This market will resolve to the temperature range that contains the highest temperature recorded at the King Abdulaziz International Airport Station in degrees Celsius on 1 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the King Abdulaziz International Airport Station, available here: https://www.wunderground.com/history/daily/sa/jeddah/OEJN. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Polymarket, this event is priced as a set of outcome shares, each representing a specific temperature range or threshold. Traders buy and sell these shares, with prices reflecting the probability of each outcome occurring. The market uses an automated market maker mechanism to determine share prices based on supply and demand. As traders adjust positions ahead of Jun 1, 2026, prices shift to reflect new information about weather patterns, seasonal trends, and atmospheric conditions affecting Jeddah.
The market resolves on Jun 1, 2026, after the highest temperature in Jeddah on June 1 has been recorded and verified. Resolution depends on official temperature data from a designated weather source or meteorological authority for Jeddah. The actual peak temperature observed on that date determines which outcome shares are correct. Traders holding shares in the winning outcome receive their payout once the final temperature is confirmed and the market settles.
Several factors can shift odds for Jeddah's June 1 temperature. Major weather pattern changes, such as shifts in monsoon activity or unusual pressure systems, can alter forecasts significantly. Updated seasonal climate models and long-range weather outlooks will influence trader positioning. Real-time atmospheric data, including sea surface temperatures and humidity patterns in the Arabian Peninsula, may trigger repricing. Additionally, historical anomalies or extreme heat events in the region can prompt traders to adjust expectations. As June 1 approaches, short-range forecasts become more precise and typically drive larger price movements.
