Kalshi's match-result market contains a logical tautology—it resolves Yes for Avispa win, Hiroshima win, OR tie, meaning it will always resolve Yes unless the game is canceled. This is fundamentally incompatible with Polymarket's binary spread markets and makes Kalshi's market unresolvable as a true prediction instrument.
Hero Tip:
Avoid trading Kalshi's match-result market until clarification is provided. Polymarket's spread and over/under markets are logically sound and can be traded with confidence. If you hold Kalshi positions, request explicit confirmation of whether the market is intended as a three-way categorical or if one or more outcomes should resolve No.
Critical Divergence Points:
Polymarket: All markets (spreads, totals, BTTS) resolve based on official jleague.jp final score within 90 minutes plus stoppage time. Spread markets are binary: Avispa -1.5 resolves Yes only if Avispa wins by exactly 2+ goals, otherwise No. Cancellation = 50-50 split. Key quote: 'This market will resolve to Avispa Fukuoka if Avispa Fukuoka win the game by 2 or more goals. Otherwise, this market will resolve to Sanfrecce Hiroshima.'
Kalshi: Match-result market states: 'If Hiroshima wins... then Yes. If Tie wins... then Yes. If Avispa wins... then Yes.' This creates a logical tautology where all possible match outcomes resolve to Yes, making the market non-predictive and unresolvable as a binary instrument. No explicit cancellation or postponement clause provided.
