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 six games in its quest for a third-straight National Championship, dropping them to +5500 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.

auburn Favored To Win 2025 National Championship at +375

Over the last week, Auburn has climbed slightly ahead of Duke on the oddsboard. It's not the fault of the Blue Devils, but rather the Tigers resume stacking up as they naviagte a hefty remaining ranked schedule. Star Johni Broome remains. The best player in college basketball, Broome and fellow big man Dylan Cardwell continue to crush the opposition. 

KenPom lists Auburn first in his rankings, with the highest offensive rating in the country, and a net rating of plus-36.38. Despite going 8-1 SU against ranked competitors by the beginning of February, that early December loss to Duke is still stinging. 

The road to March is long for the Tigers, who are currently set to meet seven more ranked programs—including rounding out the regular season with four-straight clashes against Ole Miss, Kentucky, Texas A&M and Alabama. We'll see if the Tigers truly earn their stripes. 

National Championship contenders: duke, +400

Duke sits third in the KenPom ratings, boasting the third-best defensive and fifth-best offensive ratings, making them just one of three programs to sit in the top 10 for both areas. The Blue Devils suffered to losses in the opening month of the season, but haven't felt defeat since—with a 84-78 victory over No. 2 Auburn still it's most impressive win to date. Even the two losses were within five-points or fewer to a talented, ranked Kentucky and Kansas program. 

The success is largely resting on Cooper Flagg's shoulders, who's expected to be just the fourth true freshman to win the Wooden Award. He is averaging 24.8 PPG since the New Year, 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 (13.5 PPG) and Tyrese Proctor (10.7 PPG) are also making their presence known on the court.

Duke is looking to hoist its first national title in a decade. But, the ACC is a little light with Jon Scheyer only set to meet one more ranked school before March blooms.

NCAAB National Champion Darkhorse: Iowa State +1100

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 suffered four shocking upsets, three of which were unranked, between mid-January and the beginning of February, yet their odds didn't drastically drop.

KenPom ranks the Cyclones 10th in his adjusted efficiency rankings. Iowa State nobly stands with the sixth best defensive showcase. When combined with their notoriously stingy defense, allowing 67.6 PPG, the Cyclones new found offensive chops, averaging 81.6 PPG has shown a glimmer of promise that can regroup and play well come March.

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.

How to Bet on March Madness

Betting on March Madness has become increasingly popular for even the most casual of college ball fans.

There are other options for futures too, like selecting the Final Four or individual conference winners.

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.
