Market context
The Las Vegas Aces defeated the Toronto Tempo 109–83 in their Monday night WNBA matchup at Toronto, with A’ja Wilson scoring 26 points and Jackie Young adding a season-high 24 points alongside 12 assists[2]. This result confirms the 100% YES crowd-implied probability for the Aces winning this specific game, as the contest has already concluded with a decisive victory[2][8].
Historically, WNBA markets resolving to 100% probability after a game’s completion reflect the standard settlement protocol where outcomes are determined by final score including overtime, eliminating uncertainty once the match ends[1]. Comparable cases in sports prediction markets show that once a game finishes with a clear winner, liquidity evaporates and the market locks in the resolved outcome, mirroring how this Aces–Tempo market now stands as a settled fact rather than a live trade[1][2].
Traders should monitor official WNBA settlement confirmations and any potential post-game appeals, though no such dependencies are currently active for this completed fixture[2]. The primary catalyst was the game’s final score, which is now fixed, and the settlement window ending 2026-07-21 serves only as the administrative deadline for formal resolution rather than a variable affecting the outcome[1][2]. No further announcements, schedule changes, or key absences will alter the result, as the Aces’ victory is already recorded in the official gametracker[2][8].

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
