Line Movement: Money Coming in on Larson, Blaney, and Preece

Three drivers have seen major shifts in their odds since the market opened, starting with Kyle Larson, whose number has moved from +600 to +450. That steam is fully justified—Larson sits second in the points standings (711), with three wins, 11 top-5s, and 14 top-10 finishes on the year. He’s in top form and clearly has the respect of both bettors and books.

Ryan Blaney has matched that line move, also shifting from +600 to +450. The defending Cup Series champ is seventh in the standings with 10 top-10s and seven top-5s, and is always a threat when the racing tightens up in the summer stretch.

But the surprise mover? Ryan Preece, who went from +10000 to +4000 at BetMGM. With nine top-10s and two top-5s, Preece has quietly put together a strong season—and the market’s clearly taken notice.

Open to Now

• Kyle Larson +600 to +450
• Ryan Blaney +600 to +450
• Ryan Preece +10000 to +4000

Ticket & Handle: Larson, Blaney Drawing Big Money

When it comes to highest ticket percentage, Kyle Larson leads the field with 10.7% of all bets, followed by Ryan Preece (6.5%) and Ryan Blaney (5.9%). No surprise—these are the names showing the biggest line movement and getting the most buzz.

The handle share tells a clearer story about sharp money. Larson leads again with a dominant 22.4% of the total handle, more than Blaney (14.4%) and Christopher Bell (11.3%). Bell, at +475 to win on Sunday, is sitting third in the Cup standings with three wins, 13 top-10s, and eight top-5s. If you’re looking for value behind the favorites, Bell’s a strong pivot.

Highest Handle%

Biggest Liabilities: Books Are Sweating Preece, Larson & Stenhouse

BetMGM’s top liability for this race is Ryan Preece, thanks to the massive movement and public action on his +4000 number, after opening at +10000. If Preece hits, it’s a monster loss for the house. Kyle Larson is the second biggest risk, which says all you need to know about how serious his supporters are. Lastly, Ricky Stenhouse Jr. shows up as a surprise liability as a huge underdog with +15000 but has moved massively after opening at +35000. He’s only put up three top-10s and one top-5 this season across 22 races, but that hasn’t stopped some bold bettors from backing him at long odds.

Biggest Liabilities

• Ryan Preece
• Kyle Larson
• Ricky Stenhouse Jr

NASCAR Iowa Corn 350 Final Lap

Kyle Larson is peaking at the right time, and his dominant metrics plus heavy betting support make him the clear frontrunner. Blaney is lurking, as always, and Ryan Preece is the wild card with liability and value. Keep an eye on Bell as a sneaky mid-tier threat, and don’t be surprised if someone like Stenhouse crashes the party. Whether you’re chasing longshots or betting chalk, the Iowa Corn 350 is shaping up to be one of the most compelling cards of the NASCAR season.
