California Pioneers AI Regulation: Anthropic Endorses Groundbreaking Bill
8 Sep
Summary
- Anthropic endorses California's AI regulation bill
- Bill requires transparency and risk mitigation from large AI companies
- Aims to address potential catastrophic risks from advanced AI systems

On September 8, 2025, Anthropic, a prominent AI developer, became the first major tech company to endorse a California bill that would regulate the most advanced AI models. The proposed legislation, S.B. 53, aims to create the first broad legal requirements for large AI companies operating in the state.
If passed, the bill would mandate that these companies publicly share safety-focused guidelines and procedures for mitigating risks from their AI systems. It would also strengthen whistleblower protections, allowing employees to report concerns about severe or potentially catastrophic risks. The bill largely codifies existing voluntary commitments made by the world's largest AI companies, emphasizing transparency and attention to risks.
While the bill has received overwhelming support in the California legislature, it has also faced criticism from industry trade groups who argue it could stifle innovation. However, supporters, including Anthropic, believe the legislation is a necessary step towards ensuring the safe development of advanced AI technologies. As California is home to many leading AI companies, this bill could have a significant impact on the industry nationwide and globally.
