Perfect March Madness Brackets Dwindle After First Round
The first round of the 2026 NCAA Division I men's basketball tournament concluded on Friday night, significantly reducing the number of remaining perfect brackets submitted across major platforms.[1]
The NCAA Division I men's basketball tournament, known as March Madness, is a 68-team single-elimination event held annually in March to determine the national champion.[1] It begins with four opening-round games known as the First Four, followed by the round of 64 (first round), round of 32 (second round), Sweet 16, Elite Eight, Final Four and championship game.
The NCAA's official Bracket Challenge tracks public predictions for all 63 games, typically attracting tens of millions of entries each year.[2] Perfect brackets—those correctly predicting every outcome—are exceedingly rare due to the tournament's unpredictability, with upsets common even among top seeds.
Historically, the number of perfect brackets drops dramatically after the first two days of competition. For example, in recent tournaments, thousands may survive the opening day but only dozens or fewer enter the second round.[2]
Second-round matchups on Saturday featured higher seeds advancing in most cases, further challenging remaining perfect entries. Key games included top seeds facing lower-seeded upset winners from the first round.
The tournament continues with the second round through Sunday, leading to the Sweet 16 the following week.
