March Madness Odds 2025: Duke Favored Over UConn

The UConn Huskies are back-to-back national champions after defeating Purdue in the 2024 national championship. Although the season just ended, now is a great time to look at the early 2025 March Madness odds.

Entering the offseason, the Duke Blue Devils are the betting favorites to win the 2025 college basketball championship over UConn. Those two are closely followed by the Kansas Jayhawks, North Carolina Tar Heels, and Houston Cougars.

Odds of Winning the NCAAB Championship: Best Bets

Here, we will break down the betting favorites to win March Madness.

Duke

The Duke Blue Devils have the best odds to win March Madness 2025. Not only are they projected to bring back a lot of production from last season, but they are also bringing in the best recruiting class in the country, headlined by the No. 1 ranked player, Cooper Flagg. 

As always, Duke will enter the season with one of the top rosters in the country. This is why they hold the top spot in current odds to win March Madness over the two-time defending champions. 

UConn

College basketball has a repeat champion for the first time since the 2006-07 Florida Gators. The UConn Huskies finished yet another historic run to the NCAAB title, knocking off fellow No. 1 seed Purdue. 

Over the last two championship seasons, UConn finished 12-0 ATS in the NCAA Tournament and has won 11 straight March Madness games by double-digits. In the modern era of basketball, we have not seen a team dominate like this. 

With its returning talent and more top-ranked recruits entering the program, a three-peat is not off the table, and the oddsmakers agree, giving Dan Hurley’s squad the second-best March Madness odds. 

Odds to Win March Madness: Longshots and Value Bets

Longshots rarely go on to win it all in March. However, a few programs can go on deep runs every season. In 2024, the NC State Wolfpack made it all the way to the Final Four as a No. 11 seed. There are also some excellent value plays to consider entering the offseason. Some of the best programs in the country are given a generous price below the favorites. 

Kansas 

Entering last season, the Kansas Jayhawks were projected to be one of UConn’s biggest competitors. That was true for the first chunk of the season, as Kansas knocked off the Huskies in December and was the No. 1 ranked team in the country. 

Injuries and overall roster regression cost Kansas a shot at competing. However, they are bringing back a nice chunk of last year’s production and have one of the best recruiting classes in the country. 

North Carolina 

The Tar Heels improved over a disastrous 2022 campaign, winning the ACC regular season title and earning a No. 1 seed in the tournament. While they ultimately fell in the Sweet 16 to Alabama, North Carolina will return in 2024 with a national championship-caliber rotation. 

Like most teams at the top of the early 2025 March Madness odds, they are bringing in some of the best freshmen in the country, which should complement an experienced returning roster. 

Where to Bet on NCAA Basketball Odds in 2024

How can you find the best sports betting apps for March Madness and claim the top March Madness betting promos?

The online marketplace for March Madness odds vary, sometimes wildly, and fluctuate regularly, putting those who have done their homework in the best positions to capitalize on March Madness bracket predictions. Incentives are aplenty, too.

March Madness Line Movement: Why Do Betting Lines Move?

Basketball game betting lines and championship futures can move for several reasons. One or both teams could have critical players ruled out. But the primary reason why a line will move is that a significant amount of money has been placed on one side of the bet. In such a situation, should that side of the bet win, the house loses. So, to protect themselves, sportsbooks will adjust the NCAAB odds to encourage betting on the other side of the line.

Unexpected line movements can happen when a lot of money is placed on one side of a bet by a small number of big bettors (sharps).

The same principle applies to future odds, i.e., March Madness tournament odds. But during the tournament, March Madness odds will move because there are fewer teams alive, and each remaining team has a better chance of winning simply because they are still playing.

What is Implied Probability?

Implied probability refers to the likelihood of a particular outcome based on the odds.  For example, DraftKings has listed the 2024 runner-up Purdue Boilermakers at +3000 odds to win the 2025 NCAAM Championship. Those odds would translate to a 3.23% implied probability of Purdue winning March Madness 2025.

You can use our implied probability calculator to determine the likelihood of your wager succeeding.

How To Bet On March Madness

Bettors looking to put money down on March Madness 2025 odds have several options they can choose from, including the following:

Point Spread

When you bet the point spread, you are betting on the margin of victory for a single game. The spread for underdogs will be listed with a (+); the number gets added to the team’s final score. You win your bet if that number is higher than the other team’s score. When you bet on the favorite, the March Madness spreads are listed with a (-) and get subtracted from the final score. So, if you bet on UNC (-7.5), you’ll need the Tar Heels to win by at least eight points.

Moneyline

Betting on the moneyline requires you to bet on one team to win straight up over the other. The number listed tells you how much you stand to win if you pick the winner.

Total

Sportsbooks will include a number representing the projected total score. Bettors can bet on whether the actual total score will be Over or Under that number.

Parlay

Parlays are great if you want the chance to win more money. Rather than place several individual bets, you place one bet comprised of several individual bets, called “legs”. The more legs in your parlay, the more you stand to win. However, miss one leg, and you lose the bet. College basketball parlays come with more risk and greater reward than single-event bets.

Prop Bets

Also known as proposition bets or props, prop bets are wagers on the occurrence or non-occurrence of an event other than the outcome of the game. Some states restrict prop bets for college events like March Madness.

Futures

Futures are long-term bets you can make on something that will occur in the future. Betting on who will win the national championship is the most common; other examples include betting on conference winners or betting on whether a team will make the Final Four.

Types Of March Madness Bets Available All Season

Online sportsbooks will offer future odds for the NCAAM and NCAAW National Championship throughout the season. But some will offer additional ways bettors can put money on odds to win March Madness. Outrights are the type of March Madness bets that bettors can find at sportsbooks throughout the NCAA season until the final matchup is determined:

  • Outright Winner: The most straightforward bet has players wagering on the team that wins the Championship. And, given the current March Madness odds, any winning bet would pay out a huge ROI (between +500 to > +10,000).

It is also not unusual to see odds for the exact matchup and the exact outcome once the Tournament gets underway. Most sportsbooks will also offer odds on teams to make the Final Four.

This list is also not comprehensive. Sportsbooks often try to get creative and offer odds on a market the competition does not. With an event like March Madness, the options are truly endless.

Here are a few trends that could be helpful for bettors as they decide on who to wager on:

  • No team seeded from No. 9 to 16 has ever made the championship game.
  • No. 1 seeds have a 25% chance of making the Finals and a 16% chance of winning.
  • No. 2 seeds have a 20.8% chance of making the Finals and a 9% chance of winning.
  • No. 3 seeds have an 11.8% chance of making the Finals and a 7.6% chance of winning.
  • The highest seed to win is No. 8 (Villanova in 1985).
