The bet365 promo code FOX365 unlocks a welcome bonus where you can get $365 in bonus bets, win or lose, with a stake of $10 or more. Other sportsbooks may offer a higher total bonus, but these usually only pay out if your first bet wins, while bet365’s welcome offer gives you $365 regardless of the outcome of your first bet.

BetMGM: Welcome Bonus from the Best March Madness Sportsbook BetMGM stands out during March Madness with its promotional strength and risk-mitigation offerings that appeal to new and experienced bettors. During the NCAA Tournament, the sportsbook frequently introduces odds increases on high-profile games, special insurance offers on parlays and limited-time bonuses tied to key matchups. The platform organizes games by round and tip time, making it easier to manage multiple bets throughout the busy March Madness schedule. Parlay insurance – which allows you to recover credit if a step is missed – is particularly useful in the early rounds when surprises and bracket breaks are common. Its welcome bonus, up to $1,500 bonus 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 powerful during the first weekend of March Madness, when dozens of games are spread across the schedule. The app’s layout makes it easy to switch between matchups, track spreads, and place bets quickly without excessive scrolling. Bet slips remain clean even when creating parlays for the same game or combining multiple tournament picks. This simplicity is important in live betting, when second-half adjustments and late-game free throws can cause totals and spreads to change quickly. FanDuel is best suited for bettors who value speed and convenience on high-volume tournament days. DraftKings: The Best March Madness Betting Promotions for Existing Users DraftKings shines during March Madness by consistently rolling out rotating promotions and special offers tied to tournament games. Punters can expect odds boosts on popular matches, special featured games and bonus betting offers that change with each round, especially during the first weekend when several games overlap.

For players who plan to bet multiple games each day and take advantage of evolving tournament promotions, DraftKings remains one of the most attractive March Madness betting sites. Fanatics Sportsbook: Most Consistent Rewards Structure Fanatics Sportsbook is taking a slightly different approach during March Madness by centering its value around its FanCash rewards system. Instead of a big bonus up front, bettors can collect credits when they place bets throughout the tournament and redeem those rewards on future games or other Fanatics products. This structure works well in the NCAA Tournament due to the high volume of games and widespread fan engagement with underdog upsets and interbracket drama. FanCash rewards can accumulate steadily through multiple bets rather than relying on a single qualifying bet. Although the betting menu is a bit simpler than some major 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 sports betting sites in the US market after its transition from ESPN BET in late 2025. The platform seamlessly connects scores, news and betting markets so users can move from live updates to betting without switching apps. For a tournament that generates significant search traffic, rapid news updates and real-time storylines, this integration can be useful for bettors who follow the progress of the game and scheduling news before making picks. Although theScore Bet doesn’t offer the most extensive betting menus compared to larger operators, its modern interface and strong media backdrop make it a solid choice for bettors who want an engaging March Madness experience.

Caesars Sportsbook stands out during March Madness for bettors who like to combine futures tournaments with long-term rewards.

