NASCAR Cup Series fans searching for what channel is the NASCAR race on today are tuning in for the Iowa Corn 350 Powered by Ethanol, set to go green Sunday at 3:30 p.m. ET from Iowa Speedway, according to SportsLine. The race returns after a scheduled week off and is one of just four events left before the postseason, known as "The Chase," begins on September 6.
Ryan Blaney locked up the top starting spot on Saturday with a qualifying lap of 23.474 seconds, SportsLine reported, edging out a strong field that also includes Kyle Larson, Joey Logano and Brad Keselowski rounding out the top four in qualifying. That front-row performance has carried directly into the betting markets, where FanDuel Sportsbook lists Blaney as the outright favorite at plus-240 odds, meaning a $100 wager would return $240 in profit if he wins. Logano and Christopher Bell sit just behind him on the board, both priced at plus-650.
While the exact broadcast channel for Sunday's race was not specified in the available reporting, NASCAR Cup Series events are typically simulcast across national cable and streaming partners as part of the sport's season-long media rights agreements, and fans checking listings for today's Iowa race should expect coverage timed to the 3:30 p.m. ET start. Local listings and NASCAR's official schedule remain the most reliable way to confirm the specific network carrying any given week's race, since assignments can rotate through the year.
A Model Built on Simulated Laps
Beyond the raw odds, plenty of bettors and fans are leaning on data-driven predictions to shape their Sunday afternoon. Longtime DFS specialist Mike McClure, who SportsLine describes as having more than $2 million in career daily fantasy winnings, has run his NASCAR simulation model 10,000 times specifically for the Iowa Corn 350. The model doesn't just spit out a favorite; it simulates every lap of the race, weighing matchups and statistical trends to build a projected leaderboard.
According to SportsLine, McClure's model has correctly called 31 race winners since 2021, including 13 since the start of the 2025 season. Among the model's recent hits were Denny Hamlin's back-to-back victories at Michigan and Pocono, results SportsLine says would have produced significant returns for anyone who followed the model's lead at the time.
Fading the Defending Champion
One of the more striking calls from the model involves William Byron, who won last year's race at Iowa Speedway and returns this weekend priced at plus-1100 to repeat. Rather than backing the defending winner, McClure's simulations suggest Byron will struggle to crack the top 10 in Sunday's field, a notable fade given his history at the track.
Instead, the model is bullish on Kyle Larson, who qualified in the top four and enters the race at plus-850 on the FanDuel board. SportsLine reports the model views Larson as a legitimate top-two contender for the win, a more optimistic read than the market price suggests. Larson's qualifying speed, paired with the model's lap-by-lap simulation approach, appears to be driving that confidence.
SportsLine also indicated the model has flagged a longshot priced above plus-1500 as a potential factor in Sunday's outcome, though the specific driver behind that pick was not detailed in the available reporting. Longshot value plays are a recurring feature of McClure's weekly breakdowns, aimed at bettors looking for higher-payout alternatives to the favorites at the top of the board.
Why Iowa Matters in the Regular-Season Push
The timing of the Iowa Corn 350 adds extra weight to Sunday's results. With the regular season winding down and the Chase field set to be finalized after four more races, drivers on the postseason bubble have limited opportunities left to lock in points positions or grab a win that could bolster their playoff seeding. Blaney's pole-winning lap and the tight cluster of qualifiers behind him, Larson, Logano and Keselowski, signal a competitive field heading into the closing stretch of the regular season.
For bettors weighing Sunday's card, the gap between market pricing and model projections is where much of the intrigue lies. Blaney's plus-240 favorite status reflects his qualifying speed and general form, but the model's specific enthusiasm for Larson at plus-850, combined with its skepticism toward Byron at plus-1100, illustrates how simulation-based approaches can diverge sharply from straightforward oddsmaking.
As for logistics, fans still hunting down exactly what channel the NASCAR race is on today should rely on their regional listings or NASCAR's published broadcast schedule closer to the 3:30 p.m. ET green flag, since coverage details for Cup Series events are set on a race-by-race basis throughout the season. What is confirmed, according to SportsLine's reporting, is the start time, the pole position winner, the odds board, and the contrarian picks now circulating ahead of Sunday's green flag at Iowa Speedway.
