(CNA Reporter Ji Jin-ling, New York, 15th Comprehensive Foreign Report) Artificial intelligence company OpenAI CEO Sam Altman was accused by his sister Annie Altman of sexually assaulting her more than 20 years ago, and she is demanding punitive damages in a civil lawsuit. Altman denied the allegations and filed a defamation countersuit.
According to Reuters, based on documents submitted to the federal court in St. Louis, Missouri late today, Altman stated that his sister's lawsuit regarding his behavior as a minor does not warrant punitive damages. He asked the court to dismiss Annie's lawsuit entirely.
Annie's lawyer did not immediately respond to Reuters' request for comment outside of business hours.
Annie alleged that her brother sexually assaulted and raped her at their suburban home in Clayton, Missouri between 1997 and 2006, when she was just 3 years old and Altman was 12. Annie stated that even after reaching adulthood, Altman still committed the "last few sexual assaults and rapes" against her.
Altman is currently 40 years old. The Altman family stated that Annie has mental health struggles and has also received financial assistance in the past.
Altman claimed that Annie only began accusing him of sexual assault on social media after family members rejected her "increasing financial" extortion.
This lawsuit was filed in January 2025.
Annie made posts on social media, including a video alleging that a "tech giant soon to be a billionaire" had sexually assaulted her. In response, Altman filed a defamation countersuit against Annie.
Altman is only seeking a symbolic compensation of $1. He stated he "does not want to put his sister in a difficult financial situation" but hopes to prove through the verdict that his sister's allegations are false.
Since the launch of the chatbot ChatGPT in 2022, Altman has become a representative figure of the artificial intelligence (AI) wave. (Translation: Ji Jin-ling) 1150416
