The UK has proposed a blanket social media ban for users under 16, covering virtually every major platform — TikTok, Instagram (Meta), YouTube (Alphabet), Facebook (Meta), Snapchat (Snap), and X. The policy mirrors legislation recently passed in Australia and signals a hardening regulatory posture toward Big Tech on child safety grounds. While enforcement mechanisms and a legislative timeline remain unclear, the breadth of platforms named leaves little room for carve-outs.

The second-order question is whether this is a UK-only event or the leading edge of coordinated Western regulation targeting teenage users — a segment that anchors long-term user growth and advertiser demographics for Snap and Meta in particular. Snap is arguably most exposed given its core identity as a youth-first platform; Meta and Alphabet have more diversified revenue bases to absorb the hit. Watch for the EU to reference this bill in ongoing Digital Services Act enforcement and for Snap's next earnings call for any updated DAU guidance in UK/European markets.
