PortlandFire vs. Washington Mystics

Platform comparison

Market context

The Portland Fire and Washington Mystics played out a quadruple-overtime thriller on June 28, 2026, where the Mystics edged the Fire 124–123 in a game that stretched well past its scheduled end time [1]. This result means the prediction market titled "PortlandFire vs. Washington Mystics" has already settled, with the outcome resolving to "Washington Mystics" rather than the Portland Fire. The current crowd-implied probability of 0% YES for PortlandFire is therefore accurate, as the game has concluded and the Fire did not win.

Historically, WNBA markets with 0% probability for one side after a game has finished are straightforward, as conditional tokens on Polygon (USDC) lock in the winner once the final score is confirmed [1]. Comparable cases from past seasons show that when a game ends in overtime, the market resolves based on the final score including all overtime periods, with no ambiguity about the winner [3]. In this instance, the Mystics' victory in 4OT is definitive, and the on-chain mechanics ensure the market closes immediately without further trading.

Traders should watch for official WNBA announcements confirming the final score and any post-game reports, though the ESPN broadcast already confirms the 124–123 result [1]. No further catalysts are needed, as the game has been completed and the settlement window (ending 2026-06-28T19:00:00Z) has passed [2]. The only dependency is the official league confirmation, which is already reflected in the live score tracker and broadcast highlights [3]. With the result settled, the market remains closed, and no further action is required.
