We don't have a model for dark matter. It is called "dark" because it is unknown. We are currently in the early stages of creating a model to explain observations, one good enough to make predictions. Several models, actually, of which dark matter - that is, "matter that only interacts gravitationally" - is the only candidate that can explain the widest range of observations.
