The NASCAR Cup Series leaves California after its two‑race swing through Naval Base Coronado and Sonoma Raceway and heads to the Midwest for its first visit to Chicagoland Speedway since 2019. Sunday’s race marks the second leg of the 2026 In‑Season Challenge and brings the series back to a 1.5‑mile oval that once served as a summer staple before falling off the schedule for seven years.

Alex Bowman arrives in Joliet with momentum after knocking out No. 1 seed Tyler Reddick in the opening round of the Challenge. Bowman is also the most recent Chicagoland winner, having captured the track’s last Cup event in 2019. His Round 2 matchup with Austin Cindric is one of several heavyweight pairings that will shape the bracket.

Hendrick Motorsports teammates Kyle Larson and William Byron will square off, while Joe Gibbs Racing’s Ty Gibbs and Chase Briscoe meet in a duel between two of the sport’s most aggressive young drivers. Corey Heim returns to the No. 67 Toyota for 23XI Racing just over a week removed from scoring his first career Cup Series win at Naval Base Coronado.

Heim enters Chicagoland with an average finish of 14.8 through his limited starts and has quickly become one of the season’s biggest surprises. JJ Yeley also rejoins the field, bringing the entry list to thirty‑eight cars for the weekend. The grid includes a wide range of experience, from nineteen‑year‑old Connor Zilisch to forty‑nine‑year‑old Yeley, and features multiple former Chicagoland winners including Bowman, Larson, and Keselowski.

The track itself adds a layer of unpredictability. Chicagoland has not been repaved since opening in 2001, leaving a surface that produces significant tire falloff and forces drivers to manage grip over long green‑flag stretches. The last Cup race here averaged 143.1 mph and featured a winning margin of just 0.546 seconds, a reminder that even on worn asphalt, the closing laps tend to tighten.

The preferred groove typically shifts toward the wall as rubber builds up, and teams expect a race defined by throttle discipline, tire conservation, and the ability to maintain pace over thirty‑lap runs. Several drivers enter the weekend with compelling statistical trends. Larson has led 824 laps this season and carries an average finish of 8.9 into Chicagoland, making him one of the strongest performers on intermediate tracks.

Byron has three wins and ten top‑tens, while Gibbs has posted an average finish of 10.7 and continues to climb the standings after returning from injury. Briscoe, meanwhile, enters with a 12.4 average finish and remains one of the most efficient long‑run drivers in the field. Reddick, despite his early Challenge exit, has four wins and the best average finish among full‑time drivers at 7.3.

Chicagoland’s return comes at a pivotal moment in the season. The In‑Season Challenge has added a new layer of urgency to mid‑summer racing, and the bracket matchups ensure that every lap carries consequences beyond the traditional points battle. Bowman’s upset win, Heim’s breakthrough victory, and Larson’s steady consistency have reshaped the competitive landscape heading into July.

With thirty‑eight cars on a worn, multi‑groove oval, the race is likely to reward patience, punish overreach, and produce the kind of late‑race drama that defined Chicagoland’s earlier years. Fans can watch the NASCAR Cup Series return to Chicagoland Speedway on Sunday at 6 p.m. ET on TNT Sports and HBO Max, with radio coverage from MRN and SiriusXM NASCAR Radio.
