On September 3, 2026, outages occurred in services provided by Anthropic, including Claude, Claude Code, and their API. These outages were reported to have occurred around the same time as service disruptions affecting OpenAI's ChatGPT and xAI's Grok. While services from each company have since been restored, this incident suggests the risk of multiple AI services becoming unavailable simultaneously as AI becomes increasingly integrated into business processes.
