After hosting the Xfinity Series for the last 15 years, Iowa Speedway hosted the NASCAR Cup Series for the first time last season and it's a stop on the NASCAR schedule yet again with the 2025 Iowa Corn 350 being held on the 0.875-mile oval on Sunday. Ryan Blaney won last year's inaugural Cup run in Iowa and is one of the top favorites, according to the latest 2025 Iowa Corn 350 odds. Blaney and William Byron are +500, trailing only Kyle Larson, who's the +430 betting favorite. Meanwhile, Bubba Wallace likely punched his ticket into the 2025 NASCAR playoffs after a win last week at the Brickyard, and he's a +4000 longshot in the NASCAR at Iowa odds.

The green flag will drop at 3:30 p.m. ET on Sunday, and the race is scheduled for 350 laps around the D-shaped oval. Before making any NASCAR at Iowa predictions, you NEED to see the latest 2025 Iowa Corn 350 picks from SportsLine's proven projection model.
