X ends advertising boycott lawsuit with WFA

X Corp. and the World Federation of Advertisers (WFA) have agreed to end their court fight over allegations of an advertising boycott, closing a dispute that began in 2024. In a joint statement, the companies said they want to restart their relationship and leave the conflict behind.

The settlement ends the legal case as well as X’s appeal. It does not mean that major advertisers will immediately restore their spending on the platform, and neither side has announced financial terms for the agreement.

Why X sued the World Federation of Advertisers

X filed the lawsuit against WFA and several of its members in 2024. The platform argued that advertisers had coordinated their decision to stop buying ads on X in response to concerns about content moderation and changes to the platform’s policies.

X characterized the alleged coordination as unlawful and said it had deprived the company of billions of dollars in advertising revenue. The dispute was not simply about individual brands choosing not to spend. X’s case depended on proving that advertisers had acted together in a way that violated antitrust law and caused measurable harm.

The lawsuit also focused attention on GARM, a WFA initiative created in 2019 to bring major advertisers together around brand safety. Its members included Adidas, Mars, Mastercard, NBCUniversal, Procter & Gamble, Unilever, and Vodafone.

GARM’s stated purpose was to help brands avoid appearing next to toxic or misleading content. X, however, treated the collaboration itself as the central problem, arguing that coordinated brand-safety decisions could become collective pressure against a platform.

Court rejects X’s damages case

Earlier this year, a court sided with the defendants and dismissed the case. X failed to demonstrate harm under the applicable antitrust standard, according to the source. The company subsequently appealed, but has now withdrawn that appeal as part of the agreement with WFA.

That ends the most prominent legal phase of the dispute without a ruling from an appeals court. The outcome underscores the difference between making a public allegation of coordinated advertiser action and proving the resulting damage to the demanding standard required in a US antitrust case.

The WFA’s response goes beyond ending the litigation. The association has promised not to revive GARM and not to launch a similar organization. Brand-safety discussions will continue, but the decision removes the specific industry structure that X had made a target of its lawsuit.

What the agreement changes for X and advertisers

For X, the deal removes one of the most damaging public conflicts between the platform and the advertising industry. It gives the company an opportunity to reopen discussions with brands that want clear safety rules and fewer reputational surprises, without an active lawsuit hanging over those conversations.

The agreement is not a court victory for X, and it does not establish that the alleged advertising boycott occurred. It also does not guarantee that advertising budgets will return. The platform’s commercial recovery will depend on whether brands are willing to buy placements again, as well as on its reach and moderation policies.

WFA’s decision reflects a practical constraint on industry alliances. Advertising groups and safety initiatives are increasingly exposed to scrutiny from platforms and regulators when their members appear to act in concert. After the GARM dispute, similar efforts are likely to face closer legal attention, even though the source does not say that WFA plans any replacement program.

For now, the settlement gives both sides a way to reset relations. The next advertising sales cycle—not the settlement itself—will show whether that reset produces any measurable change in X’s revenue.
