FTC Targets Ad Agencies Over Coordinated Brand Safety Boycott

The Federal Trade Commission moved to block ad agencies from coordinating brand-safety rules it says helped steer dollars away from politically disfavored platforms, putting antitrust law at the center of a fight over online speech and ad-market power.

The agency, joined by Florida, Indiana, Iowa, Montana, Nebraska, Texas, Utah and West Virginia, announced a proposed settlement with major advertising firms that would bar them from working together to avoid certain platforms like X because of their political viewpoints. The complaint says the conduct began in 2018 and involved WPP, Publicis and Dentsu, with Omnicom and IPG also named as part of the industry network that enforced a common floor for acceptable ad placements.

At the heart of the case is the idea of a shared “brand safety” standard. The FTC says the agencies used trade groups including the World Federation of Advertisers’ Global Alliance for Responsible Media and the American Association of Advertising Agencies’ Advertiser Protection Bureau to establish those rules, then relied on organizations such as NewsGuard and the Global Disinformation Index to push demonetization of viewpoints they considered disfavored. The 4As says the APB launched in 2018, with founding members that included leaders from dentsu, GroupM, Havas Media, Horizon Media, IPG Mediabrands, MDC Partners, Omnicom Media Group and Publicis Media.

If that coordination ends, the practical effect could be immediate inside the digital ad market. Agencies buying inventory for advertisers would no longer be able to rely on a shared industry screen that excluded certain outlets across the board. That could send more ads to contentious publishers and platforms, while shifting reputational risk back onto individual agencies and brands that choose where to spend. It also means the government is not just policing prices or output, but pressuring private actors to stop using a collective content filter that the FTC says distorted the “marketplace of ideas.”

FTC Chairman Andrew N. Ferguson said the agencies’ conduct “turned competition in the market for ad-buying services on its head” and distorted the “marketplace of ideas” by discriminating against speech and ideas below the agreed-upon floor. The proposed order would stop the alleged coordinated conduct and bar similar behavior in the future, as the commission extends its broader campaign to challenge coordination in digital advertising and restore competition in the digital news ecosystem. The companies did not admit wrongdoing in agreeing to settle.
