Unified Resolution Criteria (Consistent across platforms)
All markets across Polymarket and Kalshi use identical resolution logic based on the official final score from mlssoccer.com after 90 minutes plus stoppage time, with consistent handling of postponements (market remains open) and cancellations (50-50 resolution).
Primary resolution logic:
Official final score published on mlssoccer.com
Core resolution logic:
All markets resolve based on the official final score from mlssoccer.com within 90 minutes of regular play plus stoppage time only.
Spread markets (±1.5, ±2.5) resolve YES for the named team if they win by the specified margin or greater, otherwise NO.
Both Teams to Score resolves YES if both teams score at least one goal, NO if either team scores zero.
If the game is postponed, markets remain open until completion. If canceled with no make-up game, all markets resolve 50-50.
Edge cases & Clarifications:
Postponement: If the game is postponed, the market remains open and does not resolve until the game is completed and the official final score is published.
Cancellation without Make-up: 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, resolution is based on the official final score published by mlssoccer.com for the portion played.
Delayed Official Statistics: If mlssoccer.com does not publish final match statistics within 2 hours after the event's conclusion, a consensus of credible reporting may be used as the resolution source.
Timing:
Resolution occurs upon publication of the official final score on mlssoccer.com after the completion of 90 minutes plus stoppage time, or within 2 hours thereafter if official statistics are delayed.
