Over a five-year period, the Dark Energy Spectroscopic Instrument (DESI) will spectroscopically classify nearly 40 million galaxies and quasars over 1/3 of the sky and to redshifts z < 3.5. The DESI collaboration has completed measurements of the baryon acoustic oscillation (BAO) feature and more generally, of large-scale structure, using data from the first year of observation. In this talk, I will present those measurements and their implications for our understanding of the cosmological model. In particular, I will discuss the constraints on the Hubble Constant, dark energy equation of state, and summed mass of the three neutrino mass eigenstates. In doing so, I will discuss the new and future DESI measurements with respect to the hints of tension that have been reported in the Hubble Constant and with LCDM in general.
