We study a rotating Bose-Einstein condensate in a homogeneous trap in the framework of the Gross-Pitaevskii theory above the first critical speed, i.e., we consider the regime with many vortices but a density close to the vortex-free prole. We prove that the vortex distribution of the ground state is not uniform and is given by an explicit measure minimizing a suitable renormalized energy.''
