Polymarket offers new users a $50 trading bonus with $10 deposit during US Open

Polymarket is running a limited-time promotion that awards a $50 trading bonus to new users who fund their account with $10 using the promo code NYPMAX1. Once the code is verified during registration, the bonus is credited automatically and can be applied to any market, from the 2026 US Open tennis matches to daily baseball games, college football and NFL contests. The offer is available to eligible residents of most U.S. states, though it excludes locations such as Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, Ohio and Washington.

Polymarket operates through its US app as an affiliate of Polymarket US and the CFTC-regulated Polymarket Clearing exchange. Participants must be 18 or older, and the promotion carries the usual disclaimer that trading can result in a total loss. The promotion aims to attract bettors during the high-profile US Open week.
