The four general purpose detectors on the Tevatron (CDF, D0) and LHC (Atlas, CMS) hadron colliders continue to make important measurements in the field of CP violation (CPV) in B hadron physics. The CDF collaboration presents new results in direct CPV of charmless B decays, providing world-leading measurements in b baryon decays, and finding evidence for non zero CPV in the decay Bs0 → K−π+. The D0 Collaboration presents measurements of the semileptonic mixing asymmetries in B0 and Bs0 mesons, with the former having a precision exceeding the previous world average. All four experiments perform time-dependent angular analysis of the decay Bs0 → J/ψϕ enabling the extraction of the lifetime difference ΔΓs and the CPV phase ϕsJ/ψϕ. In all cases, the results obtained are consistent with each other, and with the standard model predictions.
