Unified Resolution Criteria (Consistent across platforms)

All platforms use the same resolution logic for determining game outcomes, tie scenarios, cancellations, and first-inning runs, relying on official MLB statistics or credible reporting if necessary.Primary resolution logic: Official final statistics of the event as recognized by MLB or a consensus of credible reporting

Core resolution logic:

  • If the Boston Red Sox win the game, the market resolves to 'Boston Red Sox'
  • If the Athletics win the game, the market resolves to 'Athletics'
  • If the game is postponed, the market remains open until completed

  • If at least one run is scored in the first inning by either team, the market resolves to 'Yes'; otherwise, it resolves to 'No'

Edge cases & clarifications:

  • Postponement: The market remains open until the game is completed. If the game is canceled entirely with no make-up game, it resolves 50-50
  • Tie: If the game ends in a tie, the market resolves 50-50
  • First Inning Runs: The market resolves to 'Yes' if at least one run is scored in the first inning by either team; otherwise, it resolves to 'No'
