Description

This event group tracks precipitation levels in Seattle during July 2026, with markets structured around specific precipitation thresholds.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: The markets differ in both the month being measured (July vs. August) and the resolution thresholds (ranges vs. strict greater-than values).Hero tip: Do not hedge positions across these platforms as they measure different months and use incompatible resolution thresholds.

Critical divergence points:

  • Polymarket: Resolves based on total precipitation in Seattle for July 2026, using NOAA data. Markets are structured as ranges (e.g., <0.5 inches, 0.5-1 inches, etc.).
  • Kalshi: Resolves based on total precipitation in Seattle for August 2026, using CLISEA data. Markets resolve to Yes if precipitation strictly exceeds a threshold (e.g., >1 inch, >2 inches, etc.).
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.

Polymarket

This market will resolve according to the total precipitation in inches in Seattle between July 1 and July 31, 2026, 11:59PM ET according to the National Oceanic and Atmospheric Administration (NOAA). The resolution source for this market will be NOAA, specifically the figure for July 2026 when the "Monthly summarized data" for "Seattle City Area" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=sew link once that figure is finalized for the whole month of July 2026. If the reported data falls exactly between two brackets, this market will resolve to the higher bracket. The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.

Kalshi

The event determines if total precipitation at CLISEA in Seattle during August 2026 exceeds specified thresholds (1, 2, 3, 4, 5, or 6 inches). All markets resolve based on the same underlying data source: the official NWS Climatological Report (Daily) for Seattle-Tacoma, WA, accessed via the provided URL. Traders must use the latest reported data, noting that preliminary NWS figures may contain rounding or conversion nuances. While external weather services may offer guidance, only the designated NWS report serves as the definitive source for resolution. Each threshold represents a distinct Yes/No outcome, with higher thresholds requiring progressively more rainfall to settle positively.
