The Iowa Corn 350 is set for Sunday, Aug. 9, at Iowa Speedway, and defending NASCAR Cup Series regular season champ William Byron is aiming to repeat as Iowa Corn 350 champion this weekend. While many of NASCAR's races are long-standing and historic, the Iowa Corn 350 is a newer addition to the schedule, with the 2026 installment just the third in this race's history. Byron won it last year, while Ryan Blaney was victorious in the debut of this race back in 2024.
Byron is +900 to repeat, according to the latest Iowa Corn 350 odds at DraftKings Sportsbook, while Blaney is +550. Denny Hamlin, who has won five times this season, is the +400 favorite, followed by Christopher Bell at +500 on the NASCAR odds board.
The race is set to begin at 3:30 p.m. ET on Sunday. If you want to wager on NASCAR this weekend, here's how to bet on the Iowa Corn 350 as well as where to bet on the 2026 Iowa Corn 350. And for more NASCAR betting tips, check out our NASCAR betting guide.

Hamlin enters as the favorite after picking up five wins on the year and nearly coming away with a win two weeks ago at the Brickyard 400, which Corey Heim took. Hamlin, who sits atop the NASCAR Cup Series standings, is a top candidate to emerge victorious in every race he partakes in, though it's worth noting he finished 24th each of the last two years at the Iowa Corn 350.
The only two winners this race have ever seen are Blaney and Byron. Both are in the top five in terms of odds, with Blaney having the third-best odds to win and Byron being tied for fifth with Logano.
Another name to keep an eye on is Reddick, who sits second behind Hamlin in the standings. He has also won five times this year, but he's been kept out of the winner's circle since April 19. Reddick does have three top-10 finishes over his last seven races, though he's finished 30th or worse three times over that stretch as well.
How to bet on the 2026 Iowa Corn 350
Betting on the Iowa Corn 350 is a bit different than wagering on other NASCAR events. The recent Brickyard 400, for instance, has a lengthy history with 30 installments, and this year's race had plenty of past winners. But the Iowa Corn 350 is back for just its third race, so Blaney and Byron are the only two winners this race has ever known.
That, of course, makes both drivers very appealing options this week. Both are among the favorites, but there's more value on these two than there is with Hamlin, who's the clear betting favorite at all the top sportsbooks. Last year, Blaney finished fifth after winning in 2024, when Byron finished second. Both have had lots of success even in the year they didn't win, which is well worth noting.

Hamlin doesn't have the best betting value on his side, but he is the best racer in the field this year. He has struggled in this race with two 24th-place finishes, but he's coming off a fifth-place finish, has won five times on the year and leads the standings. He's a strong contender this week, as the odds boards show.
Another driver to keep a close eye on is the youngster Hocevar. He's +2500 to win, so while he's not a true longshot, there's a ton of value on him here. Hocevar is arguably the sport's fastest-growing star, and he finished in the top 10 in the previous two Iowa Corn 350s. He's also finished in the top 10 in two of his three prior races entering the weekend, so he's in good form right now.
