The NASCAR Cup Series heads to the legendary Indianapolis Motor Speedway this Sunday at 2 p.m. ET for the much-anticipated 2026 Brickyard 400. With only five races left in the regular season, this event also serves as the championship showdown of the NASCAR In-Season Challenge, featuring a thrilling competition between Ryan Blaney and Todd Gilliland for a grand prize of $1 million. Blaney enters as the -320 favorite to outperform Gilliland.

According to FanDuel Sportsbook, the odds for the race highlight Denny Hamlin as the +360 favorite (risking $100 to win $360), while Kyle Larson and Tyler Reddick follow at +650 and +700, respectively. Before placing any bets or finalizing DFS lineups, insights from Mike McClure's proven prediction model are crucial.

McClure, a renowned professional DFS player with over $2 million in winnings, has accurately predicted 30 winners since 2021, including Hamlin's recent consecutive wins at Michigan and Pocono. For the Brickyard 400, however, McClure is skeptical about Hamlin's chances, citing his recent average finish of 9.5 in the last five races and two accidents in his last three outings at this track.

In a surprising twist, the model favors William Byron as a strong contender at +1300, despite his search for a first win this season. With nine top-10 finishes and four top-5 finishes, Byron is positioned well for outright and top-5 bets.

Additionally, McClure is optimistic about a longshot at around +2000, who could potentially surprise the field. For detailed insights and exclusive picks, visit SportsLine to uncover who might take the crown at the 2026 Brickyard 400.
