The bet365 promo code FOXSPORTS unlocks a welcome bonus where you can get $150 in bonus bets, win or lose, with a wager of $5 or more. Other sportsbooks may offer a higher total bonus, but those usually only pay out if your first bet wins, while bet365’s welcome offer gives you $150, regardless of the outcome of your first bet. With all the volatility and upsets in the NCAA tournament, you may want to be cautious with your betting strategy and go for the guaranteed bonus. BetMGM: Best March Madness Sportsbook Welcome Bonus BetMGM stands out during March Madness for its promotional strength and risk-mitigating offers that appeal to both new and experienced bettors. During the NCAA Tournament, the sportsbook frequently introduces odds boosts on high-profile games, insurance specials on parlays, and limited-time bonuses tied to key matchups. The platform organizes games by round and tip times, making it easier to manage multiple bets across the packed March Madness schedule. Parlay insurance — where you get some credit back if one leg misses — is particularly useful during early rounds when surprises and bracket busters are common.Its welcome bonus, up to $1,500 in bonus bets back if your first bet loses with code FOXSPORTS, is among the most generous available for the tournament and provides a cushion for early upsets. FanDuel: Best NCAA Tournament Betting App Interface FanDuel is especially strong during the first weekend of March Madness when dozens of games are spread across the schedule. The app layout makes it easy to jump between matchups, track spreads, and place wagers quickly without excessive scrolling. Bet slips remain clean even when building same-game parlays or combining multiple tournament picks. This simplicity matters during live betting, when second-half adjustments and late-game free throws can swing totals and spreads rapidly. FanDuel is best suited for bettors who value speed and usability during high-volume tournament days. DraftKings: Best March Madness Betting Promos for Existing Users DraftKings shines during March Madness by consistently rolling out rotating promotions and special offers tied to tournament games. Bettors can expect odds boosts on popular matchups, featured game specials, and bonus bet offers that change throughout each round, especially during the first weekend when multiple games overlap. The sportsbook integrates these promotions directly into the game pages, making it easy to spot boosted markets without digging through separate promo tabs. Whether it’s a parlay boost on multiple underdogs or a bracket performance special, DraftKings gives active bettors plenty of opportunities to find value. For players who plan to bet multiple games each day and take advantage of evolving tournament promos, DraftKings remains one of the most engaging March Madness betting sites. Fanatics Sportsbook: Most Consistent Rewards Structure Fanatics Sportsbook takes a slightly different approach during March Madness by centering its value around its FanCash rewards system. Instead of one big bonus up front, bettors can earn credit back as they place wagers throughout the tournament and redeem those rewards on future games or other Fanatics products. This structure works well in the NCAA Tournament because of the sheer volume of games and the widespread fan engagement with underdog upsets and bracket dramas. FanCash rewards can accumulate steadily through multiple bets rather than relying on a single qualifying wager. While the betting menu is a bit more streamlined than some larger sportsbooks, Fanatics appeals to bettors who enjoy consistent rewards and smaller, repeat value throughout March Madness. theScore Bet: Best New March Madness Betting Site theScore Bet is one of the newest major sportsbooks in the U.S. market after transitioning from ESPN BET in late 2025. The platform seamlessly connects scores, news, and betting markets so users can jump from live updates into wagers without switching apps. For a tournament that generates heavy search traffic, fast news updates, and real-time storylines, this integration can be useful for bettors tracking game flow and lineup news before making picks. While theScore Bet does not have the deepest betting menus compared to the largest operators, its modern interface and strong media context make it a solid choice for bettors who want an engaging March Madness experience.

