The Hottest Teams and Their NCAA Basketball Championship Odds

Gonzaga (+350): Losing top players like Jalen Suggs, Corey Kispert, and Joel Ayayi doesn’t seem to have derailed last season’s finalist. The duo of Chet Holmgren and Drew Timme is cooking this year and all opponents should fear the strong bite of the Bulldogs.

Arizona (+650): The Wildcats, led by first-year coach Tommy Lloyd and two-way star Azuolas Tubelis, defied their opening odds to win the NCAA Championship with some impressive displays. The wins against Michigan and Illinois were the ones that made everyone else take notice.

Kentucky (+700): Another team nicknamed the Wildcats is making headlines this season. Kentucky’s stud is definitely Oscar Tshiebwe who seems more than capable to lead Kentucky on the way to glory.

Duke (+1200): This version of the umpteenth great team of Mike Krzyzewski is ready to make some noise. Trevor Keels and Paolo Banchero are the new Blue Devils stars and Wendell Moore is a great help for the duo.

Baylor (+1200): The defending champion can produce the first title repeat since Florida in 2006-07 despite losing four of five starters from its team from last season. Scott Drew’s Bears are one of just five teams ranked in the top 15 in both adjusted offensive and defensive efficiency. Their odds to win the NCAA Championship remain tempting.

Auburn (+1200): Bruce Pearl’s Tigers found form at just the right time with Walker Kessler and Jabari Smith destroying opponents. To top it off, their top gun Allen Flanigan is back with a bang after being out for months because of an Achilles tendon surgery. The stars have aligned for Auburn and their March Madness odds seem a great deal as of today.

Kansas (+1400): The Jayhawks have four of their top five players back (Ochai Agbaji, Jalen Wilson, Christian Braun, and David McCormick), so Bill Self has good chances to clinch his first national title since 2008. Their NCAA Tournament odds deserve your attention as bettors.

Purdue (+1400): The Boilermakers are one of the best offensive teams in the US, ranking 1st in adjusted offensive efficiency at, but their problem is that they don’t show up at the other end of the floor this year (103rd). Matt Painter’s team still has appealing odds to win NCAA Tournament and front court stars Zach Edey and Trevion Williams can do some damage helped by guard Jaden Ivey.

March Madness Odds: Understanding The Betting Markets

Learn how to bet on March Madness betting odds and lines with our detailed examples

Having knowledge on NCAAM odds means that you’ll be well aware of how to navigate successfully between the different betting markets that are available for the NCAA Tournament. The main markets we will look at here are the Spread, the Over/Under, the Moneyline and the Future. Later, we will also take you through the process of registering with one of the best online sportsbooks around for NCAA March Madness betting odds.

For the purposes of illustration, practical examples of various points will be given where necessary. All such examples will focus on a hypothetical matchup between a No. 4 Seed and a No. 1 Seed.

Point Spread March Madness Odds

Spread betting, or betting against the spread, is a common wager that can be made on any NCAA March Madness game. All online sportsbooks will set the point spread based on their perceived probability of a certain outcome taking place. It is then up to the bettor to make a pick.

No. 1 Seed-4.5-110
No. 4 Seed+4.5-110
NCAA March Madness Spread Example

Sportsbooks will almost always offer the same odds at -110 for all NCAA March Madness spreads. That means you would need to wager $110 to make a profit of $100 if your bet wins.

The No. 1 Seed is the favorite here. We see that because there is a (-) sign before their spread figure. In this case, 4.5 points will be deducted from their score before the sportsbook settles your bet. In other words, because they are the favorites, they will need to win by 5 points or more for your wager to win.

The No. 4 Seed are the underdogs. They get a (+) sign before their spread figure. That figure is added onto their points total before your bet is settled. If the team wins, so do you. However, because of the +4.5, your wager would also win even if they were to lose by 4 points or less.

If you’ve grasped the March Madness point spreads concept, it’s time to try your newly gained knowledge and place a bet with the online sportsbook of your choice.

March Madness Money Lines

The NCAA March Madness money lines are the easiest bets to understand because they only require you to pick the winning team. This type of wager is less common during the regular season, but it is quite popular in the NCAA Tournament due to the potential for huge upsets.

