W.E.T. Score
How much signal is behind this number?
The W.E.T. Score grades the evidence, not the outcome. Five inputs — comparable volume evidence, news corroboration, cross-venue verification, market coverage, and track-record depth — scored against how much verifiable signal sits behind the headline probability.
Scored from the September 2, 2026 snapshot · 20/100 · Thin Signal
| Component | Points | What the data says |
|---|---|---|
| Liquidity | 0/30 | No positive venue-reported volume was available at snapshot time. |
| News corroboration | 0/20 | No wire headlines matched this event at snapshot time — the price stands alone. |
| Cross-venue verification | 8/20 | No canonical exact-match pair is available for this snapshot. Related listings are not compared, so this component remains at the documented neutral 8/20. |
| Market coverage | 12/15 | 8 tracked markets on this event — more side markets and strikes mean more angles pricing the same story. |
| Track-record depth | 0/15 | 0 attributable days tied to one venue, favorite, and listing key. Legacy unkeyed points earn no depth credit. |
The W.E.T. Score measures evidence quality — comparable volume, verified agreement, coverage, and corroboration behind a price. Venue-reported contract counts are never treated as dollars. It is not a prediction of the outcome, not a rating of whether the favorite wins, and not trading advice: a Thin Signal market can still resolve YES, and a Prime Signal market can still resolve NO. Full weighting and worked examples in the methodology.

How sports markets like this settle
Sports markets resolve on the game itself — a final result, a score line, a player total. The implied probability is what traders are collectively paying for each outcome, repriced live as lineups, injuries, and in-game events land.
What could move it
Team news and injuries, roster and lineup changes, weather for outdoor games, and the way the line drifts from open to close as sharp money arrives are what move these prices. Because real money is on the line, the price reprices quickly around these catalysts — which is what makes 34% a live estimate rather than a settled call.
Reading the number
A contract at 34¢ implies a 34% chance the market resolves YES: a dated venue observation of implied probability, not a forecast or a tip from W.E.T. The figure above is a snapshot as of Wednesday, September 2; odds move continuously, so open Kalshi for the current line.
