The prediction market platform Kalshi is offering new users a promotional bonus of $15 when they sign up and make at least $10 in trades. This offer can be utilized with the promo code NYPMAX. The bonus value can be applied to various markets on the platform, including sports events like Wimbledon, the World Cup, and MLB, as well as non-sports contracts such as politics and weather.

Kalshi allows users to buy and sell contracts based on the outcomes of future events. The price of these contracts fluctuates, reflecting the crowd's estimation of the probability of a particular event occurring. For instance, a contract priced at $0.65 suggests a 65% perceived chance of that outcome happening.

The promotion is available in numerous U.S. states and territories, including Alabama, California, New York, Texas, and Washington D.C. Users must be at least 18 years old with a legal U.S. residential address in an applicable state, district, or territory. However, the promotion is not available in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, and Ohio.
