  1. Correction

    Colorado: AI disclosure rule replaced

    Our table listed Colorado’s SB 24-205 duty to tell consumers they are interacting with an AI system, with a June 30, 2026 start date marked unconfirmed. SB 26-189, signed May 14, 2026, repealed and re-enacted that part of the law to cover only automated decision-making technology used in consequential decisions, so the general duty no longer applies. The Colorado row now covers HB 26-1263, signed May 29, 2026, which requires conversational AI services to say they are AI from January 1, 2027 and excludes customer service software.
