Delay / cancellation / revision fallback

If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie still remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “SpaceXAI”). If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve to "Other".

Cross-venue & fine-print settlement trap

Cross-venue & fine-print settlement trap: Polymarket reads arena.ai leaderboard at a fixed check time with style control off; other venues may use a different view (style control on, a different category) or check time, so the #1 model can differ.
