France's Parliament has passed a bill banning social media access for children under 15, making it the first European country to do so. The legislation, which still requires approval from France's Constitutional Council before it becomes law, was passed on July 21, 2026 following committee approval the previous day (Reuters, The Guardian, Engadget).

President Emmanuel Macron has called for the law to be enforced by the start of the school year in September 2026. Macron has also advocated for the measure at the European Union level, pushing for broader adoption across member states (Reuters, Engadget).

ARCOM, France's digital communications regulator, will enforce the ban once it is in place. The mechanism involves a blacklist of social networks barred to under-15s, a device adopted by the French Senate that received approval ("feu vert") from the European Commission on July 8, 2026 (Engadget, Sénat). The European Commission's sign-off was a necessary precondition, since the blacklist mechanism needed to clear EU state aid and internal market rules before France could implement it.

The bill will be introduced in two stages, according to The Guardian (The Guardian). The legislation was introduced by MP Laure Miller and several of her colleagues, and is officially registered as proposition de loi n° 2610 in the 17th legislature of the French National Assembly (Assemblée Nationale, Assemblée Nationale). The Senate modified the bill during the legislative process (Assemblée Nationale).

This legislation arrives against a layered French legal backdrop. LOI n° 2023-566, enacted on July 7, 2023, established the framework for "majorité numérique" (digital majority) and combating online hate, setting the threshold at 15. The law, commonly known as the "loi Marcangeli," was never actually applied in practice, as acknowledged during a French Senate session on March 31, 2026 (Sénat). That session specifically discussed the digital majority framework and its non-application, underscoring the gap between legislative intent and enforcement that the new bill aims to close.

The 2023 law has since been amended twice. LOI n° 2024-449 of May 21, 2024 modified the digital majority law, including changes to its Article 7, with certain provisions carrying staggered effective dates including February 13, 2026 and July 18, 2026 (Légifrance). A separate law, LOI n° 2024-364 of April 22, 2024, also cross-references the digital majority framework, with a version effective July 12, 2026 (Légifrance). A related bill (n° 2718) was also proposed in the 17th legislature to explicitly prohibit digital mechanisms that promote addictive use among minors (Assemblée Nationale).

France is not alone in this regulatory direction. Australia passed a social media ban for children in 2024, establishing a precedent that other democracies are now building on (Engadget).

The broader context here is a regulatory architecture still finding its footing. France has spent three years passing digital-majority legislation that never took effect, amending it twice, securing EU-level clearance for an enforcement mechanism, and now passing a standalone ban that itself faces Constitutional Council review before it can be operationalized. Each step has narrowed the gap between legislative intent and practical enforcement, but the gap has not fully closed. The Constitutional Council review is the next gate, and ARCOM's enforcement design is the one after that.

For platforms operating in the EU, the implications are concrete. A French blacklist mechanism with European Commission approval establishes a template that other member states could replicate under existing internal market rules, particularly if Macron's push for EU-level adoption gains traction. The two-stage introduction gives platforms limited time to build compliance frameworks, and the enforcement role assigned to ARCOM rather than to platforms themselves shifts the regulatory model from self-regulation to direct state oversight.

Whether the September 2026 target holds depends on the Constitutional Council's timeline and on ARCOM's readiness to operationalize the blacklist. The loi Marcangeli's non-application is a cautionary precedent: passing a digital majority law is one thing, making it stick is another.
