Polymarket rolls out new US referral codes with $20 and $50 sports‑betting bonuses

Polymarket announced two new referral codes for U.S. users on August 4, 2026. The code “OREGON” gives new traders a $20 bonus when they fund an account with a $10 deposit, providing $30 of trading capital for MLB, PGA and other major sports markets. The code “SILIVE” offers a larger $50 bonus after a $20 deposit, targeting bettors on games such as the New York Mets vs. Cleveland Guardians and the New York Yankees vs. St. Louis Cardinals. Both promotions are limited to new Polymarket US accounts, require identity verification, and grant unrestricted access to the platform’s full prediction‑market catalog, including MLB odds.

The offers are active only for the day of release and are intended to boost trading volume ahead of high‑profile baseball matchups, including the Los Angeles Dodgers vs. Chicago Cubs game.
