March Madness Promos 2026: Claim Over $10,000 in Bonuses

The final First Four games of the 2026 NCAA Tournament are tipping off today, and the biggest names in sports betting have responded with a wave of welcome bonuses that collectively exceed $10,000 in potential value. According to Covers.com, sportsbooks including BetMGM, Caesars, bet365, FanDuel, Fanatics, and DraftKings are all running time-sensitive promotions designed to attract new customers before the bracket heats up. Senior Editor Peter Clarke, who carries 16-plus years of betting experience, reported the details on March 18, 2026.

Top Sportsbook Welcome Offers for March Madness

BetMGM and Caesars Lead With High-Value Structures

BetMGM is offering first bet protection worth up to $1,500, making it one of the highest-ceiling individual offers available right now, according to Covers.com [1]. This type of promotion returns a bonus credit if your first wager does not win, giving new customers a safety net on their opening bet during the tournament.

Caesars Sportsbook is taking a different approach, offering 10 profit boost tokens to new sign-ups [1]. Profit boosts increase the potential return on selected wagers, spreading value across multiple bets rather than concentrating it on a single opening wager.

Both offers are timed to coincide with the First Four games tipping off today, meaning the window to claim them at peak tournament relevance is narrow.

FanDuel, bet365, Fanatics, and DraftKings Round Out the Field

FanDuel, bet365, Fanatics, and DraftKings are each offering instant bonus credits to new customers, according to Covers.com [1]. The exact credit amounts vary by platform, but the structure is consistent: place a qualifying first wager and receive bonus funds back into your account.

The FanDuel promotion is specifically highlighted in the story headline alongside a $25 offer and free gas via a prediction customers mechanic, positioning it as one of the more creatively structured deals of the group [1]. These types of hybrid promotions, combining cash-equivalent rewards with non-cash incentives, are increasingly common during major sporting events.

Covers.com reports that the combined value of all available welcome bonuses across these sportsbooks exceeds $10,000, with individual welcome bonuses reaching up to $3,000 [1].

How These Promotions Actually Work

Minimum Wager and Odds Requirements

Most of the March Madness promos listed by Covers.com require a small initial wager to unlock the bonus, typically $5 or $10 [1]. This low entry point is deliberate: it lowers the barrier for new bettors who want to participate in NCAA tournament betting without committing a large sum upfront.

Minimum odds requirements are also a standard condition across these offers. Covers.com notes that many promotions specify odds of -500 or better, meaning you cannot place a wager on an extreme favourite and still qualify for the bonus [1]. This condition protects sportsbooks from customers placing near-certain winning bets purely to satisfy the promotional requirement.

Reading the terms carefully before placing a qualifying bet is essential, as each sportsbook structures its conditions slightly differently.

Timing Tied to the First Four

The timing of these offers is not coincidental. Covers.com explicitly links the availability of these generous promotions to the final First Four games tipping off on March 18, 2026 [1]. The First Four represents the opening round of March Madness, making it the earliest opportunity for new customers to place a qualifying wager within the tournament context.

Once the main bracket begins, some of these welcome offers may no longer be available to new sign-ups, or the promotional terms could change. Acting before the First Four concludes gives new customers the most options.

March Madness Sportsbook Promos at a Glance

All six sportsbooks listed above are covered in the Covers.com report published on March 18, 2026 [1]. The table above reflects only the information confirmed in that source material. Individual bonus amounts for bet365, Fanatics, and DraftKings were not specified beyond the instant bonus credit structure in the available source text.

The combined total across all available welcome bonuses exceeds $10,000, with the highest single offer reaching up to $3,000, according to Covers.com [1]. New customers who are eligible in their state or region could claim multiple offers by signing up to more than one platform, though each sportsbook’s welcome bonus is available only once per customer.

What Sports Betting Promos Mean for Online Casino Players

For players already familiar with online casino welcome bonuses, the structure of these sportsbook offers will feel recognisable. Both categories typically require a qualifying deposit or wager, carry minimum odds or game restrictions, and deliver value through bonus credits rather than withdrawable cash. The key difference is that sportsbook promos are tied to live sporting events, meaning the window to claim them at maximum relevance is often short.

Fast payout platforms in both the casino and sports betting space share a common appeal: players want their winnings quickly and their bonus terms clearly stated. If you are evaluating any of these March Madness promos, applying the same scrutiny you would to a casino welcome offer, checking wagering requirements, expiry dates, and eligible markets, is a practical starting point.
