It's still early, but most people already have plenty of blemishes on their March Madness brackets. That said, there are also thousands of perfect brackets still out there. 

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?

We’re only one full day into the 2025 NCAA Men’s Basketball Tournament, but yes - there are still thousands of perfect brackets remaining.

ESPN’s Tournament Challenge had a record 24.4 million completed brackets this year. Of those 24.4 million, 25,802 brackets are still perfect. That number could very well dwindle to zero by the end of Round 1 Friday night.

  • 25,802 perfect brackets remain in ESPN’s Tournament Challenge as of Friday morning
  • 24,362,742 brackets have fallen

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

The first full day 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 day. Drake, an 11-seed, beating 6-seeded Missouri also put a dent in many people’s plans for perfection.

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 reports that there are 30 brackets remaining that have 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."
