DarkSide-50 aims to perform background-free WIMP searches with active vetos of a 30-tonne liquid scintillator neutron veto and a 1k-tonne water Cherenkov muon veto. DarkSide-50 has been taking data with underground Ar, which is significantly depleted in radioactive <sup>39</sup>Ar, and measured its depletion factor. The result of WIMP searches with 70 live-days of underground argon data will be presented. Also recent study of the liquid scintillator veto's performance and the future plan will be discussed.
