2026 Eero 400 Prediction & Race Preview In the NASCAR Cup Series - 7/5/2026

NASCAR is rolling the Cup Series into territory none of the current Next Gen field has ever raced on a points day, and that alone makes the eero 400 one of the most intriguing races of the summer. Chicagoland Speedway welcomes the series back after a seven-year layoff, the points race is tighter than it has been all season, and the second round of the In-Season Challenge bracket adds an extra layer of intrigue for this event. Denny Hamlin grabbed the championship lead by a single point over Tyler Reddick at Sonoma, and now both former teammates head into a venue where a lack of recent history offers almost no data to rely on.
Hamlin enters Joliet as the hottest driver in the field, having won three of the last five points races and taken over the points lead by a single point after Sonoma. He has been the most consistent qualifier and closer on intermediate ovals all season, and Chicagoland's 1.5-mile, D-shaped layout with 18 degrees of banking in the turns plays to the same strengths he has shown at Las Vegas, Kansas, and Charlotte this year. The lack of current-car data at this track keeps this from being a 4 or 5 star play, since practice and qualifying speeds on Friday and Saturday will carry more weight than usual, but Hamlin's overall season form makes him the option to build around.
Kyle Larson and William Byron loom as the drivers most likely to spoil that outcome as far as I'm concerned. Larson has a strong history on 1.5-mile tracks throughout his career, and Byron is always a threat as well. Watch practice speeds closely on Friday, as this is a track where a handful of laps in final practice could move the board more than anything else.
Combined odds: +3519
This parlay leans on three separate storylines colliding at the same track. Hamlin is the form pick given his points lead and recent win total. Bowman is the sentimental and statistical angle in this parlay. He is the last driver to win a Cup race at Chicagoland, scoring his first career victory there in 2019, and he just knocked Tyler Reddick out of the In-Season Challenge bracket at Sonoma by finishing 10th while Reddick fell to last. A driver returning to the scene of his breakthrough win, fresh off advancing in the bracket, is the kind of value leg that turns a 3-leg ticket into a real payout. Larson rounds out the parlay as the safety net. He is a top-5 threat virtually anywhere there is sustained speed and grip, and 1.5-mile ovals have historically been his bread and butter.
The eero 400 marks the Cup Series' first points race at Chicagoland Speedway since June 30, 2019, when Alex Bowman held off Kyle Larson for his first career win in a rain-shortened, weather-delayed Camping World 400. That seven-year absence means none of the current Next Gen cars have ever turned a lap on the 1.5-mile Joliet, Illinois oval in race conditions, which adds a layer of unpredictability to a series that has otherwise settled into very familiar patterns at its intermediate-track stops this season.
Sunday's race is also round 2 of NASCAR's 32-driver In-Season Challenge bracket. Top seed Tyler Reddick was eliminated at Sonoma after a power steering failure left him a multi-lap loser, with his 32nd-seeded first-round opponent, Bowman, advancing on the strength of a 10th-place run. Hamlin survived his own messy day, getting spun by Carson Hocevar and finishing 26th, but moved on when his opponent, Ty Dillon, also suffered a late mechanical issue. Heading into Chicagoland, Hamlin now leads the championship standings by a single point over Reddick, 719 to 718, with Ryan Blaney a distant third at 615.
The win at Sonoma went to Shane van Gisbergen, who held off Chase Briscoe by 0.357 seconds for his eighth career Cup Series victory and second of 2026. Ty Gibbs swept both stages from the pole, while Kyle Larson quietly turned in his fourth consecutive top-5 finish to remain solidly inside the top 5 in points. With the four scheduled road courses of the regular season now complete, the slate turns back to ovals for the stretch run, and Chicagoland's return gives teams a fresh puzzle to solve with stage breaks set at lap 80 and lap 165 across a 267-lap, 400.5-mile distance.
Manufacturer trends from the track's history favor whichever camp builds the better short-run speed. Toyota drivers Hamlin and Reddick have been the class of the field for two months, but Chevrolet's recent form through Larson, Byron, and Elliott means this is shaping up as an unpredictable race between the top two manufacturers rather than a one-sided affair.
