Anthropic Updates Claude Usage Policy, Effective November 12, 2026

Anthropic has published a 2026 update to its Usage Policy, taking effect November 12, mostly to clarify existing rules for longer, more autonomous Claude work.

The changes consolidate deceptive-campaign prohibitions into a new section, narrow the elections rules to voter deception and disruption, and explicitly ban weapons-related software and surveillance tools.

Requirements for high-risk uses and for models connected to autonomous physical hardware were also tightened.
