The NASCAR O'Reilly Series is set to make its highly anticipated debut at Chicagoland Speedway this July, headlining the Cuervo 300, a 300‑mile event that marks the series' first appearance on a 1.5‑mile oval since the May 2026 race at Charlotte Motor Speedway.
A Milestone Return to a 1.5‑Mile Venue
The track, last seen in NASCAR competition in 2019 before the pandemic halted live events, will now host a 1.5‑mile layout that previously saw Cole Custer claim victory in 2019, with Jesse Love finishing second in the May 2026 Charlotte race that served as a precursor to the upcoming Chicagoland showdown.
Historical winners of the series include Ross Chastain and Cole Custer, both of whom have left a mark on similar circuits. Their past performances add a layer of intrigue to the upcoming race, as fans anticipate whether the same drivers can replicate their success on the Illinois venue.
Betting Favorites and Dark Horses
Bookmakers have already opened markets on the contest, listing Justin Allgaier at +300 and Connor Zilisch at +400 as the early favorites, while Brent Crews and Chase Elliott sit at +450. A cluster of drivers including Brandon Jones, Corey Day and Jesse Love hover around +1200 to +1400, and Sheldon Creed and Sam Mayer are also in the mix at +1800.
The field also features veterans such as Joey Logano, Michael Annett, Ross Chastain, Cole Custer and others who have tasted success on comparable tracks in the past. Their presence ensures a deep and competitive lineup for the Cuervo 300.
What the Odds Mean for the Series
The odds reflect both the drivers' recent form and the unique challenges of a 1.5‑mile oval. While Allgaier and Zilisch lead the market, the spread among the mid‑tier drivers suggests a tightly contested race where strategy and experience could play decisive roles.
As the event approaches, teams are fine‑tuning their setups and drivers are preparing mentally for the demands of the Chicagoland layout. The Cuervo 300 promises to be a pivotal moment for the O'Reilly Series, blending historic significance with fresh betting excitement.
