Judge Dismisses Sam Altman Sexual Abuse Lawsuit, But Sister Can Refile

A federal judge has dismissed a sexual abuse lawsuit filed against OpenAI CEO Sam Altman by his sister Annie Altman, ruling that the claims were too old to pursue under current law. However, U.S. District Judge Zachary Bluestone left the door open for Annie Altman to refile under Missouri's Childhood Sexual Abuse statute, giving her legal team a path forward.

The lawsuit, filed in January 2025, accused Sam Altman of sexually abusing Annie Altman at the family's home in Clayton, Missouri, starting in 1997 when she was just three years old and continuing until 2006. Judge Bluestone ruled in a St. Louis federal court that the sexual assault and sexual battery claims had legally expired in 2008, making them no longer viable under those specific legal theories.

In a significant counter-development, the judge also ruled that Sam Altman may pursue a defamation counterclaim against his sister. Between 2021 and 2024, Annie Altman made a series of posts on social media platforms including X and TikTok, referencing abuse by "older siblings" and an "almost tech billionaire," without directly naming her brother. The court found these statements could reasonably be interpreted as pointing to Sam Altman, potentially meeting the legal threshold for a defamation claim if actual malice can be proven.

Sam Altman, now 40 and valued at an estimated $3.4 billion according to Forbes, has denied all allegations. His family has characterized Annie Altman as facing mental health challenges and described the lawsuit as an attempt at extortion, noting that they provide her with ongoing monthly financial support.

Annie Altman's attorney confirmed she will file an amended complaint and continue building her case. Meanwhile, Sam Altman remains at the center of the global AI conversation as co-founder of OpenAI, the company behind ChatGPT, which launched in 2022 and reshaped the technology landscape.
