how many perfect brackets are left

Right now, there are no publicly verified “perfect brackets” left in the major national trackers for March Madness–style NCAA tournaments this year, and there has never been a fully verified perfect bracket in history.

Quick Scoop: How many perfect brackets are left?

For the 2025 men’s NCAA Tournament (the most recent fully covered season), the pattern was brutal and familiar:

  • After the first full day of games, fewer than 1% of all submitted brackets were still perfect.
  • Very quickly, the number of perfect brackets dropped to single digits across the big platforms.
  • By the end of the early weekend slate, all known perfect brackets were busted , with news outlets reporting zero remaining perfect entries.

Because the odds of perfection are so extreme, once the early upsets hit, the count almost always races down to zero.

Why perfect brackets vanish so fast

Mathematically, the dream is almost impossible:

  • If every game were a simple coin flip, the chance of a perfect bracket would be about 111 in 2632^{63}263, which is roughly 1 in 9.2 quintillion.
  • Even when assuming a reasonably skilled fan who picks games with around 66.7% accuracy , the odds only improve to about 1 in 120 billion for a perfect bracket.
  • Other analyses place the realistic odds at about 1 in 147.5 quintillion , depending on assumptions.

In short: even with tens of millions of brackets filled out, the math still expects zero perfect brackets in most years.

Has anyone ever had a perfect bracket?

Across all the major, verifiable bracket contests:

  • No fully verified perfect men’s NCAA Tournament bracket has ever been recorded.
  • Some years have seen a person stay perfect into the first weekend or early second round, but the streak always ends before all 63 (or 67 including First Four) games are done.

So when people ask “how many perfect brackets are left,” the honest late- tournament answer is almost always: none.

What this means for “how many perfect brackets are left” today

Putting it together:

  • Early in the tournament, you might see headlines like “181 perfect brackets remain out of 34 million” after two days.
  • Within another slate or two of games, especially after big upsets, that count collapses to single digits , then to zero , as reported by national outlets.

Given that trend and the most recent reporting, you can safely assume there are currently zero perfect brackets left in the mainstream contests , even if individual private pools might still have someone briefly close. TL;DR:
The answer to “how many perfect brackets are left?” in any real March Madness window is almost always zero , and that is exactly where things stand now in the tracked public contests.
