Between the lines. The Supreme Court’s decision lets stand a March 2024 ruling from the 9th Circuit Court of Appeals, which said advertisers could pursue damages as a group since Meta’s alleged misrepresentation was consistent across all affected parties.
Meta’s argument. The tech giant claimed that different advertisers may have valued or relied on the reach metrics differently, thus leading to the inflation they see.
Meta also said that the 9th Circuit’s “common course of conduct” test conflicts with other federal courts.
What’s next. The case will now proceed as a class action, potentially affecting millions of Meta advertisers who bought ads over the past decade.
Go deeper. Advertising revenue remains Meta’s primary business driver, making the outcome of this case particularly significant for the company’s future.
