What the Evidence Shows
Annie Altman has alleged in civil court filings that her brother, Sam Altman, sexually abused and raped her during their childhood and adolescence. Reporting places the alleged conduct at the family home in Clayton, Missouri, and describes claims spanning several years. These reports establish that the accusation and lawsuit exist, not that the allegations have been proven.reuters.comreuters.comSam Altman's sister amends lawsuit accusing OpenAI CEO of sexual abuse

Later reporting in 2026 indicates that the litigation continued, including an amended complaint and disputes over damages.
