Anthropic's Claude Rolls Out Global AI Watermarking to Meet EU Rules

Anthropic says Claude will begin watermarking AI-generated text and digitally signed provenance for files to comply with the EU AI Act. The feature will launch with EU-ready models from Aug 2, 2026 and will be available worldwide on Claude’s platform, though some platforms may not support watermarking. Watermarks for text are embedded in the content; files use provenance metadata and images will leverage the C2PA standard. Existing models will be updated later; watermarking isn’t foolproof and could be bypassed by heavy paraphrasing or metadata stripping.