March Madness Betting Markets Explained The NCAA Tournament offers a wide range of betting options beyond basic spreads. With neutral-site games, a short rest between rounds and significant public betting volume, March Madness markets move quickly and may differ from regular season prices. 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 with more points than the number shown, while the underdog can either win outright or lose with fewer points than the margin. Example: Spreads are often large in the early rounds when higher seeds play lower seeds. Many bettors automatically back the favorites, which can push these lines even higher. This sometimes creates opportunities on underdogs, especially on teams that are better than their seed suggests. Moneyline A moneyline bet means that you choose the team that will win the game. There is no point spread involved. Your team just needs to win. Favorites have negative odds, meaning you risk more to win less. Underdogs have positive odds, meaning you win more if they pull off the upset. Moneylines are especially popular in March Madness because upsets occur every year. Many bettors look for lower-ranked teams that have a realistic chance of winning outright. Over/Under (Game Total) The over/under is the combined number of points scored by both teams. Example: March Madness totals can be influenced by pace, shooting performance, and late game fouls. In close games, teams often intentionally foul in the last minute, which can cause the total to spike. Blowouts sometimes fail if starters are removed late. Since tournament matches are played on neutral grounds, the score may also vary early as teams adapt to unfamiliar arenas. First Half Betting First half bets apply to the first 20 minutes of the match only. Once halftime arrives, the bet is settled. You can bet on the first half spread, the first half moneyline or the 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 fouls, which can have a big impact on spreads and full game totals. They are also useful when you expect a team to get off to a fast start before depth and adjustments are important later. Second Half Bets Second half bets apply to the last 20 minutes of the match only. Sportsbook resets halftime spread and total based on score current. Second half betting is popular when a team gets off to a slow start but is expected to adjust, or when foul trouble and momentum changes the look of the game after halftime. Team Props Team props focus on specific team performance statistics beyond the final score. Other common team props during March Madness include: Team props are useful when you like one side of the game but don’t want to bet on the spread of the entire game. Player Props Player props allow you to 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 issues matter just as much. Futures Futures are long-term bets placed before or during the tournament. Common March Madness futures include: Example: Arizona +1,200 to win the national championship. Futures odds change after each round. Because the tournament is single elimination, an upset can radically change the game. Live Betting Live betting allows you to place bets after the game has started. Odds are updated in real time based on score, pace and momentum. Example: Duke is down 10 at the start of the match and goes from -6 before the match to +2.5 live. March Madness games often feature point races, making live betting one of the most active markets in the tournament. How March Madness Betting Odds Work March Madness betting odds display both probability and win. They tell you which team is favored and how much you stand to win based on your risk. Most American sportsbooks use American odds, displayed with plus (+) and minus (-) numbers. Understanding how these numbers work helps you compare prices and find better value on different sportsbooks. [March Madness Winner Odds Widget] American Odds Format Most American sportsbooks display odds using the over and under format. American odds are based on a $100 win criteria. A number minus (-) indicates the favorite. This shows how much you have to risk to win $100. Example: UConn -150 A plus (+) number indicates underdog. It shows the profit you earn on a $100 bet. Example: Iowa State +220 A $100 bet would return $220 in profit. A $50 bet would pay out $110. In the early rounds, higher seeds can have heavy negative odds compared to lower seeds. As the tournament progresses and matchups become more balanced, moneylines tend to tighten. Point Spread Odds and -110 Standard Most point spreads and totals are valued around -110 on either side. Example: Kansas -6.5 (-110) Gonzaga +6.5 (-110) This extra $10 is known as the sports betting margin, often referred to as vig or juice. It is integrated with the spread and total markets so that sportsbooks can profit regardless of the outcome. In high-profile March Madness games, spreads can change quickly based on public money. A line that opens at -5.5 can move to -7 if big action happens on the favorite. Moneyline vs Spread Moneyline betting only requires one team to win the game. Spread betting requires 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 provides a higher payoff but requires Kentucky to win by 8 points or more. During March Madness, moneylines are especially popular in the early rounds when bettors look for upset opportunities on lower-seeded teams. Futures Odds and Tournament Prizes Futures odds are much higher because the bet must last over several rounds. Example: Duke +1,200 to win the national championship. Futures odds change after each spin. A team that starts at +2500 can drop to +600 after reaching the Elite Eight. Since the NCAA Tournament is single elimination, futures carry higher volatility than most betting markets. An upset eliminates the team completely. Why Odds Move During March Madness Odds movement is common throughout the tournament. Lines can change for the following reasons: For example, if a No. 12 seed wins convincingly in the first round, sportsbooks can quickly adjust the line for the next matchup based on performance and public perception. Comparing odds between sportsbooks can sometimes reveal small price differences, especially on moneylines and futures. March Madness Betting Strategy and Tips The NCAA Tournament is played differently than the regular season. Matches take place on neutral grounds, teams face unknown opponents, and the volume of public betting increases significantly. For this reason, some strategies that work in January don’t always apply in March. Here are some handy betting tips for navigating March Madness. Expect public money for Top Seeds Top programs and No. 1 Seeds attract strong betting action each year. When the public loads up on favorites, spreads can increase more than the actual matchup would suggest. This doesn’t