What happened
On June 4, 2026, Representatives Jay Obernolte (R-CA) and Lori Trahan (D-MA) released a bipartisan discussion draft of the Great American Artificial Intelligence Act (GAAIA). The draft proposes: (1) a three-year moratorium preempting state laws specifically regulating AI model *development* (while preserving state authority over deployment/use); (2) codification of a Center for AI Standards and Innovation (CASI) at NIST, with a NIST-housed auditor function carrying up to $1 million-per-day enforcement penalties; (3) mandatory pre-deployment risk-management plans for frontier AI developers; (4) transparency requirements for frontier models; and (5) a cybersecurity and workforce impact tracking mandate. On June 25–26, the House Science, Space and Technology Committee advanced multiple bills incorporating GAAIA priorities in a markup session.
Why it matters
The GAAIA is the most comprehensive federal AI legislative proposal to date and, if enacted, would create a single national compliance regime for frontier AI development — displacing Colorado's ADMT Act, California's developing frameworks, and other state laws at the developer level. The three-year state preemption clause is the most contested element and would significantly reshape the compliance landscape for AI developers operating across states. The $1M/day enforcement mechanism signals Congress is prepared to give teeth to federal AI oversight.
Action needed
AI developers should submit comments during the industry input period. Compliance teams should model scenarios under the proposed three-year state preemption to assess how GAAIA would interact with existing state-level obligations. Track House Science Committee markup progress for committee-approved bills that may be fast-tracked.
