W.E.T. Score
How much signal is behind this number?
The W.E.T. Score grades the evidence, not the outcome. Five measurable inputs — traded volume, news corroboration, cross-venue agreement, market coverage, and track-record depth — scored against how much verifiable signal sits behind the headline probability.
Scored from the August 2, 2026 snapshot · 44/100 · Developing Signal
| Component | Points | What the data says |
|---|---|---|
| Liquidity | 14/30 | $27.3K in matched volume across this event's markets. Log-scaled: thin books score near zero, $1M+ maxes the component. |
| News corroboration | 0/20 | No wire headlines matched this event at snapshot time — the price stands alone. |
| Cross-venue agreement | 16/20 | Kalshi 59% vs Polymarket 57% — a 2-pt gap. Two independent order books landing close is the strongest check a price can get. |
| 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 | 2/15 | 1 day of daily probability history on file. A longer tape shows how the price behaves, not just where it sits. |
The W.E.T. Score measures market microstructure — how much money, agreement, coverage, and corroboration sit behind a price. 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 59% a live estimate rather than a settled call.
