Effective Field Theory (EFT) constitutes a consistent theoretical framework to look for deviations from the Standard Model (SM) in the absence of light new physics. Within the EFT, different sectors become correlated and global interpretations of measurements become necessary. I will present the results of an updated global SMEFT analysis of Higgs, top quark, and diboson production data from the LHC, complemented by electroweak precision observables (EWPOs) from LEP and SLD. I will then discuss the impact of HL-LHC measurements on the SMEFT parameter space, through dedicated projections extrapolating from LHC Run II data. Finally I will explore the significant constraints that measurements from two proposed high-energy circular colliders, the FCC-ee and the CEPC, would impose on both the SMEFT parameter space and on representative UV-complete models.
