A submanifold in a real space form attaining equality in the DDVV inequality at every point is called a Wintgen ideal submanifold. They are invariant objects under the Moebius transformations. In this paper, we classify those Wintgen ideal submanifolds of dimension m>3 which are Moebius homogeneous. There are three classes of non-trivial examples, each related with a famous class of homogeneous minimal surfaces in Sn or CPn: the cones over the Veronese surfaces S2 in Sn, the cones over homogeneous flat minimal surfaces in Sn, and the Hopf bundle over the Veronese embeddings of CP1 in CPn.
