Yes, the lawsuit was filed—but the allegations remain disputed, and no court has ruled that they are true or false. Annie Altman sued her brother, OpenAI CEO Sam Altman, in federal court on January 6, 2025, alleging sexual abuse during her childhood. Sam Altman and his family called the allegations “utterly untrue.”
A March 20, 2026 court order dismissed Annie’s initial common-law claims as time-barred but allowed her to amend the complaint under Missouri’s childhood-sexual-abuse statute. The ruling was procedural; it was not a verdict on what happened.

The lawsuit alleged that Sam sexually abused her while they were children. Those allegations appeared in a legal complaint and have not been established as facts by a court.

The case’s later procedural history is set out in the court’s March 20, 2026 memorandum and order.
What did Annie Altman allege?
According to the complaint, Annie and Sam are biological siblings who lived together in the family home in Clayton, Missouri. The court’s order summarized the complaint as alleging that the conduct began around 1997, when Annie was approximately 3 and Sam was approximately 12, and continued until about 2006.
The complaint described alleged sexual touching and other forms of sexual abuse, including allegations characterized in the filing as oral sex, molestation, sodomy, rape, sexual assault, and sexual battery. These descriptions are included only to explain the legal claims; they are allegations made by Annie, not judicial findings.

It sought monetary damages, but conflicting secondary reports gave different figures, so no exact amount is stated here.
How did Sam Altman and his family respond?
Sam Altman denied the allegations. In a joint family statement reported by The Verge, family members called the claims “utterly untrue.”
The family also said it had tried to support Annie financially and in other ways. It disputed aspects of her account and raised claims about her mental-health challenges and treatment. Those statements are the family’s assertions, not findings by the court, and they do not independently establish whether Annie’s allegations are true or false.
What did the court decide on March 20, 2026?
The judge ruled on motions to dismiss. The order:
- Dismissed Annie’s common-law claims as time-barred. The court concluded that the applicable limitations period barred those original claims.
- Allowed Annie to amend her complaint. The court explained that Missouri’s childhood-sexual-abuse statute creates a distinct statutory cause of action and limitations framework. Annie was ordered to file an amended complaint by April 3, 2026.
- Did not decide the truth of the abuse allegations. The court did not conduct a trial, weigh evidence, make credibility determinations, or find that abuse did or did not occur.
- Allowed Sam’s counterclaims to proceed past the pleading stage. His claims for abuse of process and defamation were not dismissed at that point.
- Struck Sam’s request for attorney fees and costs. The order reflects that he agreed to withdraw that request.
Why does “time-barred” matter?
A claim being time-barred generally means the court concluded it was filed after the applicable legal deadline. That is different from deciding that the underlying events did not happen.
The court also distinguished Annie’s original common-law claims from a statutory claim under Missouri’s childhood-sexual-abuse law. Allowing an amendment gave her a possible route to continue pursuing the matter under that statutory framework, subject to later legal challenges and requirements.
What are Sam Altman’s counterclaims?
Sam asserted counterclaims for abuse of process and defamation. According to the court’s order, he alleged that Annie’s lawsuit and public statements were false and were partly intended to pressure him and the family over financial support and other assistance.
The judge’s decision to let those counterclaims survive a motion to dismiss means only that Sam had pleaded claims sufficiently to continue at that stage. It does not mean he proved defamation or abuse of process.
Did the court clear Sam Altman or confirm Annie’s allegations?
No. The March 2026 order did neither.
A motion to dismiss tests whether the complaint states legally viable claims and, for many purposes, accepts well-pleaded factual allegations as true while conducting that legal analysis. It is not an evidentiary hearing. The order therefore cannot accurately be described as either validating or disproving Annie’s allegations.

The March 20, 2026 order set April 3, 2026 as the deadline for Annie to file an amended complaint. The materials available for this article do not independently establish whether she filed that amendment, whether the statutory claims survived later motions, or whether the case was settled, dismissed in full, or proceeded into discovery or trial.
Accordingly, the case should not be described as ongoing, settled, headed for trial, or fully dismissed without a later docket entry confirming that status.
