This event group covers the professional EFL Championship soccer match between Ipswich Town FC and Millwall FC scheduled for March 21, 2026. Markets across Polymarket and Kalshi track the outcome after 90 minutes of regular play plus stoppage time, including win conditions for each team and draw outcomes.
Market structure incompatibility between platforms. Polymarket uses three separate binary markets with distinct cancellation logic for draw outcomes, while Kalshi uses a single three-outcome market with no explicit cancellation clause.
Hero Tip:
Traders holding positions across both platforms face basis risk. Polymarket's draw market resolves Yes on cancellation (no makeup game), but Kalshi's cancellation behavior is unspecified. Verify cancellation protocols with each platform and consider the draw outcome as a potential divergence point if the match is postponed indefinitely.
Critical Divergence Points:
Polymarket:
Three independent binary markets. Millwall Win market: resolves Yes if Millwall wins, No otherwise. Ipswich Win market: resolves Yes if Ipswich wins, No otherwise. Draw market: resolves Yes if draw, No otherwise. Cancellation with no makeup: Win markets resolve No, but Draw market resolves Yes. Resolution source: Official EFL statistics within 2 hours post-match, or credible reporting consensus if delayed.
Kalshi:
Single three-outcome market covering Ipswich Win, Millwall Win, and Tie. Each outcome resolves to Yes if it occurs. No explicit cancellation clause provided. Resolution source: Official EFL Championship records after 90 minutes plus stoppage time (no extra time or penalties).
