The Pac-12, ACC and Big Ten are having "high-level discussions" about forming an alliance between the three conferences, per Max Olson of The Athletic:

"Talks have centered around not just a scheduling alliance in football but in broader cooperation, according to sources in the three conferences. Pac-12 commissioner George Kliavkoff, Big Ten commissioner Kevin Warren and ACC commissioner Jim Phillips have been having conversations for several weeks."

As The Athletic noted, it's unclear how scheduling would work between the three conferences, but the goal is to get on the same page and vote on key concerns, including College Football Playoff expansion and any "NCAA governance changes," per Olson.
