Connecticut Governor Ned Lamont signed Senate Bill 5 into law on June 2, 2026. The legislation is designated Public Act 26-15 and carries the title Connecticut Artificial Intelligence Responsibility and Transparency Act (CART Act). The Act is now enacted law. Compliance deadlines run from October 2026 through January 2028 depending on the obligation.
The CART Act creates obligations across five domains. Employers using AI to make hiring or personnel decisions must give prescribed disclosures to affected workers. Employers issuing Worker Adjustment and Retraining Notification Act notices must disclose whether AI informed the layoff decision. Chatbot operators must implement protocols to detect expressions of suicidal ideation among users and respond with appropriate resources. Developers of generative AI systems with over one million monthly users must embed content-provenance data in AI-generated audio, image, and video.
Employers with Connecticut operations who use automated tools in hiring or performance management face disclosure and audit requirements before October 2026. AI companion platform operators and consumer chatbot providers must deploy safety protocols for Connecticut users. Developers of large-scale generative AI systems must build content-provenance infrastructure. Healthcare entities gain a carve-out for FDA-regulated clinical AI but must assess whether AI used in scheduling, billing, or staffing decisions falls within CART Act employment provisions.
The healthcare carve-out exempts AI clinical tools subject to FDA jurisdiction, but AI used in administrative staffing or billing may not qualify. Compliance timelines are staggered. Content-provenance requirements do not apply until January 2028. Whether the employment provisions extend to contractors alongside employees is an open question the Act does not resolve.
Licentium advises clients on state-level AI regulation and can draw on a partner network to assist organisations with multistate AI compliance. Clients deploying automated decision tools in Connecticut or considering product launches involving AI companions or generative systems may wish to review their obligations before the October 2026 threshold. Work we undertake includes AI regulatory compliance assessments, automated decision-tool disclosure drafting, state AI law monitoring, and AI product risk analysis.
