This event group covers the Bundesliga match between 1. FSV Mainz 05 and Eintracht Frankfurt scheduled for March 22, 2026. The markets capture all three possible outcomes: Mainz win, Frankfurt win, or draw. Resolution is based on the result after 90 minutes of regular play plus stoppage time, excluding extra time and penalties.
Polymarket offers three mutually exclusive binary markets (Frankfurt win, Mainz win, draw), each resolving independently to YES or NO, while Kalshi presents three separate markets that each resolve to YES if their respective outcome occurs, creating a logical contradiction: on Polymarket, exactly one market resolves YES; on Kalshi, exactly one market also resolves YES, but Kalshi's market structure allows all three to theoretically resolve YES simultaneously if the platform treats them as independent affirmations rather than mutually exclusive outcomes.
Hero Tip:
Critical: Do not assume Polymarket and Kalshi will settle identically. On Polymarket, betting all three outcomes guarantees exactly one YES and two NOs. On Kalshi, the market structure is ambiguous—clarify with Kalshi whether their three markets are mutually exclusive (only one resolves YES) or independent (each resolves YES/NO based on its own condition). If independent, you could theoretically win all three Kalshi markets simultaneously, which is impossible on Polymarket. Verify Kalshi's settlement rules before trading across both platforms.
Critical Divergence Points:
Polymarket:
Distinct stance: Polymarket structures the event as three mutually exclusive binary markets where exactly one outcome (Frankfurt win, Mainz win, or draw) will resolve YES and the other two will resolve NO. Each market explicitly states 'Otherwise, this market will resolve to No,' enforcing mutual exclusivity. Resolution source is official Bundesliga statistics or credible consensus within 2 hours of match conclusion, and the market scope is 90 minutes plus stoppage time only.
Kalshi:
Distinct stance: Kalshi presents three separate markets, each with an independent YES/NO resolution condition: 'If Mainz wins... then resolves to Yes,' 'If Frankfurt wins... then resolves to Yes,' and 'If Tie wins... then resolves to Yes.' The market structure does not explicitly state mutual exclusivity or clarify whether all three markets can resolve YES simultaneously or whether only one will. Resolution source and timing are not specified in the provided rules, and the scope is stated as '90 minutes plus stoppage time (does not include extra time or penalties).'
