The close date is arbitrary; either I or a moderator will extend the close date as needed until a woman becomes president of the United States.

For purposes of this market, "woman" is someone who identifies as a woman at the time of the respective event. If a politician became President of the United States as a man and then identified as transgender after leaving the Presidency, then that would not satisfy the requirement (unless they were to regain the presidency).

I will not bet in this market.
