    We propose a novel scenario to obtain the correct relic abundance for thermally underproduced dark matter. This scenario utilizes a strongly first-order phase transition at temperature T PT that gives rise to dark matter mass m . Freeze-out in the broken phase can yield the desired abundance in the entire region currently allowed by observational bounds and theoretical constraints for 10 2 T PT ≲ m ≲ 10 4 T PT . We show that the accompanying gravitational waves are strong enough to be detected by many upcoming and proposed experiments. This, in tandem with dark matter indirect searches, provides a multimessenger probe of such models. Positive signals in the future can help reconstruct the potential governing the phase transition and shed light on an underlying particle physics realization.