The app offers competitive markets on national championship odds, Final Four props, and region winners, making it a strong option for futures bettors before and during the bracket. Throughout the NCAA Tournament, Caesars also runs odds boosts on high-profile games and parlay specials tied to popular teams. Its clean futures layout makes it easy to track championship odds as teams advance through each round. For bettors who value earning rewards beyond bonus bets, Caesars integrates wagers into its Caesars Rewards program, allowing tournament betting activity to contribute toward travel, dining, and entertainment perks. March Madness Betting Markets Explained The NCAA Tournament offers a wide range of betting options beyond basic spreads. With neutral-site games, short rest between rounds, and heavy public betting volume, March Madness markets move quickly and can differ from regular season pricing. Below are the most common March Madness betting markets and how they work. Point Spread The point spread is the most common type of bet during March Madness. The favorite must win by more than the posted number, while the underdog can either win outright or lose by fewer points than the spread. Example: Spreads are often big in the early rounds when top seeds play lower seeds. Many bettors automatically back the favorites, which can push those lines even higher. That sometimes creates opportunities on underdogs, especially teams that are better than their seed suggests. Moneyline A moneyline bet means you are picking the team to win the game outright. There is no point spread involved. Your team just needs to win. Favorites have negative odds, which means you risk more to win less. Underdogs have positive odds, which means you win more if they pull off the upset. Moneylines are especially popular in March Madness because upsets happen every year. Many bettors look for lower-seeded teams that have a realistic chance to win outright. Over/Under (Game Total) The over/under is the combined number of points scored by both teams. Example: Totals in March Madness can be influenced by pace, shooting performance, and late-game fouling. In close games, teams often foul intentionally in the final minute, which can push the total higher. Blowouts sometimes go under if starters are pulled late. Because tournament games are played on neutral courts, scoring can also vary early as teams adjust to unfamiliar arenas. First Half Bets First-half bets only apply to the first 20 minutes of the game. Once halftime hits, the bet is settled. You can bet on the first-half spread, first-half moneyline, or first-half total. Example (First-Half Spread): Kansas -4.5 (1H) Example (First-Half Moneyline): Baylor -150 (1H) Example (First-Half Total): Over 70.5 (1H) Some bettors prefer first-half bets because they remove late-game fouling, which can heavily impact full-game spreads and totals. They are also useful when you expect one team to start fast before depth and adjustments matter later. Second Half Bets Second-half bets only apply to the final 20 minutes of the game. Sportsbooks reset the spread and total at halftime based on the current score. Second-half bets are popular when a team starts off slow but is expected to adjust, or when foul trouble and momentum change how the matchup looks after halftime. Team Props Team props focus on specific team performance stats beyond just the final score. Other common team props during March Madness include: Team props are useful when you like one side of the matchup but do not want to bet the full-game spread. Player Props Player props let you bet on individual performance. Common player props include: During March Madness, star players often see heavier minutes, which can impact prop markets. However, matchups and foul trouble matter just as much. Futures Futures are long-term bets placed before or during the tournament. Common March Madness futures include: Example: Arizona +1200 to win the National Championship Futures odds shift after every round. Because the tournament is single elimination, one upset can drastically change the board. Live Betting Live betting allows you to place wagers after the game has started. Odds update in real time based on score, pace, and momentum.Example: Duke is down 10 early and moves from -6 pregame to +2.5 live. March Madness games often feature scoring runs, which makes live betting one of the most active markets during the tournament. How March Madness Betting Odds Work March Madness betting odds show both probability and payout. They tell you which team is favored and how much you stand to win based on your risk. Most U.S. sportsbooks use American odds, displayed with plus (+) and minus (-) numbers. Understanding how these numbers work helps you compare prices and find better value across different sportsbooks. [March Madness Winner Odds Widget] American Odds Format Most U.S. sportsbooks display odds using the plus and minus format. American odds are based on a $100 win benchmark.A minus number (-) indicates the favorite. It shows how much you must risk to win $100. Example: UConn -150 A plus number (+) indicates the underdog. It shows how much profit you win on a $100 wager. Example: Iowa State +220 A $100 bet would win $220 in profit. A $50 bet would win $110. In early rounds, top seeds may carry heavy negative odds against lower seeds. As the tournament advances and matchups become more even, moneylines tend to tighten. Point Spread Odds and the -110 Standard Most point spreads and totals are priced