This market will resolve based on the official LMSYS chatbot arena leaderboard (Overall Category).

• Resolution Value: The market resolves to the Model Family that holds the #1 rank on the leaderboard as of December 31, 2026, 11:59 PM PT.

• If the leaderboard has a specific "last updated" timestamp, the update closest to (but not after) the deadline will be used.

• Definition of "Model Family":

  • OpenAI: Includes all GPT-4, GPT-5, or subsequent models.

  • Anthropic: Includes all Claude 3, 3.5, 4, or subsequent models.

  • Google: Includes all Gemini or subsequent models.

  • Other families (e.g., Meta, Mistral) will be resolved as their respective entities.

• Missing Data/Source Failure: If LMSYS is unavailable or hasn't updated for over 90 days prior to the deadline, this market may resolve based on a consensus of secondary benchmarks (e.g., LiveBench) to ensure a fair outcome.

• Update 2025-12-28 (PST) (AI summary of creator comment): Tie Handling: If multiple model families are tied for #1 rank on December 31, 2026, all tied families will resolve YES.
