  The Galactic Center Gamma-Ray Excess has a spectrum, angular distribution,
and overall intensity that agree remarkably well with that expected from
annihilating dark matter particles in the form of a $m_X \sim 50 \, {\rm GeV}$
thermal relic. Previous claims that these photons are clustered on small
angular scales or trace the distribution of known stellar populations once
appeared to favor interpretations in which this signal originates from a large
population of unresolved millisecond pulsars. More recent work, however, has
overturned these conclusions, finding that the observed gamma-ray excess does
{\it not} contain discernible small scale power, and is distributed with
approximate spherical symmetry, not tracing any known stellar populations. In
light of these results, it now appears significantly more likely that the
Galactic Center Gamma-Ray Excess is produced by annihilating dark matter.
