Quote: A Guild Challenge is a continuous event that occurs automatically for a period of 48 hours. During this time, a maximum of 8 guilds of similar ranking.

I guess you either don't have enough guilds to make the challenge appear, or that such an event already started some time ago. I am not playing the game anymore, so i cannot tell you more details.
