%X DarkSide (DS) at Gran Sasso underground laboratory is a direct dark matter search program based on TPCs with liquid argon from underground sources. The DS-50 TPC, with 50 kg of liquid argon is installed inside active neutron and muon detectors. DS-50 has been taking data since Nov 2013, collecting more than 10<sup>7</sup> events with atmospheric argon. This data represents an exposure to the largest background, beta decays of <sup>39</sup>Ar, comparable to the full 3 y run of DS-50 with underground argon. When analysed with a threshold that would give a sensitivity in the full run of about 10<sup>−45</sup> cm<sup>2</sup> at a WIMP mass of 100 GeV, there is no <sup>39</sup>Ar background observed. We present the detector design and performance, the results from the atmospheric argon run and plans for an upscale to a multi-ton detector along with its sensitivity.
