The Big Ten and SEC sit nearly even in the conference-to-win-national-championship market because both leagues enter 2026 with multiple top-10 caliber programs and proven CFP pathways. The Big Ten carries recent momentum after three straight titles, including Indiana’s undefeated run, while preseason rankings place Ohio State, Oregon, and the Hoosiers among the highest-rated squads. The SEC counters with Georgia’s sustained excellence, Texas’s talent infusion, and additional contenders such as Alabama and Oklahoma that routinely produce deep playoff runs. Depth across both conferences, combined with the 12-team format’s emphasis on conference strength and schedule resilience, keeps implied probabilities tightly bunched rather than allowing one league to pull away.
