Kureka:
Unlikely. Polities usually develop borders for one of two reasons:
1: they run in to opposition to further expansion from the neighbors
2: they run to the edge of their ability to travel (nowhere they can reach)
the very rare third case:
3: they can't hold a larger polity together, and so create a closed society to prevent it from growing beyond control (China, Mongolia.)
wide zones between polities are a problem, as sooner or later, someone will unify a couple, and then they become a gap-filler themselves.
So unless there are barriers to travel, social, economic, religious, or astrographic, all space WILL be claimed. Perhaps not controlled, but definitely claimed.
Independent worlds would be the rarity; they'd band together simply out of self-preservation given large neighbors.
