Confirmed in a primary source 30 Sept 2026 State

California signed thirteen AI laws on its deadline day, vetoed three, and refused the federal government's new name for the technology.

September 30 was the last day Governor Gavin Newsom could act on bills passed this session, and he used it: thirteen artificial intelligence bills signed, covering workplace surveillance, automated employment decisions, notice when AI causes mass layoffs, health care AI, two rewrites of the state AI Transparency Act, gene synthesis equipment, digital replicas and lawyers delegating work to AI. Three AI bills were vetoed, including one on mental health professionals and AI and one on AI in health care services.

He also signed an executive order, EO-N-10-26, requiring California agencies to keep saying artificial intelligence "notwithstanding any rebranded or different terminology used by the federal government," one day after President Trump ordered federal agencies to say Super Intelligence instead. The caveat that matters is that almost none of this binds a model developer: the laws reach employers, hospitals, lawyers and platforms that deploy these systems, not the companies that train them.

Until now

States wrote AI rules one at a time, and the federal government and California were pointed roughly the same way.

Now

California enacted thirteen in a day, vetoed three, and put its disagreement with Washington into an executive order about what the technology is called.

Deadline days produce piles of paper, and the pile is not the signal. The signal is what the state chose to reach for. Read the thirteen together and they are almost all about deployment: an employer watching a worker, a hospital using a system on a patient, a lawyer handing a brief to a model, a platform labelling a file. The one bill in the list that touches capability rather than use is about gene synthesis equipment, and it regulates machines, not models. That is a government legislating where it has jurisdiction and where the harm is visible, which is a choice, not an oversight. The three vetoes point the same way: all three would have added duties inside health care, mental health practice and public employment, and all three were refused.

The executive order is the part that will be quoted in a year. One day earlier the President signed an order instructing the whole executive branch to stop saying artificial intelligence and start saying Super Intelligence, with a sixty-day deadline for proposed statutory language. One day later the governor of the state where most of these companies are headquartered ordered his own agencies to ignore it, in writing, and used the order's text to accuse the administration of failing to act on risks it has documented. Two governments that have to share the same companies now disagree in official documents about what the thing is called, which is what a jurisdictional fight looks like before it reaches a court.

How it got here

Sep 9
California creates the first state system of independent AI auditors and makes using one a defence. Edition 017's card, the parent of this one.
Sep 23
The Governor names outside experts to deliver on his earlier AI executive order, including work on a shutdown mechanism.
Sep 29
President Trump signs Inaugurating the Era of Super Intelligence, ordering federal agencies to replace artificial intelligence and AI with Super Intelligence and SI, with a 60-day deadline for proposed statutory language.
Sep 30
Thirteen AI bills signed, three vetoed, and EO-N-10-26 orders California agencies to keep using artificial intelligence regardless of federal usage.
Who has to react
Every employer in California that runs an automated hiring, scheduling or discipline system and now needs a human in the loop and a notice procedure; the hospitals and clinicians covered by the two health care AI bills that were signed, and the mental health practitioners whose bill was not; the compliance departments at every multistate employer that has to run one rule in California and another everywhere else; the six chief executives who signed a voluntary federal accord the previous day, none of whose four commitments is mentioned in any of these thirteen laws; the Office of Management and Budget, which owes an implementation memorandum on America.gov by December 28 and now has to write it in a vocabulary one large state refuses to use; the New York City council members hearing their own AI package on October 5; and every state legislature that has been waiting to see how far California would go before drafting its own.

The evidence

ObservedWednesday September 30, 2026, established at the Governor's own releases at gov.ca.gov. Signed, by number and author as the Governor's office lists them: AB 1331 (Elhawary) and AB 1883 (Bryan) on workplace surveillance and surveillance tools; SB 947 (McNerney) on automated decision systems in employment; SB 951 (Gomez Reyes) on notice of technological displacement; AB 1979 (Bonta) and SB 503 (Weber Pierson) on health care AI services; AB 2713 (Wicks) on system provenance data under the California AI Transparency Act and SB 1000 (Becker) on the same Act; AB 1864 (Berman) on gene synthesis equipment safety; AB 2392 (Fong) on AI training in public higher education; SB 574 (Umberg) restricting what legal work an attorney may hand to AI; SB 1111 (Ashby) on digital replicas; and SB 1159 (Cabaldon) on AI transparency and governance.

