Divergence Detected
Issue:
Kalshi moneyline markets contain a logical contradiction where both possible fight outcomes (Osbourne win and Idiris win) are specified to resolve to Yes, making the market fundamentally unresolvable. Polymarket provides coherent binary resolution logic.Hero Tip:
Do not trade Kalshi moneyline markets for this fight. Use Polymarket winner market exclusively. All derivative markets (method, distance) across both platforms share consistent edge-case handling: draws, no-contests, and postponements beyond March 7, 2026 resolve 50-50.Critical Divergence Points:
- Kalshi: Moneyline markets state both 'If Alibi Idiris wins...resolves to Yes' AND 'If Ode Osbourne wins...resolves to Yes'. This creates a logical impossibility where every outcome resolves Yes, making the market unresolvable.
- Polymarket: Winner market resolves to 'Osbourne' if Ode' Osbourne is officially declared winner, 'Idiris' if Alibi Idiris is officially declared winner, and '50-50' for draw, technical draw, no-contest, or postponement beyond March 7, 2026. Clear binary logic with defined fallback.
