This market will resolve to the temperature range that contains the lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 5 Jul '26. The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Tokyo Haneda Airport Station, available here: https://www.wunderground.com/history/daily/jp/tokyo/RJTT. 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.

Prediction market odds often diverge from traditional weather analyst forecasts because they incorporate real-time trading by informed participants responding to the latest data. While meteorologists publish official temperature predictions based on atmospheric models, this market aggregates the views of traders who may have access to specialized forecasts or different interpretive frameworks. The odds here reflect a crowd-sourced probability that can shift rapidly as new weather patterns develop or forecasts are updated. Comparing the market's implied probability to major weather services' confidence intervals reveals whether traders are pricing in more or less uncertainty than professional models suggest for Tokyo's July 5 low temperature.
This market resolves around Jul 5, 2026, once the lowest temperature recorded in Tokyo on July 5 is verifiable from credible public sources. The outcome is determined by comparing actual meteorological data against the prediction thresholds embedded in the market's contract. Traders' positions settle based on whether the real-world temperature aligns with their chosen outcome. Resolution typically occurs within hours of the close of the trading day, after official temperature readings are published and confirmed. The market's integrity depends on transparent, independently verifiable data that all participants can access equally.
Major weather pattern shifts, updated seasonal forecasts, and tropical storm activity could significantly move odds in this market. If meteorological agencies revise their July 5 temperature predictions upward or downward, traders typically react by repricing shares. Unusual atmospheric conditions—such as unexpected heat waves or cooler-than-normal air masses moving toward Japan—often trigger sharp trading activity. Media coverage of extreme weather events in the region can also influence trader sentiment. Additionally, as July 5 approaches, real-time weather updates and short-range forecasts become more precise, allowing traders to refine their positions. Each new data point about atmospheric pressure, humidity, and wind patterns provides fresh information that can reshape market expectations for Tokyo's minimum temperature.
