Sam Altman, the CEO of OpenAI, has been accused of childhood sexual abuse by his estranged sister, Ann Altman, in a lawsuit filed in Missouri. Ann claims the abuse occurred in the 1990s and 2000s, resulting in severe emotional distress and PTSD. The Altman family has publicly denied the allegations, claiming they are untrue and stemming from Ann’s mental health challenges. The lawsuit seeks damages exceeding $75,000. This is not the first instance of allegations from Ann, who has previously claimed abuse by her siblings on social media.
