Burnley FC vs. Brighton & Hove Albion FC

Critical divergence points:

• Polymarket: Aligned with standard sports betting logic: Polymarket offers three mutually exclusive binary markets where exactly one outcome (Burnley win, Brighton win, or Draw) will occur and resolve YES, while the other two resolve NO. The resolution source is 'official statistics of the event as recognized by the governing body or event organizers' with a 2-hour fallback to credible reporting. All three markets reference '90 minutes of regular play plus stoppage time' and handle postponement identically (remain open until completion) and cancellation identically (resolve NO, except Draw resolves YES if canceled).
• Kalshi: Outlier: Kalshi presents three separate markets framed as independent YES/NO propositions: 'If Brighton wins... then resolves to Yes', 'If Burnley wins... then resolves to Yes', and 'If Tie wins... then resolves to Yes'. This structure is logically incoherent because exactly one outcome will occur, yet all three markets are written to resolve YES for their respective outcomes, meaning traders cannot determine whether they are betting on a single outcome or a portfolio. No resolution source, postponement rules, or cancellation clause is specified. This violates fundamental market design principles and makes the market unresolvable.
