Illinois enacts Artificial Intelligence Safety Measures Act

Illinois enacts SB 315, the Artificial Intelligence Safety Measures Act, establishing mandatory third-party audits, transparency reporting and critical incident disclosure for large frontier AI developers, effective 1 January 2027. The law applies to any company with operational touchpoints in Illinois and requires frontier AI frameworks, annual disclosures and independent audits. If you build frontier models and have any commercial footprint in Illinois, you now have six months to architect an audit programme and safety disclosure process before 1 January 2027. This is the first state law to mandate third-party audits of AI systems—compliance is not optional, and audit design will compound if you operate across multiple states.
