Overview

• Senate Majority Leader Robert Rodriguez amended SB4 to postpone Colorado’s AI law from February 2026 to no earlier than May, tying implementation to work completed during the 2026 regular session.
• After Rodriguez reconfigured the Appropriations Committee to expand the Democratic edge to 5–2, the panel advanced SB4 on a 4–3 vote and sent it to the full Senate.
• Rodriguez removed Sen. Jeff Bridges from Appropriations and added Sens. Katie Wallace and Mike Weissman, a rare mid‑session membership change aimed at moving the bill.
• SB4 would shift more compliance obligations to AI developers rather than deployers such as schools and local governments, and it is backed by unions and consumer advocates as talks continue with the governor’s office and tech firms.
• A rival House measure, HB 1008 (HB 8), was stripped down to a clean delay of the 2024 law to Oct. 1, 2026 and remains pending, while SB4’s fiscal estimate has risen to about $4.8 million with additional state agencies affected.
