The first weekend of the 2026 NCAA Tournament has officially come to a close, leaving us with a Sweet 16 field that is dominated by power conferences. After a Sunday that saw the defending champion and top-seeded Florida Gators fall to the Iowa Hawkeyes, the bracket has shifted significantly.
We are left with a field featuring six teams from the Big Ten and four from the SEC, while mid-majors have been entirely shut out of the second weekend. Interestingly, the Texas Longhorns stand alone as the last double-digit seed remaining, providing the only semblance of a Cinderella story in what has otherwise been a very chalky tournament.
As we move into the regional semifinals, the landscape for betting on the Sweet 16 is heating up. Favorites have controlled the board so far, leading 39-9 straight up and 27-19-2 against the spread. However, with several days of rest and preparation, the current March Madness odds offer some intriguing opportunities for those looking to find value.
Below is a breakdown of the upcoming matchups for Thursday and Friday.
Texas vs. Purdue
- Texas (#11) +7.5 (-110) | ML +275 | O 149.5 (-110)
- Purdue (#2) -7.5 (-110) | ML -350 | U 149.5 (-110)
The Texas Longhorns have been the ultimate survivors of this tournament, beginning their journey in the First Four and now standing as the lone double-digit seed in the Sweet 16. After taking down Gonzaga in the second round, they face a massive test against Matt Painter and the Purdue Boilermakers. Purdue has looked dominant, ranking among the top offensive units in the country.
While Texas has the momentum of a team that refuses to quit, the height and efficiency of the Boilermakers make them a 7.5 point favorite at college basketball sportsbooks. Historically, number two seeds have faced pressure in this spot, but Purdue’s ability to control the paint has kept bettors confident in the chalk.
Iowa vs. Nebraska
- Iowa (#9) +2.5 (-110) | ML +120 | O 134.5 (-110)
- Nebraska (#4) -2.5 (-110) | ML -140 | U 134.5 (-110)
In an all-Big Ten clash, the Iowa Hawkeyes look to continue their miracle run after knocking off the number one seed, Florida. Nebraska enters as a narrow 2.5 point favorite, having reached the Sweet 16 for the first time in school history. This game is expected to be a defensive battle, as evidenced by the relatively low total of 134.5.
Iowa has shown they can win ugly by slowing down the tempo, while Nebraska relies on a balanced attack that has carried them through a record-breaking season. With the familiarity between these two programs, expect a tight, physical contest that comes down to the final possessions.
Arkansas vs. Arizona
- Arkansas (#4) +8.0 (-105) | ML +300 | O 167.0 (-110)
- Arizona (#1) -8.0 (-115) | ML -400 | U 167.0 (-110)
Arizona remains a heavy favorite to win the West Region, and the oddsmakers have reflected that with an 8 point spread against Arkansas. The Razorbacks, champions of the SEC tournament, are high-scoring and athletic, but they face an Arizona squad that leads the nation in several offensive metrics.
The total of 167.0 is the highest on the board for the Sweet 16, suggesting a track meet is in store. Arkansas will need to find a way to disrupt the Wildcats’ flow, but Arizona has been a covering machine when favored by single digits this season.
Illinois vs. Houston
- Illinois (#3) +3.0 (-115) | ML +130 | O 140.0 (-110)
- Houston (#2) -3.0 (-105) | ML -150 | U 140.0 (-110)
This is arguably the most anticipated matchup of the Thursday slate. Houston’s elite defense faces off against an Illinois offense that KenPom ranks near the top of the country. The 3 point spread indicates a toss-up, and early money has fluctuated between the two sides.
Houston thrives on creating turnovers and winning the rebounding battle, whereas Illinois relies on high-percentage shooting and individual playmaking. If the Fighting Illini can handle the Cougars’ physical pressure, they are a live underdog to reach the Elite Eight.
St. John’s vs. Duke
- St. John’s (#5) +7.0 (-110) | ML +250 | O 143.0 (-110)
- Duke (#1) -7.0 (-110) | ML -300 | U 143.0 (-110)
Rick Pitino has St. John’s back in the national spotlight, but they run into a Duke team that has been the tournament favorite since Selection Sunday. The Blue Devils are 7 point favorites, boasting a deep roster of future pros. St. John’s is known for its frantic pace and aggressive defense, which could bother Duke’s young backcourt.
However, the Blue Devils have been incredibly efficient on neutral courts this year. Bettors are watching this line closely to see if the Red Storm’s “peaking at the right time” narrative can overcome the raw talent of the number one seed.
Alabama vs. Michigan
- Alabama (#4) +10.0 (-110) | ML +400 | O 174.0 (-110)
- Michigan (#1) -10.0 (-110) | ML -575 | U 174.0 (-110)
The largest spread in the Sweet 16 belongs to Michigan, which is are double-digit favorite over Alabama. The Wolverines have been a juggernaut, scoring 101 and 95 points in their first two tournament games. Alabama also prefers a high-octane style, which explains the massive 174.0 total.
While the Crimson Tide has the scoring punch to keep up for a half, Michigan’s defensive discipline and depth make it a daunting opponent. Historically, number one seeds favored by 10 or more have a high win rate, but can struggle to cover if the underdog hits a hot streak from three-point range.
Michigan State vs. Connecticut
- Michigan State (#3) +1.0 (-110) | ML -105 | O 136.5 (-110)
- Connecticut (#2) -1.0 (-110) | ML -115 | U 136.5 (-110)
This is essentially a “pick-em” game between two programs with a championship pedigree. UConn enters on a historic 14-game against-the-spread winning streak in the NCAA Tournament, the longest in the seeding era. Tom Izzo’s Michigan State squad looks to be the team that finally breaks that streak.
Both teams play physical, deliberate basketball, making the 136.5 total an attractive target for those who expect a grind-it-out affair. With the spread at just 1 point, this game will likely be decided by whoever executes better in the final two minutes.
Tennessee vs. Iowa State
- Tennessee (#6) +4.0 (-110) | ML +150 | O 138.5 (-110)
- Iowa State (#2) -4.0 (-110) | ML -175 | U 138.5 (-110)
The final game of the Sweet 16 features two of the most disciplined teams in the country. Iowa State is a 4 point favorite, backed by a defense that ranks in the top five nationally. Tennessee has defied its number six seed by playing elite basketball over the last two weeks, including an impressive win over Virginia.
This matchup is a classic case of strength versus strength, with Iowa State’s pressure defense meeting Tennessee’s patient offensive sets. The under has been a popular play in recent Iowa State games, and with the stakes this high, a low-scoring battle is expected.
