Ad markets face regulatory pressure

U.S. and European regulators are pressing deeper into the ad business, where a handful of firms help decide which sites get billions in marketing dollars. (reuters.com 1) (reuters.com 2) In the United States, the Federal Trade Commission is in settlement talks with major ad companies over a probe into whether they coordinated boycotts against platforms including X, according to a Wall Street Journal report carried by Reuters on April 12. Reuters said the talks involve potential antitrust claims and that no deal is guaranteed. (reuters.com) Reuters reported in June 2025 that the agency had sought information from Omnicom, WPP, Dentsu, Interpublic Group, Publicis Groupe, Havas and Horizon Media as part of that investigation. The Wall Street Journal report said the inquiry began in 2025 and examined whether agencies steered client spending away from some publishers in concert rather than through separate client decisions. (reuters.com 1) (reuters.com 2) Media buying is the business of pooling many brands’ ad budgets and negotiating with publishers over price, placement and sponsorships. The Federal Trade Commission said in June 2025 that Omnicom and Interpublic were the third- and fourth-largest media-buying agencies in the United States when it imposed conditions on their $13.5 billion merger. (ftc.gov) That merger order showed how the agency is framing the issue. The Federal Trade Commission said its final September 2025 order barred Omnicom from denying ad dollars to publishers based on political or ideological viewpoints unless an individual client specifically directed it to do so, and said its complaint alleged agencies had coordinated through industry associations on decisions not to advertise on certain websites and apps. (ftc.gov) The boycott fight has been building since August 2024, when X sued the World Federation of Advertisers and members of its Global Alliance for Responsible Media, accusing them of organizing an illegal advertiser boycott. Three days later, the World Federation of Advertisers said it would discontinue the Global Alliance for Responsible Media initiative. (techcrunch.com) (marketingweek.com) Europe is moving on a parallel track. On April 13, 2026, Anthony Whelan was appointed director-general of the European Commission’s competition unit, known as Directorate-General for Competition, after serving as a senior adviser to Commission President Ursula von der Leyen and as deputy director-general in the same department. (politico.eu) (commission.europa.eu) Whelan takes over after the Commission began using its newer digital rulebook against platform business models that depend on advertising and app distribution. On April 23, 2025, the Commission fined Apple 500 million euros and Meta 200 million euros under the Digital Markets Act, saying Apple restricted steering in the App Store and Meta failed to offer a less personalized alternative to users who refused data combination. (ec.europa.eu) The two fronts are not identical: the U.S. case centers on whether agencies and trade groups coordinated where ads should not go, while the European cases focus on whether dominant platforms set rules that lock in ad and app revenue. But both fights reach the same choke point in digital advertising: who gets access to audiences, and on what terms. (ftc.gov) (ec.europa.eu) The next test is whether regulators turn that scrutiny into binding orders. In Washington, the settlement talks could end with conduct limits and no admission of wrongdoing; in Brussels, Whelan inherits an office already issuing fines and merger rulings that shape how ads, apps and data move across the market.
