Sam Altman sister's sex abuse suit tossed by US judge

A federal judge in Missouri has thrown out a lawsuit brought by Ann Altman against her brother, Sam Altman, the chief executive of OpenAI. The ruling, issued Tuesday, ends — at least for now — litigation that had accused the tech leader of sexual abuse spanning roughly a decade.

Judge Cites Failure to Appear for Medical Exam

In her January 2025 filing in St. Louis federal court, Ann Altman alleged that her brother sexually abused and raped her between 1997 and 2006. The alleged conduct took place at the family's home in suburban Clayton, Missouri, according to the suit, and began when she was three years old and he was 12. She claimed the final instances occurred after Sam Altman had reached adulthood. He is now 41. US district judge Zachary Bluestone, in dismissing the case, noted that Ann Altman had declined to undergo an independent medical examination. The judge had warned that skipping the exam would lead to the case being thrown out. Sam Altman has denied the allegations. The Altman family has stated that Ann Altman faces mental health challenges and has received financial assistance from them. According to Sam Altman, his sister started leveling accusations of sexual abuse against him on social media only after the family turned down her requests for additional money.

Legal Representation Shifts

Laura Politi, an attorney for Ann Altman, did not immediately respond to a request for comment. Santos Perez, who had represented Ann Altman earlier in the proceedings but withdrew from the case this month, issued a statement: "I am no longer authorized to comment on this case but I continue to believe in Annie." Lawyers representing Sam Altman also did not immediately respond to a request for comment.
