The rules

This market will resolve to "Yes" if at least 50 flights depart from Riyadh's King Khalid International Airport (RUH) within a single calendar day in Riyadh local time (Arabia Standard Time, AST), between the date of market creation and the specified date. Otherwise, this market will resolve to "No". Departures will be evaluated as displayed by FlightAware on its King Khalid Int'l Airport (Riyadh) RUH airport page (https://www.flightaware.com/live/airport/OERK) and the corresponding departures page (https://www.flightaware.com/live/airport/OERK/departures). Only confirmed departures, displayed with an actual departure time, qualify; scheduled departures do not qualify. Only departures occur

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

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.

Prefer betting odds? Switch to American (+150) or decimal (2.50) odds at the top of the page.
