The details
US District Judge Zachary Bluestone dismissed the civil lawsuit filed by Ann Altman against her brother, OpenAI chief executive Sam Altman, on Tuesday. The judge did not rule on the merits of the abuse claims. Instead, the dismissal was based on Ann Altman’s refusal to appear for an independent medical examination. The court had warned her that skipping this examination would lead to the case being dismissed.
Ann Altman filed the lawsuit in January 2025, alleging that Sam Altman sexually abused her between 1997 and 2006 at the family home in Missouri. She claimed the abuse began when she was three years old and he was twelve, with the last alleged instance occurring when he was an adult. Sam Altman, now 41, has denied these claims.
The case had previously been revised. In March, Judge Bluestone ruled that Ann Altman’s original sexual assault and battery claims had expired. However, he allowed her to refile under a Missouri childhood sexual abuse law. She filed the amended suit, which was dismissed on Tuesday. The dismissal was with prejudice, meaning the case cannot be refiled in that court.
The context
Sam Altman, his mother, and two younger brothers issued a joint statement after the initial lawsuit was filed. They called the allegations entirely untrue. The statement claimed that Ann Altman has mental health challenges, refuses conventional treatment, and lashes out at family members trying to help. Judge Bluestone also approved Sam Altman’s request to withdraw a defamation counterclaim he had made against his sister.
Ann Altman’s former lawyer, Santos Perez, withdrew from the case in October. He stated that he was no longer authorized to comment but continued to believe in Ann Altman. The judge denied Sam Altman’s request for attorney fees and costs associated with the legal proceedings.
