Closing the Mass Window for Stupendously Large Black Holes

We show that primordial black holes (PBHs) in the Stupendously Large Black Hole mass range (M 1011\,M) produce isocurvature perturbations exceeding current Planck Cosmic Microwave Background limits, thereby excluding them as a significant dark matter component.
