Iowa Speedway to Host Dual NASCAR Events in 2026
The NASCAR Cup Series will reconvene at Iowa Speedway in Newton, Iowa, for the Iowa Corn 350 on Sunday, August 9, 2026, at 3:30 p.m. Eastern. The 350‑lap contest is divided into three stages that conclude on laps 70, 210 and 350, a format that has become familiar to fans of the series.
Last year’s victor, William Byron, will look to defend his title, though he now faces a field of 36 drivers with no open entries. Opening odds released by Caesar’s Sportsbook list Denny Hamlin as the +400 favorite, followed closely by Christopher Bell at +500, setting the stage for a competitive showdown.
