We will discuss how the Euclid and WFIRST space surveys will revoluzionize our understanding of large-scale structure during the epoch when the knots of the cosmic web first start forming. Our predictions are based on recent results from current optical and infrared surveys with the Hubble Space Telescope (HST). Imaging and grism spectroscopy obtained by the HST CANDELS (Grogin et al. 2011; Koekemoer et al. 2011) and CARLA (Wylezalek et al. 2013) surveys are giving us our first glimpse of large-scale structure formation at z>1.5 from these small samples. We are able to study the formation of clusters and proto-clusters and of the progenitors of the most massive galaxies in the Universe. These new observations enable us to optimize the study of large-scale structure at these high redshifts with Euclid and WFIRST.
