March Madness Sports Betting Promos 2026 — Ranked & Explained

All offers on this page have been verified as active and available to new customers ahead of the bracket reveal. Bonus values and promo codes are subject to change — check the "Last verified" date in each sportsbook section.

We ranked the best March Madness betting sites by weighing bonus value, ease of redemption, wagering requirements, and how well each offer maps to the tournament's unique betting calendar.

Our team personally tested every signup flow, deposit process, and bonus redemption on both desktop and the best U.S. betting apps, so the assessments below reflect real experience — not just headline numbers.

We also factored in each platform's depth of NCAA Tournament markets, live betting quality, and ongoing loyalty perks. Here's the complete breakdown of the best March Madness betting promos for 2026.

1. BetMGM Sportsbook – Bet $10, Get $150 in Bonus Bets If You Win

BetMGM's Bet $10, Get $150 offer is one of the sharpest bet-and-get promos available for Selection Sunday 2026 — a low-cost entry point that returns 15x your qualifying stake in bonus bets the moment your first wager wins.

For March Madness, this structure is particularly well-suited to the opening round, where heavy favorites routinely cover, and bettors can unlock the $150 with a high-confidence first pick before deploying the bonus across the more unpredictable rounds ahead. Beyond the welcome offer, BetMGM's live betting depth is among the best in the industry, with in-game lines updating rapidly across every tournament game — an essential feature when bracket chaos strikes.

The MGM Rewards integration also adds long-term value, allowing you to accumulate points redeemable for hotel stays, experiences, and additional betting credit across the tournament.

We Tested This: After placing a qualifying first winning bet using code BetMGM Bonus Code BOOKIESBG150, bonus bets were delivered to our account within approximately 24 hours of the wager settling. The code must be entered during registration — not after your account is created. If you miss this step, the offer will not apply, and customer support cannot retroactively add it.

Honest Con: This is a win-required offer — if your first bet loses, you receive no bonus bets whatsoever. It is not a safety-net or insurance structure. Bettors who want guaranteed value regardless of outcome should look at bet365's win-or-lose offer instead. Availability is also limited to MI, NJ, PA, and WV only.

Promo code: BOOKIESBG150 (must be entered at registration — not after)

2. bet365 Sportsbook – Bet $10, Get $365 in Bonus Bets Win or Lose

The bet365 Bonus Code offer is one of the most straightforward and high-yield promos available for the 2026 NCAA Tournament — you place a $10 qualifying bet and receive $365 in bonus bets regardless of whether that wager wins or loses, making it exceptional value for the entry cost.

In our experience, bet365's platform is particularly strong for March Madness because of its consistently competitive odds across all 67 games, coupled with a robust live betting suite that lets you react in real time to the tournament's notoriously unpredictable swings.

The platform also features regular odds boosts on featured tournament matchups, giving bettors an additional edge on top of the welcome bonus. bet365's edit bet feature — which allows you to modify active wagers before they settle — is a standout tool during a tournament where momentum shifts quickly and early cash-out options can protect your position.

We Tested This: The signup process at bet365 was smooth and completed in under five minutes. Bonus bets were credited within roughly two hours of the qualifying bet settling — one of the fastest turnaround times we recorded across all the platforms we tested for this roundup. No promo code is required, which removes a common point of friction.
Honest Con: The $365 in bonus bets arrives as a single lump credit in most cases, but bonus bets cannot be withdrawn as cash; only winnings generated from them are cashable. Additionally, bet365 is available in fewer US states than BetMGM or DraftKings, so eligibility is worth confirming before you start the signup process.

bet365 Bonus Code for March Madness Key Details

Promo code: No code required
Welcome offer: Bet $10, Get $365 in bonus bets (win or lose)
Minimum deposit: $10
Qualifying bet: $10 minimum on any market

Wagering/playthrough: 1x (bonus bets must be wagered once)
Bonus bet expiry: 30 days from issuance (verify current T&Cs before publishing)
Withdrawal note: Only winnings from bonus bets are withdrawable; bonus stake is non-withdrawable

3. Fanatics Sportsbook – Bet $5, Get $200 in FanCash Instantly

The Fanatics Sportsbook Promo for March Madness is one of the most straightforward and beginner-friendly offers in this roundup — place a $5 qualifying bet and receive $200 in FanCash immediately, win or lose, with no promo code required. With Selection Sunday on March 15 and First Round action starting March 19, signing up now means your $200 in FanCash lands in your account in time to deploy across the opening weekend of the bracket.

