Two Ways to Find Edge

One for same-day certainty, one for multi-day probability. Both backed by professional-grade NOAA data that most traders never see.

SAME-DAY

METAR Lock

After 2 PM ET

~88%WIN RATEMETAR Lock

The thermometer already shows the answer. Real-time METAR airport observations tell you the daily high before the market adjusts. Enter near-certainty contracts before the market reprices.

Example

When the airport sensor says 82°F at 2:47 PM and the market asks "Will the high exceed 80°F?" at $0.72 — that's free money.

GFS Ensemble

Pre-Event Analysis

~65%WIN RATEGFS Ensemble

When 83% of model runs agree but Kalshi prices it at 15%, you have edge. The 31-member GFS ensemble gives you probability distributions that the market hasn't fully absorbed.

Example

27 of 31 ensemble members say Denver will exceed 85°F. Kalshi YES is at $0.18. That's a 56% edge.
