March Madness Betting Trends, Stats, Notes: Action Network Betting Primer
Before we start — it’s important to know this is a live running article. Content, matchups, odds, trends, and systems will all be added to the piece through the end of the first round of action on Friday, March 20 (check the updated as-of date below!).
We’re here to answer tourney questions, dish out stats and facts, talk futures, the bracket, coaches, Cinderellas and more. Welcome to the March Madness edition of Action Network’s betting primer.
All data, stats and trends are updated as of Monday, March 16, 8 a.m. ET.
The undefeated Huskies. Connecticut enters the 2026 NCAA Tournament on a 14-game ATS win streak in the Big Dance, the longest ATS win streak for any team in the seeding era — including 14-0 ATS in total over the last three NCAA Tournaments.
Most Consecutive NCAA Tournament ATS Covers Since 1979
- UConn 14 (2023-25)
- West Virginia 12 (1998-08)
- Villanova 11 (1985-88)
- Dan Hurley is 17-3 ATS (85%) in the NCAA Tournament as a head coach, which is the highest ATS win percentage for a coach (min. 10 games) in the seeding era since 1979.
- Dating back to the 2008-09 NCAA Tournament, the Huskies are 30-6 ATS in the dance, including 11-0 ATS as a favorite of seven points or more in the tournament since that 2009 date, with Hurley being 8-0 ATS in the NCAA Tournament as a favorite of 7+ points.
Since seeding began in 1978, every NCAA champion to play in a conference tournament won at least one game in that appetizer for March Madness. In that span, eight champions never actually had a conference tournament (’97 ARI, ’95 UCLA, ’89 MICH, ’87 IU, ’81 IU, ’79 MSU, ’78 UK, ’77 MARQ).
If this trend holds true, here are some of the candidates this eliminates this year: UNC, Miami (OH), Villanova, Michigan State, Nebraska, Illinois, Texas Tech, Alabama and Saint Mary’s.
Round of 64 games can go the other way — teams coming off an outright win entering the Round of 64 facing a team who lost their last game are just 31-113 (21.5%) straight up since 2016-17 and they went 3-16 straight-up last year. Here are those teams: COMING SOON!
Hit your free throws kids. To say it simply, good free throw shooting teams have historically had covering success in the tournament. Teams averaging 75%+ from the stripe have been cashing at a 56.5% rate with a 9% ROI since 2008 NCAA Tournament.
Raise it to 76%, it’s 16.1% ROI and at 77%, it’s been historically a 21.8% ROI. Teams shooting 77% or higher on the year are 97-56-2 ATS (63.4%) in the NCAA Tournament in this span.
Where free-throw shooting is most important is in tight games. At 77%+, when the spread is six or less, that good free-throw team is 60-34 ATS (64%), with a spread of four or less, they are 39-19 ATS (67.2%), covering the spread by 4.1 points per game.
Round of 64 matches: COMING SOON!
Don’t always believe what you just saw. Since the 2013 NCAA Tournament, teams to win by 20+ points in the Round of 64 are 25-44-1 ATS (36.2%) in the Round of 32 when their opponent won by less than 20 points in the Round of 64.
According to our Bet Labs database, after a team pulls off a double-digit point spread upset in the NCAA Tournament, they are 4-20 straight up and 8-16 against the spread in the next round, dating back to 2005.
After pulling the upset in the previous round, teams that get the majority ticket count ATS in their next game are 1-16 SU and 4-13 ATS in this span, with the only win coming from Florida Gulf Coast back in 2013.
How has Cinderella performed lately? In the NIL era, not so good.
13 to 16 seeds in the Round of 64 are 6-58 (9.4%) straight up and 25-39 (39%) against the spread since 2021, with a moneyline bettor losing 13.7% ROI and an ATS bettor 25.3%. The ATS bettor is failing to cover by 1.86 PPG.
- Between 2016-20: 8-56 SU, 33-29 ATS (+1.26 cover margin)
- Between 2015-15: 9-55 SU, 35-28-1 ATS (+0.56 cover margin)
Favorites of eight points or more went 21-0 SU in the NCAA Tournament last year — tied for the second-most SU wins without a loss for 8+ pt favorites in history behind 22-0 SU mark in 2007. Those 8+ point favorites are 57-5 SU over the last three NCAA Tournaments, including 19-0 after the Round of 64.
Favorites went 14-1 SU in the Sweet 16 or later in last year’s tournament, the best record for any season in the seeding era.
In 2024, the public had its best March Madness in over two decades. Teams with more than 50% of the spread bets (or tickets) went 45-21 ATS (68%) with a $100 bettor up $2,003 for a 30.4% ROI.
2025 saw a reversal to more of a normal mark. The public went 27-38 ATS (42%) with a $100 bettor losing $1,326 for a -20.4% ROI. Overall, the betting public has been .500 ATS or below in eight of the previous 13 seasons.
Since 2005, only 13 different teams have closed with at least 80% of the spread bets in the NCAA Tournament. Those 13 teams are 2-11 ATS. When you lower it to 75%+, those sides are 31-44-2 ATS in March Madness.
Since PASPA was repealed in May of 2018, unders are 222-175-4 (55.9%) in the NCAA Tournament. Unders are .500 or better in each of the six tournaments in that span. But this is about first-half unders.
Since the 2012 NCAA Tournament, games played at 1 p.m. ET or earlier in March Madness have seen the under go 67-44-3 (60.4%) in the first half with a +14.5% ROI. Since the 2018 tournament, this is 32-26 to the first half under.
First-half unders in the NCAA Tournament overall are 254-207-7 (55.1%) since 2018. When those games are played in the Round of 64, they are 123-97-3 (55.9%) to the under.
Since 2016, the Mountain West conference is 13-26 ATS (-$1,414 on $100 bet, -36% ROI) in the NCAA Tournament. That is the lowest ROI of any major conference and the least profitable of any conference against the spread.
In the last 17 tournaments dating back to the start of the 2007 season, the Mountain West has been above .500 ATS in a single tournament once, back in 2018.
Mountain West teams seeded ninth or worse are just 9-29-2 ATS in the NCAA Tournament, including going 5-35 SU in those games.
Since Arizona won the national title in 1997, no team west of Texas has won it all.
Since the 2000 NCAA Tournament, the Big Sky Conference has had its issues in the Big Dance. Overall, the Big Sky is 1-25 SU and 7-17-2 ATS in the NCAA Tournament, with the only SU win coming from Montana back in 2006, with the conference losing 19 consecutive games in the tourney.
Since the 2006-07 NCAA Tournament, the Big Sky is 3-14-1 ATS in the NCAA Tournament.
Since the 2011 NCAA Tournament, the Big Ten is 59-34-3 ATS in the Round of 64, the best mark of any conference.
The Big Ten has gone eight straight tournaments .500 ATS or better in the Round of 64, including .500 ATS or better in 13 of the last 14 tournaments.
Let’s take a look at the best and worst conferences against the spread in the NCAA Tournament over the last five tournaments…
Conferences ATS in NCAA Tournament| The Best | The Worst | ||
| 1. | Big East: 37-21 ATS | Mountain West: 10-21 ATS | |
| 2. | ACC: 40-28 ATS | SEC: 43-50 ATS | |

