In a two-component dark matter model, a first-order phase transition can produce Fermi-balls and gravitational waves, with Fermi-balls potentially contributing up to about 30% of the dark matter relic density.

abstract
We discuss inflation and dark matter in the inert doublet model coupled non-minimally to gravity where the inert doublet is the inflaton and the neutral scalar part of the doublet is the dark matter candidate. We calculate the various inflationary parameters like $n_s$, $r$ and $P_s$ and then proceed to the reheating phase where the inflaton decays into the Higgs and other gauge bosons which are non-relativistic owing to high effective masses. These bosons further decay or annihilate to give relativistic fermions which are finally responsible for reheating the universe. At the end of the reheating phase, the inert doublet which was the inflaton enters into thermal equilibrium with the rest of the plasma and its neutral component later freezes out as cold dark matter with a mass of about 2 TeV.

Fermi-ball in a multicomponent dark matter framework and its gravitational wave signatures
In a two-component dark matter model, a first-order phase transition can produce Fermi-balls and gravitational waves, with Fermi-balls potentially contributing up to about 30% of the dark matter relic density.
