People are also trading
@AlpAtalan You can't change the question to have a different meaning after trading has occurred. I'm reverting the title to its original state (it's up to you where you leave the close date). It should resolve based on the subscriber count "Before 22 may 2025" (you can choose how to define that, e.g. timezone & etc)
Title -> Will MrBeast reach 400 million subscribers before 22 May 2025?

@Ziddletwix (in reality creators have some leeway here—like if the description is informal & they need to update things and shift it around to define the question after trading has occurred, that's often acceptable. but changing to a different resolution date without explanation a while after trading has occurred is obviously not allowed so this is an easy case).
@ChristopherRandles Uh oh, that's not good.
@AlpAtalan It's not a good idea to change the resolution criteria like that.
@Ziddletwix On 17 May the creator changed the title to a different meaning. The question was originally about the subscriber count on 22 May 2025.
@ZandaZhu close date is up to the creator
And close date is irrelevant to resolution date. This could have a close date of august listed and that wouldn’t change when it resolves by
