Kalshi market structure is logically incoherent: all three possible match outcomes (NYCFC win, draw, Cincinnati win) resolve to YES, making the market unresolvable and contradicting the binary nature of prediction markets. Polymarket uses three separate binary markets with mutually exclusive resolution logic.
Hero Tip:
Avoid the Kalshi market entirely—it is fundamentally broken. On Polymarket, treat the three markets as a complete partition: exactly one will resolve YES and two will resolve NO. Arbitrage is impossible due to Kalshi's logical failure.
Critical Divergence Points:
Polymarket: Three separate binary markets covering all possible outcomes: NYCFC win resolves YES only if NYCFC wins; Draw resolves YES only if match ends in a draw; Cincinnati win resolves YES only if Cincinnati wins. Exactly one market resolves YES. Quote: 'If New York City FC wins, this market will resolve to Yes. Otherwise, this market will resolve to No.'
Kalshi: Single market with three resolution conditions, all mapping to YES: 'If New York City wins...then the market resolves to Yes. If Tie wins...then the market resolves to Yes. If Cincinnati wins...then the market resolves to Yes.' This creates a logical impossibility where every possible match outcome triggers a YES resolution, leaving no NO resolution path.
