Sam Altman's Sister Asks Judge To Dismiss His Defamation Suit, Stands By Abuse Allegations

Ann Altman, the sister of OpenAI CEO Sam Altman, has asked a judge to dismiss a defamation counterclaim he brought against her, and she reiterated in court documents that her allegations of childhood sexual abuse are true, according to filings reviewed by TMZ.

Legal Fight Over Allegations and Reputation

In the filing, Ann disputes Sam Altman's assertion that she defamed him and objects to his description of her as "mentally ill." She says Sam "slanderously characterized her" in his counterclaim and on social media in what she describes as an effort to "silence her."

Ann says she was diagnosed with post-traumatic stress disorder (PTSD) that she attributes to the alleged abuse.

Financial Support And A Declined Offer

Ann denies receiving ongoing monthly support from Sam but acknowledges that he provided financial help in prior years for bills and other expenses. She also says Sam once offered to buy her a home, an offer she declined because of the terms attached to the proposed "gift."

Social Media Posts

Ann admits she posted about being abused on social media but says she never named Sam. According to her filing, her posts described being "touched by older siblings," and she asked the court to dismiss Sam's counterclaims against her.

Allegations, Denials And Counterclaims

Earlier reports say Ann alleges the abuse occurred from about 1997 to 2006, when she says the behavior began at age three and Sam was 12. Sam Altman has emphatically denied the allegations and said other family members have publicly supported him during the dispute.

Sam filed a countersuit for defamation seeking a nominal $1 in damages, saying he primarily seeks a legal finding that the allegations are false.

Note: These are developments reported in court filings and media accounts. The allegations remain disputed and have not been proven in court.
