The Brickyard 400 is an annual NASCAR Cup Series points race held at the Indianapolis Motor Speedway in Speedway, Indiana. The inaugural race was held in 1994 and was the first race other than the Indianapolis 500 to be held at the Indianapolis Motor Speedway since 1916. In its inaugural running, the Brickyard 400 became NASCAR's most-attended event, drawing an estimated crowd of more than 250,000 spectators. The race also paid one of NASCAR's highest purses. From 1994 to 2020, the race was held on the 2.5-mile oval, for a distance of 400 miles. The race was put on hiatus for three years (2021–2023) in favor of the Verizon 200 at the Brickyard which was run on a combined road course and run a distance of 200-mile (321.869 km). However, the race will return to the oval for the 2024 season.

The NASCAR Cup Series is the top racing series of the National Association for Stock Car Auto Racing (NASCAR). The series began in 1949 as the Strictly Stock Division, and from 1950 to 1970 it was known as the Grand National Division. In 1971, when the series began leasing its naming rights to the R. J. Reynolds Tobacco Company, it was referred to as the NASCAR Winston Cup Series (1971–2003). A similar deal was made with Nextel in 2003, and it became the NASCAR Nextel Cup Series (2004–2007). Sprint acquired Nextel in 2005, and in 2008 the series was renamed the NASCAR Sprint Cup Series (2008–2016). In December 2016, it was announced that Monster Energy would become the new title sponsor, and the series was renamed the Monster Energy NASCAR Cup Series (2017–2019). In 2019, NASCAR rejected Monster's offer to extend the naming rights deal beyond the end of the season. NASCAR subsequently announced its move to a new tiered sponsorship model beginning with the 2020 season similar to other U.S. based professional sports leagues, where it was simply known as the NASCAR Cup Series, with the sponsors of the series being called Premier Partners. The four Premier Partners are Busch Beer, Coca-Cola, GEICO, and Xfinity.
