Sevilla FC and Valencia CF will compete in a La Liga match scheduled for March 21, 2026. This event group captures three mutually exclusive outcomes: a Sevilla victory, a Valencia victory, or a draw. All markets resolve based on the result after 90 minutes of regular play plus stoppage time, excluding extra time or penalties.
Polymarket defines three mutually exclusive binary markets (Valencia win, Sevilla win, draw) where exactly one resolves YES, while Kalshi defines three independent YES/NO markets that all resolve YES simultaneously if their respective outcomes occur. This creates a logical contradiction: under Kalshi's structure, all three markets would resolve YES for any match outcome, making them non-informative and fundamentally unresolvable as stated.
Hero Tip:
Do not trade across both platforms assuming equivalent exposure. Polymarket offers true mutually-exclusive betting on three outcomes; Kalshi's three markets are logically broken because they all resolve YES for the same event. Clarify with Kalshi whether their markets should be mutually exclusive (like Polymarket) or if the resolution rules contain an error.
Critical Divergence Points:
Polymarket: Outlier: Polymarket structures three separate binary markets (Valencia win YES/NO, Sevilla win YES/NO, draw YES/NO) where exactly one outcome occurs and exactly one market resolves YES. Key quote: 'If Valencia CF wins, this market will resolve to Yes. Otherwise, this market will resolve to No' — applied independently to each of the three markets, creating mutually exclusive resolution.
Kalshi: Outlier: Kalshi defines three independent markets with identical resolution logic: 'If [Valencia/Sevilla/Tie] wins...then the market resolves to Yes.' This means all three markets resolve YES simultaneously for any match outcome (e.g., if Valencia wins, both the Valencia market and the Tie market would resolve YES per the stated rules), creating a logical contradiction and making the markets unresolvable as written.
