This market resolves YES if Donald Trump or his lawyers have filed for any form of bankruptcy as listed here: https://www.uscourts.gov/services-forms/bankruptcy/bankruptcy-basics as of the day after election day and there is no significant contention regarding that being true, or there is some shady rich person money strategy employed that is widely agreed to be equivalent to declaring bankruptcy (ie. Bailout, etc.) in the comments.
This market resolves NO if there is no contention over whether Donald Trump or his lawyers have done something equivalent to bankruptcy in the negatory direction.
This market resolves N/A if the contention over whether he has done so is too high for there to be a satisfactory justification for either above option.
