The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the London City Airport Station, available here: https://www.wunderground.com/history/daily/gb/london/EGLC. 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 reflect decentralized trader consensus and often incorporate the latest meteorological models and historical patterns faster than traditional analyst reports. While weather forecasters publish official outlooks through established channels, this market aggregates real-money bets from participants who stand to gain or lose based on accuracy. The two sources can diverge when traders spot emerging data or when consensus shifts ahead of formal forecast updates. Comparing the odds here to published forecasts from the UK Met Office or similar agencies reveals where the crowd sees edge or uncertainty that analysts may not yet have fully priced in.
This market resolves around Jul 1, 2026, once the lowest temperature recorded in London on July 1 is confirmed and verifiable from credible public sources. The outcome is determined by the actual meteorological reading from that date, compared against the threshold or range specified in the market's terms. Resolution typically occurs within hours or a day after the event, once official weather data is published and validated. Traders' positions settle based on whether the real-world temperature aligns with the outcome they backed.
Major weather pattern shifts, updated seasonal forecasts, and anomalies in atmospheric pressure systems can all drive significant price swings in this market. Heatwaves, cold fronts, or unusual jet-stream behavior reported by meteorologists will prompt traders to reassess odds. Climate data releases, historical temperature comparisons, and even major weather events elsewhere in Europe can influence expectations for London's conditions. As July 1 approaches, real-time forecasts become more precise, typically narrowing uncertainty and stabilizing prices closer to the actual outcome.
