A US federal judge has dismissed Elon Musk's antitrust lawsuit against advertisers who stopped spending on X, ruling the company failed to state a valid legal claim. The lawsuit accused advertisers of conspiring to withhold advertising revenue due to X's brand safety standards, but the court found no evidence of an illegal boycott. The judge's decision, which bars X from refiling the case, marks a significant legal setback for Musk's efforts to compel advertising spending. The ruling confirms that companies are not legally obligated to advertise on any particular platform, and declining to do so is not an antitrust violation.
