The race was first run in 1999 as the Outback Steakhouse 200. It became the Bashas' Supermarkets 200 in 2002. Following realignment of the two Xfinity Series races, the Arizona 200 took over the November slot. Austin Cindric is the most recent winner of the event.
The 2016 race was held at night and serves as the sixth race of the NASCAR Xfinity Series playoffs.
In early 2021 it was announced that the race, which is the season finale, will be held at night in the same manner as the Truck event.
