Best March Madness Betting Sites

When looking for a March Madness betting site, consider the following:

• Betting Markets: The best March Madness sportsbooks offer a range of markets for each tournament game, as well as the tournament overall. The props that the sportsbooks offer depend on the state you’re in, as some jurisdictions regulate betting on collegiate sports differently.
• Competitive Odds: The best March Madness sportsbooks have competitive odds. You’ll find many of the same prices between the platforms, but sometimes the odds greatly differ. Shop around for the best prices for your bets.
• Customer Support: Speedy customer support is helpful. The site should offer multiple channels for assistance (e.g., live chat, email and phone) with prompt and helpful responses. All the sportsbooks we recommend have top-notch customer support, but the experience can differ slightly between platforms.
• Payment Methods: Look for a site that offers various secure and convenient deposit and withdrawal methods, including e-wallets, credit/debit cards and bank transfers. Check the processing times and any associated fees.
• Promotions: Competitive bonuses and promotions provide added value to get you started. Terms and conditions vary based on the platform.
• Reputation and Regulation: Choose a betting site that is licensed and regulated in the state in which you’re located. This ensures you will get paid if you win, your personal and banking information is safe thanks to encryption technology, and the platform has some form of responsible gambling safeguards.
• User Experience: All the March Madness sites we recommend are user-friendly, with intuitive interfaces that make it easy to navigate, place bets and manage your account. A dedicated mobile app is necessary for betting on the go.

Here are some of the best March Madness betting sites to check out.

BetMGM Sportsbook

BetMGM Sportsbook is regarded as a top-notch sportsbook for several reasons, including its generous welcome offer.

BetMGM is helping new users prepare for the tournament by giving them up to $1,500 in bonus bets if their first wager loses. Use the promo code FORBES1500 when signing up.

This means you can take a big swing on an underdog with your first bet and get another crack if it loses.

The field for March Madness hasn’t been set yet. That will take place during Selection Sunday starting at 6 p.m. ET on Sunday, March 17.

The 32 Division I conference winners automatically get a spot in the tournament. A selection committee chooses the remaining 36 teams, 28 of which are guaranteed a place in the tournament as well.

The remaining eight teams compete in four play-in games – dubbed the “First Four” – for the final four spots in the Round of 64 on March 19 and 20.

The Round of 64 kicks off on March 21, with the tournament culminating in the National Championship Game on April 8.

Bettors interested in wagering on March Madness will have plenty of wagers to choose from, starting with standard bets like moneylines, spreads and totals. They can also combine multiple wagers into parlays and same-game parlays.

Regarding prop bets, however, college basketball player props aren’t as extensive as NBA props. Some states, like Ohio, prohibit wagering on college player props.

Some states allow only game props, while others restrict wagering on in-state teams.

Since the betting markets vary by state, check which wager types are available in your state before placing your March Madness bets.

No one online sportsbook has the best odds for the NCAA Tournament.

For the most part, odds are comparable across sports betting sites, so you won’t see many major differences. You may see Duke as a -300 moneyline favorite at one site and a -280 moneyline favorite at another, but you won’t find them as a +300 underdog anywhere.

DraftKings, FanDuel, BetMGM, Bet365, Fanatics and Caesars all have comparable odds.

Still, it can behoove you to sign up for multiple sportsbooks and compare odds.

Small disparities add up throughout the tournament, especially if you’re placing larger wagers or betting on most of the games.

The spread or Over/Under may differ by a half-point, or certain props may have slightly different odds, so taking the time to research odds differences can help boost your profits.
