  The in-medium color potential is a fundamental quantity for understanding the
properties of the strongly coupled quark-gluon plasma (sQGP). Open and hidden
heavy-flavor (HF) production in ultrarelativistic heavy-ion collisions (URHICs)
has been found to be a sensitive probe of this potential. Here we utilize a
previously developed quarkonium transport approach in combination with insights
from open HF diffusion to extract the color-singlet potential from experimental
results on $\Upsilon$ production in URHICs. Starting from a parameterized trial
potential, we evaluate the $\Upsilon$ transport parameters and conduct
systematic fits to available data for the centrality dependence of ground and
excited states at RHIC and the LHC. The best fits and their statistical
significance are converted into a temperature-dependent potential. Including
nonperturbative effects in the dissociation rate guided from open HF
phenomenology, we extract a rather strongly coupled potential with substantial
remnants of the long-range confining force in the QGP.
