What's the story

Annie Altman, the sister of OpenAI CEO Sam Altman, has amended her civil lawsuit against him, alleging sexual abuse dating back to their childhood. The updated complaint was filed on Wednesday in a federal court in St. Louis. The case stems from incidents that allegedly took place between 1997 and 2006 at their family home in Clayton, Missouri.

Abuse claims

Abuse started when Annie was 3 years old, alleges lawsuit

Annie has accused her brother of sexually abusing and raping her multiple times during the said period. She claims that the abuse started when she was three years old and Sam was 12. The allegations were initially filed as a standalone civil lawsuit but were amended after a judge allowed Annie to pursue her case under Missouri's child sexual abuse statute.

Legal proceedings

Missouri law allows long-ago abuse victims to sue

On March 20, US District Judge Zachary Bluestone in St. Louis ruled that Annie's standalone sexual assault and sexual battery claims had expired in 2008. However, he also noted that the Missouri statute allows some accusers to sue over alleged abuse from long ago. This ruling opened the door for Annie to pursue her allegations of childhood sexual abuse against Sam under this specific law.

Defamation counter

Sam countersues sister for defamation

Sam has denied Annie's allegations and countersued Annie for defamation. The countersuit was filed over social media posts made by Annie that referred to the alleged abuse. These included a video in which she claimed "an almost tech billionaire" had molested her. The legal battle continues as both parties stand firm on their respective positions.

Family dynamics

Family dynamics amid legal battle

The Altman family has publicly stated that Annie has been struggling with mental health issues. In a court filing, Sam claimed that his family has been supporting her financially but argued that her lawsuit is an act of extortion. The complex family dynamics add another layer to the ongoing legal dispute between the two siblings over these serious allegations of childhood sexual abuse.
