X Corp. Drops Antitrust Appeal as Advertisers Commit to Permanently Retire GARM

X Corp. and the World Federation of Advertisers (WFA) have formally resolved their legal confrontation, bringing an end to a high-stakes antitrust dispute over corporate advertising boycotts and digital platform moderation.

Under the terms of the settlement, X agreed to drop its appeal against an earlier federal court ruling that had dismissed the suit. In exchange, the WFA confirmed it will not attempt to revive the Global Alliance for Responsible Media (GARM) or create any equivalent coalition aimed at organizing ad buyers against specific platforms.

The legal clash originated in 2024, when X sued the trade body alongside prominent corporate ad buyers—including Adidas, Mars, Mastercard, NBCUniversal, Procter & Gamble, Unilever, and Vodafone. X alleged that these companies orchestrated an illegal boycott that deprived the platform of billions of dollars in revenue after its content moderation policies were overhauled. Digital platforms rely heavily on ad dollars, making coordinated pullouts financially destabilizing.

GARM was established by the WFA in 2019 as an industry-wide safety initiative designed to set baseline standards preventing corporate ad placements alongside harmful content. Shortly after X initiated legal proceedings, the WFA shut GARM down. Establishing liability under federal antitrust regulations on group boycotts requires plaintiffs to prove actionable commercial injury, a threshold the judge ruled X failed to meet when dismissing the initial suit earlier this year.

With the appeal now abandoned, both organizations released a joint statement signaling a shift toward collaboration on brand safety, with the WFA referencing its 1953 constitutional commitment to free speech.
