Polymarket
This market will resolve to the temperature range that contains the lowest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 10 Jun '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 LaGuardia Airport Station, available here: https://www.wunderground.com/history/daily/us/ny/new-york-city/KLGA. 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 Fahrenheit (eg, 21°F). 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 on Polymarket reflect real-time trader conviction and aggregate information, often diverging from traditional meteorological forecasts. While weather analysts issue point estimates and confidence intervals based on atmospheric models, prediction markets price outcomes based on collective belief and financial incentives. The market odds tend to incorporate late-breaking weather data, ensemble model shifts, and trader expertise faster than static forecasts update. Comparing the leading market outcome to National Weather Service or private meteorology firm predictions reveals whether traders are pricing in tail risks or consensus scenarios that official forecasts may underweight or overlook.
The market resolves on Jun 10, 2026, after the lowest temperature in New York City on June 10 has been recorded and verified. Resolution hinges on identifying which temperature range bracket the actual daily low falls into. Official temperature data from a designated weather station or aggregated source determines the winning outcome contract. Traders holding positions in the correct range receive their payout, while incorrect positions expire worthless. The resolution process is automated once the reference data is confirmed, ensuring transparent and timely settlement for all participants.
Major weather pattern shifts, updated seasonal forecasts, and atmospheric pressure systems tracking toward the Northeast can significantly move market odds. Tropical systems, cold fronts, or high-pressure ridges developing weeks in advance will influence trader expectations and repricing. As June 10 approaches, real-time model consensus from the GFS, European, and NAM models becomes more precise, often triggering sharp price adjustments. Anomalous warming or cooling trends in late May and early June also signal market moves. Breaking news of volcanic activity, solar cycles, or El Niño updates may shift long-range conviction. Day-of-event morning model runs typically produce final volatility spikes as traders lock in positions before the market resolves.
