Maryland's Age-Appropriate Design Code Act, the Kids Code, has been in effect since October 1, 2024 and is being challenged in federal court by NetChoice, with a motion to dismiss denied in November 2025 and no injunction in place. Maryland has not enacted an adult content age verification law or an app store accountability law: bills on both topics stalled in committee in 2025 and 2026. No dedicated social media minor-access bill has advanced past introduction.
