The annual NCAA College Basketball Tournament—known as March Madness—is one of the most exciting times of the year for college basketball fans.

What are the March Madness Perfect Bracket Odds?
Filling out a perfect March Madness bracket means correctly predicting the winner of all 63 NCAA basketball tournament games. Having a perfect bracket means that must be 100% correct in all of your picks, including all of the inevitable upsets (when a lower ranked team defeats a higher ranked team) that occur every year.
The mathematical probability of a perfect March Madness bracket are:
1 : 9,200,000,000,000,000,00.
You read that correctly. The chances of correctly predicting a perfect March Madness bracket are astronomically low. In fact, some mathematical models estimate the odds of having a perfect March Madness bracket at one in 9.2 quintillion.
To put it another way, you are more likely to win the lottery multiple times in a row or get struck by lightening twice on the same day than to fill out a perfect bracket.

Is a March Madness perfect bracket even possible?
The short answer is no, it is not possible to fill out a perfect March Madness bracket given the insanely high odds of correctly predicting the winner of all 63 games.
The reason for saying that a March Madness perfect bracket is impossible is simple—there are just too many variables at play in every game that make predicting winners incredibly difficult.
Even the most talented and experienced basketball analysts and sports statistics experts can not predict with complete accuracy how a given tournament game will play out. Factors such as injuries to key players, momentum swings, and elements of chance can all play a role in the outcome of a basketball game. And when you consider that there are 63 games in the tournament, the chances of getting correctly predicting the winner of every single game is virtually zero.
Of course, the fact that a perfect March Madness bracket is essentially impossible should not discourage you from filling out a bracket and attempting to correctly predict the outcome of as many games as possible. Why? Because filling out a bracket and chasing this impossible dream is what makes March Madness such a fun time of year for die-hard and casual basketball fans alike.
Even if you don't have a perfect bracket, you can still compete with your friends and colleagues to see who can get the most games right. And who knows? You might just run into some luck and make some accurate predictions that others did not.

Has There Ever Been a Perfect March Madness Bracket?
Millions of basketball fans have been filling out March Madness brackets since the tournament’s inception in 1939, but has anyone ever had a perfect March Madness bracket?
The answer is no.
Remember that the odds of predicting the winners of all 63 tournament games are astronomically low, with some estimates placing the odds of a perfect bracket at around 1 in 9.2 quintillion.
Even with the rise of advanced analytics and machine learning algorithms, no one person has ever been able to achieve a perfect March Madness bracket, and they likely never will.
How Can You Use Math to Improve Your Bracket Predictions?
Mathematically speaking, filling out a perfect bracket is virtually impossible. But, what are your chances of getting a certain number of games right?
Let’s take a look at some statistics that will shed some light on this question.
According to the NCAA, the chances of correctly predicting the outcome of the first round (the 32 games played during the first two days of the tournament) are about 1 in 4.3 billion. While those odds are not very much in your favor, they are still way better than the odds of predicting a perfect March Madness bracket. In fact, there have been several occasions where someone correctly predicted the winners of all 32 first-round games.

But, as the tournament continues on into the later rounds, the odds of correctly predicting every winner become exponentially smaller. By the time you get to the third round (known as the Sweet 16), the chances of predicting all the games correctly are about 1 in 75.6 million.
As for the point in the tournament when only four teams remain (known as the Final Four), the odds of predicting all games correctly drop to about 1 in 2.4 million.
These odds are only estimates, and the actual chances of getting each game right can vary depending on many factors. The point is that, while the chances of a perfect March Madness bracket are essentially zero, it is still possible to correctly predict winners and have fun competing with others.
In fact, if you were to simply guess the winner of every March Madness game at random, without any knowledge or analysis of college basketball, you would be mathematically expected to correctly predict around half of the total games (about 31.5 out of the 63 games).
So, what should you keep in mind when filling out your March Madness bracket? The best advice we can give is to focus more on making educated based on information such as a teams’ record, matchups, current injuries, and recent performance. You can also take advice from trusted sports analysts and experts that can offer valuable insights that will help you make decisions when filling out your bracket.

Another thing to keep in mind about filling out your bracket is the occurrence of upsets—when a lower ranked team wins against a higher ranked team. Upsets are incredibly common in the NCAA tournament and they are one of the most fun and exciting aspects of March Madness.
With this in mind, don't be afraid to pick a few lower-seeded teams to defeat a higher-seeded opponent, especially during the first two rounds.
On a final note, given that the March Madness perfect bracket odds are impossible, you can let yourself off the hook and simply have fun filling out your bracket, knowing that it will likely get busted during the first round.
The unpredictability of the tournament is what contributes to the 'Madness'—so have fun and good luck!
