The NASCAR Cup Series will continue on Sunday with a first-of-its-kind race on the streets of Chicago. The green flag will drop at 5:05 p.m. ET for the Grant Park 220 and the race is scheduled to go 100 laps around the Chicago Street Course for the first street race in NASCAR's 75-year history. 

Chase Elliott is the 5-1 favorite in the 2023 Grant Park 220 odds from Caesars Sportsbook as arguably the most accomplished road racer in NASCAR today. Tyler Reddick follows him on the NASCAR at Chicago odds board at 13-2 while points leader Martin Truex Jr. is listed at 7-1.

Our proven NASCAR projection model has simulated the race 10,000 times and came up with a surprising leaderboard.

Developed by daily Fantasy pro and SportsLine predictive data engineer Mike McClure, this proprietary NASCAR prediction model takes into account a slew of factors including track history and recent results.

McClure's model is off to a red-hot start this season, already nailing Martin Truex Jr.'s Clash win (20-1), Joey Logano's Duel win (8-1), Kyle Busch's Fontana victory (10-1), Denny Hamlin's triumph in Kansas (6-1) and Kyle Larson's wins at Martinsville (6-1) and the NASCAR All-Star Race (13-2). In Austin, it listed Tyler Reddick as one of its best values and he went on to win for a 10-1 payout. It also impressively nailed five of Kyle Larson's wins during his historic season in 2021. All told, the model has nailed a whopping 12 winners since 2021! Anyone who followed its lead on those NASCAR picks saw HUGE returns.   

Now, the model has dialed in on the NASCAR Chicago Street Race and released its projections.

The Chicago Street Course is a 2.14-mile circuit that cuts through downtown that began as a conceptual track created on iRacing. The track's start/finish line is on South Columbus Drive in front of Buckingham Fountain in Grant Park and will also have sections on famed Chicago streets like Lake Shore Drive and Michigan Ave. It's a 12-turn course with seven of the turns clocking in at 90 degrees and speeds are expected to reach over 100 mph down Lake Shore Drive.

For NASCAR Chicago Street Race, the model is high on William Byron, even though he's a 15-1 longshot in the latest 2023 NASCAR at Chicago odds. He's a target for anyone looking for a HUGE payday. And a massive shocker: Martin Truex Jr., one of the Vegas favorites at 7-1, stumbles big-time and barely cracks the top 10! There are far better values in the 2023 Grant Park 220 starting lineup.

The model is also targeting two other drivers with 2023 NASCAR at Chicago odds longer than 15-1 to make a serious run at the checkered flag! Anyone who backs these drivers could hit it BIG. You ABSOLUTELY need to see who it is before locking in any NASCAR picks.
