Lawsuits allege OpenAI hid violent ChatGPT users to shield IPO and CEO

California families’ lawsuits accuse OpenAI of ignoring internal safety warnings about a ChatGPT user linked to a Canadian school shooting, allegedly to protect CEO Sam Altman and the company’s IPO. The account was deactivated but could be rejoined with a new email, a move whistleblowers say concealed violent intent and delayed reporting to police. OpenAI apologized and denies wrongdoing, while the families seek damages and more suits are expected.
