Trader consensus on 5-7 days of Claude downtime in September stems from Anthropic’s official status page documenting multiple confirmed incidents with elevated errors or partial outages across claude.ai, the API, Claude Code, and Cowork. Verified disruptions occurred on at least six dates—September 3, 11, 15, 16, 22, and 29—each lasting 35 minutes to roughly 1.5 hours, with the final event on the 29th resolved within an hour after mitigation. These align with historical patterns of recurring infrastructure strain during periods of model updates and high usage. While strong market-implied odds reflect this tally of distinct days, outcomes could shift only if additional unreported micro-outages or reclassifications of minor degraded performance push the count outside the 5-7 range.
