As expected, O’Reilly Auto Parts has been officially announced as the successor to Xfinity as the title sponsor of NASCAR’s second-tier division in the NASCAR National Series ranks beginning in 2026. O’Reilly will take over as the title sponsor of the series after an 11-year run for Xfinity as the title sponsor.
A bold new chapter is about to be written.

“Like the great sport of NASCAR, O’Reilly Auto Parts was born in America and built on the hard work and drive of passionate people,” said NASCAR President Steve O’Donnell. “This new partnership allows us to continue to fuel that passion for the next generation of NASCAR’s stars and fans while celebrating the journey we’ve been on together for decades.”
O’Reilly Auto Parts will officially become the fourth company to hold the title sponsorship of the series when it assumes the naming rights on January 1, 2026. Prior to Xfinity, the series was sponsored by Nationwide Insurance from 2008 to 2014, and the Anheuser-Busch Brewing Company served as the title sponsor from 1982 to 2007.
For O’Reilly Auto Parts, the partnership with NASCAR makes sense as the company shares key values with the defining characteristics of the sport.
“Our company is rooted in the same values that define NASCAR—teamwork, enthusiasm, and dedication,” said O’Reilly Auto Parts President Brent Kirby. “You’ll see those in action when our customers walk through our doors. We know they need fast service, and Team O’Reilly will get them the parts they need quickly, with excellent customer service. We welcome all fans to stop by our stores and see how our team can help keep them running.”
The CW will once again carry the entire season of races for the NASCAR O’Reilly Auto Parts Series in 2026, marking the second of seven seasons for the broadcasting network in its current media rights agreement with NASCAR. Year-over-year viewership for the NASCAR Xfinity Series is currently up 17% from a season ago, and the 2025 season is trending toward being the most-watched season since the 2018 season.
