Primordial Black Holes (PBHs) might comprise a significant fraction of the dark matter in the Universe and can give rise to observable signatures in current and future gravitational wave (GW) experiments. Focusing on the formation of PBHs in the mass range probed by the LIGO/Virgo/KAGRA detectors, I will first discuss the main features of a population of PBH mergers, highlighting their smoking-gun signatures that can be searched for with GW detectors. I will then present the results of a Bayesian multi-population inference of the GWTC-3 dataset including a subpopulation of PBH mergers, derived modelling directly the curvature power spectrum parameters. Finally, I will conclude by forecasting prospects to constrain this scenario with future GW experiments.
