The rules

If a UK ban on social media platforms offering accounts to users under age 16 is in effect after Issuance and before Jan 1, 2027, then the market resolves to Yes.

The full rules are on the market's page at Kalshi.

Reading the odds

A prediction market trades contracts that pay $1 if something happens. Its price is the market's chance: a contract at 62¢ means traders give it 62%. Each number here is the midpoint between the best bid and offer, or the last trade when they are more than ten cents apart.

For a question with many answers (who wins, which range a number lands in), the chances are scaled to add up to 100%. A price ladder ("above 4.25%, above 4.50% ...") gives a whole distribution: its median is where traders see an even chance either way.

Kalshi is a U.S. exchange regulated by the CFTC; its money is counted in contracts, shown here as dollars at their price. Polymarket counts dollars. ForecastEx is Interactive Brokers' exchange, regulated by the CFTC; its contracts too are shown as dollars at their price. Crypto.com lists its markets on Crypto.com | Derivatives North America, a U.S. exchange regulated by the CFTC; it reports the dollars traded. Where more than one asks the same question, each is shown, never averaged.
