OpenAI CEO Sam Altman has publicly denied allegations of sexual assault made by his estranged sister, Annie Altman, in a lawsuit filed on January 6, 2025. The lawsuit claims that Sam assaulted her over a nine-year period, echoing previous social media accusations. The Altman family asserts that these claims are false and express concern for Annie's mental health, citing her unstable personal life and past challenges. They have attempted to support her financially but claim she continues to make unfounded demands for money and has evolved her allegations over time.
