US Court Dismisses Annie Altman’s Sexual Abuse Lawsuit Against Sam Altman

OpenAI CEO Sam Altman has won the dismissal of a sexual abuse lawsuit filed by his sister, Annie Altman, in the United States. US District Judge Zachary Bluestone dismissed the case on Tuesday, October 20, 2026, after Annie reportedly failed to attend an independent medical examination despite repeated opportunities and warnings. Annie had accused her brother of sexually abusing her during her childhood. Sam Altman has denied all the allegations.

The judge said Annie failed to follow important legal requirements, which prevented the case from moving forward. According to the court’s order, she missed the medical examination on three occasions. The judge had reportedly warned her that failing to attend could lead to the dismissal of the case. The court eventually dismissed the lawsuit with prejudice, meaning it cannot be filed again in the same court.

Annie Altman filed the lawsuit against her brother on January 6, 2025, in a federal court in Missouri. She alleged that the abuse took place between 1997 and 2006 at their family home in Clayton, Missouri. According to her claims, the alleged abuse began when she was three years old and Sam was 12. She also claimed that the incidents continued for several years. These allegations have been denied by Sam Altman.

What Did Sam Altman and His Family Say?

When the lawsuit was filed in 2025, Sam Altman, his mother and his two brothers released a joint statement denying the allegations. The family reportedly said the claims were untrue and expressed concern about Annie’s well-being. They also said they had supported her financially over the years, including help with rent, bills and medical care.

Sam Altman has said that his sister began making allegations against him on social media after the family refused her requests for additional financial support. The family also disputed her claims. The court’s latest decision was based on Annie’s failure to meet legal requirements, including attending the medical examination. The dismissal ended the case in that court, while Sam Altman continued to deny the allegations made against him.
