Kalshi market structure is fundamentally incompatible with Polymarket markets. Kalshi resolves YES for ANY outcome (Ismaily win, Modern win, or tie), while Polymarket markets are outcome-specific (spread bets, totals, BTTS). These are logically contradictory and unresolvable as a unified group.
Hero Tip:
Do not cross-hedge Kalshi against Polymarket spreads or totals. Kalshi's YES resolution is guaranteed regardless of match result, making it a pure event-occurrence bet, not an outcome bet. Polymarket markets require specific score outcomes. Treat them as separate instruments.
Critical Divergence Points:
Polymarket: All 9 markets are outcome-specific: spread bets (Ismaily -1.5/-2.5, Modern -1.5/-2.5), over/under totals (1.5, 2.5, 3.5, 4.5), and both teams to score. Each resolves YES or NO based on the final score. Quote: 'This market will resolve to [specific outcome] if [specific score condition]. Otherwise, this market will resolve to [opposite outcome].'
Kalshi: Single market resolves YES if the match occurs and completes (any outcome: Ismaily win, Modern win, or tie). No outcome differentiation. Quote: 'If Ismaily wins...then the market resolves to Yes. If Modern wins...then the market resolves to Yes. If Tie wins...then the market resolves to Yes.'
