Market context

The upcoming WNBA matchup between the Washington Mystics and the New York Liberty, played on June 19 at Barclays Centre in Brooklyn, has already concluded with a decisive 86–64 victory for the Liberty [4][7]. This result confirms the market’s 100% YES resolution to “New York Liberty”, as the home team covered the spread by 22 points and secured their seventh consecutive win [1][7].

Historically, such 100% implied probabilities in prediction markets for completed games reflect post-settlement certainty rather than pre-game forecasting, a pattern seen when sportsbooks adjust lines after final scores are confirmed [2][3]. In comparable cases, divergence between live sportsbook odds (which showed the Liberty at –800 moneyline) and prediction-market implied probability (78% prior to game time) highlights how traders priced in the Liberty’s strong form before the result was official [1][2].

Traders should monitor official WNBA announcements regarding schedule changes or player availability for future fixtures, as these dependencies can shift odds in upcoming contracts [5]. Recent coverage from ESPN confirms the Liberty’s dominant performance, with Jonquel Jones contributing 20 points and four steals in the win [1][7]. No further action is needed for this settled market, but the data offers a clear benchmark for evaluating similar sports contracts.

Methodology

We track Washington Mystics vs. New York Liberty on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
