In this paper, we study Betti splittings of cover ideals of bipartite graphs. We prove that if Formula: see text is the cover ideal of a bipartite graph then the Formula: see text-partition of Formula: see text is a Betti splitting for any Formula: see text. We also prove that multigraded Betti numbers of any squarefree monomial ideal can appear in a certain part of multigraded Betti numbers of the cover ideal of a bipartite graph.
