The Imaging X-ray Polarimetry Experiment (IXPE) has provided data for a wide range of fields, including the study of accretion around the supermassive black holes in the nuclei of active galaxies and compact objects in Galactic X-ray binaries.  I will provide an overview of how IXPE works and its fundamental characteristics relevant to the study of AGN and X-ray binaries.  I will summarize the results from IXPE observations of radio quiet AGN, separating the sources into two groups: those with no or mild obscuration and those with near complete obscuration in the IXPE band, 2-8 keV.  In the latter case, polarization can be quite large, as the emission is dominated by reflected light from the core off of ionized gas far from the obscuring region.  In all cases, the direction and magnitude of polarization is highly sensitive to the specific geometry of the emission region and the scatterer.  As with AGN, there are obscured X-ray binaries with high, constant polarization, and those that are directly viewed, with weak polarization that relates to disk emission.  A third group of X-ray binaries includes X-ray pulsars, with polarization directly associated with the pulsed emission.
