Kalshi and Polymarket unveil bonus codes for US sports prediction markets

Prediction‑market platforms Kalshi and Polymarket are rolling out new promotional codes that give new U.S. users bonus trading credits. Kalshi’s codes (e.g., MLIVE, SILIVE, ALCOM) can provide up to $500 in credit after a $25 trade, while Polymarket’s codes (e.g., NJCOM, CUSE, MASS, ELITE) grant $20‑$50 bonuses after a $10‑$20 deposit. The offers target a range of sports futures, including Michigan Wolverines football, NFL championships, MLB games such as the Yankees‑Phillies matchup, the PGA 3M Open, UFC Fight Night, and WNBA contests. All promotions require users to be at least 18 years old, to verify identity, and to reside in a state where the platform is legally operating. The bonuses are applied as trading funds that can be used on any of the platforms’ prediction contracts, which are regulated by the U.S. Commodity Futures Trading Commission and operate under designated contract market rules.
