Numerous astrophysical measurements indicate that much of our universe is made of an undiscovered type of matter, termed 'Dark Matter'. The axion is a hypothetical particle that is a well-motivated candidate for dark matter inspired by the Peccei-Quinn solution to the Strong-CP problem in Nuclear Physics. After decades of work, the US DOE flagship axion dark matter search, ADMX G2, is the first experiment to be sensitive to plausible DFSZ coupling model of dark matter axions, in part due to the addition of superconducting quantum-limited amplifiers. ADMX G2 has begun to search the theoretically-favored axion mass region 2-40 micro-eV, and could now discover dark matter at any time. This presentation will report the first results from exploring the range around 2.7 micro-eV last year (2018), discuss this year's (2019) operations and review the ADMX G2 plans to continue the search to cover the entire mass range.
