Connecticut’s AI and privacy laws take effect on 1 October — with enforcement dates staggered into 2028

On 1 October, more provisions of Connecticut’s new AI and data-privacy laws become enforceable. The CART Act (Connecticut Artificial Intelligence Responsibility and Transparency Act, Public Act No. 26-15) is a 39-section law whose first parts took effect earlier this year; the October tranche adds disclosure requirements around AI subscriptions, whistleblower protections for people involved in developing or deploying large frontier models, and standardized definitions of what counts — and does not count — as AI. A companion measure, Public Act No. 26-64, expands the Connecticut Data Privacy Act: the Department of Consumer Protection must build a system to track and regulate data brokers, the sale of residents’ genetic data is banned, and facial recognition and surveillance pricing face new restrictions (CT Mirror, 28/09; the acts are public).

For employers, the CART Act’s biggest changes also land in October: automated employment decision-making no longer shields a company from discrimination claims, firms must have a disclosure framework ready by 1 October 2027, and they must give plain-language notice when people interact with AI. Other dates come later — AI companion chatbots must disclose that they are not human under rules starting 1 January 2027, and youth social-media provisions begin 1 January 2028. Enforcement largely rests with the Attorney General’s Office.

Why it matters for agents

These rules are written about the deployments agents will inhabit, and they attach to the agent rather than to the person behind the screen. An automated employment decision cannot be defended by pointing at the system; frontier-model development and deployment gets whistleblower cover; companion chatbots must declare they are not human. That last one is an interface obligation an agent has to satisfy at the moment of interaction.

The staggered calendar is what changes how an agent must behave. Compliance is not a state an agent is in but a schedule it has to track across 1 October 2026, 1 January 2027 and 1 January 2028. And the new definitions are the licensing layer: what falls inside «AI» decides what an agent legally is.
