MLB Betting Promos: Best Baseball Sportsbook Bonuses

Here's a quick side-by-side of every MLB betting promo I cover on this page, so you can compare offers before diving into the details.

The Fanatics Sportsbook promo code ACTION350 is my pick if you like betting a little every day rather than one big swing. It spreads a big MLB welcome bonus out over a full week instead of dumping it on you all at once.

To collect the max payout, opt in through your bet slip and place a qualifying cash wager of $20 or more within seven days of registering. Fanatics awards $50 in FanCash each day for your first seven days, provided you log in and claim it daily, so I'd set a reminder since each $50 credit expires just 24 hours after it drops.

💡 My tip: Since your initial $20 qualifying wager only needs odds of -500 or longer, I'd put it on a heavy daily favorite to safely activate the promo. Once the daily FanCash lands, spend it fast on a high-confidence market like a moneyline favorite so you don't lose it to the 24-hour clock.

Alternative MLB promos for new Fanatics Sportsbook users include:

Why Fanatics Is a Real Home (Run) for MLB Bettors

Once you've claimed the Fanatics MLB promo, a few features make it worth sticking around for the rest of the season.

• FanCash rewards: Every MLB bet earns FanCash, typically 1% on straights, 3% on parlays, and up to 5% on Same Game Parlays, which you can spend as bonus bets or on official MLB gear.
• Fair Play injury protection: Fanatics voids player prop wagers, like a home run prop, if the player leaves the game due to injury within a set window, and this applies to both pitchers and batters.
• Deep MLB props: I've found a strong menu of pitcher strikeouts, innings pitched, first-5-innings markets, and batter props like total bases and hits.
• Squad Bets: Fanatics' Squads let you build a parlay around a collective outcome, like three players from one team combining for 5+ hits, instead of needing every leg to hit individually.
• Niche baseball coverage: Fanatics often carries Triple-A, Pacific Coast League, and international baseball odds that most competitors skip.

The BetMGM bonus code TANGET spreads your welcome promo over 10 days instead of one shot. You get a fresh No Sweat Token daily, so a loss on that day's bet comes back as a bonus bet.

💡 My tip: I like using these tokens on slightly riskier daily plays, like an MLB player prop, since a loss just comes back the next day anyway.

Alternative MLB promos for new BetMGM Sportsbook users include:

The bet365 bonus code TAN365 to a straightforward MLB betting promo: Bet $10, Get $200 in Bonus Bets Win or Lose! You must click our links to claim this promo.

For a bigger first bet with more protection, the Get a First Bet Safety Net up to $1,000 in Bonus Bets! offer refunds your stake in bonus bets, up to $1,000, if your first wager loses. I'd point bigger bettors toward this one if you want to wager with confidence on a larger MLB pick.

MLB welcome promos for new bet365 users vary state to state, so here are some other offers to know:

Why bet365 Works for Baseball Fans

• Live streaming: Watch ball games right in the app and bet as they unfold.
• Deep in-play markets: React pitch-by-pitch instead of locking everything in pre-game.

No code needed here. Just use our links to grab the DraftKings promo code offer: Bet $5, Get $200 in Bonus Bets (Paid Over 21 Days) + 3 Months of NBA League Pass On Us! 

💡 My tip: Your bonus typically arrives as multiple smaller tokens rather than one lump sum, so I'd spread them across a full slate of player props or same game parlays instead of one big bet.

What You Get After Claiming the DraftKings MLB Promo

• DK Replay: Bet pitch-by-pitch on replayed historical MLB at-bats even when there are no live games on the slate.
• Combo Props: Markets like pitcher-vs-batter outcomes that you won't find on most other MLB betting apps.
• Sportsbook+ subscription: A paid add-on that unlocks unlimited parlay boosts, which can meaningfully juice a multi-leg MLB parlay's payout.

The FanDuel promo code offer (no code needed, just use our links) rewards you for showing up daily: Get $350 in Bonus Bets! Wager the minimum every day for seven days straight to unlock the full bonus.

💡 My tip: Since each day's loss resets, I'd treat this as a green light to take a daily shot, like a Same Game Parlay on a matchup, and let the safety net absorb the risk.

FanDuel's app stays my go-to recommendation for Same Game Parlays on MLB slates, since the builder tool is fast and the odds update quickly once lineups drop.

theScore Bet promo code TANBONUS gives you a real safety net on your first bet. If it loses, you get 100% of your stake back as five separate bonus bets.

💡 My tip: I'd save this offer for a bet I truly believe in, like a World Series future, since a loss still comes back as usable bonus bets.

theScore Bet's Alternate MLB Betting Promo

Bettors in MI, NJ, PA, and WV get a separate win-only offer through this promotion. It's a lighter commitment than the full reset bonus, so it fits if you'd rather claim a smaller guaranteed win rather than wait on a refund.

The betPARX promo code TANBONUS adds a little suspense to your welcome bonus. A qualifying first bet unlocks a Mystery Bonus Bet issued at random, with real upside if the number lands high.

💡 My tip: You only need a modest first bet to unlock the mystery reward, so I'd put it on a simple MLB moneyline favorite and see where the random bonus lands.

The Xclub loyalty program and betLabs parlay tools are the two features that keep me checking back on betPARX after the welcome bonus is gone, since both add real value to a season-long MLB betting habit.

