ACC college football power rankings get major shakeup after Week 4 – Week 4 of the 2026 college football season delivered exactly the kind of chaos that makes the ACC so difficult to figure out. Several teams that entered the weekend with momentum saw their stock fall, while others used impressive victories to push themselves into the conversation near the top of the conference.
Miami remained the team to beat after another dominant performance, but the biggest story was what happened immediately behind the Hurricanes. Louisville suffered a costly home loss to Wake Forest, while Duke and Wake Forest continued to exceed expectations. Clemson also made a move after winning on the road at California, and Pittsburgh strengthened its case with a shutout.
The result was a dramatically different ACC picture heading into Week 5. One Week 4 power-ranking analysis placed Miami first, Pittsburgh second and Wake Forest third, with Clemson moving into eighth and Stanford making one of the biggest jumps of the week.
Miami Remains at the Top
Miami did not leave much room for debate in Week 4. The Hurricanes overwhelmed Central Michigan 52-3, continuing a strong start that has kept them near the top of both conference discussions and the national rankings. The performance was particularly convincing because Miami controlled the game from beginning to end rather than relying on a late escape.
Quarterback Darian Mensah was nearly perfect through the air, while Miami’s defense once again showed why it entered the season with considerable expectations. The Hurricanes had already been one of the ACC’s strongest defensive teams through the first few weeks, and their ability to limit Central Michigan kept the game from becoming competitive.
The bigger question now comes this weekend. Miami’s first major test of the new week is a road matchup against Clemson. That game should provide a much better indication of how the Hurricanes compare with the conference’s other serious contenders because Clemson has shown signs of improvement after a difficult opening stretch. For now, Miami’s position has remained stable while the teams around it have moved considerably. That stability is important in a conference where the middle of the rankings has become increasingly difficult to separate.
Louisville Takes the Biggest Hit
Louisville entered Week 4 with plenty of momentum after moving up in the ACC picture. Instead, the Cardinals suffered one of the weekend’s most damaging results, falling 30-27 at home to Wake Forest. The loss immediately changed the conversation around Louisville and created space for other teams to move upward.
The game came down to the final moments, making the defeat even more frustrating for the Cardinals. Wake Forest blocked a potential game-tying field goal in the closing seconds to preserve the three-point victory. It was the kind of result that can completely reshape a conference race because Louisville had previously looked like one of the teams positioned closest to Miami.

Louisville’s setback also demonstrates why early-season power rankings can change so quickly. A team can look like a championship contender one weekend and then face an entirely different evaluation after a single conference loss. Louisville still has time to recover, but the Cardinals no longer have the same margin for error.
Meanwhile, Wake Forest deserves significant credit for taking advantage of the opportunity. The Demon Deacons entered the game looking for another statement result after playing Miami competitively earlier in the season. The win over Louisville provided exactly that.
Wake Forest and Pittsburgh Make Their Move
Wake Forest was one of the biggest beneficiaries of Week 4. The Demon Deacons climbed sharply in several ACC power rankings after their 30-27 road win over Louisville. One Week 4 ranking moved Wake Forest all the way to No. 3, behind Miami and Pittsburgh.
The victory was not simply about surviving a close game. Wake Forest demonstrated that it could handle Louisville’s physical running attack while generating enough offense to win on the road. That combination is important as the conference schedule becomes more demanding.
Pittsburgh also made a strong move. The Panthers dominated Bucknell 59-0, with quarterback Mason Heintschel throwing six touchdown passes. Although a game against an FCS opponent does not provide the same information as a conference matchup, Pittsburgh handled the assignment in emphatic fashion.
That performance helped Pittsburgh rise to No. 2 in one current ACC power ranking. The Panthers had already shown offensive firepower earlier in the season, and their defensive performance against Bucknell added another positive element. The next challenge will be proving that the same level of execution can carry over against stronger ACC competition.
