What happened
On July 6, 2026, Illinois Governor JB Pritzker signed SB 315, the Artificial Intelligence Safety Measures Act, into law. The statute requires developers of the largest 'frontier' AI models (e.g., systems comparable to ChatGPT, Claude) to publish and annually update a framework addressing catastrophic-risk assessment and mitigation, undergo the nation's first mandatory independent third-party safety audits, report critical safety incidents within 72 hours (24 hours if imminent risk of death/serious injury) to the Illinois Emergency Management Agency and Attorney General, and establish whistleblower protections for employees. Catastrophic events are defined as causing 50+ deaths or $1B+ in damage. Penalties reach $3 million per repeat violation. The law takes effect January 1, 2027.
Why it matters
This is the third state (after New York's RAISE Act and California's SB 53) to enact binding frontier-AI safety legislation, and the first anywhere to mandate independent third-party audits of frontier developers' safety practices — a template advocates expect other states and Congress to follow. It creates enforceable, statutory catastrophic-risk governance obligations (not just guidance) directly binding major AI labs operating in or serving Illinois.
Action needed
Frontier AI developers must prepare frontier-safety frameworks, third-party audit arrangements, and 72-hour incident-reporting mechanisms ahead of the January 1, 2027 effective date.
