The College Football Playoff that determines the national champion is expanding from four teams to 12. It will happen no later than the 2026 season. The plan approved by a group of university presidents calls for the six highest-ranked conference champions and six at-large teams to make the playoff. The at-large teams would be chosen by a selection committee. The top four seeds would be conference champions and get first-round byes. A 12-team, 11-game postseason system to crown a champion could be worth as much as $2 billion in media rights to the conferences that play major college football.