around -110 on each side. Example: Kansas -6.5 (-110) Gonzaga +6.5 (-110) That extra $10 is known as the sportsbook’s margin, often called the vig or juice. It is built into spread and total markets so sportsbooks can profit regardless of the outcome. In high-profile March Madness games, spreads can move quickly based on public money. A line that opens at -5.5 may move to -7 if heavy action comes in on the favorite. Moneyline vs Spread Moneyline bets only require a team to win the game. Spread bets require a team to win by a certain number of points. Example: Kentucky -300 (moneyline) Kentucky -7.5 (-110) The -300 moneyline means Kentucky is expected to win comfortably, but the payout is smaller. The -7.5 spread offers a stronger payout but requires Kentucky to win by 8 or more points. During March Madness, moneylines are especially popular in early rounds when bettors look for upset opportunities on lower-seeded teams. Futures Odds and Tournament Pricing Futures odds are much higher because the bet must last through multiple rounds. Example: Duke +1200 to win the National Championship Futures odds change after every round. A team that starts at +2500 may drop to +600 after reaching the Elite Eight. Because the NCAA Tournament is single elimination, futures carry higher volatility than most betting markets. One upset eliminates the team entirely. Why Odds Move During March Madness Odds movement is common throughout the tournament. Lines can shift because of: For example, if a No. 12 seed wins convincingly in the first round, sportsbooks may adjust the next game’s line quickly based on performance and public perception. Comparing odds across sportsbooks can sometimes reveal small pricing differences, especially on moneylines and futures. March Madness Betting Strategy & Tips The NCAA Tournament plays differently than the regular season. Games are on neutral courts, teams face unfamiliar opponents, and public betting volume spikes dramatically. Because of that, some strategies that work in January do not always apply in March. Here are practical betting tips for navigating March Madness. Expect Public Money on Top Seeds Top programs and No. 1 seeds attract heavy betting action every year. When the public loads up on favorites, spreads can move higher than the true matchup suggests. That does not mean favorites cannot win, but it can create inflated numbers. Underdogs, especially experienced mid-major teams, often become attractive against-the-spread options in early rounds. Neutral Courts Matter March Madness games are played on neutral floors. There is no true home-court advantage. Teams that rely heavily on crowd energy or home shooting splits can perform differently in tournament settings. Travel distance and fan presence can still matter, but it is rarely as strong as regular-season home court. When evaluating matchups, focus more on style and depth than venue. Pace and Matchups Drive Totals Not all high-scoring teams create high totals. If a fast-paced team faces a slow, defensive opponent, the total may come down. Tournament pressure can also slow early-round games, especially in the first half. Late-game fouling can push totals over in close matchups, so game script matters. Depth Becomes Important on Short Rest Teams play multiple games in a short span during the tournament. Programs with deeper rotations can maintain intensity across rounds, while teams that rely heavily on one or two players may wear down. Foul trouble also becomes magnified in single-elimination games. Line Movement Tells a Story March Madness lines move quickly because betting volume is so high. If a spread shifts significantly without major injury news, it can indicate heavy action on one side. While line movement alone is not a betting strategy, monitoring changes before tipoff can provide insight into where the money is landing. Futures Create Hedging Opportunities If you place a futures bet early and your team advances, you may have opportunities to hedge later rounds. Example: If you bet Texas +2000 before the tournament and they reach the Final Four, you can bet their opponent to lock in profit regardless of the outcome. Because the tournament is single elimination, futures value can shift dramatically after each win. Manage Bankroll During the First Weekend The first two rounds feature dozens of games over just a few days. It is easy to overextend during a packed schedule. Spreading bets across too many games can increase risk without increasing edge. Many bettors focus on select matchups rather than wagering on every contest. Betting the First Weekend of March Madness The first weekend of March Madness is unlike any other stretch of the sports calendar. Dozens of games tip off over four days, with multiple matchups happening back to back. Because of the volume and attention, betting behavior changes. Expect Bigger Spreads Early First-round matchups often feature No. 1 and No. 2 seeds facing double-digit