According to Odaily, Ann Altman, the sister of OpenAI CEO Sam Altman, has filed a lawsuit accusing her brother of sexual abuse from 1997 to 2006. The case was lodged in the U.S. District Court for the Eastern District of Missouri, alleging that the abuse occurred at their home in Clayton, Missouri, beginning when Ann was 3 years old and Sam was 12. The lawsuit claims the abuse happened several times a week. As a result of the alleged incidents, Ann Altman reportedly suffers from severe emotional distress, mental anguish, and depression, which are expected to persist. Although Ann has previously made public accusations against her brother on platforms like X, this marks her first legal action against him. The lawsuit seeks a jury trial and damages exceeding $75,000. In a joint statement with their mother and brother on X, Sam Altman has denied the allegations.
