Kalshi presents three separate binary markets (Japan wins, Scotland wins, Tie) that each resolve YES independently, while Polymarket structures three mutually exclusive markets (Scotland wins, Draw, Japan wins) where exactly one resolves YES. This creates fundamentally different settlement logic: Kalshi allows multiple YES resolutions simultaneously, whereas Polymarket enforces a single outcome.
Hero Tip:
If you trade on Kalshi, understand that all three markets can resolve YES at once (e.g., if Scotland wins, both the Scotland market AND the Tie market would resolve YES if a tie occurs — but only one outcome is possible per match). On Polymarket, exactly one of the three markets will resolve YES, making them true mutually exclusive bets. Do not assume Kalshi and Polymarket payouts will align; verify the actual match result against each platform's specific resolution rules.
Critical Divergence Points:
Kalshi:
Outlier: Kalshi presents three independent binary markets, each resolving YES if its specified outcome occurs (Japan wins, Scotland wins, or Tie). The rules state 'If Japan wins... then the market resolves to Yes' and separately 'If Scotland wins... then the market resolves to Yes' and 'If Tie wins... then the market resolves to Yes,' implying all three can resolve YES simultaneously depending on the match result, though logically only one outcome will occur.
Polymarket:
Aligned with Kalshi on scope and timing: Polymarket also covers the same match (Scotland vs. Japan on 2026-03-28) within 90 minutes plus stoppage time, using FIFA as the primary resolution source. However, Polymarket structures three mutually exclusive markets (Scotland win, Draw, Japan win) where exactly one resolves YES and the others resolve NO, enforcing a single outcome per match. Polymarket also includes explicit cancellation logic: 'If the game is canceled entirely, with no make-up game, this market will resolve No' for win markets but 'resolve Yes' for the draw market.
