The new college basketball season has tipped off, bringing March Madness odds back into focus as Danny Hurley and the UConn Huskies try to become the second school ever to three-peat as champions.
The 4-0 Huskies top the college basketball odds board thus far, but they are not clear-cut favorites, as plenty of familiar blue bloods are right alongside them.
Here are the latest odds to win 2025 March Madness, with the Final Four scheduled for April 5-7 in San Antonio, Texas.

March Madness favorites
It's no surprise that two-time defending champion UConn is the favorite, sitting at +850, but for the second straight year, Hurley will try to extend the program's dominance with almost all of his top contributors gone — Alex Karaban is the only returning player among the Huskies' top five scorers from last season.
UConn was also just No. 3 on the preseason AP poll: No. 1 was 5-0 Kansas (+850 to +1,000), who has Hunter Dickinson, KJ Adams Jr., and Dajuan Harris firing on all cylinders to begin the season.
There is also the case of the 4-1 Duke Blue Devils, who are third on the odds board in the 10/1 range and have the nation's No. 1-ranked freshman (and projected first-overall NBA Draft pick) in Cooper Flagg, because, well, it's Duke.
Jon Scheyer's squad is currently the biggest betting liability at BetMGM, leading all schools with 18.5% of the betting handle and 15.6% of all tickets to cut down the nets in April.

What is March Madness?
March Madness refers to the annual NCAA Division I men's basketball tournament, which takes place in March and April. It is one of the most popular sporting events in the United States and involves 68 college basketball teams from across the country competing in a single-elimination tournament to determine the national champion.
The tournament begins with Selection Sunday, which takes place on the second Sunday in March, where the teams are announced and the tournament brackets are revealed. The first round, also known as the First Four, takes place on the Tuesday and Wednesday after Selection Sunday. The main tournament, consisting of 64 teams, then begins on the Thursday and Friday of the first full week of March.
The teams are divided into four regions, each containing 16 teams, and are seeded based on their regular-season records and performance in their respective conference tournaments. The teams then compete in a series of games, with the winners advancing to the next round and the losers being eliminated.
The tournament culminates with the Final Four, which takes place on the first weekend of April, where the remaining four teams compete in two semifinal games, with the winners advancing to the championship game to determine the national champion. Check out our Final Four odds page to see which teams are most likely to advance to the NCAA Tournament's semifinal round.
March Madness odds explained
Sportsbooks will post odds for the NCAA men's basketball championship as early as the summer before the season starts. These odds are constantly adjusted throughout the offseason as players get hurt, suspended, or are traded. Once the season begins in November, title odds will change as often as daily as teams win and lose games and as players get hurt or suspended. Sportsbooks will also adjust the March Madness futures odds based on handle and liability to certain teams.
March Madness futures odds will usually look like this:
- San Diego State +550
This means that on a $100 bet, you'll stand to win $550 if the Aztecs win the NCAA men's basketball title. If it's close to the end of the regular season or even during the tournament and college basketball has a very dominant team, you might see that a team has a minus sign (-) ahead of its odds.
- UConn Huskies -120
This means that you would need to bet $120 to win $100 on a UConn championship.

How to bet college basketball futures
Learning how to successfully bet on March Madness is one of the hardest things to do in sports betting. The lose-and-go-home format of the NCAA Finals and the fact that a school needs to win six straight games against quality opponents means that the favorites don't always take home the title.
Another factor that comes into play is that the tournament bracket isn't set until Selection Sunday. As the college basketball season winds down, you can be pretty sure that the big favorites will slide into the bracket as top seeds. But for teams in the middle of the pack, nothing is certain.
As always when betting futures odds, be sure to look into injuries and suspensions. You might find some current value in a team that is expecting to get a key player back before March Madness begins.

The term "March Madness" was originally used to describe the excitement and frenzy surrounding the Illinois High School Association's annual basketball tournament in the 1930s. However, the term became more widely associated with the NCAA Division I men's basketball tournament in the 1980s. The term "March Madness" is believed to have been coined by Brent Musburger, a CBS sportscaster, during the network's coverage of the tournament in 1982. Musburger used the term to describe the unpredictability and excitement of the tournament, as well as the intense emotions and high stakes involved in each game. The term quickly caught on with fans and has been used ever since to describe the annual tournament. Today, March Madness has become a cultural phenomenon and a highly anticipated event for basketball fans across the United States.
Calculating March Madness odds involves assessing the probability of different outcomes in the tournament. Oddsmakers use various factors including team performance, player health, head-to-head matchups, tournament experience, coaching, venue, and advanced statistics. Bookmakers use these factors to set initial odds, and as bets are placed, odds may shift based on the money wagered on each side.
The only other school to win three-straight national championships is UCLA, who actually won seven straight titles from 1967-1973.
