US Judge Dismisses Ann Altman's Abuse Lawsuit Against Sam Altman

A federal judge in Missouri dismissed a sexual abuse lawsuit filed by Ann Altman against her brother, OpenAI CEO Sam Altman, after she failed to attend a required independent medical examination. US District Judge Zachary Bluestone issued the dismissal on Tuesday, October 20, 2026, citing her failure to comply with the examination requirement despite warnings that the case could be thrown out. Ann Altman filed the lawsuit in federal court in St.

Louis in January 2025. She accused her brother of sexually abusing and raping her between 1997 and 2006 at their family home in Clayton, a suburb of St. Louis, according to reporting by The Guardian.

Sam Altman has denied the allegations. The lawsuit sought unspecified damages related to alleged post-traumatic stress disorder, according to court documents described by Yahoo's coverage of the case. The dismissal followed a separate dispute over the publication of confidential deposition materials, which Sam Altman had asked the court to restrict.

Ann Altman's former attorney, Santos Perez, who withdrew from the case in October, said he could no longer comment on the proceedings but continued to support his former client.

"I am no longer authorized to comment on this case but I continue to believe in Annie." Santos Perez, a former lawyer for Ann Altman. Laura Politi, who represents Ann Altman, did not immediately respond to The Guardian's request for comment following the dismissal. Lawyers representing Sam Altman also did not immediately respond to requests for comment.

In a separate court filing reported by Yahoo on October 19, Sam Altman accused his sister of posting portions of her deposition on X, TikTok and other online platforms. He asked the court to require her to confirm within three days that she had destroyed confidential deposition videos and transcripts. Sam Altman argued in the filing that Ann Altman and her lawyers had incorrectly maintained that she could publish the complete deposition video. He also questioned her motives for pursuing the lawsuit, alleging that the case was being used to generate material for her social media accounts and podcasts.

"There is serious reasons to believe that [Ann's] true purpose in bringing this lawsuit was not to litigate her claims in good faith but rather to create discovery that she can use to drive traffic to her social media accounts and podcasts." Sam Altman, in a court filing described by Yahoo. The Altman family has said Ann Altman has mental health challenges and has received financial support from relatives.

Sam Altman has also alleged that she began accusing him of sexual abuse on social media after the family rejected her requests for additional money. According to Yahoo's report, Sam Altman also filed a countersuit seeking $1 and received support from several family members in court. The allegations against him remain disputed, and the judge's dismissal was based on Ann Altman's failure to attend the required medical examination.
