The 2025 NCAA Men's Basketball Tournament is about to wrap up. Below, we will update you throughout March Madness to see if there are any perfect brackets remaining.

Are there any perfect March Madness brackets left?

Unfortunately, there are zero perfect brackets still out there. In fact, there were none still perfect after the first two rounds of play.

Heading into play on Sunday of the first weekend, there were just three perfect brackets left in ESPN's Tournament Challenge.

At the start of play on Saturday of the first weekend, there were 121 perfect brackets in ESPN's Tournament Challenge. Yahoo Fantasy Sports reported that they had just 11 perfect brackets still standing on Saturday morning.

ESPN had a record 24.4 million completed brackets this year. 

  • 121 perfect brackets remained in ESPN’s Tournament Challenge as of Saturday morning
  • 24,388,569 brackets have fallen

It is estimated that the odds of filling out a perfect bracket are 1 in 9.22 quintillion.

The first two full days of March Madness saw some upsets that had an impact on March Madness odds. None were of the Earth-shattering variety, like a 1 or 2 seed going down, but there were enough to eliminate most people’s brackets from perfection.

No. 12 seed McNeese taking down No. 5 seed Clemson was the biggest upset of the first day. Drake, an 11-seed, beating 6-seeded Missouri also put a dent in many people’s plans for perfection. Colorado State, also a 12 seed, topped No. 5 Memphis on Friday.

Are there any winless March Madness brackets left?

If you’re going to be bad at picking games, you might as well be the worst. One of the more fun props this time of year is attempting to pick as many losers as possible. ESPN reported Friday that there were 30 brackets remaining that picked zero games correctly.

"To 'achieve' a winless bracket, fans only need to get the entire first round wrong," ESPN’s Senior Director of Communications, Kevin Ota, told Covers. "But of course after that, it would be impossible to pick up any wins. In that way, it makes an 'imperfect' bracket easier than a perfect one."
