In this proceeding, we present a summary of the latest CP-violation findings at LHC.
We begin with an overview of $\gamma$ measurements in $B^{\pm} \rightarrow D h^{\pm}$ decays with data collected in 2015-2018 by LHCb and the update on the $\gamma$ combination from LHCb.

Next, an updated time-integrated CP asymmetry in $D^{0}\rightarrow K^{+}K^{-}$ decays with the 2015-2018 LHCb data sample is shown.
In combination with the difference of time-integrated asymmetries, direct CP-asymmetries in $D^{0}\rightarrow K^{+}K^{-}$ and $D^{0}\rightarrow \pi^{+}\pi^{-}$ decays are determined.

Additionally, we present the updated time-dependent CP-violation measurements of angles $\beta$ from $B^0\rightarrow \psi K^0_S$ and $\beta_s$ from $B_s^0 \rightarrow J/\psi K^+K^-$ decays with 2015-2018 LHCb data sample.
We also show the new measurement of CP-violating phase $\phi_s^{s\overline{s}s}$ in $B_s^{0} \rightarrow \phi \phi$ transitions with 2015-2018 LHCb data.

The new results are the world's best estimates of $\beta$, $\beta_s$ angles, $\phi_s^{s\overline{s}s}$ phase, CP-symmetry in $D^{0}\rightarrow K^{+}K^{-}$ and $D^{0}\rightarrow \pi^{+}\pi^{-}$ decays and the most precise determination of $\gamma$ angle from a single experiment.
Finally, we briefly outline the future prospects of CP-violation measurements at LHC.
