The correlations of electric currents in hot non-Abelian plasma areresponsible for the experimental manifestations of the chiral magnetic effect(CME) in heavy-ion collisions. We evaluate these correlations using holography,and show that they are driven by large-scale topological fluctuations. In anon-Abelian plasma with chiral fermions, local axial charge can be generatedeither by topological fluctuations (creating domains with nonzero Chern-Simonsnumber) or by thermal fluctuations. Within holography, we investigate thedynamical creation of the axial charge and isolate the imprint of thetopological dynamics on the spatial correlations of electric current. Inparticular, we show that the spatial extent of the current correlation is quitelarge ($\sim 1\ {\rm fm}$) and grows with time, which is consistent withsphaleronlike dynamics. We provide numerical estimates for this spatial sizethat can be used as an input in phenomenological analyses.
