This event group covers the outcome of a professional Brasileiro Serie A soccer match between Mirassol FC and Santos FC scheduled for March 10, 2026. Markets are offered on three mutually exclusive outcomes: Mirassol win, Santos win, or draw, all measured at 90 minutes plus stoppage time (regular play only).
Polymarket and Kalshi use incompatible market structures and diverge on cancellation resolution. Polymarket's Draw market resolves Yes on cancellation while Win markets resolve No; Kalshi provides no explicit cancellation guidance and uses independent binary outcomes rather than mutually exclusive logic.
Hero Tip:
Do not assume these markets are equivalent. Polymarket's three markets are designed as mutually exclusive outcomes with explicit cancellation rules. Kalshi's three markets appear to be independent binary propositions with no stated cancellation protocol. Before the match, verify Kalshi's cancellation policy directly with the platform. If you hold positions on both platforms, monitor for divergence in cancellation scenarios.
Critical Divergence Points:
Polymarket: Offers three mutually exclusive binary markets (Mirassol Win, Draw, Santos Win). Cancellation with no makeup game: Mirassol Win resolves No, Draw resolves Yes, Santos Win resolves No. Quote: 'If the game is canceled entirely, with no make-up game, this market will resolve No' (Mirassol/Santos) and 'Yes' (Draw).
Kalshi: Offers three independent binary markets (Mirassol Wins, Santos Wins, Tie Wins), each resolving Yes if that outcome occurs. No explicit cancellation clause provided. Quote: 'If [outcome] wins the Mirassol vs Santos professional Brasileiro Serie A soccer game originally scheduled for Mar 10, 2026 after 90 minutes plus stoppage time, then the market resolves to Yes.' Ambiguous on what happens if game is canceled.
