HOW TO READ 2025 MARCH MADNESS ODDS
Want to bet on a team to simply win the game? Select that team along the moneyline ticket. That’s just a straight-up win prediction.
Avoiding betting on winners and losers directly? Consider markets on teams covering NCAA Tournament spreads. This way, you can bet either (1) by how much the favorite wins or (2) that the underdog loses by a certain amount. For example, a side might say Duke is favored by 6.5 points (-6.5) over North Carolina (who would be listed at +6.5), saying Duke will either win by seven or more points or UNC will lose by 6 points or fewer. Depending on your game analysis, you can bet either end of that total.
Don’t care about NCAA Tournament game results? Bet the game’s total points, or Over/Under: Will the two teams combine to score more or fewer points than the sportsbook’s given total?
In states where it’s legal to bet player props on college athletes, we can find markets like Over/Under points scored, rebounds collected, or assists dished out. More CBB props include a team winning in the first or second half of the game only, race to 20 total points, and more offshoot betting opportunities for tourney action.

March Madness betting ODDS history: POINT SPREADS, MONEYLINES & TOTALS
The first NCAA basketball tournament took place in 1939 in Evanston, Illinois. Since then, 37 teams have won it all. Five teams have won the tournament at least five times (Indiana, Duke, UNC, Kentucky, UCLA). Since seeding began in 1979, No. 1 seeds have won the tournament 25 times, accounting for almost 49% of all championship appearances. Just three times has a team that’s been lower than a four seed won the title. No team seeded below eighth has won, nor has such a team made a championship appearance.
Since betting lines were released for NCAA tournament games in 1985, underdogs in March Madness odds have covered 44% of the time, winning outright 29% of the time. Games have gone under the total 56% of the time. Since 2010, 70% of games have gone under the total, and favorites have covered in seven out of 10 games. Three teams have won more than one championship since 2010 (Duke, UConn, Villanova). None have won back-to-back titles (despite Butler and UNC appearing in back-to-back title games).
Since 2000, the top overall seed has made the championship game just four times, but it won the game three of those times (75%). The top overall seeds in the tournament have comprised just 8% of the total Final Four teams (missed 13 out of 20 years). Besides No. 1 seeds, No. 2 seeds have the most championship appearances since 2000 (seven times), followed by three seeds (six times), and five and eight seeds (two).
Just 8% (52/640) of all Sweet 16 teams have been seeded 11 or lower. Only 2.8% of teams in the Elite Eight were seeded 11 or lower. Four 11 seeds advanced to the Final Four (Loyola Chicago, 2018; VCU, 2011; George Mason, 2006; LSU, 1986). UMBC and Fairleigh Dickinson are the only No. 16 seeds to upset No. 1 seeds in the tournament’s history (2018 and 2023), and just eight 15 seeds have prevailed (5%). In 2015, two 15 seeds upset two seeds (25% of all such upsets), and two 14s upset threes.
Exercise caution with historical data when filling out brackets and betting on March Madness. Stats should be used in the long run. But when choosing individual games, study matchup statistics. The most important thing to remember, though, is this is March Madness. Anything can (and will) happen.
Tournament betting strategies
The historical ATS data for each team in tournament play is just one of countless data points that can constitute March Madness odds betting research. Here are some other factors that can hold considerable relevance:
- A team’s late-season performances, including in its conference tournament
- Key Injuries
- A team’s defensive proficiency typically has more carryover into tournament play than a high-powered offense
- “Fading the public” when the line appears to be significantly affected by a team’s popularity, as opposed to actual recent performance
Examine tournament-specific historical trends, such as how high-seeded mid-majors have done in each round regarding straight-up wins and losses.
Another overarching data set that could prove highly valuable is the performance of each seed in each round versus the spread.
How the NCAA Tournament works
March Madness is a 68-team, single-elimination tournament annually crowns the NCAA Division I men’s college basketball national champion.
The event is aptly named, considering it features 67 frenetic games over a 19-day period. The NCAA reveals participating schools, seeding, and brackets on “Selection Sunday.”
The annual college basketball rite of spring is sports betting’s most prolific multi-day event. Below, you’ll find the current betting odds for the favorites to win the NCAA tournament, along with key tournament details and betting strategy to help you during the month-long madness.
The first 32 teams to gain entry into the tournament do so automatically by winning their conferences. All remaining 36 slots are filled by “at-large” teams. A 10-member selection committee consisting of athletic directors and conference commissioners undergoes an arduous and multi-layered process to determine the 36 at-large teams and finalize seeding and brackets.
The committee will again employ the NCAA Evaluation Tool (NET) as its primary sorting method for determining at-large entrants. NET replaces the RPI (Rating Percentage Index) utilized since 1981.
The NET takes into account the following metrics:
- Game results
- Strength of schedule
- Game location
- Scoring margin
- Offensive and defensive efficiency
- Quality of wins and losses
The NCAA has a detailed, step-by-step breakdown of seeding and bracket protocol on this page of its website.
