Final Four Odds

Houston vs. Duke Odds

• Opening point spread: Duke -4.5 (-115)
• Opening moneyline: Duke -198/Houston +164
• Opening total: Over/Under 136.5 points scored
• Time: 8:49 p.m. ET Saturday (CBS)

UPDATE 8:15 P.M. ET SATURDAY: This line moved between Duke -4.5/-5 several times in just the first couple hours after Caesars Sports posted the game Sunday. That continued into Monday/Tuesday before going to Blue Devils -5.5 for a few hours Wednesday night.

It then got back into the Duke -5/-4.5 mode, and as tipoff approaches, it's -4.5 (-115).

"We took a bet worth mentioning on the Blue Devils earlier this afternoon," Caesars Sports' Rich Zanco said, alluding to some sharp action on Duke. "That being said, there is some strong support on Houston spread and moneyline, including a 3/1 ticket count on the moneyline."

Still, once championship futures are factored in: "We need Houston outright," Zanco said.

The total opened at 136.5, bottomed out at a couple times earlier in the week, then got as high as -137. It just went from 136.5 to 137 in the past 30 minutes.

"The betting public has continued to bet the Over in most of these games. This game is no exception, with us needing the Under," Zanco said.

UPDATE 5:45 P.M. ET SATURDAY: Duke is at -4.5 (-105) in DraftKings Sportsbook's March Madness odds Final Four market. On Sunday, the Blue Devils opened -4.5 (-115) and quickly adjusted to -5.5 (-102).

Since then, it's been a back-and-forth a couple times between Duke -5.5/-4.5. The line has been at some iteration of Duke -4.5 all day today, even with spread tickets running almost 3/1 and spread money 4/1 on the Blue Devils.

Bettors are on Duke moneyline, too, with tickets and dollars running 3/1.

DraftKings' Julian Edlow relayed this comment from the risk room: "Houston ATS will be our biggest rooting interest."

The total opened at 136.5, dipped to 135.5 Wednesday and returned to 136.5 Thursday. Tickets are running 2.5/1 and money 2/1 on the Over.

UPDATE 12:15 P.M. ET SATURDAY: With tipoff still almost nine hours out, Duke is -4.5 (-115) on BetMGM's March Madness Final Four odds board. The line has spent the week toggling between various iterations of the Duke -4.5 opener and -5.5.

The latest move came in just the past few minutes, from Blue Devils -5.5 (-102) to -4.5 (-115). Duke is netting 61% of spread bets/63% of spread money. On the moneyline, it's 57% bets on Houston/72% money on Duke.

"Duke is the most-bet team to cover in the Final Four," BetMGM trading manager Seamus Magee said, noting the book needs an outright underdog tonight.

The total has been painted to 136.5 all week, though with a handful of juice adjustments. It's currently 136.5 (Under -115), with 72% of bets/76% of cash on the Over.

UPDATE 3:30 P.M. ET THURSDAY: Duke opened -5 at The SuperBook, then dipped to -4.5 a couple times, first on Sunday night and again early Monday morning. But the Blue Devils have been steady at -5 (-105) since Monday afternoon, with the SuperBook offering reduced juice on the spread.

"This game is more split than Florida-Auburn. We have more Duke tickets on the spread, almost 2/1, but the money is about the same," SuperBook risk manager Casey Degnon said. "There's not a ton of straight bets on Duke moneyline, but there's a lot of Duke love on moneyline parlays."

The total toggled between 136.5/137/136 Sunday and Monday, and it's been steady at 136 since Wednesday morning.

"We've got some parlays to the Over, and a five-figure bet on Duke's team total Over 70.5," Degnon said.

UPDATE 1:30 P.M. ET WEDNESDAY: Borgata Sports, a BetMGM property in Atlantic City, matched others in opening Duke -4.5. The Blue Devils stretched to -5.5 and are now -5.

"Duke has been such a machine that I wasn’t surprised to see them bet up to -5.5," Borgata sportsbook director Tom Gable said. "We did get some buyback on Houston at +5.5. A lot of the advanced metric sites make this game closer than 5.

"But at this point, the public is believing their eyes and what they have continued to see with Duke. I personally make this game 4, so I would be happy to grab +5.5 or higher on Houston."

On the flip side, Borgata's total hasn't moved at all, sticking at 136.5.

UPDATE 5 P.M. ET TUESDAY: ESPNBET opened Duke -4.5 and is up to -5.5 (even) in March Madness odds for the Final Four. And it's all Blue Devils in the early going.

Duke is attracting 73% of spread bets and 78% of spread money. And by percentage, the moneyline is even more lopsided, at 77% of bets/89% of money on the Blue Devils.

It's worth noting that those betting splits account for all wagers – straight bets and parlays. Still, there's no doubt the betting public is on Duke.

