Altman Seeks to Dismiss Punitive Damages in Abuse Lawsuit

Sam Altman asked a federal judge to remove punitive-damages claims from the lawsuit filed by his sister, a move that would sharply narrow the financial stakes in a case built around childhood sexual-abuse allegations and a long family rupture. In a filing Wednesday night in St. Louis federal court, Altman argued that Missouri’s child sexual abuse statute does not authorize punitive damages and limits recovery to damages for injury or illness.

The request matters because punitive damages are designed to punish conduct beyond compensating a plaintiff for harm. If the court grants Altman’s bid, Annie Altman could still pursue compensatory damages under the Missouri statute, but the case would lose a more severe category of punishment and leverage. Altman also argued that punitive damages are unavailable for conduct he allegedly committed as a child. He renewed his request to dismiss the case entirely and continued to deny the accusations.

Annie Altman has accused her brother of sexually abusing and raping her between 1997 and 2006 at the family home in suburban Clayton, Missouri, starting when she was 3 and he was 12. She has said the last acts of abuse occurred when Sam Altman was an adult. The lawsuit began in January 2025, then was dismissed on timing grounds in March 2026 before the court allowed her to refile under a different Missouri law.

The case has unfolded as part of a larger public clash around one of the most visible executives in artificial intelligence. Altman is the chief executive of OpenAI, the company behind ChatGPT, and he is also facing a separate defamation countersuit in which he seeks $1 and says he does not want to financially harm his sister but wants a verdict saying her statements are false. The family has said Annie Altman has mental health challenges and had received financial support.

Altman’s legal exposure is not limited to the family case. He is also scheduled to face an April 27 trial in Elon Musk’s lawsuit against OpenAI, which adds another layer of pressure on the company and its top executive. As the abuse lawsuit moves ahead in the U.S. District Court for the Eastern District of Missouri, the fight over punitive damages will help determine whether the case remains focused on compensation alone or carries the added possibility of punishment.
