Key Predictions for the 2026 Iowa Corn 350

• McClure is fading William Byron at +900, despite his previous success at Iowa. Byron has struggled in 2026, finishing 12th or worse in five of his last six races.

• Conversely, Kyle Larson at +900 is viewed as a top-two contender. Despite recent accidents, Larson has shown strong performance on short tracks, previously leading 80 laps at Iowa in 2024.

McClure also highlights a longshot at nearly +2000 who could surprise the field, potentially offering a significant return for bettors.
