The final piece of confetti has not yet fallen on the 2023/24 season, yet here we are talking about March Madness odds — in particular, the 2025 college basketball National Championship odds.
Despite defending their crown, the UConn Huskies are not the betting favorites to three-peat. Instead, the Duke Blue Devils lead the way on the heels of a disappointing season by their lofty standards.
Beyond those two, the Kansas Jayhawks and North Carolina Tar Heels are teams to keep an eye on with odds of +1,400 and +1,500, respectively.
This year's runners-up, Purdue sits at +3,000 to cut down the nets next year in San Antonio.
Join me as I break down the 2025 National Championship odds below.
March Madness 2025 odds
With the 2023/24 season done and dusted, the odds are now out for who will win next season. Things look good for those supporting either of the Tobacco Road schools, as the Duke Blue Devils are early favorites to win next season, while UNC is right behind them — along with UConn, Kansas, and Houston — but a lot (and we mean A LOT) can change with the transfer portal.

Where can I bet on March Madness?
March Madness is one of the busiest times of the year for online sportsbooks and is very popular with bettors. Every betting site will offer March Madness odds, but the best sites are safe and secure, offer a wide range of banking options, and give you a ton of markets for each game. Check out the best March Madness betting sites in your region.
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.

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.
