I personally think that the only force with a chance of defeating the tyranids is the necrons as due to the fact that the tyranids have been shown to choose to avoid any necron tomb planets that should have been in their path. Due to this the necron tomb ships if they choose to do so, can hunt down hive ships individually and destroy them slowly. This would take a very long time but necrons are effectively immortal and have all the time that they need. Also, it also matters not to the necrons that the other planets have been stripped of everything as their tomb worlds and any worlds that they have claimed or are yet to be devoured by the tyranids will still have lots of resources for them to take unopposed. The imperium cannot stand up against the Tyranids due to the fact that their is almost an infinite number of tyranids and that they are already rotting from the inside. Tau cannot face them as although they may be the only race to match the tyranids in eveloutianary pace, their is not that many tau held worlds Anywa at the moment so they are a very small empire not nearly big enough to contend with the endless swarms of tyranids. Chaos cannot corrupt or make the tyranids go insane and the gods and their daemons power is nulled by the shadow of the warp meaning that in enough bulk, the tyranids could simply smother the eye of terror and the maelstrom starving the gods of anything to feed on and then weakening them so much that they nor their daemons could find a foothold in the mortal realm. Orks would be destroyed by the Tyranids due to the fact that they give absolutely no thought to the tactics and mindlessly charge their enemy giving the tyranids a constant stream of food whilst fighting them. Finally, the Eldar couldn't defeat the tyranids as A) their is simply not enough of them and B) They are already a dying species and finally C) Everything about them is digestible to the tyranids to their ships/planets to their shrines and spirit stones. Also as shown in the valedor book the tyranids can penetrate the web way in the same way all eldar can so they can get to the dark eldar to and devour them.