The Hard Rock Bet MLB promo offer (no code needed, just use our links) keeps things simple: Bet $5, Get $500 in No Sweat Bets! You collect a guaranteed bonus win or lose, paid out across several weeks.

💡 My tip: Because the bonus is guaranteed either way, you don't need to stick only to heavy favorites, just make sure your opening pick clears the minimum odds requirement.

Hard Rock Rewards and regular daily odds boosts on baseball matchups are the reason I keep this one on my shortlist for MI and NJ bettors.

The BetRivers MLB bonus is a second-chance bet that scales by state, so your cap depends on where you're located.

💡 My tip: Since your first bet is covered up to your state's cap, I'd use the full amount on a bet I'm confident in, like a favorite's moneyline, and treat the refund as a free second swing if it misses.

iRush Rewards is one of the stronger loyalty programs in the industry, and the simple 1x playthrough on your refund bet means you can actually cash out your winnings without much hassle.

The Borgata Sportsbook promo code ACTIONBSPORTS is a straightforward win-only offer built for New Jersey bettors, which makes it a natural fit if you're following the Yankees, Mets, or Phillies this season.

Place a qualifying first bet, and if it wins, Borgata credits you bonus bets on top of your cash payout. There's no refund if your bet loses, so this one rewards confidence rather than covering a miss.

💡 My tip: Since there's no safety net if you lose, I'd stick to a moneyline favorite or a simple run line for your qualifying bet rather than reaching for a long-shot prop.

Not every big-number bonus is worth your time, so I dig into the fine print before recommending anything on this page.

Here's what actually moves the needle when I'm ranking MLB betting promos.

• Real value: A big headline number that requires an equally big losing bet isn't the same as guaranteed bonus bets, so I look at what you're actually likely to walk away with.
• The terms that trip people up: Playthrough rules, minimum-odds requirements, and expiration windows decide how usable a bonus really is, and short expirations knock a promo down my list fast.
• How easy it is to claim: Deposit minimums, whether you need a promo code, and how quickly the bonus actually lands in your account.
• Fit for baseball specifically: I favor promos that pair well with deep MLB markets like props, run lines, first-5-innings, and same game parlays.
• The sportsbook behind the bonus: Odds pricing, app quality, payout speed, and loyalty perks all shape whether it's worth sticking around once the welcome offer is spent.

I verify every promo on this page before it goes live and re-check it on a rolling basis, so what you see here reflects what's actually available right now, last confirmed October 24, 2026.

If sports betting isn't legal in your state yet, you can still get in on MLB through prediction markets, daily fantasy sports, and social sportsbooks. Each one offers a different spin on the sport:

• Prediction markets let you trade on real-world outcomes
• DFS focuses purely on player performance
• Social sportsbooks let you play with virtual currency

While these products aren't legally the same as sportsbooks, they offer similar ways to get in on MLB futures and other markets. 

Prediction markets have leaned into baseball in a big way this season, with MLB contracts now sitting alongside markets on politics and entertainment. Instead of betting against a sportsbook, you're trading on the outcome of an event, buying yes or no on a question like whether a team makes the playoffs, and your position is worth more as your call looks more likely to hit.

Get started today by claiming these MLB best prediction market promos:

I'd recommend starting with either the Polymarket promo code or Kalshi promo code. Both provide generous welcome offers and plenty of MLB event contracts to trade on.

Instead of betting against a sportsbook, DFS platforms have you make higher-or-lower calls on individual player stats, like total bases or strikeouts, and string a few picks together into one entry. It's a fast way to play the MLB slate, and it's available in plenty of states where traditional sportsbooks aren't.

Get started today by claiming these MLB DFS promos. My top rec is the Underdog promo code, though the Dabble promo code is a close second.

Social sportsbooks let you enjoy the thrill of MLB betting without wagering real money, since you play with virtual currency on the same moneylines, spreads, totals, and parlays a traditional book offers.

Many also offer a sweepstakes-style coin redeemable for real prizes, and because there's no real-money wagering, they're live in far more states than standard sportsbooks.

You can claim the Rebet promo code, Thrillzz promo code, and/or Bracco promo code to try this format for yourself:

Signing up correctly is the most important part of actually collecting your bonus, so here's the process I'd walk through every time.

1. Click the offer: Start from any of the promo codes or CTAs on this page rather than searching for the sportsbook directly.
2. Enter your details: You'll typically need your name, phone number, email, state of residence, and SSN for identity verification.
3. Follow the terms: Some sportsbooks need you to enter a promo code manually, others apply it automatically when you register via our links, so double-check before you deposit.
4. Deposit and bet: Most offers have a minimum deposit and minimum first wager, so read those numbers before you fund your account.

Part of the fun of picking an MLB betting promo is understanding the different bonus structures you'll come across. Here's what each type actually means for your wallet.

• Bonus bets: A standard offer where new users get bonus credit after a first-time wager, usually with an expiration window attached.
• Deposit match: The sportsbook matches your first deposit with bonus credit, essentially a two-for-one on your bankroll.
• No sweat bets: You get your stake back if your first wager loses, another two-for-one, but only triggered by a loss.
• Daily boosts: Ongoing promos for existing users that improve odds on popular MLB matchups or players each day.
• Profit boosts: Tokens that increase the payout on a winning bet or parlay, usually available to both new and existing users.
• Rewards programs: Ongoing loyalty perks, like Fanatics FanCash, that you earn on every wager and can redeem later.
