NASCAR Expert Picks for Brickyard 400
Our NASCAR betting experts broke down the Brickyard 400 field and landed on two plays with real value at Indianapolis Motor Speedway. Grab a welcome offer above, then target these picks before the green flag.
William Byron Top 5 Finish (+220): Byron has consistently demonstrated high-end front-running speed at flat, high-speed tracks, recently highlighted by a podium performance at Pocono Raceway, a primary performance proxy for Indianapolis. With Hendrick Motorsports consistently bringing top-tier horsepower to big ovals, Byron's strong track position management makes him a prime candidate to contend for a top-five spot at generous plus-money odds.
Bubba Wallace Top 10 Finish (-155): Wallace proved he can conquer the historic oval by triumphing at the Brickyard last year, showcasing his mastery of managing flat, high-speed corners. Backed by Toyota's blistering 2026 speed across intermediate tracks, Wallace enters with immense confidence and a package capable of comfortably securing another top-10 result.
