The NASCAR Cup Series rolls into Joliet, Illinois this weekend for the eero 400, and for the first time since 2019 the series will turn laps on the 1.5-mile oval at Chicagoland Speedway instead of the downtown street circuit that hosted the last three summers of racing. The Cup field practiced Friday, qualified Saturday and lines up Sunday, July 5, for a 6 p.m. ET green flag broadcast on TNT Sports, capping a three-day weekend that also includes an ARCA Menards Series race and a NASCAR O’Reilly Auto Parts Series event on the same 1.5-mile layout.
From City Blocks Back to a Familiar Oval
Chicago’s street race, which ran through Grant Park from 2023 through 2025, will not return in 2026. NASCAR opted to pause the event rather than run it a fourth straight year, citing the need to work with city officials on a new date and a more efficient operational plan after downtown closures around the Fourth of July repeatedly bumped into local traditions like the Taste of Chicago. Rain delays in multiple years and the exit of founding sponsor McDonald’s after a two-year deal added to the case for a reset. NASCAR has pointed to 2027 as a target for a Chicago streets comeback, while a new street event in San Diego fills the void on this year’s schedule. In the meantime, Chicagoland Speedway, dormant since a rain-soaked 2019 date, gets the market’s Cup Series slot back. Full session times and results are being tracked on NASCAR’s official weekend hub.
The swap says as much about scheduling logistics as it does about racing product. Street courses draw a different crowd and a different broadcast look than a banked 1.5-mile tri-oval, and NASCAR has spent the past few seasons testing how much variety its calendar can absorb without losing the ovals that built the sport. Chicagoland was one of the cookie-cutter 1.5-milers built in the intermediate-track boom of the early 2000s, and its return lets teams lean on a deep well of setup data that a temporary street circuit could never offer.
What’s Actually at Stake This Weekend
Beyond the novelty of the venue, the eero 400 doubles as the second round of the 2026 In-Season Challenge, the bracket-style side competition that pays its eventual winner $1 million. It also lands at a pivotal moment in the points race. Denny Hamlin took over the regular-season points lead for the first time all year after Sonoma, edging Tyler Reddick by a single point, 719 to 718, with both drivers chasing the kind of consistency that a fresh oval date can easily scramble. A strong run at Chicagoland would let either driver open real breathing room heading into the second half of the regular season, while a stumble could hand the lead right back.

A Track With Its Own Ledger
Chicagoland’s history offers a useful data point for anyone wondering whether the oval can match the street race’s buzz. The venue’s last Cup date, in June 2019, produced one of the tightest finishes in track history: Alex Bowman held off Kyle Larson by just 0.546 seconds to score his first career Cup win, a margin thin enough to remind teams that 1.5-mile racing at Chicagoland has never been a fuel-mileage snooze. Tony Stewart is the track’s winningest driver with three victories there, in 2004, 2007 and 2011, while Kevin Harvick, Brad Keselowski, Martin Truex Jr. and Kyle Busch each won twice, a list that reads like a cross-section of NASCAR’s last two decades of contenders.
The street race, for its part, had been trending the wrong way at the box office before its pause. Television audiences slid for three consecutive years, from just under 4.8 million viewers for the 2023 debut down to roughly 2.1 million by 2025, even as organizers touted strong local economic impact. Whether a return to a proven 1.5-mile oval can reverse that trajectory, or whether Chicago street racing comes back stronger in 2027, is the subplot running underneath Sunday’s green flag. For now, the more immediate storyline for fans following the latest racing news is a genuine title fight that arrives in Joliet separated by a single point.
