Market context

The Dallas Wings and Chicago Sky played on 20 May, and Polymarket is already pricing this contract at 100% for Dallas Wings, with USDC settled through Polygon conditional tokens once the result is final. For traders, that kind of pricing usually means the market is effectively treating the game as decided, but the contract still depends on the official WNBA result and the settlement window. If the game had been postponed, the position would have stayed open until completion; if it had been cancelled outright, the market would have resolved 50-50.

Recent comparable spots in WNBA moneyline markets tend to move to certainty only once the final score is reflected in the official data feed, not merely on live boxscore snapshots. ESPN listed Dallas as a 99-89 winner over Chicago, which matches the sort of end-state that would lock the market, while Fox Sports’ boxscore also shows Dallas winning in Chicago. In practice, the main historical lesson is that Polymarket prices near 100% are usually about confirmation risk, not outcome risk: the on-chain payout follows the verified game result, and any dispute is about whether the event has truly resolved under the market rules.

What still matters for a trader is the close-out chain: official WNBA scorekeeping, any post-game corrections, and whether the contest was completed within the settlement window ending 2026-05-21T01:00:00Z. The relevant catalyst is therefore not a fresh preview, but the publication and permanence of the official final score. ESPN’s live game page already shows the final and Fox Sports’ boxscore aligns with Dallas winning, so the remaining watchpoint is administrative rather than sporting.

Methodology

We track Dallas Wings vs. Chicago Sky 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

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.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
