FTC Targets Ad Giants Over Brand-Safety Collusion, Breitbart and X Claims

The Federal Trade Commission’s settlement drive against WPP, Publicis and Dentsu could redraw the line between ordinary brand protection and politically risky discrimination, putting advertisers, platforms and publishers nationwide on notice that decisions about where ads appear may now face antitrust scrutiny. The agency and eight states, Florida, Indiana, Iowa, Montana, Nebraska, Texas, Utah and West Virginia, said the case challenges a system that allegedly let major ad buyers coordinate on who could be funded and who would be cut off.

Filed in federal court in Fort Worth, Texas, the complaint says the companies began colluding in 2018 to impose common brand-safety standards across digital advertising, using trade groups including the Global Alliance for Responsible Media and the American Association of Advertising Agencies’ Advertiser Protection Bureau. The FTC said the firms built a shared Brand Safety Floor and leaned on misinformation labels, including those promoted by groups such as NewsGuard and the Global Disinformation Index, to help demonetize disfavored political viewpoints. The agency said the effect was to distort competition in the ad-buying market and, more broadly, the marketplace of ideas.

The case lands in the middle of a wider fight over how much discretion advertisers should have to avoid controversial placements. The FTC said its concerns included ad placement on Elon Musk’s X and on Breitbart, a conservative site that has become a flashpoint in debates over brand safety and viewpoint discrimination. Under the proposed orders, the firms would be barred from using exclusion lists or coordinating future political or ideological advertising restrictions.

The action also follows the collapse of GARM, which the World Federation of Advertisers created in 2019 after the Christchurch mosque shootings to help brands avoid harmful content. GARM said its tools reduced ads appearing alongside harmful or illegal content from 6.1% in 2020 to 1.7% in 2023, but the group said in August 2024 that it would discontinue activities after X sued it over an alleged advertiser boycott.

Reuters reported that the settling firms did not admit wrongdoing. Dentsu said it was committed to operating transparently and in compliance with the law, while WPP said it would give clients unbiased advice on ad placement. Publicis did not immediately comment. The settlement also comes after the FTC’s June 2025 approval of Omnicom’s $13.5 billion purchase of Interpublic, which included a condition barring the combined company from steering ad dollars toward or away from media based on political content.
