This market will resolve to the temperature range that contains the highest temperature recorded at the Marcos A. Gelabert Intl Airport Station in degrees Celsius on 4 Jul '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 Marcos A. Gelabert Intl Airport Station, available here: https://www.wunderground.com/history/daily/pa/panama-city/MPMG. 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, media attention, and emerging data rather than relying solely on meteorological models. While meteorologists publish deterministic or probabilistic forecasts based on atmospheric science, this market aggregates the financial incentives of traders who profit from accurate predictions. Comparing the odds here to published forecasts from the National Weather Service or regional meteorological agencies can reveal whether traders are pricing in more optimistic or pessimistic temperature scenarios than official models suggest. This divergence frequently signals where market participants see model uncertainty or underappreciated risk.
On Polymarket, this market is priced through an automated market maker (AMM) mechanism where traders buy and sell outcome shares, and the contract price adjusts dynamically based on supply and demand. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades between 0 and 100 cents, with the price reflecting the implied probability that outcome will occur. As traders accumulate positions ahead of July 4, the relative prices of competing temperature ranges shift to reflect updated consensus. Liquidity and trading volume directly influence how quickly prices respond to new weather data or forecasts.
This market resolves around Jul 4, 2026, once July 4 has passed and the highest temperature in Panama City can be verified from credible public sources. The outcome is determined by comparing reported temperature readings against the predefined outcome brackets or thresholds established at market creation. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless. Resolution typically occurs within hours or a day after the event, pending confirmation from reliable meteorological or official weather reporting.
Major weather pattern shifts, updated seasonal forecasts, or tropical storm activity in the Caribbean could significantly move odds in this market. Real-time atmospheric data releases, changes to long-range models, and historical temperature comparisons for July 4 in prior years all influence trader positioning. Media coverage of heat waves or unusual weather systems affecting Central America may trigger rapid repricing. Additionally, as July 4 approaches, actual daily high temperatures in the days leading up to the event provide concrete signals that traders use to refine their predictions, often causing sharp moves in the final 48 hours.
