Three missed appointments led to dismissal:
Annie Altman failed to appear for an independent medical examination on three separate occasions, despite warnings from the judge. -
The ruling bars her from refiling the same claims:
The judge dismissed the case with prejudice, preventing Annie from bringing the same claims again, but did not determine whether the abuse allegations were true. -
The case was first filed in 2025:
Sam Altman’s sister alleges that the abuse occurred between 1997 and 2006—claims that the OpenAI CEO has consistently denied.
Sam Altman, CEO of OpenAI, the company behind ChatGPT, won the dismissal of a civil lawsuit filed by his sister, Annie Altman, on Tuesday, Oct. 20. She had accused him of repeated sexual abuse more than two decades ago — allegations he has consistently denied.
The ruling was issued by U.S. District Judge Zachary Bluestone in St. Louis, Missouri. However, the dismissal does not mean the court determined whether the allegations were true.
What Led to the Case Being Dismissed?
According to the judge, Annie Altman refused to appear for an independent medical examination, part of the discovery process, despite repeated warnings that failing to do so would result in dismissal. The court also offered special accommodations and set a final deadline of October 16.
Three No-Shows and a Final Ruling
In his memorandum, Bluestone was direct: Annie failed to appear for the examination on three separate occasions. “It is clear that Annie has sought to intentionally delay this case,” he wrote. “The Court has run out of options and, thus, dismisses her claims with prejudice.”
In practical terms, the ruling bars Annie from refiling the same lawsuit on the same grounds.
The Allegations Against Sam Altman
Annie filed the lawsuit in January 2025 in federal court in St. Louis. She alleged that her brother had groomed, manipulated, and sexually abused her at the family home in Clayton, a suburb of St. Louis, Missouri.
According to the complaint, the alleged abuse occurred between 1997 and 2006, beginning when she was 3 years old and he was 12. She alleged that the abuse continued into the period when Sam was an adult. He is now 41.
In the lawsuit, Annie sought more than $75,000 in damages, plus punitive damages, alleging physical and emotional harm. Sam, in turn, sought nominal damages of $1 in a separate defamation lawsuit against his sister.
A Legal Battle With Several Turns
In March 2026, the case was dismissed because it had been filed after Missouri’s statute of limitations had expired. In April, however, the judge allowed Annie to refile the lawsuit under a different law specific to childhood sexual abuse cases. Shortly afterward, her attorneys withdrew from the case, and the proceedings stalled until she found new legal representation.
Attorneys Remain Silent
Laura Politi, Annie’s current attorney, did not immediately respond to requests for comment. Santos Perez, who previously represented Annie in the case, said: “I am no longer authorized to comment on this case, but I continue to believe in Annie.”
What the Altman Family Says
Sam Altman did not comment on the ruling, but he had previously described the allegations as “completely untrue.” In a joint statement with his mother and siblings, he said Annie faced mental health challenges, had refused conventional treatment, and was “lashing out” at family members who had supported her financially for years.
“We ask for understanding and compassion as we continue to support Annie in the best way we can,” the family wrote.
