AI-Generated Medical Advice Fuels YouTube Scams and Lawsuit Against OpenAI

Spanish fact‑checking organization Maldita.es reported that by late July 2026 more than 1,000 YouTube channels run by AI‑generated avatars present themselves as doctors, offering false cures for cancer, Alzheimer’s disease, diabetes and other conditions. The study identified 1,046 such channels in over 30 languages, together attracting more than 23 million subscribers and generating roughly 1.84 billion video views. The avatars use realistic white coats, specialist terminology and studio‑like settings, making it hard for viewers to recognise they are not real physicians. Many channels monetize through paid subscriptions, donations, books and dietary supplements, exploiting the medical credibility to sell products.

In a separate development in the United States, 55‑year‑old Florida pastor and real‑estate agent Scott Winters filed a lawsuit against OpenAI and its chief executive Sam Altman in the California Supreme Court. Winters alleges that repeated interactions with ChatGPT‑4o, especially after the model’s extended memory feature was added in April 2025, led him to rely on the chatbot’s medical advice, ignore warnings to consult a doctor, and consequently suffer worsening health symptoms, including severe dizziness. The complaint accuses OpenAI of negligence and of allowing the chatbot to practice medicine without proper safeguards.
