Regional Referral Codes Give New Users Up to $500 on Kalshi and $20 on Polymarket

Verified publisher codes are crediting new accounts with bonus funds that are immediately tradable and have already shifted live prediction‑market prices, raising consumer‑protection and market‑distortion concerns.

Overview

As of Aug. 12–14, verified Kalshi referral codes such as OREGONLIVE1 and SYRACUSE are active and promise variable bonus credits up to $500 after a qualifying $25 in trades.
Polymarket’s verified OREGON referral code is live for U.S. users and grants a $20 trading bonus after a $10 first deposit, delivering $30 of starting capital to new accounts.
Publishers including The Oregonian and Syracuse.com are distributing those codes through affiliate programs, which skip Polymarket’s waitlist and seed immediate liquidity for event markets such as MLB and the PGA FedEx St. Jude Championship.
The two platforms work differently: Kalshi is a CFTC‑regulated exchange that matches orders on an order book, while Polymarket uses peer‑to‑peer price setting, and those structural differences shape how bonus‑funded trades move prices.
Offers require new‑account status, identity and residency checks, exclude several states, and impose playthrough and withdrawal limits, and the short‑term effects to watch are price swings during marquee events and any regulatory or platform steps to curb distortions and protect users.
