Polymarket and Kalshi use fundamentally incompatible resolution logic for the draw market. Polymarket's draw market resolves YES if the game is canceled with no make-up, while Kalshi's draw market resolves YES only if the match actually ends in a tie after 90 minutes plus stoppage time. This creates a logical contradiction: the same cancellation event cannot simultaneously resolve YES on one platform and NO on another.
Hero Tip:
If you trade the draw market, your profit/loss outcome depends entirely on which platform you use. If the game is canceled, Polymarket draw bets WIN while Kalshi draw bets LOSE. If the game is played and ends 0-0, both platforms WIN. Avoid cross-platform arbitrage on the draw unless you are certain the game will be played to completion.
Critical Divergence Points:
Polymarket:
Outlier: Polymarket's draw market resolves YES if the game is canceled entirely with no make-up game, regardless of whether a tie actually occurs. The rules state: 'If the game is canceled entirely, with no make-up game, this market will resolve to Yes.' This creates a scenario where a draw market can resolve YES without any match being played.
Kalshi:
Distinct stance: Kalshi's draw market resolves YES only if the match is actually played and ends in a tie after 90 minutes plus stoppage time. The rules state: 'If Tie wins the Pisa vs Torino professional Serie A soccer game originally scheduled for Apr 5, 2026 after 90 minutes plus stoppage time, then the market resolves to Yes.' Cancellation is not addressed, implying standard sports market convention (canceled game = no resolution or NO).
