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 21, 2026 snapshot · 26/100 · Thin Signal
| Component | Points | What the data says |
|---|---|---|
| Liquidity | 10/30 | 18.5K venue-reported contracts. Contract counts are not converted to dollars, so this component remains at the documented neutral 10/30. |
| 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 | 6/15 | 4 tracked markets on this event — more side markets and strikes mean more angles pricing the same story. |
| Track-record depth | 2/15 | 1 attributable day 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.

How political markets like this resolve
Political markets resolve on an official outcome — a vote, an appointment, a signed order, a court ruling — by a stated deadline. The price is the crowd’s real-money read on whether it actually happens, not a pundit’s guess.
What could move it
Polling, legislative calendars, court dockets, primary results, and official announcements are the catalysts that reprice political markets. 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.
