The news: The pending Omnicom Group and Interpublic Group merger is facing a new hurdle, per a New York Times report.

The Federal Trade Commission (FTC) is reportedly considering adding restrictions on Omnicom and IPG that would stop the merger unless the new company agrees to a ban on ad boycotts that would prevent it from refusing to host clients’ advertisements on platforms because of political reasons. The move is part of a broader effort from the Trump administration to deter what it deems bias against conservative beliefs.

Zooming out: Omnicom and IPG first announced merger plans in December that would create an advertising behemoth with $25 billion in annual revenues—one of the largest mergers in advertising history.

But while Omnicom and IPG expected the merger to come in the second half of 2025, the FTC’s latest push against ad boycotts could complicate things, as the update comes amid a sea of struggles for advertisers navigating a volatile political climate.

• Most recently, the FTC began investigating advertising groups and watchdogs to determine whether they violated antitrust laws through coordinated boycotts on platforms like X, which FTC chairman Andrew Ferguson claimed amounted to censorship of conservative voices.
• Advertisers also sought dismissal of an X lawsuit that alleged a coordinated boycott of the platform that X argued made it “a less effective competitor to other social media platforms.” Advertisers asserted that even if the claims were true, they would not establish evidence of a coordinated effort.
• The US House Judiciary Committee previously investigated the Global Alliance for Responsible Media over claims that it limited conservative content online—leading to GARM ending its operations.

Why it matters: Omnicom and IPG are two of the largest advertising agencies globally. The FTC scrutinizing the companies for potentially coordinating future boycotts emphasizes that all advertisers are navigating a slippery slope, where holding back spending can be construed as a targeted boycott—raising serious implications for how brands and agencies approach decisions related to brand safety and content alignment.

Our take: If the FTC proceeds, the decision will have a ripple effect on the advertising industry as a whole, emphasizing that advertisers are increasingly faced with choosing between brand safety and legal pushback.

• Boycotts—or actions that could be perceived as a boycott—are becoming riskier, forcing brands to reassess how they balance moral beliefs with regulatory compliance.
• Advertisers could need to formalize internal guidelines around marketing and political neutrality to avoid pushback when making platform-related ad decisions. Future mergers could hinge on how ad agencies approach platforms and choose where to spend.
