  • Opening point spread: Arizona -1.5
  • Opening moneyline: Arizona -115/Michigan -105
  • Opening total: Over/Under 156.5 points scored
  • Time: 8:49 p.m. ET Saturday (TBS)

LATEST UPDATE: Arizona is -1.5 (+110) at BetMGM, 50 minutes or so before tipoff. On Sunday, Arizona opened -1.5 (even), but that didn't last long, flipping to Michigan -1.5 (-105) within minutes.

The Wolverines remained at various iterations of -1.5 all week. Then early this afternoon, the line flipped back and forth a couple times, from Michigan -1.5 to Arizona -1.5.

"We need Michigan for a round of drinks. Money is pretty split down the middle, on the spread and the moneyline," BetMGM trading manager Tristan Davis said.

The total is at 157.5, moving off 156.5 (Over -125) earlier this evening. The number opened at 156.5 (Over -115) and toggled to 157.5 multiple times this week.

FIFTH UPDATE: As of 1:30 p.m. ET Saturday, seven-plus hours before tipoff, Station Sports has Michigan a 1.5-point favorite in March Madness Final Four odds. The line opened at Arizona -1 on Sunday, but the favorite quickly flipped.

"The early push was on Michigan as we went from +1 to -1.5. Ticket count is evenly split at 50/50," Station sportsbook director Chuck Esposito said, while noting championship futures somewhat play into tonight's need. "Overall, Michigan and Illinois are our best case.

"But there's no liability on any of the four teams."

Station's total is at 157.5, but there's no notable need yet, Esposito said.

FOURTH UPDATE: While some shops opened Arizona as slim chalk, theScore Bet opened Michigan -1.5 (-105). The juice then adjusted a couple times at that number (-115/-110/even), but the Wolverines have been steady at -1.5 (-105) since Tuesday morning.

As might be expected of two No. 1 seeds, action is very much two-way on this matchup, as of 1:30 p.m. ET Friday. Spread tickets are running dead even, with 55% of spread money on short 'dog Arizona. On the moneyline, 54% of bets/56% of dollars are on the Wildcats.

"The money slightly favors Arizona. But it's been mostly balanced, two-way traffic for this battle between 1 seeds on Saturday night," theScore Bet sportsbook VP Adam Landeka said.

The total was pinned to 157.5 at theScore Bet all week, then went to 158.5 on Friday morning. The Over is attracting 64% of early bets/55% of early money.

THIRD UPDATE: Borgata Sports, a BetMGM shop in Atlantic City, has Michigan a 1.5-point favorite in March Madness Sweet 16 odds, as of 1:30 p.m. ET Wednesday. That's right where it opened on Sunday night.

"Michigan moneyline has been very popular early. Nothing that would be profiled as sharp, but the public certainly seems to be favoring Michigan upon opening the number," Borgata sportsbook director Tom Gable said. "We’ve since seen some decent support for Arizona.

"Much like the Illinois-UConn game, there isn’t a big decision on this one at the moment."

Championship futures could be the deciding factor in Borgata's need on Saturday night.

"From a national title perspective, Michigan is actually our best result of the four teams remaining, due to their national title odds being shortened so early in the season.  We are a small loser to Arizona in the futures," Gable said.

Borgata's total is up to 157.5 from a 156.5 opener.

SECOND UPDATE: Michigan is -1.5 (-112) as of 8 p.m. ET Monday, 24 hours after hitting DraftKings' March Madness Final Four odds as a 1.5-point underdog. That lasted all of 30 minutes before the number flipped Wolverines -1.5 (+102), followed by a couple of juice adjustments.

That said, early spread play is two-way, with 52% of bets/56 of money on Michigan. Early moneyline action leans toward Arizona, at 60% of bets/63% of money.

DK's total is at 157.5, going there shortly after opening at 156.5 onSunday night. The Over is drawing 71% of early bets/80% of early money.

OPENING ODDS UPDATE: No. 1 Arizona (36-2 SU/24-14 ATS) trailed No. 2 Purdue 38-31 at halftime Saturday night. But the Wildcats owned the second half and rolled to a 79-64 victory laying 5.5 points in the West Region final.

Arizona is on a 13-0 SU tear, going 9-4 ATS in that stretch.

On the flip side, No. 1 Michigan (35-3 SU/18-20 ATS) had no issues disposing of No. 6 Tennessee in Sunday's Midwest Region final. The Wolverines led 48-26 at halftime and expanded that lead in the second half in a 95-62 wipeout as 8.5-point favorites.

Michigan has scored 90 or more points in all four NCAA Tournament games and covered in the last three, after an 0-6 ATS slide. Michigan is currently the favorite in March Madness futures odds, narrowly ahead of Arizona.

Moments after Michigan's win, DraftKings opened Arizona -1.5 (-105) in March Madness Final Four odds. Within 30 minutes, at 5:45 p.m. ET Sunday, the line jumped the fence to Michigan -1.5 (-102).

As of 8 p.m. ET Sunday, Michigan is netting 58% of early spread bets/63% of early spread dollars. On the moneyline, tickets are dead even and 59% of cash is on the Wolverines.

DK's total is up a point to 157.5, with 81% of bets/87% of cash on the Over in the early going.

