The 2024 Texas filing followed a post-Twitter takeover revenue drop, with brands pausing or reducing ad spend on X.

Originating in August 2024, the suit alleged anti-competitive conduct and coordinated boycotts by international advertiser groups.

The ruling emphasizes that consumer harm is central to antitrust injury; mere collaboration among advertisers without proven consumer impact does not establish an antitrust violation.

Separately, X, now tied to xAI, faces broader challenges over AI tools, moderation policies, and platform safety.

GARM, WFA’s initiative, aims to prevent advertising funding of illegal or harmful content while promoting brand safety and competition among platforms.

X has sought to regain advertiser trust with brand-safety measures and tools like topic-based block lists, though official comment was not provided in the report.

The case spotlighted concerns about advertising transparency and coordination in response to platform content-policy changes and potential revenue impacts for social networks.

Defendants argued advertising decisions were independent, not conspiratorial, and the court agreed no unlawful cartel existed.

Defendants, including CVS and others, denied coordinated wrongdoing and asserted independent ad decisions.

The judge accepted that the defendants acted independently and did not conspire with X.

The article notes X’s post-takeover struggles to maintain ad revenue despite the dismissal of the lawsuit.

A U.S. District Judge dismissed Elon Musk's X Corp lawsuit accusing a group of advertisers, including Unilever, Mars, Orsted and the World Federation of Advertisers, of illegally boycotting the platform and harming its ad revenue.
