Primordial inflation and Dark Matter (DM) could both belong to the hidden sector. It is therefore plausible that the inflaton, which drives inflation, could couple to the DM either directly or indirectly, thus providing a common origin for both luminous and non-luminous matter. We explore this novel possibility and show that in certain scenarios the DM mass can be correlated with the tensor-to-scalar ratio. This unique correlation can provide us with a new window of opportunity for unraveling the properties of DM.