Clemson Quietly Starts Moving Up
Clemson’s season has not followed the smooth path many expected, but the Tigers gave themselves another reason for optimism in Week 4. Clemson traveled to California and came away with a 24-10 victory. The defense played a major role, limiting the Golden Bears and helping the Tigers control the game on the road.
The victory was enough for Clemson to rise in several power-ranking assessments. One ranking placed the Tigers eighth after the win, noting the defensive resilience despite continued questions about the offense. Clemson now faces Miami, making the timing of its improvement particularly important. The Tigers have an opportunity to move much higher in the ACC conversation if they can turn their defensive strength into a complete performance against the conference’s current No. 1 team.
At the same time, the Miami matchup provides a reality check. Clemson’s victory over California was valuable, but Miami represents a substantially different challenge. The result could have a major effect on the next round of ACC power rankings.
Stanford Becomes One of the Week’s Biggest Movers
Perhaps the most unexpected movement came from Stanford. The Cardinal defeated Georgia Tech 34-27 after overcoming a halftime deficit, producing one of the conference’s more surprising results of the weekend. Quarterback Davis Warren was central to Stanford’s comeback, throwing for 396 yards. The Cardinal’s ability to reverse the momentum after trailing 20-10 at halftime gave them a major boost in the conference hierarchy. One Week 4 ranking moved Stanford to No. 13, a significant jump from where the team had been previously positioned.
Georgia Tech, meanwhile, went in the opposite direction. The Yellow Jackets appeared to have control of the game after building their halftime advantage, but the second half completely changed the outcome. Stanford outscored Georgia Tech 24-7 after halftime. That collapse has put Georgia Tech under considerably more pressure. A team that entered the season with positive expectations now sits at 1-3, according to a Week 5 ACC ranking published after the Stanford loss.

Duke, Virginia and Florida State Add More Competition
The reshuffling does not stop with the teams at the top. Duke continued its undefeated start by crushing William & Mary 62-7, while Virginia defeated Delaware 42-3. Florida State also handled Central Arkansas 34-7. Those results came against teams outside the ACC, so they do not carry the same weight as Wake Forest’s win over Louisville or Clemson’s victory over California. Still, dominant performances matter when teams are being separated in weekly power rankings. ACC college football power rankings get major shakeup after Week 4
Duke has been particularly interesting because the Blue Devils were not widely viewed as one of the conference’s leading teams entering the season. Their unbeaten start has changed that conversation. A recent ACC ranking noted that Duke and Wake Forest have both exceeded preseason expectations while Louisville and SMU have shown more questions than initially expected.
SMU did win in Week 4, defeating Missouri State 34-24, but the Mustangs did not dominate the way their ranking suggested they might. Missouri State scored 14 fourth-quarter points before SMU closed out the victory. That result leaves SMU in an interesting position. The Mustangs remain relevant, but they now have more to prove as conference play intensifies.
Week 5 Could Shake Everything Up Again
The biggest lesson from Week 4 is that the ACC remains unsettled. Miami has maintained its position at the top, but the teams immediately behind the Hurricanes are changing rapidly. Pittsburgh has surged after another convincing victory. Wake Forest has transformed itself from an intriguing team into a legitimate factor with a road win over Louisville. Clemson is beginning to recover momentum, while Duke continues to build an undefeated résumé. Stanford’s comeback against Georgia Tech has also added another unexpected team to the middle of the conference picture.
The upcoming Miami-Clemson matchup could be particularly important. Miami has not yet faced the kind of ACC opponent that can seriously challenge its position, while Clemson has an opportunity to demonstrate how much it has improved.
The conference’s early-season power rankings therefore remain fluid. Week 4 did not establish a definitive order so much as create another set of questions. Miami is still sitting at the top, but the race behind the Hurricanes has become much more crowded. And with conference games carrying greater weight from this point forward, another weekend of results could make the current rankings look just as different as they did one week ago.
