Major Risk Factors Disclosed

Microsoft Dependency: OpenAI warned that termination or modification of its Microsoft partnership could "adversely affect" its business and financial condition.

Supply Chain: Potential disruptions from NVIDIA if regional conflicts affect Taiwan; reliance on chip suppliers amid global shortages.

Legal Challenges: At least 14 lawsuits from ChatGPT users alleging mental health harm and suicide-related deaths; ongoing litigation with Elon Musk's xAI (three separate lawsuits); copyright and IP disputes.
