The inaugural race was held in 2018 and is as the final race of NASCAR's "regular season" for the Xfinity Series. Following the race, the top 12 drivers in points standings advance to the seven-race NASCAR Xfinity Series playoffs.[2] As a playoff race, Monster Energy NASCAR Cup Series drivers are prohibited from competing.[3]

On March 8, 2017 it was announced that Las Vegas Motor Speedway, another SMI track, would get a second Cup date, a second Xfinity date, and a second Truck date. While the Fall Cup race and Truck race at New Hampshire Motor Speedway will go there, Kentucky will lose this race and be moved to Las Vegas.[4]

The new date that Las Vegas Motor Speedway acquired from Kentucky Speedway will become the final race of the regular season to replace the Overton's 300 at Chicagoland Speedway which moves to June.

In 2019, with the announcement of the track's September weekend going prime-time, the race will become a Saturday night event.
