How Many Perfect Brackets Are Left? As of the Elite Eight of the 2025 NCAA Tournament, the quest for a flawless bracket in both the men’s and women’s tournaments is over, but HOW.EDU.VN is here to break down the statistics, explore the odds, and offer insights into why achieving bracket perfection is such a monumental challenge. Dive into bracketology, tournament predictions, and sports analytics to understand the intricacies of March Madness.
1. How Many Perfect Women’s March Madness Brackets Are Left?
No perfect women’s March Madness brackets remain as of the Elite Eight in 2025. According to the NCAA, the last remaining perfect bracket was eliminated during the second game of the regional finals when No. 1 UCLA Bruins defeated No. 3 LSU Tigers. This bracket had correctly predicted the Final Four teams as No. 1 South Carolina, No. 1 Texas, No. 2 UConn, and LSU, with South Carolina winning the national championship.
1.1 Initial Submissions and Early Eliminations
Approximately 5 million women’s bracket submissions were made across major online platforms such as NCAA Women’s Bracket Challenge Game, ESPN, CBS, Yahoo, and USA TODAY. After the opening day of the tournament, only about 83,000 brackets remained intact, and roughly 2,500 survived the first round, according to the NCAA.
1.2 Progression to Sweet 16 and Beyond
Entering the second day of Round 2 action, 141 perfect brackets were still in contention. Of these, 33 correctly predicted the Sweet 16 teams. By the end of the first day of the Sweet 16, only nine perfect brackets remained, but eight were eliminated when No. 2 TCU defeated No. 3 Notre Dame.
1.3 Comparison to Previous Years
In comparison to the previous year, only four brackets remained perfect after the second round, highlighting the unpredictable nature of the tournament and the difficulty of maintaining a perfect bracket.
2. How Many Perfect Men’s March Madness Brackets Are Left?
No perfect men’s March Madness brackets remained by the end of the second round in 2025. The final perfect bracket was busted in the 43rd game when No. 3 Kentucky defeated No. 6 Illinois, according to the NCAA.
2.1 A Unique Start to the Tournament
The 2025 tournament was the first since 2019 where all men’s brackets weren’t busted in the first round. Entering the second round, there were 181 perfect brackets still in play.
2.2 Factors Contributing to Bracket Busting
Several factors contribute to the rapid elimination of perfect brackets in the men’s tournament:
- Upsets: Unexpected wins by lower-seeded teams are a common occurrence, disrupting even the most carefully constructed brackets.
- Parity: The increasing competitiveness among teams makes it harder to predict outcomes accurately.
- Injuries: Key player injuries can significantly impact a team’s performance, leading to unforeseen losses.
3. What Are the Odds of Creating a Perfect Bracket?
The odds of creating a perfect March Madness bracket are astronomically low. The exact odds depend on whether you’re making random guesses or using knowledge of basketball:
3.1 Random Guessing
If you were to fill out a bracket by randomly guessing, the odds of getting every game correct are:
- 1 in 9.2 quintillion for the women’s tournament (263).
- 1 in 9.2 quintillion for the men’s tournament (263).
These odds are so high because each game is essentially a coin flip, and you need to correctly predict the outcome of 63 games.
3.2 Informed Guessing
If you have some knowledge of basketball and make informed predictions, the odds improve slightly but are still incredibly challenging:
- 1 in 120.2 billion is a commonly cited estimate.
- Some experts believe that a knowledgeable basketball fan might improve the odds to 1 in 1 billion.
3.3 Factors Influencing the Odds
Several factors can influence the odds of creating a perfect bracket:
- Knowledge of the Teams: Understanding team strengths, weaknesses, and player statistics can improve your predictions.
- Historical Data: Analyzing past tournament results and trends can provide insights into potential outcomes.
- Luck: Even with extensive knowledge, luck plays a significant role due to the unpredictable nature of the tournament.
