Meta filed November 4, 2026; Google and TikTok filed their own federal suits the same week. Each sued Attorney General Rob Bonta, arguing the law violates the First Amendment by overriding how platforms arrange and recommend content, and that Section 230 preempts it. They ask the courts to block enforcement before it takes effect on January 1, 2027. No order yet.

What it does
AB 1709 prohibits covered platforms from providing users under 16 with algorithmic feeds, autoplay, notifications, endless scroll, and other features the state classifies as addictive. Before providing those features, a platform must obtain an age signal through California's Digital Age Assurance Act or use an alternative age-determination process. An under-16 account may remain only with the restricted features removed. Knowing violations can draw penalties of up to $50,000 per affected minor and negligent violations up to $25,000. Governor Newsom signed the bill on September 10, 2026 as Chapter 183.
What’s at stake
A platform cannot identify the under-16s without sorting everyone else too. That means more age data, stronger pressure for government ID or biometric checks when weaker signals are challenged, and new stores of sensitive information attractive to hackers and authorities. The law also limits young people's access to recommendation systems that help them find journalism, political discussion, art, religious material, and supportive communities unavailable offline.
Our take
California has replaced parental judgment with a state-backed access system for millions of people. The target is described as addictive design, but the enforcement machinery is mass age verification. Every adult must be checked so the state can restrict every teenager, and the same identity pipe can be reused for whatever category of speech or user lawmakers decide to gate next.
