We investigate the consistency of a scenario in which the baryon asymmetry, dark matter, and the cosmic density perturbation are generated simultaneously through the evaporation of primordial black holes (PBHs). This scenario can explain the coincidence of the dark matter and baryon densities of the Universe, and is free from the isocurvature perturbation problem. We show that this scenario predicts the masses of PBHs, right-handed neutrinos and dark matter, the Hubble scale during inflation and the non-Gaussianity. We also discuss the testability of the scenario by detecting high-frequency gravitational waves from PBHs.
