Illinois Governor Signs SB 315 Establishing Nation's Strongest AI Safety and Accountability Framework

Governor JB Pritzker has signed the Artificial Intelligence (AI) Safety Measures Act, known as SB 315, making Illinois the first state to mandate independent third-party safety audits for large-scale AI systems. The bipartisan legislation requires major AI developers to disclose safety practices, report significant incidents, and implement robust risk mitigation strategies. This move positions Illinois as a national leader in AI regulation, aiming to protect consumers and workers while providing a clear legal framework for technological innovation within the sector.

SB 315, which takes effect on January 1, 2027, establishes a comprehensive framework for transparency and accountability among developers of the most advanced AI systems. Under the new law, these companies must publicly disclose their safety practices and maintain rigorous compliance processes to identify and mitigate potential risks. Notably, Illinois is the first state to require that these covered AI systems undergo regular safety audits conducted by independent third-party experts who are free from financial conflicts of interest.

In addition to corporate requirements, the legislation introduces significant protections for the workforce and the public. It creates confidential reporting channels and whistleblower protections for employees who raise concerns regarding AI safety, ensuring that internal risks can be flagged without fear of retaliation. State leaders, including Lieutenant Governor Juliana Stratton and State Representative Daniel Didech, emphasized that these guardrails are specifically designed to prevent catastrophic outcomes and protect vulnerable populations, such as children, from the unintended consequences of frontier AI models.

The bill received support from both safety advocates and major industry players, including Anthropic, which was the first AI lab to back the legislation. Cesar Fernandez, Anthropic’s Head of U.S. State and Local Government Relations, noted that the law pairs transparency with independent verification, setting a new standard for the industry. Other organizations, such as the Secure AI Project and Encode AI, highlighted that Illinois has surpassed existing frameworks in California and New York by moving beyond self-reporting to mandatory external oversight. Governor Pritzker framed the law as a necessary state-level intervention in the absence of federal action, aiming to provide regulatory certainty for companies while prioritizing public safety.