Let’s take a look at some NCAA Tournament systems. Click each system for matches, bets and detailed profitability charts.
Notes: This system targets undervalued teams coming off a good defensive performance. The system is .500 ATS or better in the last 7 NCAA Tournaments.
Current matches: USF, Siena
Notes: The old notion, “Fade The Public.” This system targets under-bet teams in high-bet games. For this, we are using 1.1X daily bet average. If you have Bet Labs, increase that DB-AVG for smaller sample, higher ROI matches.
Current matches: Check updated betting lines
Notes: Free-throw shooting in the tournament is key. This system targets the better shooting teams vs. the teams shooting under 75%.

Click here to return to the table of contents.Notes: In the NCAA Tournament, it’s been all about first-half Unders. Since 2017, 1H unders in First Four and Round of 64 are 137-111-3 (55.2%) and the unders are .500 or better in every round except for the Round of 32.
Look for first-half Unders in the NCAA Tournament between slower-paced teams.
Current matches: COMING SOON!
Speaking of pace. When a higher-paced team for the season faces a lower-paced team during the tournament, historically, the slower-paced team has had the advantage covering the spread, especially in the early rounds.
Current matches: COMING SOON!
Click here to return to the table of contents.When two teams that are both over .500 to the over during their season entering the NCAA Tournament, meet, the total being inflated and the under hitting has been a good strategy.
Current matches: SMU/Miami (OH), Villanova-Utah State
Teams to win by 20+ points in the Round of 64 are 82-33 straight up, but just 49-64-2 ATS in the Round of 32 when their opponent won by less than 20 points in the Round of 64 since 2005.
Teams entering the NCAA Tournament off a loss of 20+ points are 28-14-1 ATS in the Round of 64 since 2005.
Current matches: COMING SOON!
Click here to return to the table of contents.Don’t turn over the ball. Tourney teams that average a low number of turnovers have success as underdogs in the first half of the Round of 64.
1H dogs averaging 11 TO or fewer on the year are 88-61-2 1H ATS (58.2%) in the Round of 64 since 2011, finishing above .500 ATS in nine straight NCAA Tournaments.

