The NCAA March Madness tournament is always a whirlwind of excitement, and the 2025 edition kicked off with a bang. On Thursday, March 20, 2025, the men’s basketball tournament began, drawing millions of fans and bracket enthusiasts eager to predict the unpredictable. With over 34 million brackets submitted, the stakes were high, but by the end of the first day, only 36,000 brackets—less than 1%—remained perfect. The tournament’s opening day was filled with thrilling upsets and heart-stopping moments, proving once again why March Madness is one of the most unpredictable events in sports.
The first day of the tournament saw several notable upsets that sent shockwaves through the bracket pool. McNeese State University, a No. 12 seed, pulled off a stunning victory over No. 5 seed Clemson University with a nail-biting 69-67 win. This upset alone slashed the number of perfect brackets from 11 million to under 2 million. Arkansas, a No. 10 seed, added to the chaos by defeating No. 7 seed Kansas 79-72, further reducing the number of flawless brackets to less than 1%. Drake University, a No. 11 seed, also made waves by toppling No. 6 seed Missouri 67-57, cutting the remaining perfect brackets by more than half. The tournament’s opening game, where Creighton University defeated the University of Louisville 89-75, busted over half of the submitted brackets right out of the gate.
For those brave enough to attempt a perfect bracket, the odds are astronomically low. ESPN reported that only 540,000 brackets remained perfect after the first eight games, out of 24.3 million submitted. The chances of picking a perfect bracket are 1 in 9.22 quintillion if guessing randomly, or 1 in 120.2 billion with some knowledge of NCAA basketball. Despite these daunting odds, the rewards for coming close are enticing. X (formerly Twitter) is offering a trip to Mars or $250,000, along with a SpaceX astronaut training experience and a Starship launch viewing. ESPN is randomly awarding 20 grand prizes of $5,000 for predicting the national champion, while USA Today Sports is dangling a $1 million prize for a perfect bracket. The NCAA Bracket Challenge Sweepstakes is also offering two tickets to next year’s Final Four, a four-night hotel stay, $1,500 for airfare, and $750 in spending money.
Historically, no one has ever submitted a verifiably perfect March Madness bracket. The closest anyone came was in 2019, when an Ohio man correctly predicted 49 out of 63 games, only to lose his streak in the Elite Eight. This year, Duke University is the favorite to win the tournament, with +320 odds, meaning a $100 bet could win $320. Other top contenders include the University of Florida (+380), Auburn University (+450), and the University of Houston (+600).
The 2025 NCAA March Madness tournament is off to a thrilling start, with unexpected upsets and dwindling perfect brackets. As the tournament progresses, fans will be on the edge of their seats, cheering for their favorite teams and hoping their brackets survive the chaos. Whether you’re a die-hard basketball fan or just in it for the fun, March Madness never fails to deliver unforgettable moments.
