Abstract	The potential for future measurements of CP violation using the decay B0s → J/ψφ at ATLAS is discussed. Simulations of future detector layouts and expected LHC conditions at increasing luminosity are used to derive statistical precisions on the weak phase φs for the three data taking periods 2015-2017, 2019-21 and 2023-30+.