The FanCash rewards system gives Fanatics a unique edge no other book in this roundup can match: your FanCash can be used to place additional wagers on any NCAA Tournament market, or redeemed for merchandise at Fanatics.com — the world's largest sports retailer. Fanatics also offers 10 profit boost tokens on NCAA Tournament game days, adding further value on top of the welcome offer for active tournament bettors.

Bettors in North Carolina and Tennessee get an enhanced deal — Bet $5, Get $400 in FanCash ($100/day over 4 days) — one of the largest state-specific bet-and-get offers available from any major US sportsbook heading into the tournament.

We Tested This: The $200 in FanCash was credited to our account immediately after our qualifying wager settled — faster than any other offer we tested in this roundup. No promo code is required, but the promotion must be toggled on in the bet slip before placing your qualifying wager. Missing this step means the offer will not apply.
Honest Con: FanCash expires 7 days from issuance — significantly shorter than the 30-day window some competitors offer. The secondary 10-day matched offer ($1,000 total) also requires you to manually opt in each day, and missing a single day forfeits that day's match. The $200 instant offer and the $1,000 matched offer cannot be combined.

Fanatics Sportsbook March Madness Promo Key Details

Promo code: No code required
Welcome offer: Bet $5, Get $200 in FanCash instantly — win or lose (most states); Bet $5, Get $400 in FanCash in NC & TN ($100/day × 4 days)

Qualifying bet: $5 minimum at odds of -500 or longer
Bonus mechanics: $200 in FanCash credited immediately after qualifying wager settles — must toggle promotion on in bet slip before placing wager
Secondary offer: Up to $1,000 matched in FanCash — bet $1–$100/day for 10 consecutive days (min odds -200); max $100 FanCash/day
Wagering/playthrough: FanCash usable for additional wagers or merchandise at Fanatics.com; winnings from FanCash bets are withdrawable as real cash
Bonus expiry: 7 days from issuance (primary offer); 7 days per day's issuance (secondary offer)
Withdrawal note: FanCash itself is not directly withdrawable — only winnings generated from FanCash wagers are cashable

4. DraftKings Sportsbook – Get $200 in Bonus Bets Instantly + 100% NCAA Tournament Winner Profit Boost

The DraftKingsPromo Code for March Madness offer is particularly compelling because it combines an immediate $200 in bonus bets — credited the moment you deposit, before you've even placed a bet — with a 100% profit boost on the NCAA Tournament winner, making it a two-stage value package that covers both the short and long game of the bracket.

In our experience, DraftKings offers the deepest NCAAB prop market of any platform in this roundup, with player points, rebounds, assists, and first-basket props available for virtually every tournament game — ideal for bettors who want to go beyond spread and total.

The DraftKings Rewards program (previously Crown Rewards) returns real value through contests, bonus bets, and free-to-play pools that run throughout the tournament. The platform's parlay builder is also exceptionally polished, letting you stack same-game parlays with live legs during tournament games.

We Tested This: The $200 in bonus bets was genuinely instant — credited to our account before we had navigated away from the deposit confirmation screen. The 100% profit boost token appeared in the "My Promos" tab within about 15 minutes and required manual activation before placing the futures wager.

Honest Con: The profit boost applies to the tournament winner market only, so its value is tied to your futures pick hitting — a long shot for most bettors given a 68-team field. If you're not interested in futures wagering, the secondary part of this promotion doesn't add much.

DraftKings Sportsbook March Madness Promo Key Details

Welcome offer: $200 in bonus bets instantly + 100% profit boost on NCAA Tournament winner

5. Caesars Sportsbook – Bet $1, Double Your Winnings 10x (Up to $25 Max Bet Per Boost)

Caesars Sportsbook March Madness promo is a bet-and-boost offer that rewards new users with 10 double-winnings tokens, each usable on any wager up to $25, giving you a total potential boost value of up to $250 spread across the opening rounds of the tournament. In our experience, this structure is particularly effective during March Madness because you can deploy one token per game across the First Round, doubling your returns on high-confidence picks without committing your entire bonus to a single bet.

What makes Caesars a strong pick beyond the Caesars Sportsbook Promo Code BOOKIESDYW is the Caesars Rewards integration: every bet placed during the tournament earns Reward Credits and Tier Credits redeemable for hotel stays, dining, and entertainment at Caesars properties nationwide.

