The market will resolve to YES if a Google model is the top chatbot on the specified date and for the entire month prior.
The market will resolve to NO if a model from any organization other than Google is the top model during the month before the specified date (and will also resolve NO for subsequent dates).
Exemple:
If LLaMA becomes the top model on January 5th, 2024, the market will resolve as follows:
The market will resolve to NO for all dates after January 5th, 2024, since a model from an organization other than OpenAI has taken the top position.
Even if an OpenAI model regains the top spot later, the market will not change back to YES for any subsequent dates, as the condition for NO was met on January 5th, 2024.
Let's try to reconstruct the chronology from the LMArena Twitter where they publish any notable changes in rankings.

You could also do this (the error-proof way) based on the Git commits, but it's effort.
@LCBOB Please resolve Jan 1st and Feb 1st to YES.
