Connecticut
Connecticut is the state where the comprehensive approach keeps almost happening. Senator Maroney's framework bill passed the Senate in successive sessions without becoming law, and the 2026 session's SB 5 continued the effort. What has actually been enacted is narrower, including 2026 limits on AI-driven dynamic pricing, so the state sits in the growing category of targeted-law jurisdictions with a framework still pending.
Key points
- The SB 2 lineage finally became law: SB 5, the CART Act, was signed May 27, 2026 after the 2025 version died under veto threat, negotiated to include a governor-backed regulatory sandbox and youth online-safety provisions.
- The act is targeted rather than comprehensive: it regulates named high-risk uses, employment tools, companions, frontier developers, provenance, and minors online, with duties phasing in from October 1, 2026 to 2028, rather than a general risk-management regime.
- The Connecticut Data Privacy Act's profiling and automated-decision provisions already apply to AI.
Laws and instruments
Connecticut Artificial Intelligence Responsibility and Transparency Act (CART Act)
The broadest state AI law enacted in 2026 and the law the register previously recorded as stalled. A 39-section omnibus that regulates specific high-risk uses rather than imposing a Colorado-style impact-assessment regime: automated employment decision tools (developer information duties and deployer notices, with using a tool no longer a defense to discrimination claims), AI companions with minor protections, frontier-developer whistleblower protections, generative content provenance, AI-related layoff disclosures under WARN notices, subscription AI disclosures, and online safety duties for platforms used by minors. Enforced by the attorney general as an unfair trade practice with a cure period through 2027 and no private right of action; a Department of Consumer Protection safe harbor confers a presumption of compliance.
2026 targeted measures (including AI dynamic-pricing limits)
Narrower consumer-protection measures enacted in 2026, including restrictions on AI-enabled dynamic pricing.
