Updated 2025 March Madness odds have been released. Chaos reigns supreme through the first few months of the men's NCAA basketball season. The UConn Huskies have lost nine games in their quest for a third-straight National Championship, dropping them to +8000 odds to repeat.

Here's a look at the full list of college basketball national championship odds, where Auburn and Duke are constantly exchanging possession at the top of the oddsboard. Now, they are co-favorites with +350 oods at Site.

At the end of February, Auburn climbed slightly ahead of Duke on the oddsboard. But, back-to-back losses to wrap up the regular season now forces them to share the top spot. The dagger was a 93-91 OT home loss to Alabama, a team which it proved to beat earlier in the season. KenPom suggests Auburn has been playing through the second toughest overall schedule, going 10-4 SU against ranked programs. 

KenPom lists Auburn second in his rankings, with the highest offensive rating (129.7) in the country, and a net rating of plus-35.85. Even with a couple of injuries, Johni Broome can't be kept sidelined. The senior is averaging 18.6 points and 10.6 (ranked eighth) rebounds per game. Recording a double-double in eight of 14 meetings against ranked opponents, one of the exceptions being November's matchup vs Houston where he was one rebound shy of hitting the mark, Broome saves his best for the best. Anyone would feel confident heading into the Big Dance with the best player in college basketball on wearing their jersey. 

National Championship contenders: duke, +320

If you're wondering why Auburn's odds didn't budge despite the upset in early February, it's probably because Duke was devastated the same day thanks to Clemson. The Tigers somehow held Cooper Flagg to 35.3% from the field, his worst mark since early December.

Still, Duke sits as a co-favorite oddsboard and favorite in the KenPom ratings, boasting the fourth-best defensive and second-best offensive ratings. It makes them just one of three programs to sit inside the top 10 for both areas. The Blue Devils have suffered just three losses, two which were in the opening month of the season. The two losses in November were within five-points or fewer to a talented, ranked Kentucky and Kansas program. Duke's 84-78 victory over No. 2 Auburn still it's most impressive win to date. 

The success is largely resting on Cooper Flagg's shoulders, who could be the fourth true freshman to win the Wooden Award. He is averaging 19.4 PPG this season, including a 42-point performance that broke the Duke and ACC Freshman scoring record. But, perhaps the most lethal element of the Blue Devils roster is that Kon Knueppel (13.7 PPG) and Tyrese Proctor (12 PPG) are also making their presence known on the court. Duke is looking to hoist its first national title in a decade. 

NCAAB National Champion Darkhorse: Iowa State +2500

Iowa State was just a few plays away from defeating Auburn and earning their place atop the March Madness odds earlier this season. They lost on a last second Broome tip-in. The Cyclones have four ranked wins under their belt, but also carry three ranked losses. Iowa State's biggest downfall is four unranked losses, all of which should've been wins to help boost its status as national championship contenders.

KenPom ranks the Cyclones 10th in his rankings as Iowa State nobly stands with the 11th best defensive showcase. When combined with their notoriously stingy defense, allowing 67.2 PPG, the Cyclones new found offensive chops, averaging 80 PPG has shown a glimmer of promise.

Last 10 College Basketball National Champions

With their 2024 March Madness win, UConn is the only three-time champion in the last ten years. Coincidentally, the Huskies have the longest odds to win a championship on this list. In 2014, they had the 14th-longest odds at +6500 and in 2023 they had the 28th-longest odds at +8000. As you know, they won both times, so disrespect UConn at your peril.

NCAA Basketball Teams with the Most Titles

Holding the league record for March Madness titles and longest win streak (seven years), the UCLA Bruins are the clearcut college ball champion. I mean, the John R. Wooden Award for Player of the Year is named after their head coach during that insane streak – what more of a legacy could you ask for?

Trailing UCLA are the Kentucky Wildcats and UNC’s Tar Heels with an impressive eight and six titles respectively – this year, UCLA is further down the odds list than either of these teams. It’ll be a few years before they can be dethroned, but there are undoubtedly expectations for UCLA to keep producing and earn their first title since 1995.

Understanding The Odds To Win The NCAA Championship

If you’re interested in March Madness futures, you’re likely looking to bet on the outright winner of the tournament. Like the odds table at the top of the page, odds will usually look like this:

These odds tell you the likelihood and corresponding payout of one of these teams winning a national championship. Unlike a moneyline bet, where there is a clear favorite represented by a minus sign (-), the team with the lowest odds would be the favorite. In our example, it’s Gonzaga, and the rest are underdogs even though each team has a plus sign (+) prefacing its odds.

If you were to bet $100 on the Gonzaga Bulldogs and they won, your sportsbook would reward you with $200 in profit for a $300 total win. Betting on a long-shot winner like UCLA at +2500 would earn you $2500 on that same bet – the profits are much higher the further you go down the table, but so is the risk.

To see how much you’d win on the futures odds, check out our Odds Calculator. It’ll show you what your payout would be based on the odds and amount wagered. Don’t forget you can also make selections on which teams will make the Final Four, who will win each conference, and which player will take home the John R. Wooden Award for Player of the Year in the regular season.
