Description

This market will resolve to the temperature range that contains the lowest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 12 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.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's resolution logic is internally contradictory (all conditions resolve to Yes, covering 100% of possible temperatures), making the market logically unresolvable. Additionally, Kalshi references June 11, 2026 while Polymarket references June 12, 2026. Data source also differs: Kalshi uses National Weather Service Climatological Report (Daily) for NYC; Polymarket uses Wunderground for LaGuardia Airport Station.Hero tip: Avoid trading Kalshi's market until the platform corrects its resolution logic. The current ruleset cannot distinguish between outcomes. Polymarket's market is structurally sound and uses a clear temperature-bucketing system. Confirm the intended event date (June 11 or June 12) and request Kalshi to redefine its conditions as mutually exclusive outcomes.

Critical divergence points:

  • Kalshi: All six temperature conditions (less than 66°F, 66-67°F, 68-69°F, 70-71°F, 72-73°F, greater than 73°F) resolve to Yes. This creates a logical tautology covering all possible temperatures. References June 11, 2026. Uses National Weather Service Climatological Report (Daily) as source.
  • Polymarket: Eleven mutually exclusive temperature ranges, each resolving to a specific outcome. References June 12, 2026. Uses Wunderground historical data for LaGuardia Airport Station, measured to whole degrees Fahrenheit. Resolution deferred until first data point of June 13 is published.
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Kalshi

Resolution is determined by the minimum temperature recorded at Central Park, New York on June 11, 2026, as reported in the National Weather Service's Climatological Report (Daily). The market divides the temperature range into five distinct bands: 65°F or below, 66-67°F, 68-69°F, 70-71°F, 72-73°F, and 74°F or above. Each temperature range corresponds to a specific market outcome. Official data must be obtained from the NWS Climatological Report accessed via the specified URL, selecting Central Park NY with Daily Climate Report. While preliminary data from other sources like AccuWeather or Google Weather may provide guidance, only the official NWS Climatological Report (Daily) determines final resolution. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect interpretation of borderline values.

Frequently asked questions

The dashboard aggregates real-time odds and trading activity for the lowest temperature in New York City on June 12 across Polymarket and Kalshi. It displays the consensus probability for each temperature band outcome, current bid-ask spreads, and cumulative trading volume to show where the market expects the low to fall. By tracking both platforms simultaneously, you can see how traders across different venues are pricing the same weather event and identify divergences that may signal arbitrage opportunities or shifting market sentiment.

Prediction market odds reflect real-money bets from traders and reflect collective expectations, while analyst forecasts come from meteorological models and expert judgment. Markets often incorporate broader information faster than traditional forecasts update. For the June 12 NYC low, comparing market-implied probabilities to National Weather Service or private weather service predictions can reveal where consensus diverges. Markets may price in tail risks or recent data shifts that models lag on, making side-by-side comparison valuable for understanding confidence levels across both approaches.

Major weather pattern shifts, updated seasonal forecasts, and real-time atmospheric data will drive market repricing. A developing high-pressure system could push temperatures higher, while an unexpected cold front or tropical system could lower them. Long-range model consensus updates in the days before June 12 typically trigger significant volume and price movement. Additionally, any unusual jet stream behavior or sudden shifts in the North Atlantic Oscillation could alter expectations. Traders should monitor extended forecasts and model guidance closely as the event date approaches.
