Polymarket has put a fresh incentive in front of new Oregon traders ahead of Tuesday’s Dodgers vs. Braves matchup: a $20 trading bonus on a $10 deposit, available only when the referral code OREGON is entered during registration. The code is active, verified and ready for immediate redemption, but it cannot be added after an account is created.
The timing matters because the matchup is one of the premier MLB action boards on Polymarket, and the promotion is being aimed at traders in Oregon and the Pacific Northwest before the August 25 slate closes in. For a new user, the math is straightforward: deposit $10, enter OREGON at signup, and the account starts with $30 to trade across the catalog of high-volume MLB prediction markets.
That setup is exactly why the code has drawn attention today. Polymarket US operates as a peer-to-peer exchange, so there is no traditional sportsbook house edge; participant supply and demand set the fair market value instead. The platform’s MLB odds update in real time as traders react to news, injuries and market momentum, which makes a promotion tied to a single game more than a generic sign-up offer.
There is, however, one condition that changes the value of the offer completely. New users who skip the code during registration do not receive the $20 bonus, and there is no way to recover it later by adding OREGON after the account is already open. That makes the referral step part of the deal itself, not an extra perk that can be claimed afterward.
Polymarket describes OREGON as part of a broader set of active affiliate codes for Dodgers vs. Braves on Tuesday, August 25th, 2026, with each verified code unlocking the same $20 trading bonus on a $10 deposit. For traders in Oregon, the window is now, not after the account is live. Once the signup is finished, the bonus is gone.
