California state lawmakers have ramped up efforts to regulate artificial intelligence (AI) in their latest session, putting the Golden State on a collision course with a Republican effort to impose a national ban on such policies.
As the AI race heats up, President Trump and GOP lawmakers have sought to eliminate regulations they argue could stifle innovation, while states forge ahead with attempts to place guardrails on the technology.
But California sits in a unique position. As the home of Silicon Valley and the center of the AI boom, it could play an outsized role in defining the future of AI regulation — both inside and outside its borders.
“We dominate in artificial intelligence. We have no peers,” California Gov. Gavin Newsom (D) said Wednesday.
“As a consequence of having so much leadership residing in such a concentrated place, California, we have a sense of responsibility and accountability to lead, so we support risk-taking, but not recklessness,” he added.
The California legislature passed several AI bills in the session that ended in mid-September.
Most closely watched is Senate Bill 53, legislation that would require developers of large frontier models to publish frameworks detailing how they assess and mitigate catastrophic risks. It is currently awaiting the governor’s signature.
“Because California is such a large state, any AI regulations that it enacts could serve as a potential de facto national standard,” said Andrew Lokay, a senior research analyst at Beacon Policy Advisors.
“Companies could decide to simplify compliance by applying California’s rules to their operations beyond the Golden State,” he continued.
Washington, D.C., is taking notice.
Sriram Krishnan, a White House senior policy advisor for AI, argued last week that they “don’t want California to set the rules for AI across the country.”
Rep. Kevin Kiley (R-Calif.) acknowledged his home state “continues to be the center of breathtaking innovation worldwide” but called into question whether it should be the one to regulate AI.
“The notion that this is the right body to regulate the most powerful technology in human history, whose workings are actually largely beyond the understanding even of the technology’s creators, is a fairly fantastical notion,” he said at a hearing last week.
“I do think the risk that California is going to drive AI policy for the entire country is a very real one, and I think that a national framework that seeks to stop that from happening is needed and appropriate,” Kiley added.
With a heavy focus on boosting innovation, the Trump administration and GOP lawmakers have increasingly pushed to preempt state AI laws that they argue could weigh down the technology.
Earlier this year, several Republicans sought to include a provision in Trump’s “big, beautiful bill” that would have barred state AI regulation for 10 years.
The effort exposed a rift within the GOP. Some lawmakers, including Sen. Marsha Blackburn (R-Tenn.) and Rep. Marjorie Taylor Greene (R-Ga.), voiced concerns about the restrictions on states’ rights and the preemption of AI-related protections. The Senate ultimately voted 99-1 to remove the provision.
Despite the setback, Sen. Ted Cruz (R-Texas), chair of the Senate Commerce Committee, said last week that the moratorium push is “not dead at all.”
This focus on state laws was also reflected in Trump’s AI Action Plan, which called for limiting funding to states over AI rules, tasking the Federal Communications Commission (FCC) with evaluating whether state laws interfere with its mandate and reviewing Federal Trade Commission (FTC) investigations that could “unduly burden AI innovation.”
As the president charges ahead with this endeavor, Lokay noted that California’s push for AI regulation could provide more momentum to efforts to preempt state rules. However, he underscored that there are still many obstacles to passing such a moratorium.
Beyond GOP infighting, Congress has long struggled to pass tech legislation, with kids’ online safety and digital privacy efforts repeatedly falling short. While lawmakers have taken an interest in AI, a federal framework still appears far off.
“A year ago my response to this kind of legislation was the states should not be doing this. We should leave it to the federal government,” Appian CEO Matt Calkins said in a statement to The Hill. “One year later and the situation has changed. The federal government is not taking the lead.”
“In fact, it is flirting with the idea of forbidding or preventing states from creating AI regulation, and so, in the face of that aggressive pronunciation of a federal level interest in AI regulation, I do think it should come from somewhere,” he continued. “I’m sorry to see it come from the states, but I think that is one possible way we could arrive at it, it’s just going to be more painful.”
Anthropic appeared to make a similar calculus in throwing its support behind California’s S.B. 53. The AI firm endorsed the legislation in early September.
“While we believe that frontier AI safety is best addressed at the federal level instead of a patchwork of state regulations, powerful AI advancements won’t wait for consensus in Washington,” it wrote in a blog post earlier this month.
The reception to S.B. 53 so far has been markedly better than its predecessor. The bill, put forward by California state Sen. Scott Wiener (D), is widely viewed as a successor to S.B. 1047 from last year, which cleared the state legislature but was vetoed by Newsom.
S.B. 1047 offered a much more heavy-handed approach to AI regulation, pushing for models to undergo safety testing before public release and seeking to hold developers liable for potential severe harm.
The measure drew a rare rebuke from several California Democrats in Congress. Former Speaker Nancy Pelosi, Reps. Zoe Lofgren, Ro Khanna and others argued the legislation was overly restrictive and sought to tackle an issue that should be left to federal lawmakers.
Anthropic offered lukewarm support for S.B. 1047 last year, suggesting “its benefits likely outweigh its costs” after some amendments were made to the legislation.
S.B. 53 hasn’t won over all of its detractors. OpenAI has remained critical of California’s approach, warning Newsom of the risk they could “inadvertently create a ‘CEQA for AI innovation.’” The California Environmental Quality Act (CEQA) has faced criticism for making it more difficult to build in the state.
But the state’s AI bill has largely received less pushback this year. Khanna told The Hill he views the legislation as a “strong start,” underscoring that “they made a number of revisions on it that avoid downstream excessive liability.”
And Newsom hinted at his support Wednesday, noting that “we have a bill that’s on my desk that we think strikes the right balance, and we worked with industry, but we didn’t submit to industry.”
