Anthropic to Implement Invisible Watermarks on Claude Text by August 2026

Anthropic has announced plans to introduce machine-readable watermarks on text generated by its Claude models starting August 2, 2026. This initiative aligns with the transparency requirements set forth in Article 50 of the EU AI Act, as the company has also signed the European Union’s Code of Practice for AI-generated content.
The implementation of these watermarks is significant as it aims to enhance the traceability of AI-generated text, providing a method for users and organizations to verify whether content was produced by Claude. The watermarks will be invisible during normal reading and will persist even when text is copied and pasted, ensuring that the marking is applied at the model level across various Claude products.
Looking ahead, Anthropic plans to publish technical details for detecting these watermarks, which will assist users and third parties in verifying the authenticity of Claude-generated content. While older Claude models will not receive immediate updates, Anthropic is working on integrating marking capabilities during the transition period of the EU AI Act. No further timeline was disclosed at the time of publication.
