Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories, which can be made all-loop finite, both in the gauge and Yukawa couplings and in the soft supersymmetry breaking sector. This remarkable property, based on the reduction of couplings at the quantum level, provides a drastic reduction in the number of free parameters, which in turn leads to an accurate prediction of the top quark mass, and predictions for the Higgs boson mass and the supersymmetric spectrum. Here we examine the predictions of three FUTs taking into account a number of theoretical and experimental constraints.