seeds. That leads to larger spreads compared to later rounds. Public bettors typically lean toward favorites, which can push lines higher before tipoff. Underdogs that control tempo or shoot well from three can become attractive against-the-spread options in these spots. Underdog Moneylines Are Popular Every year, lower seeds win outright. Because of that, moneyline betting becomes especially popular in the first round. Bettors often target 10–13 seeds that match up well stylistically with higher-seeded opponents. Upsets happen, but they are not guaranteed. Selecting spots carefully matters more than blindly backing every underdog. Promo Volume Increases Sportsbooks tend to increase promotional offers during the first weekend. You may see: Because so many games are being played, this is often the most aggressive promotional period of the tournament. Click here to check the latest sportsbook promotions available. March Madness Bracket Betting Explained March Madness is not just about individual games. The bracket itself creates additional betting opportunities beyond spreads and totals. Sportsbooks offer several bracket-focused markets during the NCAA Tournament. National Champion and Final Four Futures These are the most popular bracket-related bets. You can wager on: Because the tournament is single elimination, odds shift quickly after each round. Early bets can create hedging opportunities later in the bracket. Region Winner Betting Instead of picking the overall champion, bettors can focus on one region. Example: Tennessee +450 to win the Midwest Region. Region betting reduces volatility compared to full championship futures because fewer games are involved. Exact Final Four or Championship Matchup Props Some sportsbooks offer specialty bracket props such as: These bets carry higher payouts but are more difficult to hit because multiple outcomes must align. Seed Performance Props Another bracket-related option involves seed-based betting. Examples include: These props allow bettors to take a broader view of the bracket without picking one specific team. Bracket Contests vs Sports Betting Bracket contests and sportsbook betting are different. Bracket contests typically require selecting the full tournament before games begin and scoring points based on correct picks. Sportsbook betting allows wagers on individual games or futures that can be adjusted as the tournament unfolds. Understanding the difference helps bettors choose the format that fits their approach. How to Choose the Best NCAA Tournament Betting Site Different sportsbooks excel at different parts of the NCAA Tournament. Some are stronger for futures and region betting, others focus on daily game markets, and some lean heavily into tournament promotions. Choosing the best March Madness betting site depends on how you plan to bet — whether that is bracket futures, player props, daily spreads, or promo-heavy wagering during the first weekend. Best for March Madness Futures Betting bet365 is typically one of the strongest options for tournament futures. The sportsbook posts National Championship odds early and offers deep markets such as Final Four, Region Winner, and conference performance props. As teams advance, futures pricing updates quickly, giving bettors flexibility to hedge or add positions throughout the tournament. Best March Madness Betting Sites for Promotions BetMGM and DraftKings usually run the most aggressive March Madness promotions. BetMGM often features insurance-style offers and larger welcome bonuses tied to tournament action. DraftKings frequently rolls out odds boosts, profit boosts, and featured game specials during high-profile matchups. Both sportsbooks tend to increase promo frequency during the first weekend and the Final Four. Best for Daily March Madness Betting FanDuel works well for bettors placing wagers across multiple games in a single day. The app layout makes it easy to switch between matchups during busy tournament windows, especially when several games tip off within minutes of each other. For bettors focused on spreads, totals, and simple same-game parlays, FanDuel provides a streamlined experience. Best for Player Props DraftKings and bet365 typically offer the deepest player prop menus during March Madness. This includes points, rebounds, assists, three-pointers made, and combo stats like points plus rebounds plus assists. These sportsbooks are useful for bettors who prefer targeting individual matchups rather than full-game spreads. Best for Ongoing Rewards and Perks Fanatics Sportsbook emphasizes continuous rewards through its FanCash system. Bettors placing wagers throughout the tournament can accumulate value over multiple matches rather than relying on a single bonus. Caesars Sportsbook is another strong option in this category thanks to its casino rewards ecosystem. With Caesars Rewards, you can book stays at Caesars properties, dining experiences, and more, in addition to bonus bets.