The whole observation, as recorded

The Governor's stated reason: "AI should expand opportunity, not come at the expense of workers and families." The same day's legislative update records 176 bills signed in total, 101 Assembly and 75 Senate, and 29 vetoed. Three of the 29 are artificial intelligence bills and we name them because the vetoes are the part nobody reports: AB 2575 (Ortega), health care services and artificial intelligence; AB 2656 (Petrie-Norris), notice to public employees when artificial intelligence performs a service; and SB 903 (Padilla), mental health professionals and artificial intelligence. Yesterday's edition flagged four unsigned AI bills as the day's largest fuse, one of them on mental health practice. Three of those four were signed and the mental health one was vetoed. Then the executive order. EO-N-10-26 directs California agencies to use artificial intelligence and AI regardless of federal usage, and describes the federal rebrand as a distraction from what it calls the administration's "impotent and craven failure to take action to address well-documented emerging security and safety risks." The Governor, on the federal order: "Super intelligence is clearly not coming from the White House." On the previous day in Washington: "What I heard in Washington, D.C., yesterday is bullshit and that should scare the hell out of everybody," comparing the refusal of AI regulation to a drug company saying it does not need the Food and Drug Administration. What is not established: any enforcement record, any effective date detail we have verified bill by bill, and whether any of the thirteen reaches model training rather than deployment.

Established

The Governor of California signed thirteen named artificial intelligence bills on September 30, 2026, the last day of the signing window, and his office published the list.
He vetoed three artificial intelligence bills the same day: AB 2575 on health care services, AB 2656 on notice to public employees, and SB 903 on mental health professionals.
He signed executive order EO-N-10-26 requiring California agencies to use the terms artificial intelligence and AI notwithstanding any different terminology used by the federal government.
176 bills in total were signed and 29 vetoed on September 30, 2026.
The federal executive order replacing artificial intelligence with Super Intelligence across the executive branch was signed on September 29, 2026 and carries a 60-day deadline for proposed statutory language.

Not established

That any of the thirteen laws regulates how a frontier model is trained. On the published subjects, they reach deployment, not development, with gene synthesis equipment the one exception and it regulates machines.
That the vetoes were about AI. No veto message is quoted in what we read, and California vetoes often turn on cost or on duplication with existing law.
What any of this costs or when it bites. We have not verified effective dates bill by bill, and several California AI statutes have carried January effective dates.
That the naming order has any legal effect outside California state agencies. It directs state usage and creates no obligation on anyone else.
That the state and federal positions are in legal conflict. A disagreement in two executive documents about terminology is not a preemption question until somebody raises one.

Why it weighs this much

Signal strength

CostMedium

CommitmentHigh

ReversibilityHard

PersistenceStructural

Cost is medium. Signing bills costs a governor political capital with the industry concentrated in his state, and he spent some of it, but it is not capital expenditure and the enforcement burden falls on agencies and employers rather than on him. Commitment is high, which is the leg that carries this. These are statutes with his signature on them, not pledges or frameworks, and the three vetoes are equally committal in the other direction: he refused specific duties and will be quoted on it. Reversibility is hard. Repealing a California statute takes the legislature; the deadline has passed and cannot be reopened; and the vetoed bills have to start again next session. The executive order is the soft part and can be rescinded by the next governor. Persistence is structural because California deployment rules function as national rules for any employer or platform that operates in the state, which is how the state's privacy law worked, and because a formal disagreement between a state and the federal executive over the vocabulary of a technology tends to outlive both documents.

What to watch

strengthens A second state enacts five or more artificial intelligence statutes in one session, or New York City passes its ten-bill AI package with the per-instance validation penalty intact, by June 30, 2027.
weakens Federal legislation or an executive action preempting state AI rules is enacted or signed, or a court enjoins any of the thirteen California statutes, by June 30, 2027.

The words

Automated decision system: Software that makes or substantially informs a decision about a person, such as who gets hired, promoted or disciplined.
Veto: A governor's refusal to sign a bill. In California a bill the governor neither signs nor vetoes by the deadline becomes law without a signature; a veto stops it.
Provenance data: Machine-readable information attached to a file recording what made it, used to tell AI-generated content from the rest.
Digital replica: A synthetic copy of a real person's voice or likeness, convincing enough to stand in for them.
