Sixteen games across the country Thursday opened up the first round of the 2025 NCAA Tournament and probably to some extent busted at least part of your March Madness bracket in the process. Maybe you picked High Point to take down Purdue or thought No.

The top betting favorites as the tournament begins: Florida and Duke are listed as co-favorites (+325), according to BetMGM Sportsbook. Auburn (+425) and Houston (+600) are next. The Sweet 16 from March 27 to 30 will put games in Newark, New Jersey (East Regional), Atlanta (South), Indianapolis (Midwest) and San Francisco (West).

The SEC got a record 14 teams in the tournament, but went 8-6 in the first round. Of those eight wins, seven came against teams seeded 11th or worse. Other than Arkansas’ win over Kansas, the league lost almost all of the toss-up games.
