Chicago Sky vs. New York Liberty

Platform comparison

Market context

Polymarket’s contract is pricing **Chicago Sky at 28% YES** against the **New York Liberty** in tonight’s WNBA game, so the market is still leaning heavily towards a Liberty win rather than a Sky upset. On Polymarket, traders are buying and selling **USDC** positions on **Polygon**, with the outcome ultimately settled through the platform’s **conditional token** structure once the final score is confirmed, including overtime if needed.

That 28% level sits broadly in line with outside market views, though it is a touch firmer on Chicago than many sportsbook-style prices imply. Recent previews have had New York as a clear favourite, with moneyline estimates around a 75% win chance, and some models even more bullish on the Liberty, which suggests the contract is still leaving room for a Sky surprise rather than pricing it as a long shot. Comparable WNBA moneyline markets often move sharply when one side is resting starters, dealing with late injury news, or facing a schedule edge, so the current price should be read as a live consensus rather than a static forecast.

The key trader watches are the final injury report, any late announcement on minutes restrictions, and confirmation that the game starts on schedule at 7:00PM ET. Because the market stays open if the game is postponed and only resolves 50-50 if it is cancelled outright with no make-up, schedule risk matters as much as the on-court matchup. Any pre-tip lineup change, especially involving a star-heavy Liberty rotation, can shift the implied probability quickly before the settlement window closes.

Methodology

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

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
