It may miss subsequent developments.** ## The question, as the venue words it Will Google have the best AI model at the end of December 2026? ## How this market settles 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. ## Evidence you can inspect _These labels describe how a claim relates to the question.

No individual review. It rests on 30 claims from 11 publishers; anything not reported in those sources is not represented here. The report recorded 6 resolution risks, listed with this brief. - 'Google-owned model' is not explicitly defined — could include DeepMind or other Alphabet subsidiaries; unclear if subsidiary models count as Google - The leaderboard may update continuously; exact snapshot at 12:00 PM ET may differ from what is visible moments before or after - 'Permanently unavailable' for the resolution source is not defined, leaving the fallback resolution source unspecified - Timezone gap: market end date is 17:00 UTC (12:00 PM ET in winter/EST), but ET in December is UTC-5, so 17:00 UTC = 12:00 PM EST — this appears consistent but should be confirmed - Granular unrounded Arena scores referenced in tiebreaker may not be publicly accessible or easily verifiable - No explicit definition of which models count as 'Google' vs other companies if Google acquires or partners with another AI lab by 2026 ## Publication history - Published 4 November 2026; research dated 4 November 2026. ## Since the previous brief This is the first published brief for this event.
