How the top March Madness promos compare to each other

Expert Verdict

I consider the current BetMGM welcome bonus the top March Madness promo for the upcoming 2026 tournament, since it provides new users with a large safety net on their first bet. However, all of the sportsbook offers above have their perks. For example, the simple 'bet and get' structure of FanDuel and DraftKings bonuses makes them ideal for bettors who wager only on big events, such as March Madness. If you're looking for value beyond a dollar amount, I'd suggest Caesars and Fanatics since their offers are tied to their great rewards programs. bet365 offers two great welcome bonuses, so you can choose the one that's right for you. Overall, the best March Madness betting promo is the one that aligns with your betting preferences. We go into more detail about each offer throughout this page.

🥇 Top March Madness Betting Promo – BetMGM: $1,500 First Bet Offer

Expert Verdict

The self-proclaimed 'King of Sportsbooks' is undeniably one of the best overall March Madness betting sites in 2026. A major reason is because BetMGM offers the highest-valued welcome bonus, which you can use to wager on its wealth of March Madness betting markets, including single-game winners or outright tournament champions. I also suggest checking out the existing BetMGM college basketball promos you can use alongside your welcome bonus for an even bigger payout.

Expert Verdict

No list of the best March Madness betting promos would be complete without FanDuel. Not only does the iconic sportsbook deliver an excellent FanDuel promo code new-user offer ahead of the tournament, but I also love how streamlined the operator made creating and placing March Madness same-game parlays this year. You can visit 'ParlayHub' for pre-built SGPs and easily create your own using FanDuel's thousands of markets. You can also parlay future bet together. For example, you can get +360 odds on Ohio State and Virginia Tech to both make the NCAA tournament today.

I appreciate the unique nature of the Fanatics Sportsbook promo code new-player deal, as you can secure a daily bonus for your first ten days or receive a lower-cost secondary welcome promo. However, what I appreciate more is that I can earn FanCash, the operator's on-site virtual currency, on day one of using Fanatics Sportsbook. You will get FanCash back on every March Madness wager you place, which you can later redeem for Fanatics' merchandise, including team jerseys, team hats, and more.

Understanding March Madness terms and conditions

We've outlined several common terms and conditions typically attached to the best March Madness betting promos in 2026: 

Best March Madness promos by bettor type

March Madness draws in all kinds of sports bettors every year. We've analyzed and outlined what March Madness promos are best suited for what bettors, depending on their experience and preferences. 

First-time bettors 

If the March Madness is one of the few days of the sports calendar when you wager, then you may be overwhelmed by the amount of March Madness promos available for this year's NCAA men's basketball tournament. We'd suggest only claiming 'bet and get' welcome offers, as they are the easiest to understand, and usually just require a measly initial investment to qualify.

March Madness betting promo suggestion for first time bettors: FanDuel and DraftKings. 

Casual bettors 

Semi-regular sports bettors can rely upon their wagering experience to branch out and claim a wider variety of March Madness betting promos. If you bet casually, and have a decent understanding of the different bonuses available, then we'd suggest claiming tournament-specific odds boosts — which allow you to get a better payout on your wager — and square bets for a bit of added excitement. 

March Madness betting promo suggestion for casual bettors: Caesars Sportsbook and bet365.

Sharp bettors 

Serious sports bettors know the extra value that great March Madness betting bonuses can add to their bankroll. These sharks have seen and claimed all sorts of sportsbook promos, from 'bet and get' to 'deposit matches' and more. For these bettors, we'd strongly suggest targeting operators offering 'second-chance' bonuses, as this bet type allows you to wager confidently, knowing you'll get the full amount back as a bonus if it loses. We'd also recommend securing any profit boost tokens you can find, as these can boost your March Madness bet by a few points, which can mean thousands in extra winnings if successful.

March Madness betting promo suggestion for sharp bettors: BetMGM and Fanatics Sportsbook. 

Common March Madness promo traps to avoid

Every March Madness promo has unique terms and conditions, so you’d be wise to dig into the details before jumping in — skip that step, and you might kiss your reward goodbye.

We’ve pinpointed the critical missteps to dodge when claiming these sports betting sites bonuses.

Allowing promos to expire

First, don’t let promos slip away; most online sportsbooks give you a tight seven-day window, though some, like Caesars, might cut you extra slack — miss it, and your bonus vanishes.  

Not satisfying wagering requirements

Watch for rollover requirements; these playthrough hurdles can lock your bonus until cleared. Many welcome bonuses typically have a 1x wagering requirement, but be sure to analyze the relevant terms to avoid surprises.

Missing minimum odds requirements

Minimum odds can trip you up, too — if the line’s set at -500, betting shorter, like -550, won’t count. 

Wagering on ineligible markets

Stick to eligible markets as well; if the deal demands a same-game parlay, a single-game bet won’t fly.

Not maximizing value 

Finally, maximize your haul — why wager $50 for a promo when $5 could snag you $150 in bonus bets? Know the game, and play it sharp.

Current March Madness betting odds
