Using deep Hubble and Spitzer observations Oesch et al. (2016) haveidentified a bright ($M_{\rm UV}\approx -22$) star forming galaxy candidate at$z \approx 11$. The presence of GN-$z11$ implies a number density $\sim10^{-6}\,{\rm Mpc^{-3}}$, roughly an order of magnitude higher than theexpected value based on extrapolations from lower redshift. Using theunprecedented volume and high resolution of the BlueTides cosmologicalhydrodynamical simulation, we study the population of luminous rare objects at$z > 10$. The luminosity function in BlueTides implies an enhanced number ofmassive galaxies, consistent with the observation of GN-$z11$. We find about 30galaxies at $M_{\rm UV}\approx -22$ at $z = 11$ in the BlueTides volume,including a few objects about 1.5 magnitudes brighter. The probability ofobserving GN-$z11$ in the volume probed by Oesch et al. (2016) is $\sim 13$ percent. The predicted properties of the rare bright galaxies at $z = 11$ inBlueTides closely match those inferred from the observations of GN-$z11$.BlueTides predicts a negligible contribution from faint AGN in the observedSED. The enormous increase in volume surveyed by WFIRST will provideobservations of $\sim1000$ galaxies with $M_{\rm UV} < -22$ beyond $z = 11$ outto $z = 13.5$.
