US judge dismisses sexual abuse lawsuit filed by Sam Altman’s sister
A US district judge in St Louis dismissed a lawsuit filed by OpenAI CEO Sam Altman's sister alleging childhood sexual abuse on Tuesday.

Reason for case dismissal
Judge Zachary Bluestone ended the legal action because the plaintiff refused to attend an independent medical examination. The court noted that previous warnings stated failure to comply would lead to dismissal. This procedural issue resulted in the case being thrown out with prejudice.
Timeline of the claims
Ann Altman accused her brother of abuse occurring between 1997 and 2006 at their family home in Missouri. She stated that the final incidents happened when Sam Altman was an adult. The lawsuit was originally brought to federal court in January 2025.
Responses from the parties
Sam Altman denied the allegations and his family called the claims untrue. A lawyer who previously represented Ann Altman withdrew from the case this month. Lawyers for both sides did not immediately respond to requests for comment.
