Dynamical instability is shown to occur in differentially rotating polytropes with N = 3.33 and T/|W| >= 0.14. This instability has a strong m=1 global mode, although the m=2, 3, and 4 modes also appear. Such instability may allow a centrifugally-hung core to begin collapsing to neutron star densities on a dynamical timescale. If it occurs in a supermassive star, it may produce gravitational radiation detectable by LISA.
