Polymarket and Kalshi roll out new $10‑$50 promo codes for UFC, MLB, NFL, NBA and World Cup betting

Polymarket promo code Kalshi bonus sports prediction markets UFC Fight Night World Cup finals

Polymarket is offering several limited‑time promo codes that grant new users a $50 trading bonus when they deposit $20. The ALCOM code applies to the UFC Fight Night main event between Dricus Du Plessis and Kamaru Usman in Oklahoma City. The NJCOM code can be used to trade futures on the San Francisco 49ers or to back the Spain vs Argentina World Cup final at MetLife Stadium. A separate MASS code provides a $50 bonus for NBA Summer‑League and MLB markets.

Kalshi is also promoting new welcome offers. The TSN15 and BROAD15 codes give a $15 bonus after a $10 trade on MLB games, while the ALCOM15 code provides a $15 bonus for Seattle Seahawks futures ahead of NFL training camp. The OREGONLIVE1 code adds a $10 cash bonus for new users who make a $10 trade on post‑All‑Star‑break MLB matchups.

All promotions require users to be at least 18 years old, reside in a qualifying U.S. state, and meet the minimum deposit or trade thresholds before the bonus is credited. The offers are limited to new account holders and are intended for prediction‑market trading rather than traditional sportsbook wagering.
