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 5, 2026 snapshot · 61/100 · Solid Signal
| Component | Points | What the data says |
|---|---|---|
| Liquidity | 30/30 | $1M in comparable USD-reported volume. Log-scaled: $1k scores 0, while $1M+ maxes the component. |
| 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 | 15/15 | 19 tracked markets on this event — more side markets and strikes mean more angles pricing the same story. |
| Track-record depth | 8/15 | 5 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.

The prediction market prices Brazil Presidential Election First Round: 3rd Place at 52% implied probability on Polymarket as of Saturday, September 5. Here is the dated market read.
What the prediction market is pricing
Across 19 tracked market rows, Polymarket reports $1M in venue-native event volume. Augusto Cury leads at 52%, a narrow favorite, ahead of Renan Santos at 26%. It currently trades on Polymarket; any related listing on another venue remains separate until identity is confirmed.
How geopolitical markets like this resolve
Geopolitical markets resolve on an international event — a ceasefire, a summit, a transit count, a diplomatic outcome — by a deadline. The price is a real-money read on an uncertain, fast-moving situation.
What could move it
Official statements, on-the-ground developments, sanctions, and diplomatic breakthroughs or breakdowns drive the moves. Because real money is on the line, the price reprices quickly around these catalysts — which is what makes 52% a live estimate rather than a settled call.
Reading the number
A contract at 52¢ implies a 52% 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 Saturday, September 5; odds move continuously, so open Polymarket for the current line.
