Polymarket settles on three binary outcomes (draw, Bologna win, Aston Villa win) covering all possible 90-minute match results, while Kalshi settles on goal-margin thresholds (wins by more than 1.5 or 2.5 goals) that exclude draws and narrow 1-goal margins, creating fundamentally different settlement scopes.
Hero Tip:
If you bet on Polymarket, your YES/NO outcome maps directly to a single match result (draw, Bologna win, or Aston Villa win). On Kalshi, your YES outcome requires a decisive margin of at least 1.5+ or 2.5+ goals—a draw or 1-goal win resolves NO on all four Kalshi markets. Arbitrage risk exists if you expect a close match or draw.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket offers three mutually exclusive binary markets covering all possible 90-minute outcomes—draw, Bologna win, or Aston Villa win. Each market resolves YES for exactly one outcome and NO for all others. Key quote: 'If the game ends in a draw, this market will resolve to Yes. Otherwise, this market will resolve to No' (draw market); 'If Bologna FC 1909 wins, this market will resolve to Yes. Otherwise, this market will resolve to No' (Bologna win market).
Kalshi: Distinct stance: Kalshi offers four markets all resolving YES only if either team wins by a margin exceeding a threshold (1.5 or 2.5 goals). Draws and narrow wins (1-goal margins) resolve NO on all four markets. Key quote: 'If Bologna wins by more than 2.5 goals... then the market resolves to Yes' and 'If Aston Villa wins by more than 1.5 goals... then the market resolves to Yes'—no market covers draws or sub-threshold margins.
