Only One Perfect Bracket Remains in 2025 Men's March Madness

After Duke's victory over Baylor, just one of over 34 million brackets submitted has correctly predicted all 42 games so far.

The 2025 NCAA Men's March Madness tournament began with over 34 million brackets submitted across major platforms, but only one remains perfect after Sunday's games.
The last perfect bracket is hosted on ESPN's platform, with all brackets on Yahoo, CBS, USA TODAY, and X already busted.
Major upsets, including McNeese State defeating Clemson and Arkansas beating St. John’s, have rapidly eliminated brackets throughout the tournament.
The odds of creating a perfect bracket are astronomically low, estimated at 1 in 9.22 quintillion when guessing randomly and 1 in 120.2 billion with basketball knowledge.
No one has ever achieved a verifiably perfect bracket in NCAA history, with the closest attempt occurring in 2019 when an Ohio man correctly predicted 49 out of 63 games.
