Right now, there are zero known “perfect brackets” for any major online NCAA March Madness contest in 2025, and historically no verified bracket has ever gone 63-for-63.

What “perfect brackets” usually means

When people ask “how many perfect brackets” , they almost always mean:

How many fans still have an NCAA March Madness bracket with every game predicted correctly so far?

For the men’s tournament, that means picking all 63 games right; for online contests, the count is tracked across tens of millions of entries.

Latest news (2025 tournaments)

Recent reporting on the 2025 tournaments shows:

  • Major platforms like Yahoo and ESPN saw their last perfect brackets busted within the first few days of the men’s tournament.
  • One ESPN entry was highlighted as the final remaining perfect bracket before it finally missed a pick, meaning 0 out of roughly 24 million were perfect after that loss.
  • The NCAA’s own tracker notes the chance of a fan getting all 63 men’s games right as about 1 in 9.2 quintillion under simple assumptions, which explains why we’ve never seen a verified, end‑to‑end perfect bracket.

So if you’re checking “how many perfect brackets are left?” at almost any point in the tournament, the realistic answer is:

  • Early on: sometimes a handful to a few hundred across all major games.
  • By the end of the first weekend: usually zero.

Why a perfect bracket is so unlikely

A standard men’s NCAA bracket has 63 games , and if each were a 50–50 coin flip, there would be 2632^{63}263 possible ways to fill it out, which is about 9.2 quintillion possible brackets.

Even with basketball knowledge and seeding data, upsets and chaos in March Madness keep eliminating perfect brackets extremely quickly , which is why news sites now run live “perfect bracket trackers” as a kind of running drama every March.

TL;DR:
As of the most recent 2025 tournaments, no perfect brackets remain on the major platforms, and in modern history no one has ever officially finished with a truly perfect 63‑for‑63 men’s bracket.
