Overview

• 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.