ESPNBET opened the total at 136.5 and is down to 135.5. That said, 83% of bets/70% of dollars are on the Over so far.

UPDATE 4 P.M. ET MONDAY: Unlike Florida vs. Auburn, DraftKings Sportsbook's Johnny Avello said early spread play on this matchup is much more clear-cut. Duke opened -4.5 and has already made a couple trips to -5.5, currently sitting at -5.5 (-105).

"We've taken a little bit more Duke play here. You can expect Duke to continue to take money, on the spread, the moneyline and on moneyline parlays," Avello said.

DraftKings total is steady at 136.5 in Final Four odds.

UPDATE 7:30 P.M. ET SUNDAY: As noted below, Duke opened -4.5 (-115) in March Madness Final Four odds at DraftKings Sportsbook. The Blue Devils briefly advanced to -5.5 (-102), then returned to -4.5 (-118).

But it's all Duke early on the point spread, at 84% of bets/94% of money. Duke moneyline is practically just as popular, with the Blue Devils seeing 79% of early bets/94% of early dollars.

DK's total hasn't budged off 136.5, even with 76% of bets/78% of cash on the Over so far.

UPDATE 5 P.M. ET SUNDAY: No. 1 seed Duke (35-3 SU/26-12 ATS) made it 2-for-2 for No. 1 seeds Saturday. The Blue Devils, 7-point favorites in the East Region final, stifled No. 2 seed Alabama in an 85-65 victory.

Duke brings a 15-game win streak with it to San Antonio, going 11-4 ATS in that stretch.

Houston then made it 3-for-3 for No. 1 seeds. The Cougars put the clamps on No. 2 Tennessee in the first half and kept the Vols at arms length the rest of the way.

Houston (34-4 SU/20-17-1 ATS) led 34-15 at halftime and rolled to a 69-50 victory as 2.5-point favorites in today's Midwest Region final. The Cougars are on a 15-game win streak, part of a 30-1 overall SU spree

DraftKings Sportsbook opened Duke -4.5 (-115) a half hour ago, with no movement so far. Likewise, the total is stable at 136.5. Check back later for updates on this matchup in Final Four odds.

Florida vs. Auburn Odds

• Opening point spread: Florida -2.5
• Opening moneyline: Florida -142/Auburn +120
• Opening total: Over/Under 164.5 points scored
• Time: 6:09 p.m. ET Saturday (CBS)

UPDATE 5:30 P.M. ET SATURDAY: With tipoff looming, Florida sits at -2.5 (-105) in Caesars Sports' final Four odds. The Gators have been some iteration of -2.5 almost all week, save for literally a few minutes at -3 Sunday and a couple hours at -2 this afternoon.

"There's been some interest on Auburn +2.5, including a few healthy five-digit bets. But the public continues to bet the Gators and lay the number," said Rich Zanco, head of college basketball trading for Caesars. "We do extremely well to championship futures on either team."

The total plunged from 163.5 to 160.5 in a hurry Sunday, the spent the week toggling between 160/159.5

The total plunged from 163.5 to 160.5 in a hurry Sunday, the spent the week toggling between 160/159.5. It's now down to 159, but Zanco indicated it's not much of a decision.

UPDATE 4 P.M. ET SATURDAY: DraftKings Sportsbook opened Florida -2.5 and has been at some iteration of that number all week in odds for the Final Four. The Gators are currently -2.5 (-105).

Spread tickets and dollars are in the 2/1 range on Florida. The Gators are also taking 59% of tickets and cash on the moneyline.

DraftKings' Julian Edlow relayed this comment from the risk room: "We're pulling for the underdogs and the Under in both games."

The total opened at 164.5 and immediately went to 162.5/161.5, then 160.5 a couple hours later on Sunday night. It's been at various iterations of 159.5 since Monday afternoon.

And it's two-way play, with 52% of bets on the Over and money running dead even.

UPDATE NOON ET SATURDAY: Six hours from tipoff, BetMGM has Florida -2.5 (-105) in Final Four odds. In fact, the Gators haven't moved off that number all week, sitting at either -2.5 flat, -2.5 (-115) or the current -2.5 (-105).

Spread bettors are leaning toward Florida, at 61% of tickets/58% of money. The moneyline is getting two-way play, with 53% of tickets on Auburn/59% of money on Florida.

"Florida is popular, with the Johni Broome uncertainty," BetMGM trading manager Seamus Magee said, alluding to the Auburn star's elbow injury. "An underdog winning [today] would be great for the sportsbook."

BetMGM opened the total at 161.5 and quickly fell to 160.5 Sunday. The number has been at 159.5 since Tuesday, on two-way action. Ticket count is almost dead even, and 56% of money is on the Under.

