Sam Altman’s sister amends lawsuit accusing OpenAI CEO of sexual abuse

Sam Altman’s sister amended her civil lawsuit accusing the OpenAI ​chief executive of sexually abusing her more than ‌two decades ago, after the judge ​said she could try pursuing her ⁠case under Missouri’s child sexual abuse statute.

On March 20, U.S. District Judge ​Zachary Bluestone in St. Louis said the woman’s standalone sexual assault and ⁠sexual battery claims expired in 2008, but the Missouri statute let some accusers sue over alleged ‌abuse from long ago.

Sam Altman’s defamation claim stemmed from social media posts by his sister that referred to alleged abuse, including a video that said “an almost tech billionaire” molested her.

The Altman family has said ‌their family member has mental health challenges. In a court ​filing, Sam Altman said his family has been helping her, including financially, ⁠but that her lawsuit amounted to extortion. Sam Altman co-founded ⁠OpenAI.

He became a face of the artificial intelligence boom after the ‌AI chatbot ChatGPT was released in 2022. Forbes magazine says Sam Altman is worth $3.3 ​billion.
