On 6 July 2026, Illinois Governor JB Pritzker signed Senate Bill 315, the Artificial Intelligence Safety Measures Act (AISMA), into law. Illinois becomes the third US state to pass frontier AI legislation and the first to require independent third-party safety audits as a statutory condition for frontier model deployment. The Act takes effect on a phased schedule, with certain provisions contingent on further rulemaking by designated state agencies.
AISMA applies to developers of frontier AI models meeting capability thresholds defined in the Act. Key statutory obligations include conducting and publishing independent third-party safety audits before deploying a covered model, implementing and maintaining an AI safety programme, disclosing specified technical information about covered models to the Illinois Attorney General, and reporting safety incidents to designated state authorities. AISMA is the first US state law to impose mandatory independent third-party audits as a statutory condition for frontier model deployment.
Developers of large-scale AI models marketed or deployed with Illinois users face direct compliance costs, including third-party audit expenditures and disclosure obligations to the Attorney General. Technology companies, AI foundation model providers, and enterprise AI deployers now face a patchwork of state-level frontier AI obligations, with AISMA joining similar legislation in Colorado. Legal counsel advising AI clients on Illinois-nexus transactions must account for AISMA requirements in due diligence, licensing, and contractual risk allocations.
AISMA includes a safe-harbour for developers who have conducted audits in compliance with specified standards and reported safety incidents in good faith. The Act conditions enforcement on a right to cure and vests the Illinois Attorney General with primary enforcement authority. Open questions include the exact capability thresholds that will trigger coverage, which the Act delegates to agency rulemaking.
