NASCAR In-Season Challenge seeding and matchups set for Sonoma race
NASCAR will host its second annual In-Season Challenge from June 28 to July 26, featuring a single-elimination bracket of the top 32 Cup Series drivers competing for a $1 million prize. The tournament spans five tracks, including Sonoma, Chicagoland, Atlanta, North Wilkesboro, and Indianapolis.
The seedings for the event were finalized following the Pocono race on June 14. According to the tournament format, the driver with the better finish in each head-to-head pairing advances to the Round of 16, continuing until two racers remain for the championship race at the Brickyard.
How does the NASCAR In-Season Challenge work?
The competition uses a bracket system based on Cup Series standings. The No. 1 seed, Tyler Reddick, is paired against the No. 32 seed, Alex Bowman, in the opening round at Sonoma. This process of elimination repeats over a five-week stretch.

The winner of the final race at Indianapolis receives the $1 million prize. Last year, Ty Gibbs won the tournament by defeating Ty Dillon, who was the final driver to qualify for the field.
Which drivers are paired for the first round?
The opening round matchups are as follows:
- No. 1 Tyler Reddick vs. No. 32 Alex Bowman
- No. 16 Austin Cindric vs. No. 17 Brad Keselowski
- No. 8 Daniel Suarez vs. No. 25 Todd Gilliland
- No. 9 Carson Hocevar vs. No. 24 Zane Smith
- No. 12 Chase Briscoe vs. No. 21 AJ Allmendinger
- No. 5 Ty Gibbs vs. No. 28 Austin Dillon
- No. 13 Bubba Wallace vs. No. 20 Michael McDowell
- No. 4 Chase Elliott vs. No. 29 Noah Gragson
- No. 2 Denny Hamlin vs. No. 31 Ty Dillon
- No. 15 Erik Jones vs. No. 18 Joey Logano
- No. 7 Chris Buescher vs. No. 26 John Hunter Nemechek
- No. 10 Christopher Bell vs. No. 23 Ross Chastain
- No. 11 William Byron vs. No. 22 Ricky Stenhouse Jr.
- No. 6 Kyle Larson vs. No. 27 Riley Herbst
- No. 14 Shane van Gisbergen vs. No. 19 Ryan Preece
- No. 3 Ryan Blaney vs. No. 30 Josh Berry
Why is Denny Hamlin concerned about the opening round?
Denny Hamlin enters the challenge on a streak of three straight victories, including his June 14 win at Pocono. However, he expressed concern regarding the first round at Sonoma, stating, āIām cooked,ā while laughing.
Hamlin’s comment follows a history of struggling on road courses like Sonoma. Additionally, Ty Dillon, his first-round opponent, upset Hamlin in the first round of the previous year’s challenge.
What could happen next in the tournament?
The first round of competition may result in further upsets if top-seeded drivers struggle on the road course at Sonoma. If Ty Dillon repeats his performance from last year, Hamlin could be eliminated early despite his current winning streak.
The remaining 16 drivers will then move through the bracket across Chicagoland, Atlanta, and North Wilkesboro. This progression is likely to narrow the field before the final championship showdown at Indianapolis.
