Notre Dame vs BYU Prediction & Preview: Who Wins Top-10 Matchup In Provo?
Updated October 15, 2026
Updated October 15, 2026
No. 2 Notre Dame brings a 6-0 record to Provo on Saturday, October 17, 2026, but No. 8 BYU has no intention of serving as a footnote to another Fighting Irish victory. The Cougars are 5-0, and this is the first meeting of top-10 teams hosted in Provo. Both teams have College Football Playoff ambitions, and while Notre Dame deserves to enter as the favorite, the gap between winning and winning comfortably is what matters for this matchup in the markets.
Notre Dame A Double-Digit Favorite
As of October 15, Polymarket lists BYU +10.5 at 51¢, implying a 51% chance the Cougars stay within 10 points or win outright. Notre Dame is priced at 79¢ to win the game. Those two positions can both be reasonable. The question here is the final margin, not whether BYU is the stronger team.
Take the Cougars to Cover
My matchup estimate puts BYU's probability of covering +10.5 at 55%, creating a 4% edge at the quoted price. The projected game script favors Notre Dame winning 27-20, with BYU's defense limiting the Irish somewhat and preventing them from pulling away. That edge is modest, particularly with BYU missing a key running back, so I would stop at 53¢ rather than chase a rising contract price.

Why Our Model Sees Value:
“BYU's defensive efficiency, home-field advantage, and ability to extend drives when they have the ball make a double-digit Notre Dame victory less likely than the current price suggests.”
The Irish have climbed to No. 2 after six consecutive victories, including a 58-7 defeat of Stanford last Saturday. BYU is No. 8 and remains unbeaten in Big 12 play at 3-0 following a 24-10 victory over Iowa State. Both teams can strengthen their national standing without changing their conference record in this non-conference contest, while Notre Dame faces its toughest road atmosphere of the season.
ESPN's College GameDay being at this game adds another layer of excitement to what should be an already loud night at LaVell Edwards Stadium. Those making college football predictions on this game will have to determine whether BYU's home-field advantage is enough to offset Notre Dame's edge in talent..
BYU's clearest path to keeping this close runs through Bear Bachmeier. Against Iowa State, the Cougars quarterback passed for 329 yards and 2 touchdowns and rushed for another 109 yards. The Cougars produced 506 yards of offense, although 3 failed fourth-down attempts kept the final score closer than the yardage suggested.
The issue is the absence of LJ Martin, whose ankle injury removes BYU's leading established backfield threat. Notre Dame allows just 214 yards per game and has been particularly difficult to run against. Bachmeier must use his mobility without absorbing too many hits, while receiver Legend Glasker and tight end Walker Lyons give him options on quicker throws.
Notre Dame averages 44 points per game, and quarterback CJ Carr has thrown for 1,378 yards with 16 touchdowns against just 1 interception. Freshman Jonaz Walton supplied a major boost against Stanford with 181 rushing yards, including touchdowns from 97 and 40 yards.
BYU allows only 13.4 points and 254.4 yards per game. Linebacker Cade Uluave and defensive tackle Keanu Tanuvasa anchor a unit capable of disrupting Notre Dame on early downs. Forcing Carr into longer passing situations would be valuable, especially if the Irish cannot reproduce the huge rushing lanes Stanford offered.
Notre Dame cornerback Leonard Moore and defensive tackle Jason Onye entered the week questionable, while BYU linebacker Isaiah Glasker's availability also deserves attention entering this Notre Dame vs BYU matchup. Any absence on defense could alter the game plan against two quarterbacks who can create explosive plays.
BYU converts 54.4% of its third downs, compared with 44.6% for Notre Dame. Extending drives against stronger opposition is a tall order, but it can shorten the game and protect the Cougars' 10.5-point cushion. Notre Dame has the deeper roster and a stronger overall case to win. BYU, however, has enough defensive quality and home-field advantage to keep the score within reach well into the fourth quarter.
