What Just Happened

The Illinois House passed SB 315, the Artificial Intelligence Safety Measures Act, on May 27 by a vote of 110-0. The Senate had already passed it 52-5 on May 21, according to Capitol News Illinois.

Governor JB Pritzker posted on X the same day: "Illinois is leading the nation in holding Big Tech accountable. I look forward to signing SB 315."

What the Bill Actually Does

Three concrete requirements:

First: Frontier AI companies — think OpenAI, Anthropic, Google DeepMind — must create, publish, and annually update a framework addressing catastrophic risk assessment, cybersecurity, internal governance, and third-party evaluations.

Second: Annual independent third-party audits of safety practices. According to Wired, likely candidates to perform those audits include the Big Four accounting firms — Deloitte, EY, KPMG, and PwC — or members of the AI Evaluator Forum, a coalition that includes research organizations METR, Transluce, and Averi.

Third: Whistleblower protections for employees at AI companies who report safety violations.

Why This Is Different From California and New York

California's SB 53 and New York's RAISE Act both require AI companies to publish safety information and report incidents. Illinois, according to the Transparency Coalition, goes one step further by requiring an outside auditor to verify companies are actually doing what they claim.

Scott Wisor, policy director at Secure AI Project, told Wired: "We're in a situation where the AI companies grade their own homework. Should SB 315 become law, Illinois would require an independent auditor to check whether the AI labs in fact adhere to their safety commitments."

Before this, every safety claim from OpenAI or Anthropic was self-reported with zero external verification.

Who's For It, Who's Against It

OpenAI and Anthropic publicly support the bill. OpenAI spokesperson Jamie Radice told NBC News: "The Illinois General Assembly has shown real bipartisan leadership in advancing SB 315 and developing a thoughtful framework for frontier AI safety."

These are the exact companies that would face the most scrutiny under this law.

A trade organization representing other AI companies has opposed it, according to NBC News. That organization was NOT named in any of the four source reports. Readers deserve to know who's lobbying against this.

Google, xAI, and Meta did not respond to NBC News' requests for comment.

What Mainstream Coverage Is Missing

Most outlets are framing this as a progressive tech regulation win and stopping there.

Congress has passed zero meaningful AI safety legislation. California, New York, and now Illinois are writing the de facto national standard through state law.

House sponsor Rep. Daniel Didech, D-Buffalo Grove, told NBC News directly: state legislatures are "acting as a testing ground for any federal laws that might come in the future."

OpenAI's chief of global affairs Chris Lehane told Wired last week that OpenAI's AI policy is now oriented around passing a series of state laws like this one. The company has decided federal action isn't coming and is working to shape the state-by-state patchwork instead.

The Fiscal and Accountability Questions

Who pays for these audits? The bill places the requirement on the companies — not taxpayers.

But the enforcement mechanism isn't spelled out clearly in any of the source reports. What happens when an auditor flags a violation? What are the penalties? Who in Illinois state government has jurisdiction to act on audit findings?

Representatives Didech and Senator Mary Edly-Allen, D-Lake County, should provide clear answers on enforcement before Pritzker signs the bill.

What Comes Next

A 110-0 House vote on anything in 2026 is almost unheard of. That bipartisan margin suggests even lawmakers skeptical of regulation saw no good argument for letting the most powerful technology in human history run entirely on the honor system.

The AI companies are already worth trillions and can afford audits. If their safety practices are as solid as they claim, independent verification should present no obstacle.

Congress has not acted. Illinois just did.
