The law targets major AI operators including OpenAI and Anthropic. It follows a pattern of state-level AI regulation: California's perception-based chatbot rules, Oregon's SB 1546 enacted in March 2026, and Washington's companion statute HB 1170 requiring AI watermarks on altered media for large firms. Legislative activity began in early 2026 with committee reviews in January.
Washington's statute is the first to impose prescriptive timing requirements for disclosures, design mandates prohibiting human impersonation, and minor-specific prohibitions on manipulative design—coupled with a private right of action. The combination positions the law as a template for other states. It addresses documented risks of AI deception and youth mental health harms amid accelerating state regulation in 2026.
