Right now, essentially 0% of brackets are still perfect for this year’s March Madness.

Quick Scoop: What percent of brackets are still perfect?

In recent years, all known public contests (ESPN, Yahoo, NCAA’s own tracker, etc.) have seen every single bracket busted very early in the tournament, often before the end of the first round or shortly after. Upsets happen fast, and once even one favorite falls unexpectedly, millions of brackets lose perfection at the same time.

For 2024, the NCAA’s own tracking showed that the final perfect women’s bracket fell by game 51, and no men’s or women’s brackets survived the full tournament. In typical years with tens of millions of entries across platforms, the count of perfect brackets almost always reaches zero by the end of Day 2, making the effective percentage 0% of active entries.

Why perfection disappears so fast

  • A “perfect bracket” means correctly picking the winner of all 63 NCAA men’s tournament games (or 63 in the women’s main bracket).
  • If every game were a 50–50 coin flip, the odds of perfection are about 1 in 9.2 quintillion.
  • Even when you assume people are reasonably good at picking winners (roughly two‑thirds accuracy), the odds are still around 1 in 120 billion.
  • With millions of unique brackets, that still isn’t enough volume to “expect” a single perfect run in any given year.

Because of those absurd odds, the pool of perfect brackets collapses almost immediately once early upsets hit, and by the time you see this question trending, the real‑world answer is almost always that no perfect brackets remain —hence effectively 0%.

TL;DR: If you’re wondering “what percent of brackets are still perfect” right now, the honest, up‑to‑date, tournament‑wide answer is: basically 0% of all submitted brackets are still perfect.
