California AI Bills Await Newsom's September 30 Deadline

Three significant California AI bills have passed the legislature and await Governor Newsom's signature ahead of a September 30 deadline.

Key points:

• SB 947 provides worker protections related to automated decision-making systems

• SB 951 requires 90 days' advance notice before AI-driven workforce displacement affecting 25% or more of a workforce

• SB 503 requires bias-risk disclosure for clinical AI applications

• Newsom separately signed SB 1050, requiring disclosure when ads use AI-generated performers

None of this legislative activity is really about model capability or safety testing—it's about AI's economic externalities: jobs, healthcare bias, and worker protections. Binding law on these issues is arriving well before comprehensive frontier-model oversight.

Why It Matters: HR and workforce-planning teams at companies operating in California should track SB 951's requirements now, ahead of the September 30 deadline, to ensure compliance runway.
