2025 Big Ten Championship odds: Ohio State, Oregon, and Penn State top the board

Ohio State’s quarterback Julian Sayin is expected to lead a strong trio of teams in the Big Ten for the 2025 season. The defending national champion Buckeyes are favored to win the Big Ten Championship at +190, despite losing key players to the NFL draft. Oregon, last year’s conference champion, follows as the second favorite at +260, with their strong roster bolstered by new additions like quarterback Dante Moore. Penn State is close behind in the betting odds at +275, with quarterback Drew Allar being a standout player to watch. Michigan, coming off a positive end to the 2024 season, is listed at +800. Other teams like Nebraska and Illinois could also attract support with odds of 40/1. The 2025 Big Ten Championship is shaping up to be a competitive season among these top teams.
