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 last couple of NCAA women's finals have been the most wagered on female events 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 use alongside the most common bet types for March Madness betting in 2026.
Early rounds and equal footing
Parity is emerging as a noticeable trend in March Madness. Look no further than the NC State Wolfpack. The 11th-seeded North Carolina-based school made it to the Final Four two years ago, marking one of the most incredible Cinderella runs in recent history. Bettors should take advantage of this newfound 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 are on the spread. The point spread accounts for the final score and the 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 lower-ranked opponents, such as No. 1 vs. No. 16. The spreads shrink as the competition tightens.
Covers tip
Most March Madness betting sites display odds in American format, while some show fractions or decimals. Use our odds calculator to switch between formats and determine potential payouts.
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 available price for your March Madness bets is vital to a successful betting strategy. Sometimes, betting sites are less willing to risk paying out at large odds. However, the best March Madness betting sites we've featured provide fair odds. For a deep dive on the latest March Madness odds, check out our dedicated guide.
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 from the appropriate regulator in the jurisdiction.
Banking and Payout Speed
Securing your winnings promptly is important. Stick to sportsbooks that 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 built into your March Madness betting options should not be overlooked. 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 2026 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 2026
We've outlined several tips and tricks you can have in your back pocket when wagering with the best March Madness betting sites in 2026:
Mix and match Final Four selections
A major favorite may look like a universal lock to make a deep run before the tournament starts, but then fall victim to an early round upset. It's smart to 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 a No. 1 can happen, but it is rare. Make different selections across each of the pools you enter. Going against the grain can help you make up ground on others in the pool, but be selective.
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 bragging rights and big-money prizes could be all yours.
