Illinois Enacts Artificial Intelligence Safety Measures Act

Illinois enacted the Artificial Intelligence Safety Measures Act on 6 July 2026, imposing governance, transparency, audit, and incident-reporting obligations on developers of frontier AI models with annual revenues exceeding $500 million, effective 1 January 2027 with substantive compliance required by 2028. The Act mandates risk frameworks, public transparency reports, annual third-party audits, 72-hour incident reporting (24 hours for imminent death/injury risks), and establishes penalties up to $3 million for violations. If you're building frontier models and operating in Illinois (or the US market), you now face $500m revenue thresholds, mandatory safety frameworks, third-party audits, and 24-72 hour incident reporting starting January 2027. That's a playbook; expect other states to copy it within months.
