OpenAI Class Action Lawsuit Accuses ChatGPT of Unlawfully Extracting Children’s Data

A parent identified as Jane Doe has sued OpenAI on behalf of her two children, a 12-year-old girl and a 16-year-old boy. The complaint says ChatGPT let minors sign up with one click, never asked their parents for permission, and then used what the children typed to train its models and build profiles of them. She wants the court to certify a nationwide class of everyone in the United States who used ChatGPT as a minor.

The case is Doe v. OpenAI Foundation, et al., No. 3:26-cv-11781, in the U.S. District Court for the Northern District of California, San Francisco Division. It was filed on October 13, 2026, so it is at the very beginning. Nothing has been proven, no class has been certified, and OpenAI disputes the claims.

What Does the OpenAI Children’s Data Class Action Allege?

The complaint starts from OpenAI’s own rules. ChatGPT’s Terms of Use say anyone under 18 needs a parent’s or guardian’s permission, and an OpenAI help article quoted in the complaint says the same for children ages 13 to 18.

The lawsuit says that rule exists only on paper. According to the complaint, creating an account requires a name and an age. If the user says they are 13 or older, a click on “Continue” opens the account. The user is not required to open the Terms of Use, and OpenAI never contacts a parent.

From there, the complaint alleges:

• Children’s data trains the models. Children confide in ChatGPT about health, family, friendships and worries, and OpenAI allegedly uses that material to train its large language models, with some chats potentially reaching human reviewers.
• OpenAI builds profiles of children. Through ChatGPT’s memory feature, it allegedly builds detailed profiles that shape later conversations.
• The design is built to draw children in. The complaint describes a “data flywheel,” where more engagement produces more data, which improves the product and draws more engagement. It points to ChatGPT speaking in the first person, mirroring a user’s style, flattering the user, remembering past chats and ending replies with follow-up questions, and argues adolescents’ developing brains make them especially open to this.
• The defaults favor OpenAI. It alleges training and memory are on by default for children, while business customers are opted out of training by default.
• ChatGPT for Teens does not fix it. OpenAI launched ChatGPT for Teens on August 18, 2026. It lets a parent link to a teen’s account and receive alerts about possible self-harm. The complaint says it does not add parental consent at sign-up, change the Terms of Use or change the default settings, that teens can turn off the parental link, and that parents cannot see chat content.
• Advertising adds value. OpenAI began an advertising program in January 2026. The complaint says OpenAI states it does not place ads to children, but argues the company keeps children’s data indefinitely and can use it for advertising once they turn 18. Plaintiffs say a large part of OpenAI’s reported valuation of more than $1 trillion comes from this data.

All of this is the plaintiffs’ account, not a finding by any court.

What Do the Complaint’s Two Named Children Allege Happened?

The children are identified as MC1 and MC2 to protect their identities.

MC1, a 12-year-old girl, began using ChatGPT in February 2026. The complaint says she started with ordinary questions and homework, then shared selfies and personal concerns about her appearance, weight and diet, and her relationship with her mother. When ChatGPT asked her age and she said she was 12, it allegedly kept responding, even though OpenAI’s terms set 13 as the minimum age.

MC2, a 16-year-old boy, began using ChatGPT in January 2026. The complaint says he used it for homework, relationship advice and uploaded photos of himself and his surroundings.

These are allegations from the complaint. They do not establish that every child’s conversations were used for training or that any design feature is unlawful.

The Legal Theory: Why Does the Lawsuit Say ChatGPT’s Terms Are Void for Minors in California?

This case is unusual for what it does not rely on. It does not rest on a federal children’s privacy statute or a state data protection law. It rests on California rules about who can make a contract. OpenAI is based in San Francisco, and ChatGPT’s Terms of Use choose California law.

What Does California Civil Code § 1568.5 Say?

Civil Code § 1568.5, effective since 2022, says a minor’s representation that a parent or guardian has consented is not treated as consent for purposes of the chapter on minors’ capacity to contract. The complaint argues that OpenAI’s only method of getting parental consent is the child’s own click, which the statute makes ineffective. It asks for a declaration that OpenAI’s parental-consent method is invalid.

What Does California Family Code § 6701 Say?

Family Code § 6701 lists three things a minor cannot do: give a delegation of power, make a contract relating to real property, and make a contract relating to personal property not in the minor’s immediate possession or control. The complaint argues the Terms of Use trip two of these. First, it says the material a child types and uploads is the child’s personal property, and it does not yet exist when the child clicks “Continue.” Second, it says the terms let OpenAI share minors’ data with outside vendors and human contractors, which it calls a delegation of power.

