Prediction market platforms continue to implement promotional incentives for new users in the United States, frequently aligning offers with major sporting events. Polymarket has adjusted its promotional structure. While previously offering a $50 trading bonus upon a $10 deposit, the platform is now offering a $25 sign-up bonus for new US users. Under this updated offer, a minimum $10 deposit provides a total of $35 in trading funds for use across sports and politics markets. These bonus funds cannot be withdrawn, transferred, or exchanged. The promotion is available to first-time customers aged 18 and older, though the service remains unavailable in Nevada. Recent promotions have coincided with NFL matchups, such as the Seattle Seahawks versus Denver Broncos, and the MLB National League Championship Series. As of October 15, 2026, Polymarket has launched several specific referral promo codes, including ‘CUSE’, ‘AL25BONUS’, ‘CLEVE’, ‘MASS’, ‘OREGON’, and ‘SILIVE’. These codes offer new users a $25 trading bonus upon a minimum deposit of $10. By October 17, 2026, promotional activity has expanded to include the Sunday Night Football game between the Dallas Cowboys and the Green Bay Packers. Polymarket is seeing high trading volumes for this matchup, with the market priced near a coin flip: the Packers hold an implied probability of approximately 51-52% compared to 48-49% for the Cowboys. The platform, founded by Shayne Coplan in 2020 and headquartered in Manhattan, utilizes the Polygon blockchain for event outcome trading. Kalshi has introduced a $55 trading bonus for new users who trade $25 or more in cash contracts. Novig has also adjusted its incentives, offering a $50 bonus following a $10 deposit. OG Trading Market maintains its ‘Trade $25, Get $25’ welcome promotion for its peer-to-peer exchange using CFTC-regulated event contracts. ~~To qualify, US residents must be at least 18 years old and use a specific promo code to complete a qualifying trade of at least $25.~~
