# Illinois Governor Pritzker signs landmark AI Safety Measures Act into law

> Illinois Governor JB Pritzker has signed the AI Safety Measures Act, which the state is billing as the most comprehensive set of AI rules at the state level in the country. The law requires developers of advanced models to identify potential catastrophic risk, disclose their safety frameworks and the steps they take to reduce harm, and report major incidents to the state within 72 hours, or within 24 hours when there is an imminent threat of death or serious injury. Signed on July 6, the measure is modeled on similar efforts in California and New York, and it deepens a growing patchwork of state-level AI regulation taking shape while federal rules remain unsettled. For AI companies, the practical effect is more mandatory transparency and faster incident reporting, and another jurisdiction whose requirements they will have to meet. It also sharpens a brewing fight over whether states or Washington should set the terms, a tension the FTC is now wading into directly.
