Non-relativistic Dark Matter (DM) can be accelerated by scattering onhigh-energy cosmic-ray (CR) electrons. This process leads to a sub-populationof relativistic or semi-relativistic DM which extends the experimental reachfor direct detection in the sub-GeV mass regime. In this paper we examine thecurrent and future potential of this mechanism for constraining models of lightdark matter. In particular, we find that Super-Kamiokande and XENON1T data canalready provide leading constraints on the flux of dark matter that has beenaccelerated to high energies from cosmic ray electrons. We also examine futureprojected sensitivities for DUNE and Hyper-K, and contrary to previousfindings, conclude that DUNE will be able supersede Super-K bounds oncosmic-ray upscattered DM for a variety of DM models.
