Munger, Tolles & Olson Partner Jonathan Blavin and Associate Shannon Aminirad co-authored a Bloomberg Law article, titled “Tech Giants Brace for Regulatory Impact as CA Passes New AI Laws.”

In the article, Jonathan and Shannon analyze three major California bills – SB 243, AB 56 and AB 1043 – which reflect a significant shift in how the state is regulating artificial intelligence and protecting minors online. SB 243 requires chatbot operators to disclose AI interactions and implement protocols addressing self-harm and suicide risk among users. AB 56 introduces “tobacco-style” warnings for minors using AI tools on social media. And AB 1043, which takes effect in 2027, mandates age-verification mechanisms for AI platforms.

Jonathan and Shannon highlight how these laws signal a broader trend toward imposing legal obligations on technology companies for both AI-driven content and youth safety, and how this evolving regulatory framework may spark constitutional, federal and preemption challenges, including under the First Amendment, Section 230 of the Communications Decency Act and the Children’s Online Privacy Protection Act.

“The new legislation underscores the complex compliance landscape ahead,” Jonathan and Shannon write. “California may be one of the first states to take these steps, but it’s unlikely to be the last.” They caution that early litigation will shape how far states may go in mandating AI disclosures and age-based online safety measures.

For technology companies, platform operators and legal advisors, this article offers actionable guidance on navigating a rapidly shifting regulatory environment, including design choices for youth-facing platforms, governance of AI interactions and monitoring state‐by‐state compliance developments.
