About this market

Live prediction market odds for "UK social media ban in effect by…?". Before Aug 1, 2027 leads at 71%. Next is Yes at 68%. $11K has traded across 6 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 1, 2027.

On June 15, 2026, Prime Minister Keir Starmer announced the UK government’s intention to ban children under the age of 16 from accessing social media services. This market will resolve to "Yes" if a ban on the use of social media by children under the age of 16 within the United Kingdom takes effect by the listed date, 11:59 PM ET. Otherwise, this market will resolve to "No". A ban will qualify when legislation or a mandate from Ofcom or another UK government regulator is effectively imposed on any group of social media platforms, requiring them to prevent children under the age of 16 from accessing their services, with regulatory penalties to be applied for noncompliance. A qualifying ban must be in effect against a group of social media platforms, defined as consumer-facing online services whose primary function is to view, share, create, and interact with user-generated content. An age restriction applying to online streaming (Netflix, Amazon Prime Video, Disney+, etc.) or pornographic (PornHub, OnlyFans, etc.) services will not qualify. For the purposes of this market, user-generated video and live-streaming websites like YouTube, Twitch, Kick, and Rumble will qualify as social media platforms. To qualify, a ban must be effectively imposed on social media platforms by the listed date. The enactment of legislation or announcement of future policy without policy effectiveness will not qualify. While a qualifying ban may include exemptions for certain platforms and categories of social media, like direct messaging, a targeted age restriction policy applying to only one company or platform will not qualify. The primary resolution source for this market will be official information from the United Kingdom, including Ofcom (https://www.ofcom.org.uk), however a consensus of credible reporting will also be used.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
