Summary

Connecticut's 2025 comprehensive AI bill, Substitute SB 2, passed the Senate on May 14, 2025 but only reached the House Calendar on May 16, 2025; the official CGA history does not show House passage. The current live successor is Substitute SB 5 (2026), An Act Concerning Online Safety, which passed the Senate as amended on April 21, 2026 and passed the House in concurrence on May 1, 2026 per the CGA bill-history page (retrieved 2026-05-06). As of this verification, the official status page does not yet show a Public Act number or gubernatorial signature.

SB 5 is broader than the 2025 SB 2 entry this page originally tracked. The amended bill covers AI subscription disclosures, frontier-developer whistleblower protections, AI regulatory sandbox changes, AI companions, automated employment-related decision technology, Connecticut AI Academy and workforce programs, state agency AI use, social media platforms and minors, and related governance structures. The Office of Legislative Research bill analysis states a general effective date of October 1, 2026, with later effective dates for some provisions including frontier-developer anonymous-reporting processes by January 1, 2027 and AI sandbox changes on July 1, 2027.

Compliance teams operating in Connecticut should treat this page as a pending-bill tracker until the executive-action/Public Act record is available. The most actionable near-term sections are automated employment-related decision technology disclosures and notice duties, frontier-developer whistleblower protections, and consumer disclosures for AI subscriptions. SB 5 uses a mixed enforcement model: several violations are treated as Connecticut Unfair Trade Practices Act violations enforced solely by the Attorney General, while frontier-developer whistleblower violations carry a civil penalty of up to $1,000 per violation.
