March Madness Betting Guide for 2025

It is now officially March Madness season, as the 2025 NCAA Division I men’s and women’s basketball tournaments tip off this week.

With 67 games to bet on in each tournament, there is plenty of action to bet on until the season wraps up early next month. And that’s not even taking into consideration the NIT and other men’s and women’s postseason tournaments for the teams that didn’t make it to the Big Dance.

BetOnline, where you can find both men’s and women’s NCAA Tournament odds, is one of the best March Madness betting sites, if not the best. There’s no better time to check them out than now, especially because of their $200,000 Bracket Madness contest, which offers a grand prize of at least $50,000.

Men’s and Women’s 2025 March Madness Brackets

The field of 68 is now set for the men’s and women’s NCAA Division I basketball tournaments.

In the men’s tournament, the four #1 seeds are Auburn (top overall seed and #1 in the South Regional), Duke (East Regional), Houston (Midwest Regional), and Florida (West Regional).

There are four first timers in the 2025 men’s March Madness bracket. Leading the way is UC San Diego, who will be a popular upset pick after going 30-4 and winning the Big West’s automatic bid in their first season of NCAA Division I tournament eligibility. Additionally, High Point (Big South), Omaha (Summit League), and SIU Edwardsville (Ohio Valley) are debuting in the Big Dance.

In the women’s tournament, the four #1 seeds are UCLA (top overall seed and #1 in the Spokane 1 Regional), South Carolina (#1 in the Birmingham 2 Regional), Texas (#1 in the Birmingham 3 Regional), and USC (#1 in the Spokane 4 Regional).

UC San Diego’s women’s team is also a first timer in the 2025 women’s March Madness bracket, as are Arkansas State (Sun Belt), Fairleigh Dickinson (Northeast Conference), George Mason (Atlantic 10), Grand Canyon (WAC), and William & Mary (CAA).

There are many interesting potential matchups and storylines in each tournament.

In the men’s tournament, two Hall of Fame coaches could meet in the second round in the West Regional if Kansas (Bill Self) and St. John’s (Rick Pitino) both advance. In the women’s tournament, Hailey van Lith and TCU could face Louisville, where she played three seasons, in the second round after a record-breaking season for the Horned Frogs, who are the #2 seed in the Birmingham 3 Regional.

Check out the complete brackets, seeds, and schedules for both tournaments here.

March Madness

During the course of March Madness this year, we will have picks and analysis for dozens of games. Here, you can find our round-by-round predictions and picks, starting with the First Four, which will begin on Tuesday, March 18 in Dayton, Ohio.

Our team of college basketball writers (Eddie Griffin, Nate Hornung, and Colby Marchio) will have predictions and picks for many men’s and women’s matchups over the course of the tournament, and we will also carry college basketball moneyline, spread, and over/under computer picks for each men’s tournament matchup from the First Four to the Final Four.

While we provide information we wholeheartedly believe in, we also don’t think we should be the only source you use for March Madness picks. With that in mind, there are a few sports handicapping services that we think are worth checking out.

The women’s Final Four will be held at Amalie Arena in Tampa, Florida, which previously hosted the women’s Final Four in 2019. That year, Notre Dame lost to Baylor in the championship game. This year, the Fighting Irish will be one of the Final Four favorites, as will defending champions South Carolina, Texas, UConn, and rivals UCLA and USC, who have dazzled in their Big Ten debuts.
