"Sixteen of the league’s schools are fully vested members and received full shares, but their total amounts varied by CFP participation. Ohio State secured $91.55 million, Penn State earned $88.9 million, and Indiana collected $81 million, while 13 other members collected between $76 million and $79 million. Oregon and Washington receive only partial shares until 2030 and earned $48 million and $46 million, respectively. Oregon competed in the 2024-25 CFP, which explains the $2 million difference."
