College football is in formation once again, as another round of conference realignments go into effect for the 2025 season. With changes every year that bring new rosters, playoff rules and bowl games, the goalposts to keep track of college football always seem to be moving.
Luckily, routine conference realignments have historically brought order to the booming Power Four – the Big Ten Conference, Big 12 Conference, Atlantic Coast Conference (ACC) and Southeastern Conference (SEC) – and beyond. Make it easier to plan your perfect matchup, or bet further with bowl game tickets and College Football Playoffs tickets, by brushing up on the latest college football realignment updates below.
History of Conference Realignments
Conference structures have been fundamental to every major change in college football, from the formation of the NCAA in 1906 to the creation of subdivisions in 1978. The Western Conference, later renamed the Big Ten, became the first of its kind in 1896, followed by current Power Four members the SEC in 1932 and the ACC in 1953. Meanwhile, the Big 12 formed as a result of conference realignments itself in 1996 after the Big Eight Conference, chartered in 1907, combined with the Southwest Conference, which dated back to 1914.
As of 2025, the top-tier Football Bowl Subdivision (FBS) contains 10 conferences: the Power Four, composed of the Big Ten, Big 12, ACC and SEC, plus the the transitional Pac-12 Conference and the Group of Five featuring the American Conference, Conference USA (CUSA), Mid-American Conference (MAC), Mountain West Conference (MW) and Sun Belt Conference (SBC). The Power Four conferences are grouped together for their higher prominence and viewership compared to the Group of Five. This top level of college conferences was previously known as the “Power Five” from 2014 to 2023 before the Pac-12 was relegated to “Group of Five” status following a mass exodus of member universities. In 2025, FBS conference moves were limited to the Group of Five, now Group of Six, with the UMass Minutemen playing in the MAC and the University of Delaware Blue Hens and Missouri State Bears joining Conference USA.
Over the years, college football conference realignments have been used to manage the expanding field of talent and eligible sports programs, while keeping gameplay competitive amongst the various divisions across the country. As the fanbases for each football conference have grown, previously regional conferences such as the ACC have broadened to coast-to-coast opponents or changed the core fabric of their conference entirely, like the Big Ten boasting 18 total members or the Big 12 expanding to 16.
In most modern realignments, schools change conferences due to many different factors, including but not limited to a school’s competitive success, school prestige, scholarship eligibility, geographic footprint, market size/TV viewership, fundraising capabilities, or sponsorship/revenue generation opportunities.
College Football’s Most Recent Conference Realignment
Ahead of the 2025 college football season, several conferences experienced a boost in membership as a result of the condensed Pac-12 Conference. However, more moves across the FCS could have a massive impact on the 2025 bowl games and new 12-team College Football Playoff picture. The current membership of the Power Four and more following the most recent round of college football conference realignments include:
ACC
The ACC stays the same at 17 teams. In 2024, the ACC added its first western U.S. schools with the University of California, Berkeley and Stanford University coming from the Pac-12 and Southern Methodist University (SMU) from the American Conference.

Pac-12
The Pac-12, which was a historic power on the West Coast, shed all but two of its members before 2024: the Oregon State University Beavers and the Washington State University Cougars.
In contrast to the other power conferences, the Pac-12 now has fewer members (2) than the number in their name. Following the 2024 conference realignment, the Pac-12 is more commonly associated with the Group of Five conferences, now Group of Six.
The Pac-12 Conference will continue to operate in its two-school system until its next planned realignment in 2026, when it will add six members:
- Boise State Broncos
- Colorado State Rams
- Fresno State Bulldogs
- San Diego State Aztecs
- Texas State Bobcats
- Utah State Aggies
Group of Six
In the 2024 conference realignment, the American Conference maintained its 14-school membership after recruiting the Army Black Knights to replace the SMU Mustangs. Conference USA raised its total membership to 12 schools after adding the independent Kennesaw State University Owls in 2024, plus the University of Delaware Blue Hens and the Missouri State University Bears in 2025. Meanwhile, the independent UMass Minutemen joined the MAC ahead of the 2025 college football season.
What Future Conference Realignments Are Planned for College Football?
More conference realignments are on the way with several moves already confirmed for the 2026 college football season and beyond. Coming up, the Pac-12 will return with an additional six schools split from the Sun Belt Conference (Texas State Bobcats) and the Mountain West: the Boise State Broncos, the Fresno State Bulldogs, the Colorado State Rams, the San Diego State University Aztecs and the Utah State University Aggies. Meanwhile, the MW will add the University of Hawaiʻi Rainbow Warriors, the University of Texas, El Paso (UTEP) Miners and Northern Illinois University Huskies (for football only) in 2026.
Further ahead, the Louisiana Tech Bulldogs have accepted an invitation to join the SBC no later than July 1, 2027.