Click here to return to the table of contents.When looking strictly at game-to-game spread betting percentages from our Action Labs software — which is available for every game across 10+ sports — here are some notes about public betting patterns:
How do popular underdogs perform in the NCAA Tournament?
In the Round of 64, underdogs receiving the majority of the ticket count are basically .500 ATS at 87-90-2 ATS since 2005, but in the Round of 32, they are 39-54-1 ATS, the worst mark of any round in the tourney.
How has the public performed overall in March Madness?
Two years ago, the public had their best March Madness by far. Teams with more than 50% of the spread bets or tickets went 45-21 ATS (68%) in 2024. A $100 bettor was up $2,003 for a 30.4% ROI. 2025 saw a reversal to more of a normal mark. The public went 27-38 ATS (42%) with a $100 bettor losing $1,326 for a -20.4% ROI. Overall, the betting public has been .500 ATS or below in eight of the previous 13 seasons.
What have we learned about public betting and over/unders?
The public tends to do a better job at accurately predicting Unders in the NCAA Tournament than Overs. Here are the public betting results for Overs and Unders in the past seven tournaments (since 2017-18):
Should you avoid massive public sides?
Since 2005, only 13 different teams have closed with at least 80% of the spread bets in the NCAA Tournament. Those 13 teams are 2-11 ATS. When you lower it to 75%+, those sides are 31-44-2 ATS in March Madness.

Click here to return to the table of contents.Favorites have dominated the NCAA Tournament recently. In the last two tournaments, favorites are 76-58 ATS (56.7%), covering the spread by 1.5 PPG, with a $100 bettor up 8.6% ROI at +$1,148 — the best two-year stretch for favorites ATS since 2008-09.
In that span, favorites of 6+ pts are 46-25 ATS (+$1,712, +24% ROI) and favorites of 8+ pts are 32-14 ATS (+$1,520, +33% ROI).
Let’s Talk Elevation
Using Bet Labs, we’ve identified 16 schools playing at the highest elevation in the country during the season. Since 2005, those teams are 32-69-1 ATS (32%) in the NCAA Tournament. They’ve finished above .500 ATS as a group of schools just once since 2005.
Current matches: Utah State
Since the 2013 NCAA Tournament, we’ve had 25 teams play in the Round of 64 on 3 total days rest or less as a favorite and face a team on 4+ days rest on the other side.
An example would be Wisconsin vs. Montana in 2024. The Badgers lost in the Big Ten title game on Sunday and played Montana on Thursday. Montana last played eight days prior on Wednesday.
Those 25 teams are 23-2 SU and 16-8-1 ATS in that span — the good team, without a massive layoff.
Current matches: COMING SOON!
NCAA Tournament teams with a big spread tend to go over the total, the lower the over/under in the game is.
Since the 2014 tourney, favorites of 15+ pts with a total of…
150 or less: 38-25-1 to over (15.5% ROI)
140 or less: 27-12 to over (33.1% ROI)
135 or less: 22-8 to over (41.2% ROI)
Current matches: Houston/Idaho, Duke/Siena, UConn/Furman — more as well for different filter levels.
We’ll start with the 8 vs. 9 battle. 8-seeds are 77-83 SU, 72-84-4 ATS vs. 9-seeds in the Round 64 since 1985. It’s the Round of 32 where you see the difference.
➤Round of 32 Results: 8-seeds in R32: 19-75 SU | 9-seeds in R32: 10-81 SU.
Click here to return to the table of contents.Of teams seeded 10th or higher in the NCAA Tournament, the 11 seed is the only one above .500 on the moneyline since 2010 in the Round of 64. 11 seeds have been profitable on the moneyline in the Round of 64 in 14 of the last 19 tournaments.
Double The Fun
One double-digit seed has reached every Sweet 16 since 2008, and at least one 10-seed has at least one win vs. a seven-seed in 30the of last 31 NCAA Tournaments, including 43 of 46 tournaments since seeding began.
We’ve had exactly one in each of the last three tournaments:
2025: Arkansas (10)
2024: NC State (11)
2023: Princeton (15)
Looking for a way to identify a Round of 64 double-digit seed to pull the upset? Let’s look at seeds 11 through 16 since 2005.
Pace of play is an interesting start. A slower-paced team — bottom 3rd in the country, 67 possessions or less — wins just 23% of R64 games, -13% ROI SU.
Over that pace mark, they win 24.2% of games, for a +16% ROI.
(The team’s pace for the current season. Pace is measured as possessions per 48 minutes in the NBA, possessions per 40 minutes in NCAAB. The higher the number, the faster the team’s tempo is.)
Current matches: COMING SOON!
Round of 64: Florida (-28.5) beat Norfolk State, 95-69
Round of 32: Florida (-9.5) beat UConn, 77-75
Prior to the Florida Gators last year, the only other team since 1985 to start an NCAA Tournament 0-2 ATS and go on to win it all was Arizona back in 1997.

