To study the high-energy spin dynamics in hadronic processes probed at the future Electron-Ion Collider, one has to calculate the sub-eikonal corrections and apply the Operator Product Expansion in terms of infinite Wilson line operators. I present the extension of the OPE to include spin dynamics and the non-linear helicity evolution equations for $g_1$ structure-function.
