The forthcoming optical and radio observatories will, in the next decade or so, probe a large fraction of the whole observable Universe. This will open a new observational window into the study of cosmological observables on ultra-large scales, such as general-relativistic corrections in large-scale structure or the seeds of primordial non-Gaussianity. I will review the prospects for measuring these effects in the context of the Large Synoptic Survey Telescope (LSST) and the Square Kilometre Array (SKA), as well as the observational challenges that must be tackled before such measurements can be carried out.
