Wisconsin vs. Notre Dame odds: Fighting Irish favored as Shamrock Series opens at Lambeau

Notre Dame opens its season against Wisconsin at Lambeau Field in Green Bay on Sunday night, with kickoff set for 7:30 p.m. ET. Kalshi traders have Notre Dame priced at 92% and Wisconsin at 9%, as of this writing. The game is part of Notre Dame's Shamrock Series, its annual neutral-site showcase, though the Fighting Irish are technically the home team.

Notre Dame enters ranked No. 4 after closing the 2025 season with 10 straight double-digit wins, only to watch Miami take the final playoff spot. Wisconsin is coming off a 4-8 season and turns to 34 new transfer additions in a bid to reverse course under fourth-year coach Luke Fickell. The programs have met 17 times, with Notre Dame holding a 9-6-2 edge, and Sunday marks just the third time a major college game has been played at Lambeau Field, following Wisconsin's 2016 upset of No. 5 LSU there.

Snapshot

The market's lopsided read centers on quarterback play. Notre Dame returns CJ Carr, an early Heisman contender who threw for 2,741 yards with 24 touchdowns against six interceptions while going 10-2 as a first-year starter. Wisconsin, by contrast, is breaking in a heavily reshaped roster after a 4-8 finish that ranked among the nation's worst scoring offenses.

Carr said the emphasis entering the opener has been on starting faster than Notre Dame did in 2025, when it opened 0-2 before its 10-game winning streak. Wisconsin's turnaround leans on the transfer class Fickell brought in over the offseason, with the Badgers facing a top-five opponent in their first real test of the new roster.
