#1 More smaller promotions split up the pie

While New Japan and All Elite Wrestling may take advantage of a WWE void to grow their businesses, promotions like Ring of Honor, Impact Wrestling, Lucha Underground, Evolve, Pro Wrestling Guerilla, Chikara, House of Hardcore, and Combat Zone Wrestling would all be positioned to vie for a spot as the top wrestling promotion among US fan.
And that’s not to mention other upper tier international companies that might make moves.
In the end, though, one of the most interesting parts about imagining a world without WWE is considering how the pie might be redistributed.
For at least the years to immediately follow such a huge development, we would probably see something akin to the old territory days with a lot of smaller promotions based in their own regions doing the best they can, and walking the line between competition and collaboration before new, clearer front runners emerge.
