 Abstract: A significant fraction of cosmological dark matter can be formed by very dense macroscopic objects, for example primordial black holes. Gravitational waves offer a promising way to probe of these kinds of dark matter candidates, in a parameter space region that is relatively untested by electromagnetic observations. In this work we consider an ensemble of macroscopic dark matter with masses in the range $10^{-13}$ - $10^{3}\,M_{\odot}$ orbiting a super-massive black hole. While the strain produced by an individual dark matter particle will be very small, gravitational waves emitted by a large number of such objects will add incoherently and produce a stochastic gravitational-wave background. We show that LISA can be a formidable machine for detecting the stochastic background of such objects orbiting the black hole in the center of the Milky Way, Sgr$\mspace{2mu}$A$^{\!*}$, if a dark matter spike of the type originally predicted by Gondolo and Silk forms near the central black hole.
