The Power 4 – the SEC, Big Ten, ACC and Big 12 – are college football’s wealthy upper tier, while the Group of 5 (now effectively a Group of Six with the reborn Pac-12) comprises the American, Conference USA, MAC, Mountain West, Sun Belt and Pac-12.
The divide is informal but governs everything: money, scheduling, playoff access and recruiting. Here’s the full map.
COLLEGE FOOTBALL EXPLAINED
Power 4 vs. Group of 6
One sport, two economies
THE POWER 4
SEC, B1G, ACC, B12
Each champion gets an automatic CFP bid
THE GROUP OF 6
AAC, CUSA, MAC, MW, SBC, Pac-12
One CFP spot: the highest-ranked G6 team
THE MONEY GAP
Massive
Power-league media deals dwarf G6 payouts many times over
IT’S INFORMAL
No official tier
All are FBS – the divide is money and access, not rulebook
The two tiers, mapped
Who’s where and what it means
| Element |
Detail |
| The Power 4 |
SEC (16), Big Ten (18), ACC (17 football members) and Big 12 (16) – the leagues holding the sport’s biggest media contracts and every recent national champion |
| How P5 became P4 |
The 2024 Pac-12 collapse – USC, UCLA, Oregon and Washington to the Big Ten; others to the Big 12 and ACC – deleted a power league in one realignment cycle |
| The reborn Pac-12 |
Rebuilt for 2026 with Oregon State, Washington State and six additions (Boise State, Colorado State, Fresno State, San Diego State, Utah State, Texas State) – competing in the Group of Six tier |
| CFP access, 2026 rules |
Power 4 champions get automatic bids regardless of ranking; the Group of Six gets exactly one spot – its highest-ranked team, champion or not |
| The scheduling relationship |
G6 programs fill power-league schedules as paid road opponents – the buy-game economy is the tiers’ most regular interaction |
| The talent pipeline |
The portal era turned G6 rosters into proving grounds – break out on a Tuesday MACtion broadcast, transfer up by January |
Life in each tier
What the divide feels like on the ground
| Dimension |
The gap |
| Media money |
Power schools reportedly receive tens of millions annually from conference distributions; G6 schools receive single-digit millions – the gap funds everything else |
| Revenue sharing |
The House settlement’s player-pay cap is easier to fund at power scale – many G6 programs share far below the cap |
| Facilities and staff |
Power programs field NFL-sized support staffs and palaces; G6 programs compete on development and scheme |
| The dream scenario |
A G6 playoff run remains the sport’s best underdog story – the automatic spot guarantees the tier a seat at the table every December |
TIER FACTS
The names are unofficial
No NCAA document defines Power 4 or Group of 5 – the labels are media shorthand that hardened into structure.
Notre Dame fits neither
The sport’s most famous independent sits outside both tiers – with power-level money and its own CFP access rule.
The ‘Power 2’ is next
SEC and Big Ten revenues now dwarf even the ACC and Big 12 – insiders increasingly describe a tier above the tier.
A Divide With No Rulebook
The Power 4/Group of 6 split is entirely informal – every member is an FBS program playing the same sport under the same rules – yet it determines media revenue, playoff math, scheduling roles and roster economics more than any official classification. The 2026 CFP structure made the divide explicit: four automatic bids for power champions, one spot for the entire G6 tier, as covered in how the College Football Playoff works. Conference membership itself is tracked by the NCAA.
The Bottom Line
Four power leagues with automatic playoff bids and giant media deals; six others sharing one playoff spot and a fraction of the money – college football’s two tiers are unofficial, unequal and, thanks to the portal and the buy-game economy, permanently intertwined.
