Annie Altman, sister of OpenAI CEO Sam Altman, has filed an amended complaint in a St. Louis federal court after a judge dismissed her initial lawsuit alleging sexual abuse. The amended complaint, submitted on Wednesday, seeks to proceed under Missouri's Childhood Sexual Abuse statute, which allows some accusers to sue over historical abuse.
U.S. District Judge Zachary Bluestone had ruled last month that Annie Altman could not pursue claims of sexual assault and battery for alleged abuse between 1997 and 2006, as those claims expired in 2008. However, he permitted her to refile under the state's childhood abuse law.
Annie Altman alleges her brother sexually abused and raped her repeatedly from 1997 to 2006 at the family home in Clayton, Missouri, starting when she was three and he was 12. Sam Altman, now 40, has denied the allegations through his legal team, which did not immediately respond to requests for comment on the amended complaint.
The case also involves a defamation counterclaim from Sam Altman, stemming from social media posts between 2021 and 2024 where Annie Altman referenced abuse without naming him. The Altman family has cited her mental health challenges, with Sam Altman stating in court filings that the family has supported her financially but views the lawsuit as extortion.
Sam Altman, co-founder of OpenAI and a prominent figure in the AI industry following ChatGPT's 2022 launch, has a net worth estimated at $3.3 billion by Forbes magazine.
