Read the full assessment
The rules clearly define how the top model is determined by specifying the exact website, URL tab, and filter setting on the Chatbot Arena leaderboard at a precise timestamp on December 31, 2026. An explicit tie-breaking sequence is established, progressing from leaderboard rank to granular unrounded arena scores, and finally to alphabetical company name ordering. The primary condition to monitor is website uptime at the designated check time, though the rules provide a direct delay mechanism if the site is temporarily down, resorting to an unspecified fallback source only if the platform becomes permanently unavailable.

Resolution rules
This market will resolve according to the company which owns the model which has the highest arena rank based off the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on December 31, 2026, 12:00 PM ET.
Results from the "Rank" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the style control off will be used to resolve this market.
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 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 “xAI”). This market will resolve based on the company that occupies first place under this ranking system.
The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.
