The market resolves on Jun 6, 2026, after the first inning of the Chicago WS vs Philadelphia game concludes.

Pre-game announcements of starting lineups, bullpen availability, or weather changes (wind direction, temperature) can alter expectations for early scoring. Injury updates to key hitters or pitchers will influence trader positioning. Once play begins, the first few pitches, early at-bats, and defensive positioning provide real-time signals that may prompt rapid repricing. Aggressive early swings, walks, or errors can all trigger market movement as traders reassess the likelihood of a first-inning run before the inning concludes.
