The 2025 BetMGM 300 was the 13th stock car race of the 2025 NASCAR Xfinity Series, and the 44th iteration of the event. The race was held on Saturday, May 24, 2025, in Concord, North Carolina at Charlotte Motor Speedway, a 1.5 miles (2.4 km) permanent asphalt tri-oval shaped intermediate speedway. The race was originally scheduled to be contested over 200 laps, but was increased to 205 due to an overtime finish. In a wreck-filled race that occurred in the final stage, William Byron, driving for Hendrick Motorsports, would survive numerous late-race restarts and took advantage of newer tires, making a late race pass on Justin Allgaier with two laps to go to earn his fifth career NASCAR Xfinity Series win, and his first of the season. Byron dominated the early stages of the race, winning both stages and leading 71 laps, while Allgaier dominated the final portion, leading a race-high 103 laps. To fill out the podium, Connor Zilisch, driving for JR Motorsports, and Nick Sanchez, driving for Big Machine Racing, would finish 2nd and 3rd, respectively.
Sammy Smith, who originally finished in 5th, was disqualified after post-race inspection after failing to meet minimum weight requirements and was credited with a 38th place finish.
