The stadium officially opened on August 26, 2017, with a Falcons preseason game against the Arizona Cardinals, despite the retractable roof system being incomplete at the time. Several events formerly held at the Georgia Dome moved to Mercedes-Benz Stadium following its completion, including the SEC football championship game and the Peach Bowl. In 2018, it hosted the College Football Playoff National Championship and the MLS Cup (as Atlanta United held home field advantage), and it hosted Super Bowl LIII in 2019.
