This event group covers a professional Euroleague basketball game between Olympiacos B.C. (Piraeus) and Real Madrid scheduled for April 7, 2026 at 2:15 PM EDT. Markets resolve based on which team wins the match, with contingencies for postponement or cancellation.
Kalshi's resolution logic is fundamentally broken: it resolves to Yes for both possible outcomes (BC Olympiakos wins OR Real Madrid wins), making the market logically unresolvable. Polymarket correctly structures a binary outcome where exactly one team's victory triggers resolution.
Hero Tip:
Do not trade on Kalshi's version of this market. The resolution rules state the market resolves Yes if either team wins, which violates basic binary market logic and creates a data integrity failure. Polymarket's market is the only tradeable version in this group.
Critical Divergence Points:
Polymarket:
Outlier (functional): Polymarket uses proper binary logic where the market resolves to the name of the winning team (Olympiacos B.C. or Real Madrid), with clear handling of postponement (market remains open) and cancellation (50-50 split). Key quote: 'If the Olympiacos B.C. win, the market will resolve to Olympiacos B.C. If the Real Madrid win, the market will resolve to Real Madrid.'
Kalshi:
Outlier (broken): Kalshi's rules state the market resolves Yes if BC Olympiakos wins AND also resolves Yes if Real Madrid wins, creating a logical contradiction where both mutually exclusive outcomes trigger the same resolution. Key quote: 'If BC Olympiakos Piraeus wins...then the market resolves to Yes. If Real Madrid wins...then the market resolves to Yes.'
