Definition
A legal mechanism by which a federal US law overrides and displaces state laws covering the same subject, so that only the federal rules apply. In the AI context, several 2026 federal proposals — including the GAAIA — would prevent states like California, Colorado, and Connecticut from enforcing their own AI regulations while a national framework is established. Preemption resolves regulatory conflicts but can also eliminate stricter state-level consumer protections.
Why it matters
Boards and legal teams need to track whether federal preemption passes, because it would invalidate compliance programmes built around specific state AI laws — and could simultaneously remove the safety guardrails those laws provide to consumers.