The refer-a-friend program adds further value — refer a friend who deposits and bets $50, and you both receive 5,000 Reward Credits, roughly equivalent to $50 in bonus bets. Caesars also offers live streaming of select college basketball games directly in the app, making it a convenient one-stop platform for watching and wagering on the tournament.

We Tested This: Signup completed in under four minutes using code BOOKIESDYW. The 10 boost tokens appeared in the Bonus Drawer of our bet slip within minutes of placing our qualifying $1 wager — no manual opt-in was required after registration. Each token must be applied individually in the bet slip before placing the wager it's intended for; they do not apply automatically.

Honest Con: The $25 max bet per token limits the absolute upside for higher-stakes bettors — a $25 boosted win returns $50, not a life-changing amount. The tokens also expire 14 days from issuance, so bettors signing up on Selection Sunday need to use all 10 before the Sweet Sixteen tips off. Voided or pushed bets do not result in token reissuance.

Promo code: BOOKIESDYW (enter at registration)
Welcome offer: Bet $1, Double Your Winnings on your next 10 wagers — up to $25 max bet per boost token
Minimum deposit: $10
Qualifying bet: $1 minimum at odds of -500 or longer
Bonus mechanics: 10 double-winnings tokens credited after qualifying wager is placed; each token applied individually via the Bonus Drawer in the bet slip; max additional winnings $2,500 per token
Wagering/playthrough: Tokens are single-use; winnings from boosted bets are withdrawable as real cash
Bonus expiry: Tokens expire 14 days from issuance; not reissued for voided or pushed bets
Withdrawal note: Boost tokens themselves are not withdrawable — only winnings generated from boosted bets are cashable

6. FanDuel Sportsbook – Get Up to $300 Back in Bonus Bets Every Day for 10 Days

The FanDuel Promo Code for the NCAAB Tournament offer is structured as a ten-day no-sweat first bet promotion — if your qualifying daily wager loses, you get up to $300 back in bonus bets, repeated across your first ten days of activity.

This timing maps almost perfectly onto the first two rounds of the NCAA Tournament, giving you multiple bites at the apple during the stretch of the bracket where upsets are most concentrated, and picks are hardest to call.

FanDuel is consistently rated among the best betting apps for user experience, with a clean interface, fast-loading live markets, and one of the smoothest same-game parlay builders available. The FanDuel Rewards program delivers ongoing perks, including bonus bet boosts, free-to-play pools, and early payout promos on select tournament games.

We Tested This: FanDuel's daily bonus bet crediting was reliable in our testing — refunds from losing qualifying bets appeared in the "My Bonuses" section within 72 hours, though most arrived within 24 hours. No promo code is required for new customers, which simplifies the onboarding process considerably.

Honest Con: The $300 daily cap only applies if you're placing a single qualifying bet at or near that amount each day. For bettors spreading smaller wagers across multiple games daily, the no-sweat mechanic provides less practical protection than it appears on paper.

7. theScore Bet Sportsbook – Bet $10, Get $100 If You Win

The TheScore Bet Promo Code BOOKIES offer operates on a win-required mechanic — place a $10 qualifying wager, win it, and receive $100 in bonus bets — making it a natural fit for bettors who want to open with a high-confidence pick, such as a strong seed in the First Round.

TheScore Bet's standout differentiator is its native integration with theScore app, one of the most widely used sports news and scores platforms in North America, allowing users to move seamlessly between live game coverage and their betting account without switching apps.

The platform offers solid odds boosts and early payout promos on selected tournament games, and its interface is particularly clean and fast — an advantage when you're trying to get a live bet down during a tight second half. For bettors who already use theScore for scores and news, this is a natural first choice for a March Madness account.

We Tested This: The $10 qualifying bet was easy to place, and the $100 bonus bet credit arrived within a few hours of the winning wager settling. One point of friction: theScore Bet is currently available in a smaller number of states than most competitors — confirm eligibility before beginning registration.

Honest Con: This is a win-required offer, which means if your qualifying bet loses, you receive nothing — it's not an insurance or risk-free structure. For bettors who want guaranteed value regardless of the result, bet365's or Caesars' win-or-lose offers are the safer alternatives.

How to Claim March Madness Sports Betting Promos 2026

Claiming the best March Madness betting promos takes under ten minutes from start to first wager — but the steps matter, particularly when promo codes are involved or opt-in is required before placing your first bet.

Follow this guide to make sure your bonus is applied correctly before tip-off. We've laid it out as clearly as possible based on our firsthand experience testing every signup flow in this roundup.

