Will We Ever See a Perfect March Madness Bracket?

By Luca Leone '27 in Spring 2026

Every year in March, millions of people eagerly fill out a March Madness bracket. Some know nothing about the sport but still participate, while others spend hours analyzing every matchup down to the smallest detail, sometimes creating thousands of brackets to increase their chances of achieving the highly coveted perfect bracket. Despite these efforts, every single bracket eventually gets busted, no matter how hard someone tries. Even with a lifetime supply of optimism, the odds are simply not in your favor.

If you guess randomly, the odds of a perfect bracket are about 1 in 9.22 quintillion. Even with strong basketball knowledge, the odds only improve to about 1 in 120.2 billion, still incredibly unlikely. To put this into perspective, there are an estimated 7.5 quintillion grains of sand on Earth. Randomly guessing one specific grain of sand would actually be 23% easier than picking a perfect bracket. 

The heart of this difficulty lies in upsets, which are also a big reason why people love the tournament. An upset occurs when a lower-seeded team defeats a higher-seeded team. These unexpected wins can destroy a bracket. Lower-seeded teams that make deep runs are often called “Cinderella teams,” and they highlight the unpredictability that defines March Madness.

The closest anyone has come to a perfect bracket was Gregg Nigl, who correctly predicted the first 49 games of the 2019 tournament before his bracket finally broke in the Sweet 16. No one has come closer.

Even though filling out a bracket is essentially a one-way ticket to inevitable disappointment, like watching a 16-seeded Holy Cross beat your predicted champion in the first round, it still creates a strong sense of connection. You don’t have to be a basketball expert to participate, and for many people, it’s simply fun, a tradition, or a friendly competition.

The big question remains: will anyone ever achieve a perfect bracket? Mathematically, it’s almost impossible, but that’s part of the appeal. Every year, people try again, holding onto the same hope, praying that maybe this year will be different.
