OpenAI and Google Oppose Massachusetts AI Safety Rules Supported by Anthropic

The ongoing debate over AI safety regulations in Massachusetts has revealed a significant divide among leading industry players. OpenAI and Google have publicly opposed proposed safety rules, while Anthropic stands in support of these regulations, which are considered among the most stringent in the nation.

The Massachusetts Senate passed an economic development bill in July 2026 that includes provisions targeting AI developers generating over $500 million in AI-derived revenue or spending more than $1 billion on research and development. The legislation mandates the publication of safety frameworks focused on catastrophic risks and grants enforcement authority to the state attorney general.

Anthropic is advocating for even more rigorous measures, proposing independent risk assessments every four to six months, which would make Massachusetts’ regulations more demanding than existing state laws. In contrast, OpenAI argues for a narrower approach, warning that aggressive state-by-state regulation could create a fragmented legal landscape that delays beneficial AI developments.

Google has aligned with OpenAI in opposing the stricter provisions, emphasizing the need for consistency across regulations. The Greater Boston Chamber of Commerce has raised concerns that overly restrictive rules could deter AI investments in the state.

As the legislation undergoes bicameral negotiations, the final version may differ significantly from what the Senate initially passed. This regulatory conflict could have broader implications for Anthropic's competitive position and valuation, especially as market sentiment reacts to the evolving landscape of AI safety regulations.
