Ann Altman has previously made similar accusations against her brother on social media platforms.
In the court documents filed in Missouri, Ann Altman’s attorneys assert that she has suffered mental health challenges due to the alleged abuse.
Ann also accused Altman and the entire family of withholding their father’s 401k funds, hacking her Wi-Fi, and “shadowbanning” her on platforms like ChatGPT and Twitter.
The case, titled Altman v. Altman, is being heard in the US District Court for the Eastern District of Missouri in St. Louis (Case No. 4:25-cv-00017).
| Altman’s current net worth is $1.1 billion according to our estimates. Although OpenAI was recently valued at $157 billion, Altman presently has no equity in the company. His wealth stems from stakes in several companies including Reddit, payments platform Stripe and nuclear fusion firm Helion. The ChatGPT maker is in the process of converting to a for-profit entity and Altman is reportedly in line to receive a 7% stake once that happens. |
