MLB betting promos are stepping up to the plate for the Divisional Round, World Series odds, and more. If you haven't signed up at any of the top online sportsbooks in the country, you are leaving thousands of dollars in bonus bets sitting there like ducks on the pond as we enter the MLB Playoffs! Today, we get four Game 1 matchups: White Sox vs. Guardians (1 p.m. ET, TBS/truTV), Braves vs. Dodgers (4 p.m. ET, FOX), Yankees vs. Rays (6:30 p.m. ET, TBS/truTV), and Padres vs. Brewers (8:30 p.m. ET, FS1).
Sign up for a new account today, make a first-time deposit or trade, and you'll be ready to handle these MLB betting promos with ease. The best sportsbooks for MLB odds offer a wide variety of deals, so if you want to swing for the fences on your first wager, the BetMGM $ 1,500 First Bet offer might be the one for you. However, if you want to bunt your way on board and work station-to-station, I highly recommend the Fanatics Sportsbook $1,000 FanCash Match that works over the course of 10 days. Heck, you can get a whole series in with that deal.
For MLB bettors like me, I am excited to tackle each series, but it won't be easy. These bonus bets are a good way to keep the bankroll intact, especially while the NFL and CFB seasons are still in the early stages. Even if you're signed up for only one of the sports betting apps, not the others, these bonus bets can help you work your way across the many sports on the calendar. Don't forget, the NHL season is already here, and the NBA is on the way.

1. Fanatics Sportsbook Promo Code ACTION26
Riding a cold streak in October baseball is no fun, but this offer makes it easier to stomach. Use the Fanatics Sportsbook promo code ACTION26, bet $1 or more each day at odds of -500 or longer, and any losing wager comes back as FanCash worth up to $100 daily. FanCash is the standout feature here since it converts into bonus bets or Fanatics store gear, so even if your pick gets knocked out early in the Divisional Round, a lost wager doesn't have to be a total loss. This is one of the sharper MLB betting promos to lean on if you're grinding through a full slate of postseason baseball, since the streak keeps paying out well past tonight's first pitch.
The catch is the same as always: you need 10 consecutive days of qualifying bets to hit the full $1,000, and missing one resets the ceiling.

2. BetMGM Bonus Code TOPACTION
Series this unpredictable are exactly where a first-bet cushion comes in handy. The BetMGM bonus code TOPACTION unlocks a $1,500 First Bet offer to deposit $10 or more, place $10 or more on any market tied to today's Divisional Round matchup, and a loss comes back in full as bonus bets.
A win pays out as normal. With lines shifting across markets as the postseason field narrows, this is one of the more useful MLB betting promos for testing a number you're not fully sold on without real downside.

3. bet365 Bonus Code
For bettors who'd rather skip the research and just get a position down, this one's about as straightforward as it gets. Use the bet365 bonus code, bet $10 or more at odds of −500 or shorter, and $200 in bonus bets lands in your account no matter how that first wager settles.
There's no streak to maintain and no condition tied to winning, which makes it one of the cleanest MLB betting promos on this list if you just want to get a bet in before first pitch of tonight's Divisional Round game without worrying about the result of that specific wager.

4. DraftKings Promo Code
This one keeps things simple with the lowest barrier to entry of the group. Use the DraftKings promo code, risk just $5 on any market tied to tonight's Divisional Round action, and $150 in bonus bets comes back regardless of outcome.
Just know the fine print: the bonus arrives as six separate $25 tokens that you must claim individually, and they expire seven days after they land, so don't let them sit once you're in. With MLB betting promos like this, the back-end rules matter as much as the headline number.

5. FanDuel Promo Code
The FanDuel promo code is for bettors who want coverage beyond a single night's slate. Bet $5 on any market each day, and FanDuel issues a reset token good for a wager between $1 and $50. If that token bet loses, the stake comes back in full, up to $50 daily over a seven-day stretch.
Start the cycle tonight, and this MLB betting promo keeps you covered through the rest of the Divisional Round.

6. theScore Bet Promo Code ACTNEWS
This offer carries the second-largest reset on the list and works almost identically to BetMGM's.
Sign up with theScore Bet promo code ACTNEWS, place your opening wager, and a loss returns as bonus bets while a win pays out normally. The app has more clutter to wade through before you reach the bet slip, but the pricing on core MLB markets holds up well, which matters if you're shopping a number of MLB betting promos before first pitch.

| theScore Bet Promo CodeACTNEWS | Bet $10, Get $100 in Bonus Bets If You Win | MI, NJ, PA, WV |
7. betPARX Promo Code TANBONUS
The smallest offer on this list is also the easiest to manage. Sign up with the betPARX promo code TANBONUS and your first wager is insured up to $50. Lose it, and the stake comes back as a bonus bet; win it, and you just collect. No streak to track, no bonus arriving in pieces over several weeks.
If you want a clean, low-maintenance way to get into tonight's Divisional Round matchup, this is one of the simpler MLB betting promos to use.

