Market context

The underlying real-world event is the WNBA game between the Portland Fire and the Chicago Sky, played on 26 June 2026 at 7:30pm ET, where the Chicago Sky secured a decisive 124-94 victory[3]. Kamilla Cardoso set a WNBA record by shooting 13 for 13 from the field, scoring a career-high 30 points to lead the Sky[3]. The market’s current 0% YES probability for a Portland Fire win aligns perfectly with this settled outcome, as historical precedents show that prediction markets resolve definitively once the final score including overtime is confirmed[1]. Comparable cases in sports betting illustrate that when a team wins by a large margin—such as the Sky’s 25-point victory—the probability of the opposing team winning collapses to zero immediately after the game concludes[1].

Traders should monitor official WNBA announcements regarding game postponements or cancellations, as these are the only catalysts that could keep the market open or trigger a 50-50 resolution if no make-up game occurs[1]. The settlement window ends on 26 June 2026 at 23:30 UTC, meaning any delay beyond this point would be critical for market status[1]. Recent coverage from ESPN confirms the final score and highlights, removing ambiguity about the result[3]. For accessibility, German GlüStV regulations and US CFTC reach define the legal boundaries for such markets, while the ‘no-KYC up to $1,500’ feature allows users to participate without identity verification, enhancing accessibility for this specific market within regulatory limits. This structure ensures compliance while maintaining broad participation for sports-based prediction markets.

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

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.
