Kalshi and ProphetX offer promotions for NFL preseason trading

Prediction market platforms Kalshi and ProphetX are offering promotional incentives for users to trade on the upcoming first week of the NFL preseason.

Kalshi is providing a bonus credit of up to $500 for new registrants who trade at least $25. The platform operates as a financial exchange where users trade on sporting outcomes, such as preseason games and conference championship winners, using ‘Yes’ and ‘No’ contracts. Unlike traditional sportsbooks, users trade against each other rather than the house.

ProphetX is offering a $20 bonus to new customers who deposit and trade at least $10. Similar to Kalshi, ProphetX functions as a prediction market rather than a sportsbook, displaying trading prices and percentages to indicate favorites. Both platforms require users to be at least 18 years old and located in qualifying states.
