XENON100 is the current phase of the XENON dark matter program, which aims for the direct detection of WIMPs with liquid xenon time-projection chambers. It will be presented the status of the experiment after 224.6 live days taken in 2011 and 2012 during which the detector successfully improved in terms of more calibration data, higher xenon purity, lower threshold and better background removal. The analysis has yielded no evidence for dark matter interactions. In parallel to the operations of XENON100, the Collaboration has already designed the next generation detector, XENON1T, with a fiducial mass of about 1 ton and a total mass of 2.4 tons, with the goal of having a sensitivity two orders of magnitude higher than its predecessor. The status of XENON1T detector will be described.
