  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, $b\to s$ flavor changing neutral currents, and $Z\to b\bar b$ 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 $b\to s$ transitions. In the fit, we find strong synergies
between top-quark and beauty physics that allow to tighten constraints on
various coefficients.
