The market duration extends as long as the Skibidi wars are part of the Skibidi Toilet series by DaFuqBoom. The resolution must be confirmed as canon by the series creator. If there are no updates for 6 months or the series ends in a cliffhanger, it resolves as Unknown. Introduction of a major faction adds them under Other. If neither side wins, both are destroyed, or a stalemate or peace agreement occurs, it resolves as None.
@soweliSon I have now explored the Skibidi universe in more depth. I suspect the "cameraheads" option was meant to stand for The Aliance, which actually consists of three separate factions: Cameramen, Speakermen, and TV Men. It is uncertain whether they will remain allied (especially in light of Skibidi Toilet 76 finale), so you might want to add the other two factions as separate options.
