Unified Resolution Criteria (Consistent across platforms)
Polymarket and Kalshi resolve all markets based on the official final score from the Brazil Série A match scheduled for March 18, 2026, after 90 minutes plus stoppage time, with identical spread thresholds, over/under totals, and both-teams-to-score logic.
Primary resolution logic:
Official final score published on cbf.com.br (Confederação Brasileira de Futebol), with fallback to consensus of credible reporting if official statistics are not published within 2 hours after match conclusion.
Core resolution logic:
Spread markets resolve based on goal differential: Santos FC (-2.5) resolves YES if Santos wins by 3+ goals; Santos FC (-1.5) resolves YES if Santos wins by 2+ goals; SC Internacional (-2.5) resolves YES if Internacional wins by 3+ goals; SC Internacional (-1.5) resolves YES if Internacional wins by 2+ goals.
Over/Under markets resolve based on combined goals: O/U 1.5 resolves Over if combined total is 2+; O/U 2.5 resolves Over if combined total is 3+; O/U 3.5 resolves Over if combined total is 4+; O/U 4.5 resolves Over if combined total is 5+.
Both Teams to Score resolves YES if both Santos FC and SC Internacional each score at least one goal; resolves NO if either team scores zero goals.
All markets refer only to outcomes within the first 90 minutes of regular play plus stoppage time, excluding extra time or penalties.
If the game is postponed, markets remain open until completion. If canceled entirely with no make-up game, all markets resolve 50-50.
Edge cases & Clarifications:
Game Postponement: If the match is postponed, all markets remain open and unresolved until the game is completed on its rescheduled date.
Game Cancellation: If the game is canceled entirely with no make-up game scheduled, all markets in the group resolve 50-50.
Incomplete Match: If the game is started but not completed (e.g., abandoned), resolution follows the official final score published by cbf.com.br for the portion played.
Delayed Official Statistics: If cbf.com.br does not publish official final match statistics within 2 hours after match conclusion, resolution uses consensus of credible reporting sources.
Timing:
Resolution occurs upon publication of the official final score by cbf.com.br, or within 2 hours after match conclusion via consensus reporting if official statistics are delayed.
