Illinois Gov. J.B. Pritzker signs SB 315 requiring third-party audits for large AI labs

The new Illinois law, signed July 6, mandates annual independent safety audits and updated public safety frameworks for “frontier” AI developers meeting a revenue threshold, making Illinois the first state to impose third-party audit requirements in this area.

Illinois Gov. J.B. Pritzker signed the Artificial Intelligence Safety Measures Act (S.B. 315) on Monday in Chicago, making Illinois the first state to require third-party safety audits for the largest artificial intelligence developers, according to multiple reports. The ceremony followed passage of the measure by the Illinois legislature earlier this year.

Under S.B. 315, the audit requirement applies to “frontier” AI labs, defined in the reporting as developers with more than $500 million in revenue. Those companies must obtain annual third-party evaluations of their safety plans, with the stated goal of securing oversight by independent experts without financial conflicts of interest.

The law also requires large frontier model developers to create, publish, and annually update an AI framework. Reporting on the bill description says the framework must include assessments addressing catastrophic risks and cybersecurity, alongside other safety-related elements described in the statute.

Supporters and the governor’s office described the audits and reporting requirements as a response to the pace of AI deployment and the difficulty of oversight when national rules are not in place. The Hill reported that Pritzker said people “want protection from the risks of AI,” and that the bill was intended to establish protections through independent scrutiny of safety plans.

The reporting also indicates the bill mirrors elements of legislation previously enacted in California and New York, while adding the new annual third-party audit requirement for large frontier labs. According to The Hill, the approach is designed to create a repeatable safety-review process and to reduce reliance solely on company self-assessments.

According to The Hill, S.B. 315 passed the Illinois legislature earlier this year with bipartisan support. The reporting further said endorsements from major AI developers, including OpenAI and Anthropic, were cited in connection with the measure.

Outside Illinois, the bill enters a policy landscape in which states have increasingly moved to regulate advanced AI systems while lawmakers at the federal level have debated additional frameworks. The Hill reported that Washington has “stalled” on much of the AI legislation underway.

Implementation timing and enforcement details were not fully specified in the available reporting, and no state administrative guidance or posted statute text was provided in the materials reviewed for this story. As a result, the practical timeline for audits, the specific compliance reporting process, and the scope of penalties for noncompliance should be confirmed through the enacted law and any subsequent Illinois agency rulemaking or guidance.

Why It Matters

The bill creates a repeatable compliance mechanism for advanced AI providers by requiring independent, annual safety audits rather than relying only on internal company review.
By setting a state-level requirement for frontier labs meeting a revenue threshold, Illinois is increasing regulatory pressure on the most resource-intensive developers while other states and federal efforts remain under development.
The annual publication and update requirement for a safety framework may expand transparency about risk assessments, including catastrophic risks and cybersecurity, for covered models.
Because the measure was signed at the state level, it adds to the ongoing debate over federal versus state authority to regulate AI, potentially increasing the patchwork of compliance obligations for companies operating across jurisdictions.
The law’s impact will depend on how Illinois defines key terms in the enacted text and how the state enforces compliance, including any deadlines and penalties that were not detailed in the available reporting.
