These three teams have separated themselves after strong performances in the early rounds, with Michigan benefiting from dominant wins to leapfrog others on the board.

Houston represents the next tier at +700, providing solid value as a deeper contender with strong defense and experience. Illinois and Purdue both hover around +1300, suggesting they could make deep runs if their offenses click in key matchups. Iowa State at +1500 remains dangerous with its balanced play, while UConn at +2500 reflects some regression from preseason expectations but still carries a championship pedigree.

2026 March Madness Odds Betting Tips

Purdue-Texas

Purdue has looked dominant, covering easily in prior rounds with strong interior play and Trey Kaufman-Renn providing consistent scoring.

Sharps lean toward Purdue covering, as the Boilermakers are 18-8 ATS as favorites under Matt Painter in the tournament, and Texas struggles defensively against physical Big Ten-style teams.

The total leans under in a regional semifinal, with both teams capable of slowing the pace.

Nebraska-Iowa

Nebraska's defense has been stout, suffocating opponents and forcing turnovers, while Iowa's surprise run featured a gritty win over a top seed

But the Hawkeyes lack depth against a more balanced Cornhuskers squad.

Nebraska covers here, and the low total suits their grind-it-out approach, favoring the under.

Arizona-Arkansas

Arizona has handled business efficiently despite some close calls with elite guard play and rim protection.

Arkansas brings athleticism and scoring, but the Wildcats' depth and defensive versatility should keep this from getting too close.

Arizona covers comfortably, while the high total has value on the over given Arkansas's up-tempo style, which forces Arizona into more possessions.

Illinois-Houston

Houston's elite perimeter D is clashing against Illinois' balanced attack.

Houston covers narrowly as favorites in college basketball betting, with home-court feel at Toyota Center and the ability to force misses and turnovers.
