March Madness Odds: Weekly NCAA Tournament Updates

Let the madness begin. The three-week long NCAA men’s basketball tournament, affectionately known as March Madness, begins with the First Four on March 17 and concludes with the national championship game at Lucas Oil Stadium in Indianapolis, IN on April 6. 

A total of 68 teams will vie for the title with Duke, Michigan and Arizona among the favorites in the opening NCAA Tournament odds. The defending champion Florida Gators closed the regular season on an 11-game winning streak claiming the regular season SEC title and shortening their championship odds.

March Madness 2026 Schedule & Locations

March Madness officially begins with the “First Four.” When the current 68-team format was adopted in 2011 it necessitated the “First Four” games, used to determine the clubs included in the field of 64. The “First Four” takes place Tuesday and Wednesday before the first round games and is contested at UD Arena in Dayton, OH. Here are the dates and locations for March Madness 2026.

There have been some memorable moments over the history of the NCAA Tournament with huge upsets, buzzer-beating shots and extraordinary performances, all leading to the creation of the nickname March Madness,

Latest NCAA Tournament Odds This Week

Before we get to March Madness the field of 68 teams has to be determined. Teams can automatically earn a spot in the dance by winning their conference tournament championship or they can be selected as an at-large team. There are 31 conference champions and 37 at-large picks.

For teams on the NCAA Tournament bubble, winning their conference or having a deep run in the tournament improves their chances making college basketball tournament betting exciting. The best teams don’t always win their conference tournament. Although it worked out for Florida last year winning the SEC tournament as the No. 2 seed then going on to claim the national championship. 

Florida closed the regular season with 11 consecutive wins claiming the SEC title at 16-2. They have just one setback since Jan. 3 and are a huge negative odds favorite to win the SEC tournament. Even if the Gators don’t win they are a likely No. 1 seed in the NCAA Tournament.

The Big 12 is the only conference with 2 of the top 5 teams on the early NCAA Tournament betting board. And at least 2 other teams are considered threats to cut down the nets in April. Arizona won the regular season winning 16 of 18 games with the top 5 teams all winning at least 12 Big 12 games and 22 games overall. No conference is stronger at the top making the Big 12 a favorite to produce the national champion.

March Madness Championship Odds

Another reason for the popularity of March Madness are the betting opportunities it creates. College basketball tournament betting rivals that of the Super Bowl. And with 32 games spread over the first 2 rounds it’s a smorgasbord for those wanting to wager.  

The tournament field is still being decided at the time of this writing, but several teams are guaranteed spots due to their abundance of talent and success this season. Duke closed the regular season as the No. 1 ranked team in the country boasting a 29-2 record and the likely national player of the year in Cameron Boozer. 

Michigan blasted through a tough Big Ten schedule winning all but one of its 20 conference games and going 29-2 overall. Their only loss since early January was to Duke, 68-63, on Feb. 21 yet the Wolverines opened with the shortest March Madness championship odds. Michigan boasts an experienced roster and is the only team ranked among the top 4 in offense and defensive efficiency.

Arizona is another title threat thanks to a balanced roster that has arguably the best frontcourt in the nation led by Koa Peat and Mo Krivas. The Cats won their first 23 games and have marquee wins over Florida, UConn, Houston and Kansas. 

TEAM ODDS PROBABILITY

Top Favorites to Win It All

Michigan – You don’t often see teams with four upperclassmen in the starting lineup, but the experience has helped Michigan’s rise to the top. Big Ten player of the year candidate Yaxel Lendeborg leads a physical frontcourt that helps UM rank 5th in blocked shots and 3rd in defensive efficiency.

Arizona – Not only do the Cats have a strong frontcourt, they’ve gotten steady play from the backcourt tandem of Brayden Burries, who leads the team with 16.2 points per game, and Jaden Bradley, who is second with 13.3 points. They rank inside the top 10 in offensive and defensive efficiency and worked through a demanding schedule.

Duke – With Cam Boozer tossing in nearly 23 points a game the Dookies can score. They also defend better than any team in the country. Duke allows just 62.5 points a game and is No. 1 in defensive efficiency. They beat Michigan as part of a season closing 8-game winning streak and finished 29-2.

Dark Horses and Sleeper Picks

BYU – The Cougars were a top 10 team until January when they slumped, dropping 8 of their last 12 regular season games. And losing Richie Saunders to an ACL hurt their odds. Still, they boast an offense that averages almost 84 points. A likely lottery pick, AJ Dybantsa averages 25.3 points and 6.7 rebounds.

Arkansas – The Hogs might be better than last year’s Sweet 16 team. They tied for 2nd in the rugged SEC winning 23 games and boast a high tempo offense that’s 3rd in the country in scoring. Their style of play leads to scoring but Arkansas also ranks among the top 5 in the SEC in defensive efficiency.

Upcoming Games & Betting Preview

Get ready to fill out your bracket because the NCAA Tournament lineup will be announced on Sunday, March 15. The Madness officially begins with the First Four on Tuesday, March 17 and Wednesday, March 18. Then the fun really starts with 32 first round games split over Thursday, March 19 and Friday, March 20. 

While we’ve witnessed major upsets over the years like a No. 16 seed beating a No. 1 twice since 2018, the higher seeded times typically rise to the top. Over the last 40 tournaments a team seeded in the top 3 has won the title 35 times. No team seeded lower than 8th has ever won.

Betting Strategies by Tournament Round

Successful wagers on the NCAA Tournament require bettors to adjust their strategy by rounds. Most major upsets occur in the opening rounds with more predictable matchups by the Final Four.

One trend to note is that over the last three tournaments the UNDER has cashed nearly 60 percent of the time in the first round. There’s also something about the 5-12 matchup. Since 2012 the 12th seed is 27-20-1 ATS.

Moving forward injuries are an issue that can affect the college basketball betting lines and how to wager on games. Oftentimes teams that roll in the first round carry over that momentum into the second round.

Historically No. 1 seeds have had a lot of success in the Sweet 16. The second week of the tournament also brings about different travel schedules and venues with the UNDER on the total frequently paying out.

Key Factors That Impact NCAA Tournament Odds

There are several factors that can mess with the NCAA Tournament odds with none more important than a team’s health. An injury to a key player can make all the difference. Outside of that, analytics have taken over with offensive and defensive efficiency a measuring stick. Over the past 23 tournaments all but one champion was ranked among the top 20 for both metrics.

According to most experts there are four areas that are the biggest predictors of game results and point spread. Turnovers have the biggest impact with defensive rebounding, assists and free throw attempts the other major areas to play close attention to.

Talent alone can win a lot of games, but when it comes to the later rounds and teams are closer in that regard, coaching and experience can be a deciding factor. Teams with veteran leaders and successful coaches tend to outperform their seed expectations.
