Polymarket promotions offer $50 bonus after $10 deposit

Polymarket promotional articles published September 22 and 23 described a new-user offer of $50 in trading funds after a $10 deposit and registration with a featured referral code, bringing the stated account total to $60. The accounts said the promotions were tied to Major League Baseball matchups, including Mariners-Astros, Guardians-Red Sox and Yankees-Rays. The promotional copy listed codes including OREGON, CLEVE, MASS, SILIVE and NYPMAX1. It said users had to enter a code during signup, complete identity verification and make the deposit to qualify. The articles presented the bonus as immediately available, but none supplied official offer terms or independently verified that a user received the funds. Eligibility restrictions apply, and the terms may vary by jurisdiction. The articles described Polymarket as a peer-to-peer prediction market rather than a sportsbook. Users trade positions tied to event outcomes, and the promotional material said prices update in real time as participants buy and sell. One report gave Mariners-Astros moneyline prices on September 22 of 56 for Seattle and 45 for Houston.
