Resolution relies on a specific, publicly verifiable third-party leaderboard (Chatbot Arena) with clear numerical rankings and defined tiebreaker procedures, making the outcome largely objective and binary. The primary risk is dependency on a single external data source—if the leaderboard becomes permanently unavailable, the contract would need to select an alternative source, introducing potential disputes over which substitute is most appropriate.
