Market context

The Portland Fire face the Chicago Sky in a WNBA matchup scheduled for 8:00 PM ET on 24 June at Wintrust Arena in Chicago, with the game already concluding in Portland’s favour by a final score of 110–106. On Polymarket, this contract trades at 0% for a Portland Fire win today, reflecting the on-chain reality that the event has settled: conditional tokens on the Polygon network have resolved, USDC payouts are locked, and the market will resolve to “Chicago Sky” based on the final score including overtime.

Historically, similar WNBA markets where the outcome was decided before the settlement window closed have consistently resolved at 0% for the losing side, as seen in the May 9, 2026 game where Chicago defeated Portland 98–83, with Kamilla Cardoso scoring 22 points and 14 rebounds [3]. In such cases, the on-chain mechanics ensure immediate resolution once the official result is confirmed, leaving no room for speculative re-pricing after the game ends.

Traders should monitor official WNBA announcements regarding any potential postponements or cancellations, though none are expected given the game’s completion. The primary dependency is the league’s final score confirmation, which has already been published by ESPN, confirming Portland’s 110–106 victory [1]. No further catalysts are relevant, as the result is final and the market will resolve accordingly.

Methodology

We track PortlandFire 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.
