California cements its role as the national testing ground for AI rules

Gov. Gavin Newsom signed an AI executive order this week as California advances multiple pieces of legislation to regulate artificial intelligence, positioning the state against the Trump administration's push for a national standard that would pre-empt state-level AI laws. The order strengthens state procurement standards by requiring companies to disclose their policies on illegal content distribution, model bias, and civil rights violations before winning California contracts. California's multi-pronged regulatory approach is likely to become the de facto national standard because major tech companies—including OpenAI and Anthropic—will adopt its rules to maintain access to the state's economy, the world's fourth-largest. The move echoes a historical pattern where California acts first on tech policy and Congress eventually cedes regulatory authority to states due to gridlock. Newsom, a potential 2028 Democratic presidential candidate, is positioning himself as the counterweight to Trump on AI governance while the White House says it remains open to legislation consistent with its national framework.
