US Sportsbooks Roll Out MLB Betting Bonus Promotions in August 2026
Several U.S. online sportsbooks announced new promotional offers for Major League Baseball games in early August 2026. FanDuel introduced a code that grants up to $1,000 in bet‑reset tokens for new users who wager $5 daily for five days. DraftKings offered a $150 bonus bet for a $5 wager on any MLB matchup, confirmed on August 2. BetMGM provided a $1,500 first‑bet guarantee (or a $150 bonus in select states) for new accounts, with details released on August 2. Kalshi launched multiple referral codes (e.g., WTOP15, MLIVE, MASSLIVE1) that give a tiered mystery bonus ranging from $15 to $500 after a $25 trade, targeting specific games such as Yankees vs. Cubs and Red Sox vs. Dodgers. Fanatics Sportsbook released a ten‑day match‑up bonus that can total $1,000 in FanCash for new users who place daily wagers. Additional platforms Polymarket, OG, and other niche sites also posted $20‑$25 bonus offers tied to MLB, PGA, and WNBA odds. All promotions require users to be 18 or older, reside in participating U.S. states, and meet minimum deposit or trade thresholds.
