How It Works
From model runs to market edge
Three steps. No guesswork. Pure probability.
01
Ensemble Modeling
We ingest GEFS, ECMWF, HRRR, NBM, NDFD, and 6 additional forecast models, blending them into a calibrated probability distribution for each city's high temperature.
02
Fair Value Computation
Our engine integrates the ensemble distribution over each Kalshi market bucket using Gaussian quadrature, producing a precise probability estimate for every strike price.
03
Edge Detection
When market price diverges from fair value by 12¢ or more, the system flags the opportunity and — for Elite subscribers — executes Kelly-sized orders automatically.
