While very little is known about dark matter (DM), its cosmological abundance is remarkably well-determined and curiously close to the abundance of ordinary matter. In the first part of the talk, I'll discuss the features of a class of "asymmetric dark matter (ADM)" models that attempt to account for this fact by positing the existence of a "dark asymmetry" analogous to the baryon asymmetry of ordinary matter. These models require large annihilation cross sections and present-day indirect detection constraints are already placing meaningful limits on the parameter space. In addition, I will discuss collider and direct detection prospects for probing these models.
