We present constraints on Wilson coefficients from a combined fit to data from top-quark and beauty-physics measurements within the Standard Model effective field theory. We consider present data on top-quark pair production and decay, b→ s flavor changing neutral currents, and Z→ b b decay, as well as different future scenarios. These comprise projections for HL-LHC, Belle II, and a lepton collider using the example of CLIC. We investigate opportunities for detecting deviations from the Standard Model hinted at by present data on b→ s transitions. In the fit, we find strong synergies between top-quark and beauty physics that allow to tighten constraints on various coefficients.
