Iowa Speedway will host a NASCAR Cup Series race for the second time when the 2025 Iowa Corn 350 begins on Sunday afternoon. There are only four races remaining in the regular season, so the pressure continues to mount for the Iowa Corn 350 field. Defending champion Ryan Blaney is one of top betting favorites, according to the latest Iowa Corn 350 odds. Kyle Larson is the +430 favorite, followed by Blaney and William Byron at +500. 

The top four drivers in the Cup Series standings are separated by just 20 points, which is the smallest margin at this stage since 2012. Other contenders for this race include Christopher Bell (+650), Chase Briscoe (+900), Chase Elliott (+900) and Denny Hamlin (+900). Sunday's race is scheduled to start at 3:30 p.m. ET. 

Before making any Iowa Speedway picks, you NEED to see what CBS Sports NASCAR writer Steven Taranto has to say.

Taranto, who moonlights as a sim racer and has 20 career wins in iRacing, is the lead NASCAR writer for CBSSports.com. Taranto was red-hot for SportsLine in 2024 as he nailed 17 winners, including 16-1 longshot William Byron at the Daytona 500 and 14-1 longshot Chase Elliott at Texas. Anybody following his NASCAR picks could have seen HUGE returns!

For the 2025 NASCAR Brickyard 400, Taranto is high on William Byron (+900). He also has a head-to-head prop bet, with Ross Chastain (-140) to finish ahead of Bubba Wallace. "For all we can tell right now, Wallace's win at Indy – and no longer having to deal with the pressure of having to make the playoffs on points or the burden of not having won since 2022 – may very well launch his season to the next level," Taranto said. "But based on last year's Iowa race, any forthcoming breakthrough may not come at Iowa, where Wallace ran 17th while his opponent in this head-to-head matchup, Ross Chastain, finished 11th. I'd take Chastain based on that as well as his Xfinity and Truck resume at Iowa, which included a would-have-been win in 2019 if his truck had managed to pass post-race inspection."

Taranto has also identified four other drivers in his 2025 NASCAR Iowa Corn 350 best bets. He's also high on a huge NASCAR longshot who's around 50-1, potentially netting any backer a HUGE payday! You ABSOLUTELY NEED to see his picks before locking in any NASCAR picks of your own.
