Anthropic’s Claude AI chatbot suffered a partial outage on February 25, 2026, with over 4,700 users reporting issues via DownDetector before service stabilized within 90 minutes. The disruption primarily affected Claude Chat (45% of reports), Claude Code (25%), and the desktop app (19%), which failed to launch for some users until a fix was deployed. Anthropic confirmed "elevated errors" persisted in its latest models, Claude Sonnet 4.6 and Opus 4.6, despite the partial resolution by 1:45 p.m. EST. This marks the third outage in two months, following a January incident and a February disruption tied to the Sonnet 4.6 release, which triggered a global software stock selloff. Anthropic’s valuation surged to $380 billion after a $30 billion funding round, up from $61.5 billion in March 2025.
