Elucidating the production process of heavy quark bound states is a central goal in heavy-ion collisions [1]. Two central questions exist: Do bound states of heavy quarks form in the early time evolution of the glasma? If so, in which time regime can that happen? An Answer requires the development of a non-perturbative treatment of the real-time-dynamics of heavy quarkonia. Here we present preliminary results from a simulation of bottomonium dynamics in the glasma, based on the concept of quenched, classical statistical simulations for the gauge fields [2]. We employ lattice real-time NRQCD to order $1/(aM_{\text{q}})^2$ to describe the bottomonium evolution [3,4]. By computing the time-evolution of spectral functions of bottomonium-channels we expect to identify the emergence of bound states and their formation time in the evolving glasma. *References* [1] G.
