If you bought five or more items from third-party sellers on Amazon since May 2017, you are automatically in this certified ~288 million-person class — here is how to stay in or opt out by August 31, 2026.
Am I Included in the Amazon Class Action?
You are in the certified class if you are a person in the United States who, on or after May 26, 2017, purchased five or more new, physical goods from third-party sellers on Amazon's Marketplace. The class covers roughly 288 million people — one of the largest classes ever certified. Orders that show "Sold by Amazon" are not third-party purchases and do not count toward the five-item threshold.You do not need to sign up or prove anything to be a class member. If you fit the definition, you are already in the class automatically.

Class Notice Is Live — What That Means
In June 2026 the case moved into the class-notice phase. The court appointed Epiq as the notice administrator, and an official court-approved website is now live at AmazonAntitrustLitigation.com. Notices began going out on June 1, 2026.Notice does not mean Amazon has agreed to pay anyone. It means the court is formally telling class members the case exists, that they are included, and how to exclude themselves if they choose. Amazon denies any wrongdoing and the case is still headed to trial.

Is the Notice You Received Real?
With notices going to roughly 288 million people, many recipients are asking whether the email or postcard is a scam. It is legitimate if it comes from the court-approved administrator, Epiq, and points to the official site, AmazonAntitrustLitigation.com. A real class notice will never ask you to pay a fee, hand over your Social Security number to "verify" eligibility, or send money to release a payment — there is no payment in this case yet.If a message asks for any of that, treat it as a scam. When in doubt, don't click the link in the message — type the official web address into your browser yourself.
Should I Stay In or Opt Out? (Deadline August 31, 2026)
You have two choices right now, and only one of them requires you to act:• Stay in the class: do nothing. You remain a class member automatically and keep the right to share in any money if the case is won or settled later.
• Opt out (exclude yourself): follow the exclusion instructions on the official notice website. Your request must be postmarked by August 31, 2026. Opting out means you give up any share of a future recovery, but you keep the right to sue Amazon separately over these claims.
For most people there is no reason to opt out unless they intend to pursue their own individual lawsuit. If you do nothing, you stay in.
Is There a Claim Form or Money Yet?
No. There is no settlement, no claim form, and no payments at this stage. A claim form would only be created if the plaintiffs win at trial or Amazon agrees to a settlement, after which the court would approve a claims process. Trial is currently scheduled for June 14, 2027 (moved back from October 2026).If you ever see a site claiming you can already file a claim for money in this case, treat it as unofficial — the only legitimate site right now is the court-approved notice page, and it does not collect claims.
How Much Could I Get Paid?
It is too early to know. Any payout depends on the size of a future settlement or judgment and how many valid claims are filed. With a class this large, per-person payments are often modest unless the total recovery is substantial — though federal antitrust damages can be tripled, which raises the ceiling.Official Certification Order
