About BracketOdds 2025

Welcome to bracketodds.cs.illinois.edu, a website to evaluate seed distributions in the NCAA Division I Men’s Basketball Tournament, commonly referred to as March Madness. This tool uses principles from probability theory, operations research, and artificial intelligence to model the likelihood that a set of seeds will reach a particular round of the tournament. The analytics behind this tool can be found in several peer-reviewed academic journal, which can be found on the main page.

Please use this website as it was intended, namely, a tool to evaluate and compare various seed combinations of your bracket and to assess your bracket odds. Hopefully it will provide you with added enjoyment in not only assessing your own bracket, but also, to retrospectively measure the likelihood of the set of seeds that reach the Elite Eight, the Final Four, the National Finals, and the National Champion.

Numerous individuals have worked to make this website possible. Let us celebrate the accomplishments of the 1800+ student athletes on the 136 mens and women teams participating in this year’s tournament, without which March Madness could not exist. The efforts of Ammar Rizwan and Emon Dai, undergraduate students in the Department of Computer Science at the University of Illinois at Urbana-Champaign who worked on this project in 2011, was critical in transforming a research idea into the website. Andrew Yang added several substantial contributions to the web site in 2015. Abhinav Singh added the women's simulator to the web site in 2019. The final product is a product of the talented and creative students in the Department of Computer Science (College of Engineering) at the University of Illinois at Urbana-Champaign. Douglas M. King (University of Illinois at Urbana-Champaign), Adrian J. Lee, Alexander G. Nikolaev (University of Buffalo) and Arash Khatibi were most helpful in providing feedback during the nascent stages of the website’s development. Ian Ludden (Rose Hulman) and Nestor Bermudez Sarmiento have also contributed to this research. All these individuals deserve credit and accolades for their hard work and impressive effort. Any oversights or shortcomings of the website are mine alone.  

Lastly, enjoy the madness brought to us during the 19 days and 67 games of the tournament. In a world filled with challenges and disappointments, the tournament provides a brief respite from the many problems each of us face, both individually and collectively. Keep a grounded perspective of what we are enjoying, and what we truly should be grateful for.  

Let the games begin!
