Running a wiki farm takes a lot of money. Did you notice how you don't have to pay for your account and how you don't have to pay to create a wiki? How then, does Wikia get the money to pay for maintenance costs? Well, they could ask for donations like Wikipedia does; but they don't. Instead, they use ads. How do you get large ad revenue? By having a lot of views. How do you get a lot of views? By having a large community. Will a private wiki grow to be a large community? Probably not. Therefore, no private wikis.

If you want to have a private wiki, you can use either Miraheze or ShoutWiki (both use MediaWiki just like Wikia). Miraheze is a non-profit so I don't know how much support they give wiki creators. ShoutWiki does provide official support but charges based on a tier system. The base level is free but comes with the least support and fewest features.
