Stock car racing events in the NASCAR Xfinity Series has been held at the Homestead–Miami Speedway since the track's inauguration in 1995. For much of its history, it was the final race of the second-tier series' season. The event is currently named Contender Boats 300 for sponsorship reasons; with exception of one-off emergency races in 2020 and a one-off change in 2021, the race has been held as a 300-mile race.

Sam Mayer is the defending winner.

The race at Homestead was added to the then-Busch Series calendar in 1995, and was immediately positioned as the final event of the series' season. Through the 2001 season, the Busch Series was the only one of NASCAR's three major series to end its season at the track. The NASCAR Craftsman Truck Series began racing at the track in 1996 with an early season date, while the NASCAR Cup Series placed the series on its 1999 schedule and gave it the penultimate race date on its schedule.

In 2002, NASCAR began having its season ending weekend at Homestead, with all three series crowning their respective champions at the end of the weekend. The 300 mile event was run on Saturday of that weekend, and carried sponsorship from Ford Motor Company until 2019.

In 2020, the race date was changed to early spring as part of a schedule realignment. Due to the COVID-19 pandemic, the race was moved to June and changed from a single 300-mile race to two races combined for a total distance of 501 miles, replacing a date at Iowa Speedway.^[1] Hooters assumed naming rights for the first race, while Contender Boats, a local boat manufacturer, sponsored the second, a Dash 4 Cash event.^[2][3][4] The Sunday race was originally named the 2020Census.gov 300 as the United States Census was going on at the time of the initially-scheduled date.^[5]

For the 2021 season, the race was originally announced as reverting to its original 300-mile distance with Contender Boats returning as title sponsor,^[6] but it instead remained at 250 miles with 167 laps and the Contender Boats 250 race name.^[7][8]

A NASCAR bulletin that Fox Sports' Bob Pockrass received notes the 300-mile distance will return in 2022.