8. Hard Rock Bet Promo Code
Geography does most of the selling here. The Hard Rock Bet promo code is live in six states and remains the only legal mobile sportsbook option in Florida, which makes it the default choice rather than one option among several for a large chunk of readers looking for MLB betting promos during the Divisional Round.
No code is required to claim the welcome offer, and while it's lighter than some of the resets above, the ongoing daily profit boosts for existing users make it worth keeping active well past tonight's game.

| Hard Rock Bet Promo Code (Click Here) | Bet $5, Get $100 in Bonus Bets | MI, NJ |
9. BetRivers Bonus Code
There's no BetRivers bonus code to enter, since it applies automatically when you sign up. It works in reverse of a typical bet-and-get: a winning first bet just pays out, while the value only shows up if that wager loses. That makes it one of the more genuine hedge-friendly MLB betting promos on this list if you've got a real opinion on tonight's Divisional Round matchup, but it's less appealing if you were counting on bonus bets no matter what.
Terms shift more by state here than with any other book on this list, so check the in-app version for your jurisdiction.
| BetRivers Bonus Code | BetRivers Sign-Up Bonus | BetRivers Legal States |
|---|---|---|
| BetRivers Bonus Code (Click Here) | 2nd Chance Bet: Get Up to a $500 Bonus Bet | MI, PA |
| BetRivers Bonus Code (Click Here) | 2nd Chance Bet: Get Up to a $250 Bonus Bet | NJ |
| BetRivers Bonus Code (Click Here) | 2nd Chance Bet: Get Up to a $100 Bonus Bet | WV |
10. Borgata Bonus Code ACTION
Restricted to New Jersey, but worth a look for anyone in that market. Sign up with the Borgata bonus code ACTION, place a $20 opening wager, and get $100 in bonus bet credits instantly. No waiting for the game to finish or a drip-fed payout schedule.
It's one of the best qualifying-to-bonus ratios among tonight's MLB betting promos, though the bonus bets expire in seven days, so you'll want a plan for the Divisional Round slate before you claim it.

MLB Prediction Market Promos
There are several ways to get in on this weekend's Divisional Round action via prediction markets, and these platforms operate in dozens of states where licensed sportsbooks aren't an option. Texas is the clearest case. A fan with no local sportsbook access but plenty riding on how the bracket shakes out has no way into any of the ten books listed above, since these platforms are effectively the only legal route in for a huge share of the country.
The structure is different too. Instead of the traditional American odds, you buy and sell event contracts that shift in price as other traders weigh in. That's useful on a stretch of games like this one, where lines have bounced around all week depending on the book, so a contract at 65 cents tells you a team's win probability in plain terms, with no moneyline conversion required. Among the broader field of MLB betting promos, the two prediction market options below are live across 42 jurisdictions combined.
For a guide to which online sports betting states aren't in play, check our review to ensure you are in compliance for the MLB prediction market promos.
1. Polymarket Promo Code ACTION
The Polymarket promo code ACTION converts a $10 deposit into a $25 trading bonus, making it the cheapest entry point on this page. Divisional Round contracts are live tonight alongside broader postseason and World Series markets, so a position you take on one series can carry straight into the next round's boards instead of closing the moment a game ends. That makes it one of the more flexible MLB betting promos if you're thinking past tonight's games and toward how the bracket shapes up from here.
One thing worth flagging before you deposit: trading credit isn't the same as withdrawable cash, so check the terms on how that bonus actually converts.

| Polymarket Promo Code ACTION | Deposit $10, Get $25 Trading Bonus | AK, AL, AR, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IN, KS, KY, LA, ME, MN, MO, MS, NC, ND, NE, NH, NJ, NM, NY, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WI, WV, WY |
2. Kalshi Promo Code ACTION2000
Register with the Kalshi promo code ACTION2000, hit $25 in qualifying volume, and you'll unlock up to $2,000 in bonuses. Contracts trade anywhere between one and 99 cents and settle at a full dollar if your side comes through.
Kalshi has Divisional Round contracts running tonight alongside postseason bracket and World Series boards, and that same real-time pricing is a good gut check on lines that have shifted throughout the week. It's a useful companion to the other MLB betting promos above if you want a second read on how the market actually sees a given series.
