Sam Altman's Sister Files Amended Lawsuit — Judge Allows Childhood Sexual Abuse Claims to Proceed Under Missouri Law

U.S. News·medium signal

Annie Altman filed an amended federal lawsuit on April 1, 2026 in St. Louis alleging Sam Altman sexually abused her between 1997 and 2006 starting when she was three. A federal judge dismissed the original statute-of-limitations claims but allowed the case to proceed under Missouri's Childhood Sexual Abuse statute. Altman denies all allegations and is countersuing for defamation. The case adds to the convergence of credibility attacks on Altman alongside the New Yorker investigation and CFO rift.
