The NASCAR In‑Season Challenge is back for its second edition, bringing a bracket‑style tournament to TNT Sports over five weeks of head‑to‑head matchups.
The competition will culminate on July 26 at the iconic Brickyard 400, where the final two drivers will battle for a $1 million prize that, while separate from the championship, could shift on‑track strategies.
Last year’s champion, Ty Gibbs, earned the cash by defeating Ty Dillon in the finals, a result that added a new layer of intrigue to the series.
Although the challenge does not affect the official standings, the format encourages drivers to race each other with fresh incentives, and the seeding for the opening round is determined by points earned after the Pocono weekend.
Round 1 at Sonoma
The first set of pairings unfolds on the winding road course at Sonoma Raceway in California, featuring a lineup that includes Tyler Reddick versus Denny Hamlin, Ryan Blaney against Josh Berry, and many other high‑profile matchups.
Fans can expect a mix of veteran talent and rising stars, with names such as Chase Elliott, Kyle Larson, Christopher Bell and Bubba Wallace all slated to compete in the opening bracket.
The stakes go beyond prize money; a strong performance can influence momentum heading into the summer stretch and affect how drivers approach subsequent races.
With the championship still up for grabs, the In‑Season Challenge adds a compelling narrative to the 2026 schedule, promising twists, rivalries and moments that could define the season.
