Polymarket launches OREGON referral code tied to the Brewers-Dodgers NLCS

Polymarket has introduced the $25 referral code OREGON for new users in Oregon and Washington, linking the promotion to the Milwaukee Brewers–Los Angeles Dodgers postseason matchup, according to misryoum.com. The outlet tied the launch to Game 4 of the National League Championship Series on October 15, 2026.

Offer terms and competing promotions

According to misryoum.com, a first deposit of $10 qualifies for an immediate $25 bonus, bringing the starting balance to $35. Users must enter OREGON when registering on Polymarket.com or in the mobile app; the outlet says customer support cannot add the bonus afterward. Standard identity verification applies, with one account permitted per person aged 18 or older.

The outlet identifies OREGON as one of five verified Polymarket referral codes active as of October 15, alongside CUSE, SILIVE, MASS, and CLEVE. It says referral, promotional and invitation codes use the same registration field.

The report also compares two competing offers. Kalshi’s OREGONLIVE55 provides a $55 bonus on a $25 deposit, producing an $80 balance after users complete $25 in trades within seven days. Novig’s OREGON promotion pairs a $10 deposit with $50 in trade credit for a $60 balance. According to misryoum.com, Novig requires users to be 21+ and has thinner markets.

Reported NLCS market prices

Misryoum.com describes substantial price movement on Polymarket US around the series. It characterizes the platform as a peer-to-peer market where trader supply and demand move odds in real time, rather than a sportsbook setting a house-adjusted margin. Its reported Game 4 moneyline prices put the Brewers at 42%, with a 2.35x payout multiple, and the Dodgers at 58%, with a 1.72x multiple.

For a winning margin exceeding 1.5 runs, the report lists the Brewers at 30%, with an accompanying “Yes/No” figure of 70%, and the Dodgers at 42%, with an accompanying figure of 59%. First-five-innings prices are reported at 31% for the Brewers, 52% for the Dodgers and 21% for a tie. The full-game total exceeding 7.5 runs is priced at 50%.

The player markets cited by the outlet put Shohei Ohtani at 16% to hit a home run and 39% to record two or more total bases. Mookie Betts is listed at 15% and 43%, respectively. These are the outlet’s reported prices, not independently verified current quotes.

What it means for prediction markets

• The launch concerns user acquisition, not a change in game fundamentals. The referral incentive targets participation in Oregon and Washington; the report does not quantify new accounts or additional trading volume.
• The reported prices require care. Some accompanying percentages do not reconcile neatly, and the source does not clarify whether all quotes were captured simultaneously.
• Promotional balances are not directly comparable. Polymarket, Kalshi and Novig have different deposit, trading, age and credit conditions, despite each offer being presented as an entry incentive.