➤ The “First Four” began back in 2011. There have been 112 “First Four” teams and 56 winners.
➤ Entering 2026, 28 of those 56 winners were 16-seeds, while 28 were non-16-seeds.
➤ 27 of those 28 teams seeded 16th lost in the Round of 64, with Fairleigh Dickinson beating Purdue as the lone exception.

Heading into March Madness, here are the biggest upsets in the tournament and the betting records set throughout the years.
What is the biggest NCAA Tournament favorite?
In the seeding era, 1999 Duke takes the cake when it was a 46-point favorite against Florida A&M. The Blue Devils beat the Rattlers 99-58, failing to cover the lofty 46-point spread by five points.
Only three teams have closed as a favorite of 35 points or more dating back to 1978, and none since 1999 (all listed below). But recently, we’ve seen some big favorites in the NCAA Tournament. Since 2005, we’ve had eight favorites of 28+ points in the NCAA Tournament — four came last year in 2025.
Biggest Favorites in NCAA Tournament Since 1978:
| Team | Matchup (ET) | Year/Result |

What are the highest & lowest totals in the NCAA Tournament?
The last two years of the NCAA Tournament have changed the game when it comes to totals — and it’s all Alabama’s fault.
Since the 1996 tournament, we’ve had five games with a total of 170+, and all five included the Crimson Tide over the last two seasons (2024 and 2025 tournaments):
In Alabama’s nine NCAA Tournament games in 2024 and 2025, they went 5-4 to the over, but they are 5-2 to the over with a total of 162 or higher and 4-2 to the over at 165 or higher. Here are the highest totals in the last 30 years of the NCAA Tournament:
Prior to Alabama’s 2024 and 2025 campaigns, we had only seen two totals since 1995 reach above the 170 mark in the NCAA Tournament, and those came all the way back in 1995, both with Texas involved.
➤In the 1995 tourney, the Texas Longhorns, behind coach Tommy Penders, were averaging almost 93 points per game and had back-to-back games with a total above 170. They faced Oregon in the Round of 64 and won, then the total got a little higher when they faced an even higher-scoring team in Maryland, a game in which the Longhorns lost by 14. Both games went under the total.
When it comes to the lowest totals, we’ve only seen one close below 110, and that came in 1996 between Princeton and Mississippi State. If we lift the floor a bit, we’ve only seen two totals close at 115 or lower since the 2010 NCAA Tournament — Northern Iowa/Wyoming in 2015 (110.5) and Cal/South Florida in 2012 (114).
➤The story of this over/under tale is Princeton’s defense, which was No. 1 in the country in 1995-96 and allowed under 52 points per game. As a 13-seed in the Round of 64, the Tigers beat 4-seed UCLA, 43-41, and held the Bruins to 38.5% shooting (Princeton shot 37% and won). Then, in the Round of 32, the total closed at 108 vs. Mississippi State, which beat Princeton, 63-41, barely staying under the total.
In the new era of college basketball from a betting perspective, since PASPA was repealed in May of 2018, unders are 222-175-4 (55.9%) in the NCAA Tournament. Unders are .500 or better in each of the six tournaments in that span:
In that span, we’ve had four totals below 120 points, and they all came back in the 2019 NCAA Tournament:
The lowest total since then was Virginia and Colorado State in 2024 and San Diego State and Creighton in 2022, both with a total of 121.

Worst betting losses in the NCAA Tournament
➤Since 1978, Kansas has had the most losses by any school as a double-digit favorite (6), but none since 2011. Arizona and Duke are second on that list with four losses as double-digit favorites each — Arizona’s last loss came in 2023, while Duke’s was back in 2014.
