Which March Madness betting promo should you choose?

As you learn how to bet on March Madness and take advantage of the associated March Madness betting promos, deciding which sportsbook offers — we recommend claiming multiple — best meet your needs may seem daunting. But in reality, figuring out which of the best March Madness betting promos you prefer likely boils down to one question: What is your risk tolerance?

For most bettors, the answer is low. That’s why numerous sportsbooks have moved towards offering bet-and-get welcome offers and that’s why we also recommend those are the offers you claim if you’re new to the space. Bet-and-get rewards usually have small wagering requirements — $5 is common — and often provide you with guaranteed bonus funds ranging from $100 to $200. FanDuel, DraftKings, and bet365 all have excellent iterations of this promo type.

If, however, you’re a more experienced bettor who balks at the idea of a $150 welcome bonus, then first bet insurance promos are for you. With these, you can risk much higher amounts of real cash to potentially earn a massive payday. Caesars Sportsbook, BetMGM, and bet365 all offer up to $1,000+ rewards, meaning you can register with them to place a first bet up to that amount. If it fails, they’ll return your stake, up to the specified amount, in bonus funds to give you a second chance.

Types of March Madness betting promos

No matter which online sportsbook(s) you opt to do your March Madness betting with, you’re likely to come across the following four bonuses: Deposit matches, bet-and-gets, first bet insurance, and referral bonuses. We’ve broken down each in detail below:

Deposit matches

Few March Madness betting promos are as straightforward as deposit matches. As the name implies, once you register with a sportsbook and make a first deposit, the amount you put down will be matched up to a certain amount in bonus funds.

For example, if a sportsbook is providing a 100% deposit match up to $500 and you meet that maximum amount, you would receive $500 in bonus funds to double your bankroll.

Bet-and-gets

Many of the best college basketball betting sites offer bet-and-get welcome bonuses. These promos generally have low wagering requirements but comparatively high rewards, making them beneficial for newbies. By simply putting down an initial deposit and wager — typically between $5 to $10 — the sportsbook will issue you bonus funds, regardless of whether you win or lose.

Occasionally, some bet-and-get offers will contain additional conditions, such as demanding your first bet win. For example, FanDuel’s previous new-user reward required you to wager $5 or more successfully to unlock its bonus.

First bet insurance

While first bet insurance bonuses are no longer as prominent as they once were due to the rise of bet-and-get offers, they’re still common at several top sportsbooks. These promos are unique in that you must lose your initial bet to trigger them. Once that’s happened, the sportsbook will return your stake, up to a specific amount, in bonus funds.

For example, should a sportsbook provide a first bet insurance offer of up to $1,000, and you place an initial $500 wager on one of your favorite March Madness sleepers and lose, you’ll get $500 back in non-withdrawable bonus funds.

Referral bonuses

Perhaps the most underrated March Madness promo is the sportsbook referral bonus. These rewards — often aimed at active users — will have you refer a friend to the sportsbook via a unique link or code. After your friend signs up and completes any outstanding stipulations, you’ll receive bonus funds. Some of the top referral offers in the industry dole out up to $100 per person.
