Results from the "Arena Score" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the style control on will be used to resolve this market. If two models are tied for the best arena score at this market's check time, resolution will be based on whichever company's name, as it is described in this market group, comes first in alphabetical order (e.g. if both were tied, "Google" would resolve to "Yes", and "xAI" would resolve to "No") The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/.
