ad spending from Fox News, The Daily Wire, and Breitbart, directly preceded the FTC enforcement action.
NewsGuard has filed a separate lawsuit against the FTC, disputing the agency's characterization of its methodology. "This is supposed to be a collusion case, but we don't work with the ad agencies signing the consent order and our ratings are based on non-partisan journalistic standards, not political orientation," the company stated.
The proposed orders are subject to a 30-day public comment period before taking effect. The FTC stated it continues investigating other firms connected to the alleged conduct.
