Latest March Madness betting news
March Madness betting tips and trends
One of the biggest annual sports events in the United States, March Madness attracts millions of spectators and sports bettors alike. Not just for the men's tournament either, as the 2024 NCAA women's finals between Iowa and South Carolina was the most bet on women's event ever.
Check out our how to bet on March Madness guide for a full rundown on the wide range of wagers and their supported strategies, but point spreads, Over/Under totals, and moneylines are the most popular bets placed during the NCAA basketball tournament. Meanwhile, here are several tourney-friendly tips to employ along with the most common bet types used for March Madness betting in 2025.
Early rounds and equal footing
Parity is starting to emerge as a noticeable March Madness trend. Look no further than the NC State Wolfpack. The 11th-seeded North Carolina-based school made it to the 2025 Final Four, marking one of the most incredible Cinderella runs in recent history. Bettors should take advantage of this new-found parity during the early rounds of the tournament when there tend to be larger point spreads.
Winning propositions
The much-loved prop bets are sports’ answer to coloring outside of the lines. These alternative, and often obscure wagers are not tied directly to the outcome of any college basketball game. Instead, they focus on elements of an individual game rather than the outcome. Think things like the number of 3-pointers made in a game, or the number of times a commentator mentions ‘Cinderella.’ Ultimately, these March Madness props are a great way to add variety to your betting portfolio.
Spreading the love
Most March Madness bets during the tourney come from betting the spread. The point spread takes into account the final score and accompanying margin of victory. You will likely see larger point spreads during the tournament’s opening rounds. This is a result of higher-ranked teams playing a lower-ranked opponent, like No. 1 vs. No. 16. The spreads start to shrink as the competition tightens.
Covers Tip:
The majority of March Madness betting sites will display odds in American format, while some will show fractions or decimals. Use our odds calculator to switch between formats and determine potential payouts.
March Madness betting odds 2025
The Connecticut Huskies became the first team to repeat as national champions since the Florida Gators in 2007, after winning the 2025 NCAA Men's National Championship. Looking ahead to next year, the Huskies have the second-best March Madness 2025 odds.

Recent NCAA men’s basketball national champions
Fan and school allegiances run high, which is why big money is bet on their teams to win the national title. Keep in mind, however, that only a few teams outside of a No. 3 seed have won the national championship. Be sure to check out our March Madness picks as the tournament nears for expert insight and analysis.
- 2024: UConn (+2,000)
- 2023: UConn (+8,000)

What makes a great March Madness betting site?
Bonuses and Promotions
No bettor should leave free money on the table. Read the terms and conditions tied to special offers and sportsbook promotions to make sure that you are getting the most out of your college basketball betting experience.
Best odds
Locating and securing the best price available for your March Madness bets is vital to a fruitful betting strategy. Sometimes, betting sites will be less willing to risk having to pay out at large odds. However, the best March Madness betting sites we've featured provide fair odds.
Key Features
Look for sportsbooks that go the distance with a robust lineup of features, not a one-and-done scenario. Today’s beginner or experienced bettors want mobile apps, live betting, and statistical breakdowns, among the preferred details.
Security and Trust
In the grand scheme of things, a busted bracket is not the worst thing that can happen to you during the tournament. Eliminate unnecessary risk by registering with sportsbooks that hold a valid license for the jurisdiction from the appropriate regulators.
Banking and Payout Speed
Securing your winnings in a timely fashion is important. Stick to sportsbooks which offer quick payout and processing times. The regulated operators listed here offer several of the top sportsbook deposit and withdrawal methods.
Betting Options
Having flexibility inherent in your March Madness betting options should not be thoughtlessly passed over. As you mature as a bettor and garner experience, an online betting site that offers the most betting opportunities will become increasingly important. For example, most March Madness bettors will want the ability to wager on futures markets, such as who will win the March Madness MVP.
Mobile Apps and User Interface
The best March Madness betting sites for 2025 also have the best sports betting apps — or at least a mobile-friendly website. Look for interfaces that are uncomplicated and easy to navigate for the best experience.
Customer Support
Customer service agents can’t help you to predict upsets, but they can prevent you from getting upset about your sportsbook registration. Top March Madness betting sites typically offer 24/7 customer service, detailed FAQs, and contact channels via email and/or social media.
Tips for March Madness bracket betting 2025
We’re not here to cast judgment on the number of brackets you fill out but be warned that others in your office pool will chastise you for completing too many. Regardless of the route you take, we encourage you to download our printable March Madness bracket and consider our expert tips for filling out an NCAA bracket from professional bettors.
Mix and match Final Four selections
The Gonzaga Bulldogs looked like a lock on paper in 2022, but they didn't reach the Final Four and should not have been picked in more than 50% of the pools you entered. Why? Well, they got bounced before the Elite Eight. Choose different combinations for later rounds and mix up your national champion picks for a well-rounded March Madness betting strategy.
Don’t get so upset, because there will be upsets
It is a virtual certainty that one or more heavy March Madness betting favorites will fall. Picking a No. 16 seed over No. 1 can happen, but remember, it has only happened twice in tournament history (2018 UMBC, 2023 Fairleigh Dickinson). Make different selections across each of the pools you enter. Going against the grain can help you make up ground against others in the pool but try to be selective. If you're struggling, take a look at Covers' bracket prediction for inspiration.
Method to the March Madness
Going with your gut is a tried, tested, and often true form of picking a winning March Madness bracket. In the end, it is up to you as to which preferred method to roll with. Much like investing, a diversified portfolio mitigates your exposure to risk. Going down that road leaves you with a good chance to win at least one of your pools this year.
If the mundane office or group chat pool is not cutting it, consider entering one or more free March Madness bracket contests. The subsequent bragging rights and big money prizes could be all yours.
