The Ultimate Data Bracket

This is Dimers’ most accurate bracket, built with advanced simulations that analyze every matchup to maximize your chances of winning your pool in 2025. By balancing favorites and key upsets, this bracket is designed to give you the best shot at success, whether you’re playing in a casual pool or a high-stakes contest.

It happens every year. A 14-seed represented by a school you’ve hardly ever heard of—are they even accredited?—shows up when it matters most and knocks off the 3-seed you had making it to the Elite Eight in the first round of the tournament. We know it’s likely going to occur at least once this tournament. So how does Dimers prepare?

Our most accurate bracket is built with advanced simulations that analyze every matchup, while also factoring in historical tournament trends in order to identify the inevitable key upsets. 

While a “chalk bracket” merely chooses the top seed in each individual matchup, resulting in a Final Four comprising the top four teams in the field, Dimers’ Ultimate Data Bracket recognizes that unexpected events often occur during the tournament. 

This bracket combines cutting-edge data with historical wisdom to give you the best possible chance to win your pool.

The odds of creating a perfect bracket are about 1 in 9.2 quintillion. Or put differently, roughly the same odds the Cowboys have of making the playoffs next year. (Sorry, we couldn’t help it.) 

Our point is, do not expect to go 63 for 63 with the Dimers Ultimate Data Bracket. The predicted results of these matchups are powered by industry-leading advanced simulations, not a crystal ball.

Want to set a (only slightly) more realistic goal for yourself? See if you can outdo Greg Nigl, the neuropsychologist from Columbus, Ohio, who holds the current record by successfully predicting the first 49 games of the 2019 tournament. 

Here’s hoping for 50!

At Dimers, we’re dedicated to delivering reliable sports predictions powered by cutting-edge tech and data-driven insights. Our team of data scientists and machine learning pros has built proprietary models that tap into the latest advancements in AI, machine learning and simulation techniques to break down every game with precision.

We start with collecting massive amounts of data—from historical stats to live, in-game updates at both the team and player level. Some of this data comes from external sources, while other key metrics we track ourselves. We then apply advanced statistical analysis to uncover patterns, pinpoint critical variables and refine our predictive models.

Our models process thousands of data points and weigh every possible factor—team and player performance, weather, starting lineups, home vs. away trends, projected minutes and more. The result? Data-backed insights that help you make sharper picks with confidence.
