Abstract: Recently there has been considerable progress in the experimental determination of the Bs mixing phase. Data from the Tevatron seem to point towards large CP violation in Bs mixing at the level of 3 sigma above the tiny SM prediction. I will briefly review the current experimental status and then discuss if and how large CP violation in Bs mixing can be accommodated for in various supersymmetric models, including the MSSM with Minimal Flavor Violation and supersymmetric flavor models that show representative flavor structures in the soft SUSY breaking terms.
