Resolution criteria: This market resolves to the company whose model is ranked #1 on the overall Chatbot Arena leaderboard at 00:00 UTC on January 1, 2027. If no snapshot exists at that exact time, I will use the first leaderboard update on or after January 1, 2027. If Chatbot Arena is discontinued before then, this market will resolve based on its officially designated successor, or be canceled if no successor exists.
