PredictPedia tracks a Polymarket event asking whether a social media ban for children under 16 will take effect in the United Kingdom. The event is titled "UK social media ban in effect by…?" and sits in the Politics category [1]. According to the market text, Prime Minister Keir Starmer announced on June 15, 2026 that the UK government intended to ban children under 16 from accessing social media services [1]. That announcement is a statement of intent. The contract is not about whether a policy was announced, but whether a ban is actually in effect by a listed date. The contract's rules define what counts. A ban qualifies when legislation, or a mandate from Ofcom or another UK government regulator, is effectively imposed on a group of social media platforms. The platforms must be required to prevent children under 16 from accessing their services, with regulatory penalties for noncompliance [1]. The rules describe social media platforms as consumer-facing online services whose primary function is to view, share, create, and interact with user-generated content. Streaming services and pornographic services are excluded. User-generated video and live-streaming sites such as YouTube, Twitch, Kick, and Rumble are expressly included [1]. A qualifying ban may contain exemptions for some platforms or categories, such as direct messaging, but a policy aimed at only one company or platform does not qualify [1]. The rules also distinguish between enactment and effect. Passing legislation or announcing future policy does not qualify unless the policy is effectively in force by the listed date [1]. The primary resolution source is official information from the United Kingdom, including Ofcom, and a consensus of credible reporting is also used [1]. The market snapshot shows two binary contracts under this event. One asks whether a UK ban takes effect by December 31, 2026, with a listed end time of 2027-01-01T04:59:00Z. The other asks whether a ban takes effect by June 30, 2027, with a listed end time of 2027-07-01T03:59:00Z [1]. Both listed times correspond to 11:59 PM ET on the named date, as the rules specify ET. The application records the observed prices separately.

Historical Context

Many countries and subdivisions have passed or proposed laws since 2023 requiring age verification for parts of the internet, including social media services. Most passed laws or bills rely on government-issued ID, a facial scan, or a credit card, often handled by third-party age verification providers [2]. Australia is one example. The Online Safety Amendment (Social Media Minimum Age) Act 2024 prohibits minors under 16 from holding accounts on certain social media platforms. Parliament passed it on 29 November 2024, and it imposes monetary penalties on companies that fail to take reasonable steps to prevent such accounts [3]. These sources describe earlier legislation elsewhere. They do not establish the status of any UK measure.
