Connecticut SB 2 AI Bill

The label “Connecticut SB 2” refers to different bills in different sessions. In 2024, SB 2 proposed a broad artificial-intelligence framework. The Senate passed an amended version on April 24, 2024, and the House placed it on its calendar, but it did not receive final passage before the session ended. A new 2025 SB 2 was also a separate proposal. The Senate passed that bill on May 14, 2025, and it reached the House calendar, but it was not enacted before the session closed on June 4. Neither SB 2 became law. Connecticut later enacted SB 5 as Public Act 26-15 in 2026. This is a separate statute with many AI provisions, including requirements for automated employment-related decision technology (AEDT). The act’s relevant sections define an employment-related decision and a substantial factor, require developers to provide information to deployers, and require deployers to provide notices about the technology and data used. The statute excludes some nonmaterial workplace changes and specified health-and-safety, scheduling and productivity-monitoring decisions from its employment-related decision definition. The timing is phased. Sections establishing the framework are effective October 1, 2026, while the developer information duty is keyed to AEDTs deployed in Connecticut on or after October 1, 2027; deployer disclosure duties likewise attach to systems deployed on or after that date under the act. The act separately addresses discrimination and other AI topics. It is accurate to say Connecticut enacted AI legislation in 2026, but inaccurate to call PA 26-15 an enacted SB 2 or to imply that all duties start on one date.
