Major upsets are a big part of what makes March Madness so special.
The No. 2 vs. No. 15 matchups always offer intrigue, as we’ve seen David topple Goliath many times throughout the years.
Below, we will look at the history of 15 seeds versus 2 seeds in the NCAA men’s basketball tournament.
How many times has a 15 seed beaten a 2 seed in March Madness?
In 156 NCAA Tournament matchups, the 15 seed has knocked off the 2 seed 11 times. That’s a record of 11-145.
So, it happens... just not every year.
We did not see a 15-seed win last year. In 2023, however, Princeton stunned 2-seed Arizona.

Crazy enough, that was the third straight March in which a 15 seed won a game. In 2022, Saint Peter’s shocked Kentucky, and in 2021 Oral Roberts defeated Ohio State.

What are the odds that a 15 seed wins against a 2 seed?
Teams seeded No. 15 have a 7.05% chance of beating a 2 seed. These odds are increasing over time, likely due to more and more parity in college basketball.
Consider that in the 1990s, a 2 seed beating a 15 seed occurred just three times. In the 2000s, it happened just once.
The turning point happened early in the 2010s. In 2012, there were a pair of No. 15 vs. No. 2 upsets in the same tournament. Another came in 2013, and yet another came in 2016.
There have been three so far this decade, and we aren’t even halfway through it.
