The liar paradox in question form. Please answer according to the title. If the market will resolve to NO, then the question in the title should be answered positively, with a YES. Vice versa, if the market ends up resolving to YES, then your answer should be NO.

PS: I will toss a weighted coin according to the chance at closing and invert the answer. Equivalently, this market will be resolved to a random boolean with a positive chance of (1-P) where P is the market at closing. (Supplementary riddle: most likely the chance of resolving YES is equal to P.)
