In this article, we review and update implications of the muon anomalousmagnetic moment (muon $g-2$) anomaly for two-Higgs-doublet models (2HDMs),which are classified according to imposed symmetries and their resulting Yukawasector. In the minimal setup, the muon $g-2$ anomaly can be accommodated by thetype-X (lepto-philic) 2HDM, flavor-aligned 2HDM (FA2HDM), muon-specific 2HDM($\mu$2HDM), and $\mu\tau$-flavor violating 2HDM. We summarize all relevantexperimental constraints from high-energy collider experiments and flavorexperiments, as well as the theoretical constraints from the perturbativeunitarity and vacuum stability bounds, to these 2HDMs in light of the muon$g-2$ anomaly. We clarify the available parameter spaces of these 2HDMs andinvestigate how to probe the remaining parameter regions in future experiments.In particular, we find that, due to the updated $B_s\to\mu^+ \mu^-$measurement, the remaining parameter region of the FA2HDM is almost equivalentto the one of the type-X 2HDM. Furthermore, based on collider simulations, wefind that the type-X 2HDM is excluded and the $\mu$2HDM scenario will becovered with the upcoming Run 3 data.