4. Why Is It So Difficult to Achieve Bracket Perfection?
Achieving a perfect bracket is incredibly difficult due to the inherent unpredictability of March Madness. Several factors contribute to this challenge:
4.1 Upsets and Underdog Victories
Upsets are a defining characteristic of March Madness. Lower-seeded teams often defeat higher-seeded teams, disrupting even the most meticulously crafted brackets. These unexpected results are difficult to predict because they often hinge on factors such as:
- Momentum: A team gaining confidence and playing above expectations.
- Matchup Advantages: A lower-seeded team exploiting specific weaknesses in a higher-seeded team.
- Individual Performances: A player having a standout game that propels their team to victory.
4.2 The Parity in College Basketball
The increasing parity in college basketball means that the gap between top-ranked teams and lower-ranked teams is narrowing. This parity makes it more difficult to predict outcomes accurately because many games are closely contested and can go either way. Factors contributing to this parity include:
- Improved Coaching: Better coaching strategies and player development across more teams.
- Increased Player Transfers: Players transferring between schools can quickly change the competitive landscape.
- Resource Allocation: More schools investing in their basketball programs, leading to better facilities and training.
4.3 The Element of Chance
Even with extensive knowledge and careful analysis, luck plays a significant role in March Madness. A bad call by a referee, an unexpected injury, or a player having an off night can all impact the outcome of a game. These unpredictable elements make it nearly impossible to create a perfect bracket.
4.4 Psychological Factors
The pressure of the tournament can affect players and teams, leading to unexpected performances. Teams that perform well during the regular season may falter under the spotlight of March Madness, while other teams may rise to the occasion and exceed expectations.
5. Strategies for Improving Your Bracket Predictions
While creating a perfect bracket is highly unlikely, there are strategies you can use to improve your predictions and increase your chances of winning bracket pools:
5.1 Researching Teams and Players
Thoroughly research the teams and players participating in the tournament. Look at factors such as:
- Team Statistics: Analyze offensive and defensive efficiency, scoring averages, and rebounding rates.
- Player Performance: Evaluate individual player statistics, including points per game, assists, and turnovers.
- Strength of Schedule: Consider the quality of opponents a team has faced during the regular season.
5.2 Analyzing Matchups
Pay close attention to the specific matchups in the tournament. Consider factors such as:
- Style of Play: How do the teams’ offensive and defensive styles match up against each other?
- Key Matchups: Which players will be guarding each other, and who has the advantage?
- Coaching Strategies: How do the coaches approach tournament games, and what adjustments might they make?
5.3 Considering Historical Data
Analyze past tournament results and trends to identify potential patterns. For example:
- Seed Performance: How often do higher-seeded teams win against lower-seeded teams?

Injuries to key players can be particularly devastating, as they can affect a team’s scoring ability, defensive strength, and overall chemistry.
- Scoring Impact: If a team’s leading scorer is injured, it can struggle to generate points.
- Defensive Weakness: If a key defender is injured, it can become more vulnerable to opposing offenses.
- Team Morale: Injuries can also affect team morale, leading to decreased confidence and motivation.
7.2 Team Adjustments and Adaptations
Teams must make adjustments and adaptations when key players are injured. This might include:
- Shifting Roles: Other players may need to step up and take on larger roles.
- Changing Strategies: Coaches may need to alter their offensive and defensive strategies.
- Relying on Depth: Teams may need to rely on their bench players to fill the void.
7.3 Psychological Effects of Injuries
Injuries can also have psychological effects on teams. Players may feel added pressure to perform well in the absence of their injured teammates, and the team as a whole may experience a loss of confidence.
7.4 Identifying Potential Upsets
Injuries can create opportunities for upsets, as teams that are missing key players may be more vulnerable to lower-seeded opponents. It’s important to stay informed about injury reports and consider how injuries might affect a team’s performance when making bracket predictions.

8.1 Conference Strength
The strength of a conference can be a good indicator of how well its teams will perform in the tournament. Conferences with multiple highly ranked teams are generally considered stronger, as their teams have been tested against tough competition throughout the regular season.
8.2 Historical Performance
Looking at the historical performance of different conferences in March Madness can reveal trends and patterns. Some conferences consistently outperform expectations, while others tend to underperform.