Why Does “Void” Matter Instead of “Voidable”?

Under Family Code § 6710, most minors’ contracts are voidable, meaning valid until the minor cancels them. The plaintiffs say contracts covered by § 6701 are different: void from the start, so no contract was ever formed. The complaint says this suit relates only to § 6701.

If a court agreed, OpenAI could not enforce the terms’ arbitration clause against minors, and the complaint asks for a declaration to that effect. Whether a court will apply these 150-year-old statutes to an AI chatbot’s sign-up flow is the central question in the case. The complaint says it is the first to ask California courts to do so.

What Is the Unjust Enrichment Claim?

The third claim says OpenAI received a benefit from children’s data without paying for it or having valid authorization. In California, unjust enrichment is often treated as a basis for restitution rather than a stand-alone cause of action, so this claim may draw a challenge. The complaint also relies on California property statutes on accession, the idea that the person who takes something and makes it more valuable may have to turn over the improved product. Its illustration is that if someone steals grapes and makes wine, the victim is owed the value of the wine. The complaint cites Civil Code §§ 1031 to 1033 for this, according to published summaries of the filing.

Is This a COPPA Lawsuit?

No. The complaint does not appear to assert a claim under the federal Children’s Online Privacy Protection Act (COPPA), 15 U.S.C. §§ 6501–6506, which governs online collection of personal information from children under 13 and requires verifiable parental consent in covered situations. This case covers a broader group, anyone who used ChatGPT while under 18. For a separate children’s privacy enforcement matter, see TikTok $400 Million COPPA Settlement, Does It Mean Money for Parents?.

What Is the Proposed Class in the OpenAI Lawsuit?

The complaint asks the court to certify a nationwide class of people in the United States who clicked “Continue” on ChatGPT’s Terms of Use while under 18 and then gave OpenAI at least one token of data through ChatGPT, from November 2022 to the present. A token is a small unit of text used to measure AI usage. The usual exclusions apply, including OpenAI, its lawyers and court personnel. The plaintiffs reserve the right to seek state subclasses and argue the limitations period is paused until each class member turns 18. The court has not ruled on any of that.

The class is not every ChatGPT user. Someone who used ChatGPT at 16 and is 19 now could fall within the proposed wording. That does not mean they have been confirmed as a class member or are entitled to compensation. Class certification is governed by Federal Rule of Civil Procedure 23, and the case was filed in federal court under the Class Action Fairness Act, 28 U.S.C. § 1332(d), which requires more than $5 million in controversy and more than 100 class members.

What Is the OpenAI Lawsuit Asking For? The Equity Remedy

The headline remedy is unusual. Instead of asking for a fixed payment, the plaintiffs want each class member to receive a share of OpenAI equity, or its cash value, in proportion to the tokens that child contributed through ChatGPT. The complaint says OpenAI already numbers the tokens associated with each user.

It also asks for restitution, disgorgement of profits, a constructive trust, punitive damages, interest, attorney’s fees and a jury trial. It names no total dollar amount. This is a request, not an award, and no court has approved a formula for what any child would receive.

How Has OpenAI Responded to the Children’s Data Lawsuit?

OpenAI has publicly rejected the case. In a statement reported by Bloomberg Law on October 13, 2026, the company said it strongly disagrees with the “misguided lawsuit,” argued that it singles out OpenAI despite age-specific protections in its products, and warned the case could push teens toward products with fewer safeguards. OpenAI says teen accounts have extra protections and that linked parents can manage settings, including whether a teen’s conversations are used to improve models.

OpenAI’s privacy policy states its services are not directed to children under 13 and that users under 18 must have a parent’s or guardian’s permission. In a separate case, Raine v. OpenAI, the complaint notes OpenAI argued that its Terms of Use prohibit use by anyone under 18 without parental consent. The Doe plaintiffs use OpenAI’s own parental-consent requirement as part of their argument.

I have not found OpenAI’s formal answer or motion in this case. Defendants in this position often file a motion to dismiss or a motion to compel arbitration, but none has been reported.

What Is the Current Status of Doe v. OpenAI Foundation?

On the filing date, the clerk noted that a motion to proceed under a pseudonym had to be filed before a judge would be assigned, and that summonses would not issue until it was granted. Courts in the Ninth Circuit weigh the need for anonymity against public access and prejudice to the defendant before allowing a plaintiff to proceed under a pseudonym (Does I thru XXIII v. Advanced Textile Corp., 214 F.3d 1058 (9th Cir. 2000)); where minors are involved, courts often grant such requests. I could not confirm whether the motion has been decided or a judge assigned as of October 24, 2026.

