OpenAI chief executive Sam Altman’s sister, Ann Altman, has filed a lawsuit alleging that he regularly sexually abused her between 1997 and 2006.
The lawsuit, which was filed on 6 January in a US District Court in the Eastern District of Missouri, alleges that the abuse started when she was three and Mr Altman was 12.
In a joint statement on X, with his mother and two brothers, Mr Altman denied the allegations, saying “all of these claims are utterly untrue.”
“Caring for a family member who faces mental health challenges is incredibly difficult,” the statement added.
