The best real money March Madness betting websites
Before jumping straight in, it is worth checking out our
College Basketball Picks, which are updated daily by experts. All self-respecting online sportsbooks will have odds for March Madness, but it’s a question of which one is right for your needs. So here are five of the best real money online sportsbooks who can give you a superior way to bet on college basketball:
BetMGM - Trusted site for college basketball betting
BetMGM Sportsbook: Pros & Cons
- Plenty of Payment Methods
- MGM Rewards Loyalty Program
- Frequent Promotions
This industry heavyweight can always be counted on to serve up some awesome promos. You won't find one much larger than the current BetMGM welcome offer that will refund your first bet, if it loses, in bonus bets up to $1,500 - perfect for backing those inconsistent teams like Auburn Tigers.
Elsewhere you'll find lots of odds boosts, plenty of basketball betting lines, and a trusted range of payment options. You can bet at BetMGM from these states: Arizona, Colorado, District of Columbia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Mississippi, New Jersey, Nevada, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wyoming.
Caesars - Get ten 100% profit boosts here
Pros and cons of Caesars Sportsbook
- Amazing Caesars Rewards Program
- Highly Competitive Bonuses
- Lots of Payment Methods
All college basketball fans will like what they find at Caesars. Not only does this brand have lots of daily odds boosts and one of the best rewards programs in the business, but it also has a welcome offer that will give you 10 100% profit boosts just for making a $1 qualifying bet. Perfect for making the ultimate start on those first and second rounds of this year's tournament.
Here is the full list of Caesars’ legal states: Arizona, Colorado, District of Columbia, Indiana, Illinois, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, North Carolina, New Jersey, New York, Nevada, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wyoming.
Bet365: Pros & Cons
- One of the Best US Sportsbooks
- Great Live Streaming
- Iconic & Pleasing Design
- Limited Availability in U.S. States
- Interface Can Feel Outdated
This is definitely the rising star of the US betting scene and bet365 will give you a choice of two welcome offers to make a decent start with your CBB bets. If you're backing a favorite like Duke Blue Devils, the $100 bonus bets could be a good deal. However, if you're willing to risk it on a relative outsider like the Louisville Cardinals, then the welcome offer that gives you a $1,000 first bet safety net could make more sense.
Just note that bet365 is only legal in Arizona, Colorado, Indiana, Iowa, Kentucky, Louisiana, New Jersey, North Carolina, Ohio, Pennsylvania, and Virginia.
FanDuel - Heavyweight online sportsbook with top CBB odds
Pros and cons of FanDuel sportsbook
- One of the Best Sportsbook Apps
- Quality Odds
- Clean & Organized Design
- Customer Support Can be Lackluster
Everyone knows that FanDuel is one of the biggest names in sports betting and so it's definitely worth checking out for this year's tournament. You can sign up here and enjoy a huge range of betting lines and nothing but quality odds too.
The best thing is that FanDuel's latest welcome offer will give you $200 in bonus bets if you bet $5. Just note that this first bet has to win, so it might not be suitable if you're betting on someone like the USC Trojans.
FanDuel is legal in most states where sports betting is, and you can bet at the sportsbook from Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Vermont, Virginia, Washington DC, West Virginia, and Wyoming.
DraftKings - So many player prop bets here
DraftKings: Pros & Cons
- Recognizable Green & Black Design
- Dynasty Rewards Loyalty Program
- Top-Tier App
Another massive online sportsbook and DraftKings is probably the place to go if you are looking for the largest amount of player prop bets. DraftKings can also be counted on to serve up some seriously generous promos. For example, signing up here and making a $5 bet will get you $150 in bonus bets - win or lose.
Once again, this sportsbook is widely available, meaning that you can use it for College Basketball betting from the states of Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia, and Wyoming.
Top social sportsbooks for March Madness betting

Pros and cons of using social sportsbooks vs real money sportsbooks

Pros and Cons of Bonus betting

Key ingredients of the best March Madness betting sites
All of these March Madness betting sites will have their unique charms, but they have to each have the following features before we recommend them to you:
The sportsbook has to be legally available in the state that you are playing from, regardless of whether you are betting with real money, or are making predictions with virtual currencies.
You’ll want plenty of flexibility over how you make your predictions of each game in March Madness. This means endless lines for spreads, totals, player props from the First Round to the Final Four and the Grand Final itself.
We’ll be checking each deal to see how it applies to March Madness betting and examine the small print to ensure that it’s good value.
Every March Madness betting site will have to be able to look after their customers. This should mean being able to get help 24/7 via live chat, email, phone and email social media.
You should get to use a variety of payment methods to make deposits at real money sportsbooks as well as optional purchases of Gold Coins packages at social sportsbooks. This should also apply to withdrawing real money winnings or redeeming any Sweepstakes Coins for cash prizes.
How to enjoy NCAA March Madness betting
So let’s take a closer look at how you can actually use one of these sportsbooks for betting on March Madness. Here is a rough guide to what you’d have to do:
- Visit the sportsbook from your browser or download the brand’s app
- Create your first ever account by filling in the registration form with your personal details
- Enter any promo codes required to activate the welcome offer
- Make a real money deposit with one of the accepted payment methods
