On June 2, 2026, Connecticut Governor Ned Lamont signed Senate Bill 5 into law, designated as Public Act 26-15 and also known as the Connecticut Artificial Intelligence Responsibility and Transparency Act (the “CART Act” or “Act”).1 The CART Act is among the most comprehensive state AI laws enacted to date, creating distinct obligations for employment-related automated decision tools, consumer chatbots, frontier-model developers, generative-AI provenance, and online platforms used by minors, while also addressing AI applications in healthcare through targeted carveouts and innovation initiatives.
