ChatGPT, Grok, and Claude Suffer Simultaneous Outages

OpenAI's ChatGPT, xAI's Grok, and Anthropic's Claude all went dark around 11AM ET on September 3, 2026 — the first known instance of all three major AI chatbot providers failing in the same narrow window. ChatGPT errors spanned conversations, logins, voice mode, search, and image generation. No root cause had been determined at the time of reporting. Each provider stated it was working on a fix.
