Illinois Passes Nation's Strongest AI Safety Bill Requiring Independent Audits of Frontier AI Labs

Summary

The Illinois House of Representatives passed Senate Bill 315 on Wednesday, establishing what experts consider the nation's most stringent AI safety regulations to date. The bill requires frontier AI labs—including OpenAI, Anthropic, and Google DeepMind—to undergo independent third-party audits of their safety practices rather than relying solely on self-certification. Governor JB Pritzker has indicated he plans to sign the legislation into law, moving it closer to becoming enforceable policy.

SB 315 significantly advances beyond existing state-level AI regulations in California and New York, which primarily mandate transparency and incident reporting. Illinois' bill is the first to require independent verification that AI labs actually adhere to their own published safety commitments. According to policy experts, the current system amounts to "AI companies grading their own homework"—a dynamic the bill aims to address through mandatory external accountability. Big Four accounting firms and specialized AI evaluation organizations are expected to serve as auditors.

Both OpenAI and Anthropic have publicly endorsed the bill, with OpenAI's chief of global affairs praising the "thoughtful framework for frontier AI safety." The legislation arrives as Congress has failed to pass meaningful federal AI safety laws, leaving state legislatures to establish a regulatory baseline. Illinois representatives view the bill as a potential template for federal legislation, positioning the state as a leader in AI governance. While some tech industry trade groups have opposed the measure, the broad support from major AI companies suggests acceptance of independent auditing as an emerging industry standard.