Consider the following example:

No. 1 Seed-135
No. 4 Seed+145
NCAA March Madness Money Lines Example

The No. 1 Seed is the favorite in this matchup, and so the payout is not as great if they win. Odds of -135 mean that you would need to bet $135 to make a profit of $100 if your bet succeeds.

Meanwhile, the No. 4 Seed are the underdogs at odds of +145. A $100 wager on this team would therefore give you a profit of $145 if the team wins.

The NCAA Tournament is known as March Madness for a reason, and that's because upsets occur quite frequently. Of course, this means you can find better odds at this stage of the season compared to the previous ones. Because of that, you’ll have to make sure you gamble responsibly when trying to take advantage of appealing March Madness betting lines.

March Madness Betting Odds for Over/Under

The Over/Under bet is sometimes referred to as a 'total'. This type of betting market focuses on the total number of points that will be scored in a game. It is therefore completely unnecessary for you to predict which team will win or lose.

Because it doesn't force anyone to choose a side, this wager is particularly popular and is considered one of the best March Madness bets. Let’s look at the example once again. 

Over 143.5 Points-110
Under 143.5 Points-110
NCAA March Madness Over/Under Example

Here you will see that the sportsbook has set the line at 143.5 points. If you think that the total number of points scored by the two teams will be 144 or higher, you would bet Over. On the other hand, if you consider that it will be 143 or lower, you would bet Under.

Again, note that these March Madness odds in our example are the same for both outcomes. Sometimes though, they will differ. This is called ‘juice’ or ‘vig’.

Parlays for Multiplying Your March Madness Odds

The NCAA Tournament offers lots of quality parlay betting opportunities with some very enticing odds. If you don't already know what a parlay bet is, don't be alarmed, it is very simple. The basic premise is that you are stacking a few different odds into one. If they all come in, you win. The problem is that If even one doesn't come in, you lose. Parlay betting is a good way to increase your odds with outcomes that are not extremely out of the ordinary. Some sportsbooks even offer ‘same game parlays’ for bettors who concentrate their research efforts into a single matchup.

Parlays can result in some crazy wins and some heartbreaking loss stories. This is definitely a fun betting type to go with during March Madness.

March Madness Live Betting

In-play wagering is another great option for March Madness betting. It can not only make you some nice profit, but also enhance the NCAA game watching experience.

Like in most sports or sporting events, the lines can change throughout the game. Watching the spreads, money lines and totals to find the best figures can be a very fun way to follow a matchup. It isn't often that a college team will hit over 100 points in a 40 minute game, but if you think a particular school has a chance, this is a March Madness live bet that you can place.

Another popular March Madness live betting type to consider is the live props available during games. Not only are these wagers fun to make, but they can also make you a quick buck. One of our favorites here at How To Bet is betting on who will get the next basket. Basketball is a very dynamic and fast moving sport which makes for a plethora of live bets available during games.

How to Bet on March Madness Odds for Futures

Learn how to make future bets on March Madness betting odds and lines

Futures betting involves making predictions about events that are more long-term than the next game. There are three very common future wagers that are made during March Madness. They are:

  1. Who will win the NCAA Championship?
  2. Who will make it to the Final Four?
  3. Which team will be the No. 1 Seed?

The first wager can be made well in advance of the tournament, and you can continue making these future bets all the way until the Final Four. You can check some of the current March Madness betting odds for the first two bets at the beginning of this page, if you have somehow missed them.

The Final Four bet is usually opened up after the brackets have been unveiled. A future bet on which teams will earn No. 1 Seed will open when the season begins, and close right before the brackets are announced. 

March Madness Prop Bets

Prop betting was created during the Super Bowl but has very much been brought into other sports. NCAA Basketball makes no exception. Sportsbooks will offer lots of golden team/ player/ event odds for March Madness prop bets.

These can range from more wacky picks, for example 'How many dunks will be made in a game?', to more serious player props such as 'Jared Butler to get a triple-double’.

So whether you're wagering a small amount of dough on a wacky offer for fun, or going for a more serious, researched player prop, there are always some March Madness betting odds for you!
