The Amazon antitrust cases are proceeding, not settling. No settlement fund, claim form, or payout is available now. Class certification means the court lets a large group seek damages together.
Judge John H. Chun certified the De Coster class on Aug. 6, 2025, covering about 288 million consumers who bought five or more new physical goods from Amazon third-party sellers since May 26, 2017, according to LegalClarity's guide on how to join and claim.

What did certification decide?
Certification allows collective damages claims without deciding liability. That point matters because shoppers may read certification as a win on price-fixing.
It is only permission to litigate as a class. Plaintiffs allege Amazon used pricing restrictions and enforcement to discourage merchants from offering lower prices elsewhere, inflating rival-marketplace prices, as described by PYMNTS' report on the price-inflation allegations. The court rejected Amazon's argument that unprecedented class size made classwide litigation unmanageable.
Who is covered in each case?
De Coster covers Amazon third-party buyers. Frame-Wilson covers buyers on rival marketplaces for the same period of alleged conduct.
Chun issued a 56-page order on Nov. 2, 2026 granting certification with a minor modification in Frame-Wilson, according to Hagens Berman's case update. That class covers persons since March 19, 2016 with at least two Walmart third-party purchases or at least four eBay third-party purchases of new physical products concurrently sold by the same seller on Amazon.
What is Amazon appealing?
Amazon is seeking U.S. Court of Appeals for the Ninth Circuit permission to immediately appeal the Frame-Wilson certification ruling. Permission is not automatic. The request challenges whether the class should proceed together, not whether Amazon violated antitrust law.
An appeal request does not create a claim deadline. De Coster has not settled, with notices addressing staying in versus opting out by Aug. 31, 2026. Shoppers in Frame-Wilson should watch for separate court-approved notice about their rights and deadlines.
Should you file a claim now?
No. There is no approved claim form to file.
Filing a vendor form or third-party payment site will not place you in the payout line. Trial is currently scheduled for June 14, 2027 after moving from October 2026 to avoid overlap with a California attorney general enforcement action, according to LegalClarity's guide on how to join and claim.
