Best MLB Betting Promos for Friday's Slate
Each sign-up bonus below takes only a few minutes to claim. Register a new account, enter the bonus code where the app asks for one, make a qualifying deposit, and place your first wager on any MLB market.
The offers split into three buckets. Bet-and-get promos pay you bonus bets no matter how the game finishes, first-bet offers refund a losing opener in bonus bets, and insurance promos hand back a portion of a first-bet loss.
Availability changes by market, so check the sportsbooks by state column in each table before you sign up. Our guide to where sports betting is legal breaks down every live market in the country.
1. Fanatics Sportsbook
The Fanatics Sportsbook promo code ACTION26 matches your first qualifying cash bet each day at 100%, up to $100 in FanCash, win or lose. The offer runs 10 straight days, and stacking every one of them delivers up to $1,000 in FanCash.
Enter ACTION26 at registration, then start the clock with a bet on the Cardinals vs. Cubs afternoon opener. Skipping a day forfeits that day's match, so log a qualifying wager daily to reach the full amount. Fanatics Sportsbook also runs an alternate bet-and-get version in select states, plus instant profit boost tokens in Illinois and New York.

Best MLB Prediction Market Apps on Friday, August 14
Prediction markets reach several states where traditional sportsbooks don't operate, so they open the door for bettors shut out of the offers above.
Both prediction market apps below run referral bonuses that work much like the MLB betting promos at a sportsbook, and both use the same promo code, ACTION.
1. Kalshi
The Kalshi promo code ACTION unlocks up to $500 in bonus funds on a $25 trade, and the platform serves more than 40 states.
Enter ACTION during sign-up, then trade contracts on MLB game outcomes, division races, and season-long questions, including the MLB MVP chase.

2. Polymarket

Add ACTION at registration, deposit $10, and earn a $20 trading bonus, the smallest entry point on this page.

How to Get the Most From MLB Betting Promos on Friday
Claim more than one offer. Nothing stops you from stacking multiple MLB betting promos across different apps, and shopping the same market at two books often lands you a better number.
Time your first bet. Check the MLB weather report before you lock in an afternoon total, since wind at Wrigley swings run projections more than almost any other park.
Do the reading. Our MLB picks and daily MLB odds pages track line moves through the day, so you head into Cardinals vs. Cubs and Yankees vs. Blue Jays with a side already in mind.
Read the terms. Bonus bets carry expiration windows, minimum odds requirements, and single-use rules that vary by book.
