January hits different in college hoops. The holiday tournaments are a memory, and conference play starts grinding everyone down into dust. If you’ve been looking at the odds NCAA championship basketball market lately, you’ve probably noticed something weird. The teams we thought were locks back in November? They’re sweating.
The preseason darlings like Purdue and Duke aren’t at the top of the mountain anymore. Instead, we’ve got a Michigan team that seemingly came out of nowhere to become the odds-on favorite. It’s wild. A month ago, you could have gotten the Wolverines at +650 or even higher. Now? They’re sitting at a tight +390 at some books, and the "value" is evaporating faster than a lead in the final two minutes of a March Madness game.
The New Hierarchy of the Oddsboard
Honestly, the way Michigan has jumped everyone is a bit of a shock to the system. They aren't just winning; they are erasing people. Beating Gonzaga by 40 points? That’s not a basketball game; that’s a statement. Most sportsbooks, including FanDuel and BetMGM, now have Michigan as the clear #1 choice, generally ranging between +390 and +440.
But don't count out Arizona. The Wildcats are 14-0 and currently hold the #1 spot in the AP Poll. Usually, the AP Poll and the betting odds move in lockstep, but right now, there's a disconnect. While voters love Arizona, bettors are still slightly more sold on the Wolverines' dominant metrics. Arizona is currently floating around +550 to +700 depending on where you shop.
If you're looking for the usual suspects, they're still in the mix, just further down the list:

- UConn: Hovering at +1000. Dan Hurley’s squad is trying to reclaim their throne after Florida ended their three-peat dream last year.
- Iowa State: A sneaky +1100. They went undefeated in non-conference play and are proving to be a nightmare on defense.
- Duke & Houston: Both sitting around +1200. Duke has the freshman hype with the Boozer twins, while Houston is just... Houston. They’ll defend you until you want to quit.
Why the Preseason Favorites Fell
Purdue opened the season as the team to beat. Makes sense, right? Braden Smith is back, and Matt Painter is a regular-season wizard. But a loss to Iowa State and some shaky performances have seen their odds drift to +1200. It’s not that they’re bad—it’s just that the ceiling for teams like Michigan and Arizona looks higher right now.
Then you have Florida. The defending champs. They’ve had a rough start to 2026, and their odds have ballooned out to +2000 or even +3000. Betting on a repeat is always a massive gamble, but at 30-to-1, someone is going to take that flyer hoping they find their rhythm by February.
Understanding the "Vig" and Line Movement
When you see +400, it basically means a $100 bet wins you $400. Simple enough. But these numbers change every single day. If Michigan’s star gets a "lower-body injury" (the classic coach-speak for a sprained ankle), those odds might jump back to +500.
The "vig" or the "juice" is the cut the sportsbook takes. For futures like the national championship, the vig is actually built into the price. This is why it’s so important to shop around. One book might have Arizona at +550 while another has them at +700. That’s a $150 difference on a hundred-dollar bet. You'd be crazy to leave that on the table.

What Most People Get Wrong About March Odds
The biggest mistake? Thinking the best team in January wins in April. It rarely happens. Last year, Florida wasn't even the favorite for most of the season.
There's also the "implied probability" factor. If Michigan is +390, the math says they have about a 20% chance to win the whole thing. In a 68-team single-elimination tournament, a 20% chance is actually huge. But it also means there’s an 80% chance literally anyone else wins.
Betting the field is usually the smarter play, but humans love a winner. We see Michigan blow out a ranked opponent and we want to get in on the action. Just remember that the tournament is a different beast. One bad shooting night in a high-school gym in Dayton or Boise and your +390 ticket is confetti.
Key Factors to Watch Before Selection Sunday
If you’re trying to find value in the odds NCAA championship basketball before the brackets are even a thought, you need to look at three things:

- Health and Depth: Does the team rely on one guy? If Duke’s Cameron Boozer gets in foul trouble or tweaks something, do they have a Plan B?
- Free Throw Shooting: Sounds boring, I know. But teams that shoot under 70% from the line lose games they should win in March. Check the stats.
- The "KenPom" Metrics: If a team isn't in the top 20 for both offensive and defensive efficiency, history says they aren't winning the title. Michigan and Arizona are currently the only ones firmly in that "Golden Circle."
The AJ Dybantsa Factor
Keep an eye on BYU. They are a longshot at +2500, but they have AJ Dybantsa, who could be the #1 pick in the NBA Draft. Every few years, a superstar talent carries a "non-blueblood" deep into the tournament. If BYU stays healthy, that +2500 is going to look like a steal by the time the Round of 32 rolls around.
Actionable Strategy for Hoops Fans
Don't dump your whole bankroll on a favorite right now. The odds are "short," meaning you're paying a premium because they’re playing well today.
Instead, look for "buy-low" opportunities. If a team like Houston or Purdue hits a two-game losing streak in their conference, their odds will drop. That’s when you strike. You’re betting on the program's pedigree, not just their last 40 minutes of play.
Also, consider "To Reach the Final Four" bets. It’s a lot easier to predict who will be among the last four standing than it is to pick the one team that survives six games in a row. Michigan is currently around -110 to make the Final Four, which tells you just how much the Vegas experts believe in them.
Stay disciplined with your units and don't chase losses on Tuesday night MACtion games. The real money and the real movement in the championship market happen between now and the first week of March. Keep a close eye on the injury reports and the NET rankings, as those will dictate where the money flows next.
Check the latest lines at least twice a week. With the way the Big Ten and Big 12 are beating each other up this year, a "favorite" can become an underdog in the span of one Saturday afternoon.
