Governor Gavin Newsom has until midnight tonight to sign or veto SB 1000, SB 947, and the remaining items on California’s AI docket, and under the state’s no-pocket-veto rule any bill still on his desk becomes law anyway. SB 1000 is the one to watch: it carries an urgency clause, meaning the moment his pen touches paper the AI Transparency Act’s compliance perimeter expands around every business using generative AI to talk to customers.

The structural shift is in a single deleted number. Per Kelley Drye and Vorp Labs, SB 1000 removes the one-million-monthly-user threshold that currently defines a “covered provider.” Strip that out and the statute’s latent-provenance disclosure obligations snap onto the small operator running AI-written landing pages, not just the frontier labs it was drafted for. Vorp Labs notes the bill also swaps the AI detection tool for a “disclosure verification tool” and drops the optional manifest disclosure. Civil penalties run $5,000 per violation per day.

Newsom has been clearing the deck in sequence. He signed SB 1050’s AI-generated advertising disclosure law on September 16, took AB 1609’s chatbot disclosure rule on September 28, and earlier enacted SB 813’s independent auditor regime. AB 1609 applies above $500 million in revenue; SB 947, the No Robo Bosses Act, has a July 1, 2027 operative date; SB 1050’s synthetic-performer rules kick in January 1, 2027.

SB 1000 is different. There’s no runway. Our prior guide to today’s deadline laid out the stakes; the signature itself is the compliance trigger. California keeps writing AI rules at the pace of a legislative session and enforcing them at the pace of a press release.