LATEST UPDATE: With 45 minutes until tipoff, Illinois is -1.5 (-115) in BetMGM's 2026 Final Four odds. The Fighting Illini opened -2.5 (-105), toggled to various iterations of -1.5 early on and were stuck at -1.5 (-115) since Tuesday.

But in the final hour before tip, the Illini briefly went to -2.5 (-102), before going back to -1.5 (-115).

"We are split down the middle on moneyline parlays. But on straight bets at the 1.5 spread, it's fairly lopsided for Illinois," BetMGM trading manager Tristan Davis said.

So Davis said the book might not mind a UConn win tonight. However, a UConn loss eliminates the only liability in BetMGM's championship futures market.

"It helps. But let's see what this game does, and we will worry about Monday later tonight," he said.

The total is at 139.5 (Under -115), and it's been at some iteration of 139.5 most of the week, after a couple short trips to 138.5. Davis said BetMGM prefers the Under, per usual.

FIFTH UPDATE: Station Sports, which runs a host of sportsbooks around Las Vegas, has Illinois as 2-point chalk in Final Four odds, as of 1:30 p.m. ET Saturday. That's down a tick from the opener of Fighting Illini -2.5.

"The early push was clearly on UConn. But ticket count is split," Station sportsbook director Chuck Esposito said. "At this point, Illinois winning is the best-case scenario. There's not a huge decision on either game yet."

Station's total is at 139.5, with Esposito saying the decision isn't yet notable, though that could change by tipoff.

FOURTH UPDATE: As of 1:30 p.m. ET Friday, theScore Bet has Illinois -1.5 (-115), a slight adjustment from this morning's -1.5 (-120). Both those numbers are down from the opener of Fighting Illini -2.5 (-105) and the high point of the juice at -2.5 flat in 2026 Final Four odds.

Slim underdog UConn is taking more tickets so far, on the spread and moneyline, at 61% and 64%, respectively. But early money favors Illinois, at 54% on the spread and 67% on the moneyline.

The March Madness futures market could determine theScore Bet's need come Saturday evening.

"Our biggest liability from a futures perspective is UConn. As things stand, any of the other three teams lifting the trophy on Monday night would be a better outcome for us," theScore Bet sportsbook vice president Adam Landeka said.

The total has been painted to 139.5 since Monday night at theScore Bet, after also opening at 139, then spending about 12 hours at 140.5 (Under -115). The Over is landing 71% of early tickets, but money is closer to even, at 54% on the Over.

THIRD UPDATE: Illinois moved from -2 to -1.5 in short order Sunday in Borgata Sports' March Madness Final Four odds. There's been no movement since, with the Fighting Illini at -1.5 as of 1:30 p.m. ET Wednesday.

"As expected with a game lined this closely, the betting action has been relatively split between both teams," Borgata sportsbook director Tom Gable said. "Both Illinois and UConn are good results for us in the national title futures, so no liability to speak of from either side.

"I have a feeling that the public will go with the Illinois moneyline here, and our need will probably be with the Huskies."

And Gable isn't counting out either team's ability to then go on and win the national championship game.

"This game may be seen as the consolation game by some, due to the fact the winner will be an underdog in the national championship game," he said. "But the bottom line is both teams are capable of playing with anyone in the country and still would have a puncher’s chance in the final.."

Borgata's total opened and remains 139.5.

SECOND UPDATE: As of 2 p.m. ET Monday, Illinois is -2.5 (-102) in DraftKings Sportsbook's Final Four odds. On Sunday night, the Fighting Illini opened -2.5 flat, quickly dipped to -1.5 (-120) and steadied at -2.5 (-102) after a couple of hours.

Early spread play is solidly on short underdog UConn, at 68% of tickets/69% of money. Moneyline action is similarly on the Huskies, at 71% of tickets/69% of money.

DraftKings' total is at 139.5, going there minutes after opening at 140.5 Sunday night. The Over is netting 76% of early tickets/78% of early money.

OPENING ODDS UPDATE: No. 2 UConn (33-5 SU/16-22 ATS) trailed No. 1 Duke by 19 in the first half and 15 at the break, 44-29. But the Huskies made a stunning comeback, capped by a final-seconds Duke turnover and Braylon Mullins 3-pointer to win 73-72.

UConn, a 4.5-point underdog, had a poor spread-covering mark in the regular season. But the Huskies continue to be an ATS juggernaut in the NCAA Tournament:

  • 10-0 ATS in the Sweet 16 or later
  • 14-0 ATS in the Round of 32 or later

Meanwhile, after a slow start Saturday night, No. 3 Illinois (28-8 SU/20-16 ATS) ultimately got into a back-and-forth battle with upstart No. 9 seed Iowa. But the Fighting Illini pulled away late vs. their Big Ten rival, claiming a 71-59 victory as 6.5-point favorites.

With 7:27 remaining, the game was tied at 50. Then the Illini finished with a 21-9 run in the South Region final. Illinois is 4-0 SU and ATS in the NCAA Tourney.

Moments after UConn's incredible win, DraftKings Sportsbook opened Illinois -2.5 in 2026 Final Four odds. Within minutes, the Fighting Illini dipped to -1.5 (-120). Check back later for an update on odds and early action.