UPDATE 3:30 P.M. ET THURSDAY: Like everywhere else, The SuperBook is stapled to Florida -2.5, with no change in the spread so far. The only adjustment stems from The SuperBook offering reduced juice, so it's -105 on both sides of that 2.5.

But early action certainly shows a trend.

"It's all Florida so far, tickets and money. And it's more so public action right now," SuperBook risk manager Casey Degnon said. "There's some Auburn love on the moneyline, but there's still more on Florida there and on parlays/moneyline parlays. It's more Florida on everything."

The total opened at 163 and made its way to 160.5 in short order Sunday night. Wednesday brought another dip to 160, which is where the number sits this afternoon.

"Not a lot of tickets or money on that yet," Degnon said.

UPDATE 1:30 P.M. ET WEDNESDAY: Florida is pinned to -2.5 so far at Borgata Sports, a BetMGM shop in Atlantic City. Perhaps one reason for that: Auburn star Johni Broome's elbow injury.

Broome sat out practice Tuesday and today. But the expectation is that he will play Saturday.

"Obviously, the injury to Johni Broome is looming over this game," Borgata sportsbook director Tom Gable said. "I don’t believe we are going to hear any real news on the health of Broome. So this is really whether you think he is going to be close to 100% or will be compromised, after a week of rest and minimal to no practicing."

The total remains on the move this week, opening at 162.5 and now down to 159.5 in Final Four odds. 

UPDATE 5 P.M. ET TUESDAY: ESPNBET is painted to Florida -2.5 so far, with no movement on the number. There's only been a slight juice adjustment, with the Gators now -2.5 (-115).

Action in Final Four odds isn't as tilted in this matchup as in the Houston-Duke nightcap. But early bettors are leaning into Florida. On the spread, tickets and money are in the 2/1 range on the Gators. On the moneyline, it's 1.5/1 tickets and almost 3/1 money on Florida.

Those splits take into account all action, on straight bets and parlays.

The total is at 160.5 from a 161.5 opener. The Over is landing 64% of early bets, but 58% of early cash is on the Under.

UPDATE 4 P.M. ET MONDAY: Early on in DraftKings' March Madness Final Four odds market, it's been the total on the move. On Sunday evening, the total opened at 162.5, and it fell to 160.5 within a few hours.

"The total has dropped, and I think that's due to a couple of things. One, whether Johni Broome (elbow) is 100%. And two, if you look at the tournament trend, 57% of games have gone Under," DraftKings director of sportsbook operations Johnny Avello said.

There's a third factor, as well, that often comes into play as the stakes get higher.

"This being a Final Four game, maybe things tighten up a little bit, the players are little tighter early in games, so maybe not as much scoring," Avello said.

The spread hasn't moved off Florida -2.5, save for a modest juice adjustment from Gators -2.5 flat to -2.5 (-115).

"There's more money on Florida, but not that much more," Avello said. "These two teams know each other. Trying to pick the winner is harder."

UPDATE 11 P.M. ET SUNDAY: Florida vs. Auburn has been on DraftKings' Final 4 odds board for 3.5 hours and hasn't budged off Gators -2.5. That's despite early action landing solidly on the favorite.

Early spread tickets are running 3/1 and early spread money 7/1 on Florida. Moneyline play is tilted toward the Gators, as well, with tickets almost 2/1 and money beyond 3/1.

The total dipped from 162.5 to 161.5 right out of the gate, then in the past hour fell to 160.5. Ticket count is 2.5/1 money almost 5/1 on the Under.

These SEC rivals met once in the regular season. Florida was a hefty 11-point road underdog and notched a 90-81 upset on Feb. 8. The Over hit on a total of 156.5.

UPDATE 7:30 P.M. ET SUNDAY: With 3:14 remaining in regulation Saturday night, No. 1 seed Florida was in a 75-66 hole vs. No. 3 seed Texas Tech. But the Gators made four consecutive 3-pointers, and the Red Raiders missed the front end of two one-and-ones.

When the dust settled, Florida escaped with an 84-79 victory as 6.5-point favorites in the West Region final. The Gators (34-4 SU/27-11 ATS) are on a 10-game win streak and are 16-1 SU/13-4 ATS in their last 17 games.

On Sunday, Auburn made it 4-for-4 for No. 1 seeds. The Tigers (32-5 SU/21-16 ATS) topped No. 2 seed Michigan State 70-64, narrowly covering as 5.5 point favorites.

Player of the Year candidate Johni Broome suffered an elbow injury midway through the second half. But X-rays were negative, and he returned to the court in the final minutes.

Auburn is on a modest 3-0 ATS upswing, which comes after a five-game ATS slide that was part of a 2-7 ATS stretch.

Florida opened as 2.5-point chalk in DraftKings Sportsbook's Final Four odds, with no movement in the first few minutes. However, the total was quickly on the move, dropping from 164.5 to 161.5.
