The 49ers suffered a 29-20 road loss to the Falcons, dropping from 6-0 to 6-1 after an impressive start to the season. That left just two undefeated teams: one in the AFC and one in the NFC.

While it may only be a matter of time until the NFL's only wire-to-wire undefeated team knows its place in history is safe once again, the buzz will continue into November.

Here's a look at which teams are still undefeated.

Which NFL teams are still undefeated?

Chiefs (5-0)

The Chiefs, who were the NFL's last remaining unbeaten team in 2024, are once again looking strong to start the season. Kansas City has wins over the Broncos, Colts, Dolphins, Raiders and Chargers through six weeks, with a bye also included. The schedule, however, is about to get much tougher.

There is a lull after road matchups with the Seahawks and Broncos, but the Chiefs will face the Bills, Rams, Bengals, Patriots and 49ers in consecutive weeks starting on Thanksgiving. Patrick Mahomes and co. are undoubtedly well-prepared to face tougher competition, but winning each and every game might be too tall of a task.

Vikings (6-0)

Do you believe in the Vikings yet? Some don't because Minnesota's offense has been inconsistent, but the defense is playing like the best in the NFL.

The Vikings are allowing an average of just 10.4 points per game since allowing 22 in their season opener, and they shut out the Colts in the second half on Sunday to keep their perfect record intact. Fittingly, Minnesota ended the game by intercepting Daniel Jones.

The Vikings have wins over the Packers, Bears, Buccaneers, Dolphins, Saints and Colts, but their schedule is also about to get much more difficult. Minnesota goes to Detroit, Green Bay and San Francisco in the next four weeks, with a matchup against the Bills also in that stretch.

Last team to enter November undefeated

No team started better than 4-0 last season, so no one entered November unbeaten. The most recent team before 2026 was the Chiefs in 2024, when they started 9-0 before a mid-November loss to the Bills.

By beating the Colts on Sunday, the Vikings guaranteed they will go into their next game on Nov. 1 with a perfect record.
