This market resolves based on the official outcome of the 2026 MLB World Series using official MLB information, with credible reporting as a secondary source. The rules explicitly permit early resolution to No as soon as the team is mathematically or competitively eliminated from contention. Additionally, if the season is cancelled, delayed beyond December 31, 2026, or concludes without an official champion, the market will resolve to Other rather than Yes or No.
