Inside Anthropic’s state-by-state plan to ratchet up AI rules in the US

Anthropic is encouraging U.S. states to adopt increasingly stringent AI regulations rather than aligning on a unified framework, contrasting with OpenAI’s push for common state legislation. Anthropic endorsed California’s 2025 AI regulation law, the first of its kind in the U.S., while OpenAI initially did not take a position on the proposal. Critics argue Anthropic’s strategy could hinder competition, while OpenAI defends its 'reverse federalism' approach as a way to shape national standards.
