Dallas Wings vs. Chicago Sky

Market context

The Dallas Wings beat the Chicago Sky 99-89 in Chicago on 20 May, so the market’s 100% YES price has already been settled by the result rather than by any live uncertainty. Dallas were ahead at the break and closed out a game that featured a strong scoring night from Paige Bueckers and Arike Ogunbowale, while Chicago’s first-half start did not hold up after the interval. Recent form in this pairing therefore points to Dallas having the edge, but that is now only useful as context for future matchups, not for this one.

For traders looking at comparable cases, the main lesson is that a full-game WNBA result can override pre-match assumptions quickly when one side’s shot creation is cleaner and the other’s defence cannot sustain it for four quarters. ESPN’s game summary and full highlights both confirm the 99-89 final, which removes any need to model postponement or cancellation scenarios unless the contest had not completed. The key catalysts to watch in similar spots are injury reports, late roster changes and any schedule compression that might affect a rematch, but none alter this settled outcome.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.

FAQ

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
