FTC Orders WPP, Publicis, Dentsu to Stop Collusion
The U.S. Federal Trade Commission and several states reached a settlement with advertising holding groups WPP, Publicis and Dentsu over allegations that, beginning in 2018, the agencies illegally coordinated to impose brand safety standards that steered advertiser budgets away from certain platforms and publishers. The government found the coordination produced an effective boycott of conservative media platforms. FTC Chair Andrew Ferguson said the alleged brand‑safety conspiracy distorted competition in the ad‑buying market and violated antitrust laws.
A major regulatory enforcement and settlement involving the largest agency holding companies affects industry-wide brand safety practices, antitrust risk, and how media budgets are directed—potentially reshaping agency behavior and publisher access.

FTC Settlement Talks with Agencies; Meta Suit; YouTube Price Hike
The FTC is negotiating a potential settlement with several major advertising groups — including Publicis Groupe, WPP, Dentsu, Havas and Horizon Media — over an antitrust probe into whether they coordinated advertiser boycotts of platforms such as X. Under the proposed terms, firms would be restricted from steering client budgets away from platforms based on political or ideological content while preserving individual advertiser choice. Separately, the Massachusetts Supreme Judicial Court ruled that Meta must face a youth addiction lawsuit brought by Attorney General Andrea Joy Campbell, with Justice Dalila Argaez Wendlandt finding the claims target platform design rather than third-party content. Finally, YouTube will raise US Premium subscription prices in June, increasing individual plans by $2 to $15.99 and family plans by $4 to $26.99, with smaller increases for Lite and Music tiers.
X settles multiyear lawsuit with WFA
X Corp and the World Federation of Advertisers (WFA) announced on July 29, 2026 that they have settled a multiyear antitrust dispute stemming from X’s August 2024 lawsuit. X alleged the WFA, its Global Alliance for Responsible Media (GARM) and several major advertisers coordinated a boycott that diverted ad spend from X and deprived it of revenue. A federal judge in Texas dismissed the case on March 26, 2026 for failure to show the required antitrust injury; X appealed. The WFA discontinued GARM on August 9, 2024 and said it will not re-form a similar initiative. In a joint statement the parties said they are putting the litigation behind them, removing legal uncertainty while expressing interest in pursuing new brand-safety approaches.
Publicis and The Trade Desk Reach Détente
Publicis Groupe and The Trade Desk have publicly reconciled after a high‑profile dispute that began in March when Publicis pulled The Trade Desk following an audit that flagged alleged fee‑stacking irregularities. A June 12 statement said the pair are focused on moving forward and Publicis has reinstated The Trade Desk to its recommended DSP list; terms of the resolution were not disclosed. Digiday frames the episode as symptomatic of a wider industry shift: agency holding companies (Publicis Marcel, Omnicom’s Omni, WPP Open) are building proprietary technology stacks that increasingly overlap with traditional ad tech vendors. Competition among DSPs is intensifying — buyers still rate The Trade Desk highly but report growing use of Amazon, Yahoo, StackAdapt, Viant and others — while emerging AI capabilities and agency AI platform claims raise new questions about data ownership, governance, and who controls decisioning layers for advertisers.
