Polymarket launches new $25 referral code “OREGON” for Brewers-Dodgers live MLB odds

Polymarket is giving new traders a $25 bonus when they sign up with the code OREGON and deposit at least $10. That adds up to $35 in trading funds right away. The offer is live for people in Oregon and Washington and works for the NLCS Game 4 between the Brewers and Dodgers. The platform lists moneyline odds, over/under, and player props, with prices updating in real time as traders place bets. OREGON is one of several verified codes; others include CUSE, SILIVE, MASS, and CLEVE, all giving the same $25 bonus. The code must be entered during registration, not after. New accounts only, one per user. Polymarket is a peer‑to‑peer prediction market, not a traditional sportsbook, so odds move based on supply and demand. For comparison, Kalshi offers $55 on a $25 deposit and Novig gives $50 on $10, but each has its own rules and age limits.