mean favorites can’t win, but it can create inflated numbers. Underdogs, especially experienced mid-tier teams, often become attractive options against the spread in early rounds. March Madness games feature neutral courts on neutral floors. There is no real home-field advantage. Teams that rely heavily on crowd energy or home shooting may perform differently in tournament settings. The distance covered and the presence of fans can still be important, but they are rarely as strong as on the field during the regular season. When evaluating matchups, focus more on style and depth than location. Pace and Matchups Generate Totals Not all high-scoring teams create high totals. If a fast-paced team faces a slow, defensive opponent, the total can go down. Tournament pressure can also slow down early round matches, especially in the first half. Late game fouls can drive up totals in close games, so game script is important. Depth Becomes Important During Short Rests Teams play multiple matches over a short period of time during the tournament. Programs with deeper rotations can maintain intensity throughout rounds, while teams that rely heavily on one or two players can become exhausted. Fouling problems are also amplified in single-elimination games. Line Movement Tells a Story March Madness lines move quickly because betting volume is so high. If the gap moves significantly without news of major injuries, this may indicate violent action by one side. While line movement alone does not constitute a betting strategy, monitoring changes before the announcement can provide insight into where the money is going. Futures create hedging opportunities. If you place a futures bet early and your team advances, you might have opportunities to hedge in later rounds. Example: If you bet Texas +2000 before the tournament and they reach the Final Four, you can bet that their opponent will profit regardless of the outcome. As this is a single elimination tournament, the value of futures can change significantly after each victory. Managing your bankroll during the first weekend The first two rounds feature dozens of games over just a few days. It’s easy to overextend yourself during a busy schedule. Spreading bets across too many games can increase the risk without increasing the advantage. Many bettors focus on selected matches rather than betting on every contest. Betting on the first weekend of March Madness The first weekend of March Madness is unlike any other part of the sports calendar. Dozens of matches take place over four days, with several consecutive confrontations. Due to volume and attention, betting behavior changes. Expect Wider Spreads Early first-round matches often feature the No. 1 and No. 2 seeds facing double-digit seeds. This leads to larger spreads compared to later rounds. Public bettors usually lean towards favorites, which can push lines up before the announcement. Underdogs who control the tempo or shoot well from three can become attractive options against the spread in these spots. Underdog Moneylines Are Popular Every year, the lower seeds win outright. For this reason, Moneyline betting becomes especially popular in the first round. Bettors often target 10 to 13 seeds that match well stylistically with those of higher-ranked opponents. Upheavals happen, but they are not guaranteed. Choosing spots carefully matters more than blindly supporting every underdog. Increased promotional volume Sportsbooks tend to increase promotional offers during the first weekend. You may see: Given the large number of matches played, this is often the most aggressive promotional period of the tournament. Click here to check out the latest sports betting promotions available. March Madness Bracket Betting Explained March Madness isn’t 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 bets. You can bet on: As the tournament is single elimination, the odds change quickly after each round. Early bets can create hedging opportunities later in the bracket. Betting on Region Winners Instead of choosing the overall champion, bettors can focus on a single region. Example: Tennessee +450 to win the Midwest region. Regional betting reduces volatility compared to full championship futures because fewer games are involved. Exact Props for the Final Four or Championship Game Some sportsbooks offer specialized props such as: These bets result in higher payouts but are more difficult to make because multiple outcomes must line up. Start Performance Props Another bracket-related option involves betting based on starts. Here are some examples: These accessories allow bettors to have a broader view of the picture without choosing a specific team. Bracket Contests vs Sports Betting Bracket contests and sports betting are different. Bracket contests typically require selecting the entire tournament before matches begin and scoring points based on correct choices. Sports betting allows nt to bet on individual games or futures which can be adjusted as the tournament progresses. Understanding the difference helps bettors choose the format that suits 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 regional betting, others focus on daily gaming markets, and some rely heavily on tournament promotions. Choosing the best March Madness betting site depends on how you plan to bet – whether it’s slice futures, player props, daily spreads, or big promotional bets during the first weekend. Best for March Madness futures betting bet365 is generally one of the strongest options for futures tournaments. Sportsbooks release national championship odds early and offer in-depth markets such as Final Four, region winner and conference performance props. As teams advance, futures prices are quickly updated, giving bettors the opportunity to hedge or add positions throughout the tournament. Best March Madness Betting Sites for Promotions BetMGM and DraftKings typically run the most aggressive March Madness promotions. BetMGM often offers insurance-type deals and larger welcome bonuses tied to tournament action. DraftKings frequently offers odds boosts, profit boosts, and game specials during high-profile matchups. Both sportsbooks tend to increase the frequency of promotions during the first weekend and the Final Four.

This includes points, rebounds, assists, three-pointers, and combined stats such as points, rebounds, and assists. These sportsbooks are useful for bettors who prefer to target individual matches rather than full game spreads. Best for Ongoing Rewards and Benefits Fanatics Sportsbook emphasizes ongoing rewards through its FanCash system. Punters who place bets throughout the tournament can accumulate value across multiple matches rather than relying on a single bonus. Caesars Sportsbook is another great option in this category thanks to its casino rewards ecosystem.
