Illinois Governor Signs AI Accountability Bill Targeting Major AI Companies

Summary

Illinois Governor JB Pritzker signed Senate Bill 315 on Monday, landmark legislation requiring artificial intelligence developers to establish transparency frameworks and submit to third-party audits. The bill, which passed nearly unanimously in both chambers of the Illinois legislature, mandates that AI companies report safety incidents within 24 hours, implement measures to limit catastrophic risks, and maintain whistleblower protections. Violations can result in fines up to $3 million per infraction. The legislation targets the largest AI companies—those with $500 million or more in revenue and massive computing capabilities—effectively focusing on organizations like OpenAI and Anthropic, both of which supported the bill throughout its development.

The bill was modeled after similar 2025 legislation in New York and California, as lawmakers seek to establish a national standard for AI accountability in the absence of federal regulation. Governor Pritzker emphasized that while AI represents "the single most significant technological innovation of the modern age," the lack of federal oversight and the rush for profits among tech leaders have created serious risks to public interest. The legislation reflects rare bipartisan consensus, with members of both parties united in preventing with AI the regulatory failures that occurred with social media.