At this stage:

• No class has been certified.
• No court has ruled that OpenAI illegally collected children’s data.
• No court has declared ChatGPT’s Terms of Use void for minors.
• No court has ordered OpenAI to pay money or transfer equity.
• No settlement or claim process exists.

Key Dates in the OpenAI Minors’ Data Lawsuit

Do You Need to File a Claim in the OpenAI Lawsuit?

No. There is no claim form, deadline or settlement fund. In a putative class action, people who fit the proposed definition generally do not have to sign up. If a class is certified or the case settles, class members would normally receive notice with instructions. Be skeptical of any site that says you can claim a share of OpenAI now, and do not pay anyone to “register” for a settlement that does not exist.

Other Laws That Bear on Children’s Data and AI Chatbots

Because this case rests on contract law, other children’s privacy laws sit around it rather than inside it:

• COPPA (described above) covers children under 13 and is enforced by the Federal Trade Commission and state attorneys general. It does not give individuals a private right to sue.
• The California Consumer Privacy Act, Civil Code § 1798.100 et seq., requires opt-in consent before a business sells or shares personal information of consumers under 16, with parental consent for those under 13 (§ 1798.120). It is not part of this complaint.
• State consumer protection laws have been used by attorneys general in other youth-technology cases. For a related example, see Meta State AG Child Safety Bellwether Trial.

How Is This Case Different From Other OpenAI Lawsuits?

OpenAI faces several separate cases. This one concerns children’s data, parental consent and contract validity. It is distinct from family lawsuits alleging ChatGPT contributed to serious psychological harm, covered in OpenAI’s ChatGPT Faces a Wave of Child Harm Lawsuits as It Heads Toward a Record IPO. It is also different from the tracking-based privacy case covered in OpenAI Class Action Lawsuit, ChatGPT Allegedly Sent Your Private Queries to Meta and Google, and from the case about outside contractors reviewing conversations, covered in OpenAI ChatGPT Human Review Lawsuit, Were You Affected? Vredenburgh, et al. v. OpenAI OpCo LLC, No. 3:26-cv-10527. The parties, theories and remedies differ, and a result in one does not decide the others.

What to Watch Next in Doe v. OpenAI Foundation

• The pseudonym motion and judge assignment. The case cannot move until the court resolves these.
• OpenAI’s first response. A motion to dismiss or compel arbitration would test the “void from the start” theory early.
• How the court reads § 6701. The question is whether a chatbot’s sign-up terms fall within the contracts a minor cannot make at all, rather than the voidable contracts California usually allows.
• Class certification. A nationwide class of minors across several years would be a major hurdle.

Frequently Asked Questions About the OpenAI Children’s Data Lawsuit

Why is OpenAI being sued over children’s data?

The complaint alleges OpenAI collected and used information children shared through ChatGPT without legally effective parental consent, and that ChatGPT’s design encouraged children to share personal details that benefited OpenAI’s models and business.

Who filed the OpenAI class action?

Jane Doe filed on behalf of her minor children, MC1 and MC2, and a proposed nationwide class of people who used ChatGPT while under 18.

Which companies are defendants?

OpenAI Foundation (formerly OpenAI, Inc.), OpenAI OpCo, LLC, OpenAI Holdings, LLC and OpenAI Group PBC.

How much money could children receive?

The plaintiffs ask for an equity share in OpenAI or its cash value, plus restitution and other relief. No amount has been awarded and no per-child payment has been set.

Can adults who used ChatGPT as teenagers be included?

Possibly under the proposed definition, which turns on being under 18 when they clicked “Continue” and provided data. The class has not been certified.

Does the lawsuit ban children from ChatGPT?

No. It challenges the legality of the consent process and the use of minors’ data. Any change would require a court ruling or an approved settlement.

Has OpenAI admitted wrongdoing?

No. OpenAI has publicly disagreed with the lawsuit.

Is this a class action I can join?

It is a putative class action, meaning the plaintiffs have asked to represent a class the court has not certified. There is nothing to sign up for.

The Bottom Line on the OpenAI Children’s Data Class Action

The lawsuit argues that a child clicking “Continue” cannot replace legally effective parental consent under California law, that ChatGPT’s Terms of Use are therefore void for minors, and that OpenAI should share the value it gained from children’s data. It asks for declarations and an unusual remedy: a share of OpenAI’s equity.

The case is at its earliest stage. No court has certified a class, found OpenAI liable or awarded anything. The first things to watch are how the court handles the pseudonym request and how OpenAI responds.
