I believe the author has said that the story is not so much about Ainz fighting an equal foe, but is more of showing a normal japanese salary man filling the shoes of the evil overlord.

So far 9 volumes have been released and that makes about 50% of the story complete. So it's still a way to go to see if there is gonna be any rivals appearing but for the anime atleast in season 1 there will be no rival or anyone even close to him in strenght except for his own NPC, it will probably not be untill anime season 3-4 at earliest when and if it at that point goes beyond vol 9, unless there are some kind of filler episode or something.
