If PBHs are formed due to an enhanced scalar-perturbation amplitude, their formation is inevitably accompanied by the generation of gravitational waves (GWs). We show that LISA will be able to observe the GWs associated to the formation of PBHs around 10⁻¹² solar masses, which may form the entirety of the dark matter. We also discuss how the computation of the PBHs abundance and the induced GWs are affected by non-gaussian corrections.
