Recent measurement of the time-dependent CP violating weak phase in $B_s^{0}\rightarrow J/\psi \phi$ decay using proton-proton collision data collected by the ATLAS detector at a center-of-mass energy of 13 TeV corresponding to integrated luminosity of 80.0 fb$^{-1}$ is presented. After combining the results with those from 19.2 fb$^{-1}$ of 7 TeV and 8 TeV data, the value of CP-violating phase is $\phi_{s}$ = -0.087 $\pm$ 0.036 (stat.) $\pm$ 0.021 (syst.) rad.
