The Federal Trade Commission is in active negotiations with several of the world’s largest advertising firms over allegations they illegally coordinated boycotts targeting conservative media platforms, primarily Elon Musk’s X.
The probe, first reported by The Wall Street Journal, involves ad giants WPP, Publicis Groupe, Dentsu, Havas, and Horizon Media. Investigators are examining whether those firms conspired to collectively pull ad spending from platforms based on the political viewpoints hosted there, a potential violation of federal antitrust law.
Under the proposed settlement terms, participating firms would commit to a “neutral” approach to ad placement. They would be barred from directing client budgets away from media platforms solely because of the political content on those sites. Individual advertisers, however, would retain the right to make their own independent decisions about where their ads run.
The investigation centers on the industry’s “brand safety” framework, a practice advertisers have used for years to avoid placing ads near offensive content. The FTC is now looking at whether major agencies crossed the line by coordinating with outside advocacy groups to systematically cut off platforms from ad revenue.
The push against X accelerated after Musk completed his $44 billion purchase of the platform in October 2022 and began loosening content moderation policies. Within weeks, a wave of major brands paused their spending on the site.
X filed a lawsuit against an ad trade group and several companies, including Mars and CVS, alleging an “illegal boycott.” Last month, however, U.S. District Judge Jane Boyle dismissed the case, ruling that X had failed to establish an illegal conspiracy. The judge found that advertisers shifting their budgets represented market choice, not a violation of antitrust law.
The FTC’s separate investigation takes a different angle, focusing on whether the advertising agencies themselves coordinated with each other, rather than simply individual firms making individual decisions.
A prior settlement reached with Omnicom Group provided a model for what future agreements might look like. Under that deal, Omnicom was prohibited from working with competitors to boycott publishers on ideological grounds, from using or soliciting shared blacklists targeting platforms for political reasons, and from sharing custom client exclusion lists across its client base.
A final deal in the current negotiations has not been reached, the Journal reported. If the FTC succeeds, it would mark one of the federal government’s most direct interventions into the digital advertising market and the relationship between large ad agencies and the platforms that depend on their spending.
