Live consensus feed

Reading the run…

weathermarket.ai · the oracle

Eleven independent feeds every hour: two measured at the station, nine numerical models from national weather services.
Outliers excluded per metric, corroboration counted between the measured sources, and a verdict per metric on whether the hour can settle.
Every run hashed and anchored on a public ledger, so the number a market settles on can be checked after the fact.
Station records for the local calendar day with the raw METAR behind each extreme, and a 16-day forecast cut on station time.

weathermarket.io · this simulator

Turns each run into tradeable markets and parametric covers on 167 cities: hourly conditions, station-day extremes and index thresholds.
Prices from the forecast and the index history, shown next to the market so the edge is visible, with a living order book to trade against.
Lists next-day products only where the oracle's recent hours settle, and shows this feed on every market so the evidence is on the page before settlement.
Settles on the oracle's determination and nothing else, with the run, the anchor and the readings kept on the settled market.

Readings and verdict from the oracle's own run as served to a subscriber. The rule that turns eleven readings into one number is the oracle's and is not disclosed; what it decided is.Powered by Weather Data Market
