Governor Newsom's new executive order positions California to require a shutdown mechanism for frontier AI models, escalating the state-vs-federal fight over AI oversight.
Gavin Newsom issued an executive order Friday directing state agencies to explore mandating a 'kill switch' for frontier AI models, the most aggressive state-level oversight move yet. The order is part of a broader push to make California, not Washington, the default regulator of advanced AI systems operating in the country's largest state economy.
The move comes the same week Anthropic's Dario Amodei proposed a three-step plan for slowing AI development, and as the Trump administration signals hostility to AI regulation, calling backlash against the technology a partisan hoax.
A state-mandated shutdown requirement would force every major AI lab selling into California to build compliance infrastructure now, regardless of what happens federally. Operators building on frontier models should expect fragmented, state-by-state compliance costs to become a real line item in 2027 budgets.
