Anthropic published its annual 2026 Usage Policy update on October 8, 2026, consolidating its rules against deceptive campaigns, adding a prohibition on abusive behavior toward its models, and clarifying weapons, surveillance, and high-risk use requirements. The updated policy takes effect November 12, 2026. Anthropic said most of the changes are intended to clarify existing rules. The company said the revision responds to a year in which Claude took on longer and more independent work, incorporates customer feedback, and draws on misuse patterns in influence operations, weapons development, and surveillance documented in its September 2026 threat intelligence report.

It is organized into Universal Usage Standards applying to all users, High-Risk Use Case Requirements for specific consumer-facing uses with elevated risk of harm, and Additional Use Case Guidelines covering consumer-facing chatbots, products serving minors, agentic use, and Model Context Protocol servers.
