The Official Start of March Madness 2026
Although the bracket reveal happened on March 15, the games themselves begin a few days later with the opening round known as the First Four.
The First Four games take place March 17 and March 18 in Dayton, Ohio. These matchups determine the final teams that will enter the main 64-team bracket.
This stage features lower-seeded teams and at-large squads battling for a place in the tournament’s main field. While they are technically play-in games, they often produce dramatic finishes and occasionally introduce teams that later become Cinderella stories.
First Round of the NCAA Tournament
After the First Four wraps up, the main bracket begins.
The first round of the 2026 NCAA Tournament starts Thursday, March 19, marking the traditional beginning of the most intense stretch of March Madness.
Games continue through Friday, March 20, with 32 matchups played across several host cities in the United States.
These early rounds are where many of the tournament’s famous upsets occur, with lower-seeded programs attempting to knock off national powerhouses.
Host cities for early-round games include locations such as:
- Buffalo, New York
- Greenville, South Carolina
- Oklahoma City, Oklahoma
- Portland, Oregon
- Tampa, Florida
- Philadelphia, Pennsylvania
- San Diego, California
- St. Louis, Missouri
The nationwide format allows fans across the country to attend games in person while giving teams a neutral-site environment.
Second Round and the Race to the Sweet 16
The second round takes place March 21 and March 22, trimming the field from 32 teams down to 16.
This stage determines which teams will advance to the Sweet 16 and remain in contention for the national championship.
By the end of the weekend, half of the remaining teams will be eliminated, leaving only the strongest programs and a few surprising underdogs still alive in the bracket.
Sweet 16 and Elite Eight Matchups
The tournament moves into its regional rounds the following week.
Sweet 16 games are scheduled for March 26 and March 27, followed by the Elite Eight on March 28 and March 29.
These rounds determine the champions of the four tournament regions. Each regional winner earns a spot in the Final Four.
At this point in the tournament, the level of competition intensifies dramatically as top-seeded teams clash with programs that have survived earlier upsets.
Final Four and National Championship
The final stage of the tournament will take place in Indianapolis, Indiana, one of college basketball’s most historic cities.
The Final Four is scheduled for Saturday, April 4, 2026, at Lucas Oil Stadium.
