California’s legislature closed its 2026 session near midnight on Aug. 31 and sent roughly 30 AI-related bills to Gov. Gavin Newsom, who has until Sept. 30 to sign or veto. The Stauss Firm’s tally splits the pile into 16 AI bills and 8 privacy bills; NBC News counted 26 measures on AI and social media in the final week alone, with OpenAI CEO Sam Altman reaching out directly to Newsom over concerns with one of the measures, per Politico as reported by NBC News.

For small business owners, two bills matter first.

SB 1050, from the synthetic-performer disclosure fight covered last week, would make it unlawful to publish an ad that “prominently includes a synthetic performer” without a clear and conspicuous disclosure. Its companion SB 1111, from Sen. Ashby, folds digital replicas into California’s false-impersonation prohibition. SB 1000, from Sen. Becker, strikes the 1,000,000 monthly user floor in the California AI Transparency Act, meaning every publicly accessible generative system in the state, not just the majors, inherits the manifest and latent disclosure duties the AG enforces.

The other bills draw structural lines. AB 2713, co-authored by Asm. Wicks and Asm. Aguiar-Curry, forces large platforms to disclose provenance data. Asm. Zbur’s AB 1609 imposes chatbot duties on private businesses above $500,000,000 in national gross annual revenue. Sen. Reyes and Sen. McNerney’s SB 947 bars employers from relying solely on an automated system to fire someone; Reyes’s SB 951 requires 90 days’ notice when technology displaces 25% or more of a workforce.

The full slate is catalogued in our 24-bill session roundup.

Four weeks is enough time to add a disclosure step to a content approval workflow. It isn’t enough to build one from scratch after a signing ceremony. Owners running AI-assisted California ads, including those using services like LemonLime that prepare branded content for owner approval, should treat the Sept. 30 deadline as the decision point.
