Costco Class Action Lawsuit — Sign Up Guide (2026)

You don't “sign up” for a Costco class action in advance — if you're an eligible customer, you're automatically a class member, and you file a claim when a settlement opens. Here's how joining and claiming actually work for Costco in 2026, which cases are active, and how to catch the next payout.

Which Costco class actions are active in 2026?

• Orgain protein-powder heavy-metals lawsuit (2026) — a newly filed case alleges the Orgain protein powder Costco sells contains undisclosed lead, cadmium and arsenic. It's a new lawsuit, not a settlement, so there's no claim yet. Read our Costco Orgain lawsuit page.
• Membership auto-renewal claims — state-specific cases over automatic renewal disclosures.
• Website data-privacy tracking — ongoing.

Am I eligible? (Sign-up criteria)

Eligibility depends on the case — typically Costco members or shoppers during the class period. You usually don't need to prove a specific dollar loss for privacy and pricing cases — being a Costco customer during the covered window is often enough. The court-approved notice defines the exact class.

How to “sign up” (file your Costco claim)

1. Confirm a settlement is actually open for claims (see the case list above).
2. File on the official settlement administrator's website, or let Class Action Buddy auto-fill the claim from your saved profile so you just review and sign.
3. Choose a payment method — digital options pay faster than a mailed check.
4. Submit before the deadline. You submit your own claim; we only prepare the form.

What if I never got a Costco notice?

You can still be a class member without a notice — administrators only have contact details for some customers. Check the official settlement site's class definition, or use Class Action Buddy to see cases you likely qualify for based on your history.

How much do Costco class actions pay?

It varies by case, and none of the current Costco consumer cases has opened a claim window yet, so amounts aren't final. Privacy and pricing settlements usually pay a modest per-person amount with no proof required.

Common questions

Can I sign up for a Costco class action in advance?

You don't register ahead of time. If you're an eligible Costco member, you're automatically a class member and file a claim once a settlement opens a claims window.

Is there an open Costco claim I can file right now?

Not currently. The Orgain protein-powder case is a newly filed lawsuit (no settlement or claim form yet), and the membership and privacy cases have no open claim window.

What is the Costco Orgain lawsuit about?

A 2026 lawsuit alleges the Orgain Organic Protein powder sold at Costco contains undisclosed lead, cadmium and arsenic. There is no recall and no settlement; the allegations are unproven and Orgain says its products are safe.

How do I join the next Costco settlement?

Keep your Costco purchase history (tied to your membership) and watch for an official notice. Class Action Buddy tracks Costco cases and alerts you when a settlement opens that you qualify for, then auto-fills the claim for you to review and submit.