Step 1 — Choose a Sports Betting Site

Compare the offer structures above and match the bonus type to your betting style — insurance offers (BetMGM) suit high-stakes openers, while win-or-lose promos (bet365, Caesars) suit cautious first-timers.
Confirm the sports betting site operates legally in your state before starting registration — each sportsbook's key details section above lists eligible states.
Use the links on this page to access the correct signup landing page where available promotions are pre-loaded and verified.

Step 2 — Sign Up for an Account

Use the signup links on this page to ensure you land on the correct promotional page — going directly to a sportsbook's homepage may not automatically apply the best available offer.
Have your full legal name, date of birth, address, and last four digits of your SSN ready for identity verification — this is a standard KYC requirement at all US sports betting sites
If a promo code is required (e.g., BOOKIES for BetMGM), enter it during the registration step — not after your account is created.

Step 3 — Deposit Funds

Use a payment method that processes quickly — debit cards, PayPal, and Venmo typically post instantly, while bank transfers can take 1–3 business days.
Research fastest payouts before depositing: some methods (e-wallets, Play+) offer same-day withdrawals, while others may take several business days.
Deposit at least the minimum required amount, but consider depositing enough to place the qualifying bet that maximizes your bonus — a $20 deposit at BetMGM, for example, returns only $20 in bonus bets if your first bet loses.

Step 4 — Place Your March Madness Wager

If your chosen sportsbook requires opt-in before the qualifying bet (Caesars, for example), locate the promo in your account's "My Promotions" or "Offers" tab and activate it before placing any wager.
Review March Madness odds and college basketball picks to identify your qualifying bet — and check college basketball odds for line shopping across the books you've joined.
Confirm your qualifying wager meets any minimum odds requirements (where applicable) before confirming the bet slip.

Step 5 — Withdraw Your Winnings

Once your bonus bets are credited and you've met any 1x playthrough requirements, navigate to the cashier/withdrawal section and select your preferred method.
Note that bonus stakes are almost universally non-withdrawable — only net winnings generated from bonus bets are eligible for withdrawal.
Processing times vary: e-wallets and PayPal typically settle within 24 hours; bank transfers may take 3–5 business days depending on your bank.

Types of March Madness Betting Promos

Not all March Madness sportsbook bonuses 2026 work the same way. Understanding the structure before you sign up helps you pick the offer that best matches how you plan to bet the tournament.

First Bet Insurance / Second Chance Bets — The headline structure at BetMGM. Your first bet is refunded as a bonus bet if it loses, up to a set ceiling. This is best suited for bettors comfortable placing a larger opening wager — perhaps on a Final Four game or championship outright — knowing there's a safety net. The larger your first bet, the more insurance value you unlock.

Bet & Get Offers (Win Required) — Used by BetMGM, DraftKings, and theScore Bet. You place a qualifying wager, and if it wins, you receive bonus bets in return. These work best when applied to high-probability picks — think a top-seeded team in the opening round — where you can unlock the bonus with confidence before deploying it on higher-risk tournament plays.

Bet Match / Win-or-Lose Bonus Bets — The structure used by bet365 and Caesars Sportsbook. A bonus is awarded regardless of whether your qualifying bet wins or loses, making these the most risk-free category in the market. First-time bettors or anyone wanting guaranteed value from the signup process should prioritize this offer type.

If you're new to sports betting, the win-or-lose structures at bet365 (Bet $10, Get $365) and FanDuel (up to $300 back per day for 10 days) are the most forgiving entry points. Both require a low minimum deposit, neither demands a large opening wager to trigger value, and you receive bonus credit regardless of your first result. bet365 is particularly well-suited to genuine beginners — no promo code required, the offer triggers automatically, and the $365 return on a $10 bet is exceptional on a risk-adjusted basis.

Rewards-Focused Bettors → Caesars or Fanatics

Both Caesars and Fanatics tie their welcome offers to loyalty programs that deliver ongoing value well beyond the NCAA Tournament. Caesars Rewards converts betting activity into Tier and Reward Credits redeemable for hotel stays, dining, and entertainment at Caesars properties. Fanatics FanCash is usable across the Fanatics merchandise store — ideal for fans who'd spend on gear anyway. If you view sports betting as part of a broader fan lifestyle and want a promo that keeps giving after the championship game, either of these programs offers genuine long-term upside. See also our college basketball futures page for options to maximize rewards across extended tournament positions.
