It's not ruled out by evidence, AFAIK, and could explain some observational puzzles. https://indico.fnal.gov/event/6199/contributions/94686/attac... (that was 2013; perhaps observations since have made it less likely) 2021 paper: https://arxiv.org/abs/2105.08719 2020 paper: https://www.researchgate.net/publication/342573954_Antimatte... ("a large region of the parameter space remains unconstrained, most notably for nuclear-dense objects.")

Here's a recent (2021) paper on the idea: https://arxiv.org/abs/2105.08719 It has the nice feature of explaining why the density of baryons and the density of dark matter are not too different. Naively, there's no reason to expect the two to be anywhere close to each other. It also offers an explanation for the observed matter-antimatter asymmetry in the universe. Don't believe any theory until it's been well tested.
