Chicagoland Is Back. So Is Kyle Larson.

Cup racing hasn't been to Chicagoland since June 30, 2019, when Alex Bowman won his first career race there. Seven years is a long time for a track to sit mostly dormant, and it shows. The surface has a big dip diving into Turn 1 and a bump running through the center of 3 and 4, and drivers who tested it this spring say the racing line is going to move around all weekend. Add in July heat slowing the pace, and Sunday night's eero 400 is as much of an unknown as a Cup points race gets in 2026.

That uncertainty is exactly why we like where our numbers point. Our sim, the Monte Carlo projection engine that runs every Cup race thousands of times before the green flag, has a clear read on the one story that matters most this weekend: Kyle Larson.

1. The Larson Case

Kyle Larson

Larson hasn't won a points race since Kansas on May 11, 2025. That's 42 races and counting, and it's been long enough that he spent the back half of last season and the start of this one as one of the sport's most popular fades. Sunday is start number 43.

Here's what the fade misses. His last four finishes: 4th at Sonoma, 3rd at San Diego, 5th at Pocono, 4th at Michigan. That is not a driver in a slump. That's a driver deep in a run, which will be obvious in hindsight.

On our Heat Check, which tracks each driver's last-5 average finish against his season average, Larson is the second-hottest driver in Cup right now at plus-6.1, behind only Chase Briscoe's plus-7.2.

More telling is our Snakebit Index. It measures how much better a driver runs than he finishes, and Larson is tied with Christopher Bell for the most snakebit driver in Cup: he posts the series-best average running position at 10.7 against only the 7th-best average finish. The results have been undercutting the speed for a year. The speed has been elite the whole time.

Track history backs it up. Larson has 4 top-5s in 6 Cup starts at Chicagoland, with back-to-back runner-up finishes in 2018 and 2019. He was also one of three drivers who got real laps on the actual Chicagoland surface this year, driving the Chevrolet in April's Goodyear tire test.

2. The Experience Divide

Eighteen of the 39 drivers entered Sunday have never made a Cup start at Chicagoland: Tyler Reddick, Christopher Bell, Chase Briscoe, Ty Gibbs, Austin Cindric, Corey Heim, Carson Hocevar, Shane van Gisbergen, Connor Zilisch, Josh Berry, Noah Gragson, John Hunter Nemechek, Riley Herbst, Zane Smith, Austin Hill, Cole Custer, Todd Gilliland and Cody Ware. Worth flagging: several of them raced there in lower series years ago, just never in a Cup car.

Only three drivers got real preparation. Larson, Denny Hamlin and Ryan Blaney spent two full days on the surface together in April's tire test, one per manufacturer.

Denny Hamlin

Hamlin is the elephant in this field. Fourteen career Chicagoland starts, the most of anyone entered, a win there in 2015, and top-10s in five of his last six visits. He just took the Cup points lead for the first time this season, by a single point over Tyler Reddick, who drives for the 23XI Racing team Hamlin co-owns. Our model makes Hamlin the outright favorite this weekend: median 5th place across 10,000 sims, 22% win probability, 37 projected laps led, $11,000 on DraftKings.

The catch is everyone sees the same numbers we do. Hamlin projects at 38% ownership, the chalkiest name on the slate. Larson, by contrast, projects almost as well (median 5th, 17.6% win probability, $10,500) at 33.8% ownership. Same ceiling, cheaper salary, less company in your lineup.

3. The Buy-Low and the Fade: Byron vs. Gibbs

William Byron

Byron is cold right now, the 8th-coldest driver in Cup on our Heat Check. But his best track type is exactly what Chicagoland is: a big, fast oval. His last five races on that track type: 18th at Michigan, then 9th at Charlotte, 8th at Texas, and 7th and 9th at the last two Kansas races, and he gained positions in every one of those besides Michigan.

Ty Gibbs

Gibbs is the mirror image. He's been genuinely hot lately, but big fast ovals are his worst track type, and the same five races prove it: 25th at Michigan, 6th at Charlotte, 36th at Texas, and 9th and 25th at the last two Kansas races. He lost positions in every single one of those, including the two where he actually finished top-10.

Big fast ovals, last 5	Michigan	Charlotte	Texas	Kansas 1	Kansas 2
William Byron	18th	9th	8th	7th	9th
Gained positions in all 4 non-Michigan races
Ty Gibbs	25th	6th	36th	9th	25th
Lost positions in all 5, including both top-10s

The model likes the buy-low on Byron if he qualifies average: projected 10th, $9,700 on DraftKings, just 17.6% ownership, the best leverage number among any of the big names in the field. Gibbs projects 12th at $9,000 with 19.5% ownership, owned like a top-10 lock and priced like one, at the exact track type where the numbers say he doesn't belong. That's the fade.

4. The Briscoe Problem

Chase Briscoe

Briscoe is the hottest driver in Cup right now, plus-7.2 on our Heat Check. But on big fast ovals, he's a coin flip.

Top-5 or 20th-plus, almost nothing in between. That makes him fine for GPP lineups, where the ceiling pays for the variance, and dangerous for cash. He's $9,900 on DraftKings, projected 10th, 21.1% owned.

5. The Honest Bit

Our number-one projected driver has finished top-10 in 17 of 19 races this season, with 11 wins on that call. Last week at Sonoma, we made Shane van Gisbergen the top pick and he won. In that same race, we also had Tyler Reddick 4th on the board, and he finished 36th.

Here's the part we're not going to hide: the model still has Reddick 3rd on the board at Chicagoland, median 5th with a 74% top-10 probability, even though he's the second-coldest driver in Cup on our Heat Check and has never turned a Cup lap at this track. Sometimes the model is seeing speed the results haven't shown yet. Sometimes it's just wrong. We show it either way.

6. The Weekend

The full board is live for both Chicagoland races: the O'Reilly Series Saturday at 5:30 PM ET, Cup Sunday at 6:00 PM ET. Qualifying is Saturday at 3:00 PM ET, and Saturday is carrying a 75 to 80 percent storm risk, so keep an eye on the schedule if you're building around qualifying position. Sunday looks a lot better: 83 degrees, a 35% chance of early showers that improves as the evening goes on.
