The NASCAR Cup Series continues Sunday at 3:30 p.m. ET with a stop at Iowa Speedway for the 2026 Iowa Corn 350 Powered by Ethanol. It’s one of just four races remaining in the regular season, as “The Chase” is set to begin on Sept. 6. These races are especially important for drivers around the postseason cut line such as Austin Cindric, Ryan Preece and Erik Jones. The 2026 Iowa Corn 350 odds via FanDuel Sportsbook list points leader Denny Hamlin as the +470 favorite (risk $100 to win $470) to win this race, with Ryan Blaney at +500 and Christopher Bell at +550. William Byron won this race last year, and he’s +900 in the newest NASCAR at Iowa odds.

2026 NASCAR at Iowa predictions
For NASCAR at Iowa 2026, McClure is fading Byron, the defending champion of this race, at +900. Byron has a win and a runner-up in two events at Iowa, so it’s easy to see why he’s getting lower odds this week. However, is still winless in 2026, and hasn’t finished higher than third in any event. He’s been especially cold recently, finishing 12th or worse in five of his past six races, so the model doesn’t like him as a top contender for Sunday, saying he barely finishes in the top 10.
Another surprise: The model is high on Kyle Larson at +900, calling him a top-2 contender. Accidents have slowed Larson recently, but he’s not far removed from a stretch of four straight top-5 finishes this year. Larson is historically strong on short tracks, and he led 80 laps at this race in 2024 before an accident. See which other drivers the model is backing at SportsLine.
