OpenAI's legal woes are piling up. Here are the toughest battles facing Sam Altman and ChatGPT. (www.businessinsider.com)

OpenAI and CEO Sam Altman are facing a widening slate of lawsuits—ranging from cofounder-turned-rival Elon Musk’s claims that OpenAI illegally converted from a nonprofit (and that it poached xAI staff and trade secrets) to major publishers and authors suing over copyright for scraping and reproducing news and books, to wrongful-death and mental-harm suits blaming ChatGPT’s responses, plus a trademark spat with Cameo. Business Insider’s roundup highlights the most consequential cases: Musk’s challenge to OpenAI’s Microsoft licensing deal (a Phase I trial is set), consolidated publisher/author copyright suits that a judge recently declined to dismiss, multiple wrongful-death filings tied to an older GPT-4o model, and a temporary injunction over use of the word “cameo.” These cases matter beyond damages: rulings could redefine fair use for training data, force companies to disclose training datasets and model behavior through discovery, and reshape how LLMs are built, licensed, and moderated. A finding against OpenAI could drive industry-wide changes—stricter sourcing/licensing of corpora, new model-audit requirements, stronger age verification and crisis-response safeguards, and limits on exclusive partnerships. Technically, litigation centers on whether scraped content yields verbatim outputs (Judge Stein found prima facie similarity), so outcomes will influence training pipelines, prompt controls, and legal risk management for all AI developers.
