Connecticut

Partially in forceApproach: Targeted omnibus AI act; first wave in force from October 1, 2026

Connecticut enacted the CART Act (SB 5, Public Act 26-15) on May 27, 2026, after Senator Maroney's framework bills passed the Senate in 2024 and 2025 without becoming law. The act regulates named uses: automated employment decision tools, AI companions, frontier-developer whistleblower protections, content provenance, AI-related layoff disclosures, and online safety for minors. Public Act 26-100, approved June 2, 2026, replaced its subscription rule and moved its verification pilot to October 2027. Most provisions take effect October 1, 2026, the companion rules on January 1, 2027, developer and deployer duties for employment tools deployed from October 1, 2027, and platform duties for minors on January 1, 2028. A separate 2026 law bans surveillance pricing by retailers and delivery services from July 1, 2027.

Key points

  • SB 5, the CART Act, was signed May 27, 2026, after the 2025 version died under veto threat. The final text requires a plan for an AI regulatory sandbox and adds youth online-safety provisions.
  • The act covers named uses (employment tools, companions, frontier developers, provenance, and minors online), with duties phasing in from October 1, 2026, when the first wave took effect, to January 1, 2028. It sets no general risk-management regime.
  • The Connecticut Data Privacy Act's profiling and automated-decision provisions already apply to AI.
  • A separate law, Public Act 26-130, bans surveillance pricing by retailers and delivery services from July 1, 2027.

Laws and instruments

Connecticut Artificial Intelligence Responsibility and Transparency Act (CART Act)

SB 5, Public Act 26-15; signed May 27, 2026
Phasing in

A 39-section omnibus that regulates named uses: automated employment decision tools (developer information duties and deployer notices for tools deployed from October 1, 2027, and using a tool is no longer a defense to discrimination claims), AI companions with protections for minors, frontier-developer whistleblower protections, generative content provenance, AI-related layoff disclosures in WARN notices, and online safety duties for platforms used by minors. The employment-tool rules are enforced by the attorney general as an unfair trade practice, with a 60-day cure period for violations through 2027 and no private right of action. A follow-up law, Public Act 26-100 (approved June 2, 2026), replaced the act's subscription rule with a narrower one from October 1, 2026 and moved its Department of Consumer Protection pilot for independent verification organizations to October 1, 2027, running to March 31, 2031.

Effective: Most provisions October 1, 2026; AI companions January 1, 2027; employment-tool duties for tools deployed from October 1, 2027; verification pilot October 1, 2027 (Public Act 26-100); platform duties for minors January 1, 2028

Surveillance pricing limits (Public Act 26-130)

HB 5563, section 11; approved June 4, 2026
Phasing in

Bars retail sellers and third-party delivery services from surveillance pricing, meaning prices customized to a consumer from personal data gathered through tracking technology, and requires other businesses that use it online to label the price 'THIS PRICE WAS INCREASED USING YOUR PERSONAL DATA.' Discounts, loyalty programs, and cost-based price differences are exempt. Earlier 2026 versions were repealed before they took effect.

Effective: July 1, 2027

Recent developments

October 14, 2026
Connecticut Attorney General

Forty attorneys general press for privacy and safety terms in any sale of Character.AI

Attorneys general from 39 states and the District of Columbia filed a notice in the bankruptcy case of Character Technologies, the company behind Character.AI, asking that any sale or transfer of its business or assets carry privacy and safety protections for children and other users. They said the company holds a large volume of sensitive data, including private chatbot conversations, and that its voluntary limits on minors' access are not compulsory and could be reversed by a buyer. The states reserve the right to object to any proposed sale or plan.

Most provisions take effect October 1, 2026, the companion rules on January 1, 2027, developer and deployer duties for employment tools deployed from October 1, 2027, and platform duties for minors on January 1, 2028.
