The resolution source for this market will be information from Wunderground, specifically the highest 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 forecasts because they incorporate real-time trader behavior and financial incentives. While meteorologists rely on atmospheric models and historical data, this market aggregates the collective judgment of participants betting on the actual outcome. Comparing current implied probabilities to official forecasts from Japan's Meteorological Agency or other analysts can reveal where traders see value or disagreement. Markets tend to update faster than seasonal forecasts when new data emerges, making them a dynamic alternative to static analyst predictions.
This market resolves around Jun 25, 2026, once the highest temperature recorded in Tokyo for June 25 is finalized and verifiable from credible public sources. The outcome is determined by official meteorological data, typically confirmed by Japan's Meteorological Agency or equivalent authoritative weather records. Resolution occurs after the trading window closes and the actual temperature is confirmed, allowing the platform to settle all positions based on which outcome bracket the final reading falls into.
Weather model updates and seasonal forecasts are primary drivers of price movement in this market. Major atmospheric patterns, tropical systems, or heat waves affecting East Asia could shift trader expectations significantly. Real-time weather alerts, changes in long-range forecasts, and historical temperature comparisons for that date will influence positioning. As June 25 approaches, intraday weather reports and satellite imagery become increasingly important, potentially triggering sharp repricing as the event date nears and uncertainty narrows.
