Claude usage rules change on November 12

Anthropic's updated Usage Policy for Claude takes effect on November 12, 2026, according to Anthropic's update post of October 8, 2026, and the effective date on the Usage Policy page. The update adds a new section on deceptive campaigns and artificial activity, and sets controls for equipment that Claude drives. The policy covers everyone who uses Claude, from Claude.ai and Claude Code users to businesses on the API.

Who does the Usage Policy apply to?

The policy page lists its audience as all users. Anthropic says it "applies to anyone who submits inputs to Anthropic’s products or services", including individual app users, "developers and businesses using our API and developer platforms", customers reaching Claude through cloud providers and authorized resellers, and end users of products built on Claude. So the rules below bind API business customers as well as people using Claude's apps. For background on the company, see our Anthropic entity page.

What is the new deceptive-campaigns section?

Anthropic says it gathered rules that had been scattered across the policy into a new section, "Do Not Engage in Deceptive Campaigns or Artificial Activity", which applies to deceptive activity "whether political or commercial". The policy text bans fake personas, accounts and outlets, giving "sockpuppets, astroturfing, fake reviews, or bots that claim to be human" as examples. It also bans concealing who sponsors messaging meant to influence public opinion, officials or other decision-makers, and running networks that hide a common source. Seeding the sources that search engines or AI systems draw answers from with content that misrepresents its origin, authorship or independence is banned too. So is building tools for such campaigns or selling any of them as a service.

What are the new rules for physical equipment?

When Claude's outputs drive hardware that takes autonomous physical actions that might cause injury, "a qualified operator must be able to observe the equipment and stop it if needed", and the equipment must hold a safe state if Claude is disconnected, Anthropic says. The policy text applies these requirements "when outputs of our products and services are acted upon by hardware without human approval". That covers hardware that can move in shared space, apply injurious force, control hazardous energy or materials, act on the body, control safety systems or run industrial processes. Operating limits for such equipment "must be enforced by the equipment or a controller independent of model output". Consumer and household devices working within the manufacturer's built-in safety limits, where the worst outcome is discomfort or inconvenience, are excluded.

What does the policy say about reselling Claude?

The Usage Policy bans users from reselling, proxying or otherwise providing access to Claude "through unauthorized means, including services that route requests through consumer subscriptions or misrepresent the product or client being used". This line sits in the policy's "Do Not Abuse Our Platform" section; Anthropic's update post does not mention it, and we have not checked whether it is new in this version.

What this means for your business

Our analysis: because the policy applies to every Claude user, including API customers, a small business should check three things before November 12, 2026. First, stop any Claude-generated fake reviews, sponsored messaging that hides who paid for it, or bots that pose as humans. Second, if you reach Claude through a third-party tool, check that it does not route requests through someone's consumer subscription, which the policy bans; our Claude API guide for business automation covers the direct API route. Third, if Claude drives any machinery, make sure a person can stop it and that limits are enforced independently of the model.
