# Illinois Governor Signs SB 315: Nation's Strongest AI Safety Law with Third-Party Audits

> Illinois has passed what its governor is calling the nation's strongest AI safety law, and the detail that stands out is enforcement teeth. SB 315 makes Illinois the first state to require independent, third-party audits of frontier AI systems, carried out by qualified experts with no financial conflicts. It applies to developers with more than $500 million in annual revenue running models above set compute thresholds, requires them to publish safety frameworks defining catastrophic risk, framed as 50 or more deaths or over $1 million in damage, and mandates incident reporting within 72 hours. The audit requirement is what separates this from the voluntary pledges labs have offered so far, because it puts an outside party with no stake in the outcome inside the process. The law takes effect January 1, 2027, which gives companies room to prepare and lobby. The bigger picture is jurisdictional weight: Illinois, California and New York together account for something like 40% of the US AI market, so a state-by-state patchwork with real audit rules could end up setting a national floor without any federal action.
