ChatGPT, Grok, and Claude Experience Simultaneous Outages
On September 3, 2026, users reported outages across three major AI chatbots: OpenAI’s ChatGPT, xAI’s Grok, and Anthropic’s Claude. The issues began around the same time—approximately 10 AM to 11 AM ET—with error messages disrupting service for many users. OpenAI noted 'elevated errors' affecting both ChatGPT and Codex, while Anthropic reported outages across several models before narrowing it down to Opus 4.8 and Opus 5. Grok also confirmed an outage on its app and website but did not provide further details. The cause of the simultaneous issues remains unclear, though each company is working independently to resolve them. OpenAI stated that a mitigation strategy had been applied, while Anthropic continued efforts toward a fix. The Verge reached out for comment from all three companies but received no immediate response.
