The Evidence Gap: Why Courts Can't Balance State AI Regulation

TLDR

• Courts lack empirical data to evaluate whether 1,500+ state AI bills unconstitutionally burden interstate commerce under the dormant Commerce Clause.

Key Takeaways

• Over 1,500 state AI bills were introduced by March 2026; 1,000+ came in 2025 alone, creating a patchwork compliance burden.
• xAI filed a federal lawsuit challenging Colorado’s AI Act specifically on dormant Commerce Clause grounds.
• Pike balancing requires courts to weigh a law’s burden on interstate commerce against local benefits, but no standard evidentiary framework exists for AI.
• Authors propose pre-enactment evidentiary statements, post-enactment reviews, and anonymous company compliance cost disclosures to build the record.
• Federal OIRA analysis of state AI laws and judicial education on cost-benefit methodology are among eight proposed fixes.

Why It Matters

• Without a structured evidence record, courts default to minimal data, making Pike challenges unpredictable and easy for states to survive regardless of actual burden.
• Better evidentiary requirements would force legislators to defend regulatory choices explicitly, improving both law design and constitutional scrutiny.
• The xAI v. Colorado lawsuit is the first live test of this doctrine against state AI law, setting precedent for how courts handle a growing docket.
