    Fast-moving patchwork of binding state laws under federal preemption pressure

    Regulatory posture

    With Washington declining to legislate, states became America's de facto AI regulators: Colorado's duty-of-care regime, Texas's TRAIGA, California's frontier-model transparency law (SB 53) and training-data disclosure rules all took effect in 2026. EO 14365's litigation task force now contests this patchwork, making US compliance a two-front battlefield.
