US Sports Betting Platforms Offer MLB Promo Bonuses in August 2026

In early August 2026 several U.S. sports‑betting operators launched promotional offers tied to Major League Baseball games. DraftKings promoted a "Bet $5, Get $150" code for Thursday’s matchups, while Bet365 offered a "Bet $10, Get $150" bonus (code BROAD365) for wagers on the Nationals‑Phillies game and other MLB contests. BetMGM released two state‑specific codes: SDS150 for Michigan, New Jersey, Pennsylvania and West Virginia, granting a $150 bonus on a $10 winning bet, and SDS1500 for all other states, providing a $1,500 first‑bet guarantee if the initial wager loses.

Polymarket, a prediction‑market platform, introduced a series of $20 trading‑bonus invite codes – ELITE1, CUSE, MASS, OREGON, SILIVE – each requiring a $10 deposit to receive $20 credit for betting on MLB, NFL and other events. The offers are limited to new U.S. users, with eligibility varying by state and code. All promotions are active between August 5 and August 7, 2026, and are subject to standard age and residency requirements.
