Resolution rules
This market will resolve according to the company which owns the model which has the highest arena rank based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on October 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market. Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score. Models will be ordered primarily by their leaderboard rank at the market’s check time. 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”). This market will resolve based on the company that occupies first place under this ranking. The resolution source for this market is the arena.ai Text Arena (Overall). 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".

Market explained
This market measures whether Amazon owns the top-ranked AI model on the arena.ai Text Arena (Overall) leaderboard at the end of October 2026. Resolution relies on specific leaderboard settings, excludes AutoEval models, and applies tiebreakers.
How it resolves
The market resolves to Amazon (or Yes) if Amazon owns the top-ranked model on the arena.ai Text Arena (Overall) leaderboard when checked on October 31, 2026, at 12:00 PM ET. The market resolves to another company (or No) if another company owns the top-ranked model under these criteria. Models marked "AutoEval" are excluded from consideration. Ties are broken first by unrounded Arena score, then by alphabetical order of company names. The market resolves to "Other" if the resolution source is permanently unavailable. Resolution is determined by checking the specified leaderboard on arena.ai. If the source is temporarily unavailable at the check time, resolution waits until it comes back online.
