Ohio State opened as a 9.5-point favorite over Notre Dame in the College Football Playoff National Championship Presented by AT&T, per ESPN BET odds.
If that line holds, it would be tied for the second-largest spread in a CFP national championship game and the fourth largest in the CFP/BCS era. Georgia was -13.5 against TCU in the 2022 national championship, while Alabama showed -9.5 against none other than Ohio State to decide the 2020 campaign. Both favorites covered the spread in blowout fashion, combining for a cover margin of 63.
Notre Dame is 12-3 against the spread this season, tied with Arizona State (12-2) and Marshall (12-1) for the most covers in the nation. The Irish are 7-0 ATS against ranked teams and 2-0 ATS as underdogs, with both covers going down as outright victories, including their win over Penn State (-1.5) in the CFP national semifinal.
However, Notre Dame was also on the losing end of the largest outright upset of the college football season when it fell as a 28.5-point favorite to Northern Illinois.
Ohio State is 9-6 against the spread and has been a favorite in every game it has played this season; it has covered the favorite spread in every CFP game thus far, including in its semifinal win against Texas when it covered -6 with overwhelming public support.
The Buckeyes also have been an extremely popular pick in the futures market all season. At BetMGM as of Friday morning, OSU had garnered a leading 28.2% of money and 16.8% of bets to win the national title, checking in as the sportsbook's greatest liability.
Ohio State opened at +700 to win it all this season and is now -350 with just one game to play.
